feat(hooks): spill oversized hook-injected context to disk

Port from openai/codex#21069 ("Spill large hook outputs from context"). Both shell hooks and Python plugins can return {"context": "..."} from pre_llm_call, which gets appended to the current turn's user message on every subsequent API call. A plugin that accidentally (or intentionally) emits a large blob inflates every turn and blows out the prompt cache prefix. This adds a per-hook context cap with disk spill: - tools/hook_output_spill.py: shared helper that writes oversized context to $HERMES_HOME/hook_outputs/<session_id>/<uuid>.txt and returns a head/tail preview plus the saved path. - run_agent.py: apply the cap at the pre_llm_call aggregation site, covering both Python plugins and shell hooks (which also flow through invoke_hook). - agent/shell_hooks.py: reserve output_spill as a sub-key under hooks: so the config is schema-friendly and doesn't emit "unknown hook event" warnings. - Docs: document the cap and config in build-a-hermes-plugin.md. Config (all optional, behaviour-preserving when absent): hooks: output_spill: enabled: true # default: true max_chars: 10000 # default preview_head: 500 # default preview_tail: 500 # default directory: null # default: $HERMES_HOME/hook_outputs Never raises — spill write failures fall back to a preview-only string so the model still gets bounded context even if the disk is full. Tests: 14 new unit tests in tests/tools/test_hook_output_spill.py; existing tests/agent/test_shell_hooks.py (49 tests) and tests/hermes_cli/test_plugins.py (62 tests) still pass. E2E validated with an isolated HERMES_HOME. Source: https://github.com/openai/codex/pull/21069

-name: uv.lock check
-
-# Verify uv.lock is in sync with pyproject.toml.  Blocking check — PRs
-# that modify pyproject.toml without regenerating uv.lock (or vice versa)
-# must not merge, because the Docker build's `uv sync --frozen` step will
-# fail on a stale lockfile and we'd rather catch it here than in the
-# docker-publish workflow on main.
-#
-# ─────────────────────────────────────────────────────────────────────────
-# IMPORTANT: this check runs against the MERGED state, not just your branch
-# ─────────────────────────────────────────────────────────────────────────
-#
-# For `pull_request` events, GitHub checks out `refs/pull/<N>/merge` by
-# default — a synthetic commit that merges your PR branch into the CURRENT
-# state of `main`.  That means the pyproject.toml evaluated here is
-# `main's pyproject.toml + your PR's changes to pyproject.toml`, not just
-# what's on your branch.
-#
-# Failure mode this creates: if `main` has advanced since you branched
-# (e.g. someone merged a PR that added a dep to pyproject.toml + its
-# corresponding uv.lock entries), your branch's uv.lock is missing those
-# new entries.  `uv lock --check` resolves against the merged pyproject
-# and sees a lockfile that doesn't cover all the current deps → fails
-# with "The lockfile at uv.lock needs to be updated."
-#
-# This can be confusing: `uv lock --check` passes locally (your branch
-# is internally consistent) but fails in CI (merged state isn't).
-#
-# Fix is to sync your branch with main and regenerate the lockfile:
-#
-#     git fetch origin main
-#     git rebase origin/main      # or merge, whatever the repo prefers
-#     uv lock                     # regenerates uv.lock against new pyproject.toml
-#     git add uv.lock
-#     git commit -m "chore: refresh uv.lock after rebase onto main"
-#     git push --force-with-lease # if you rebased
-#
-# If you also changed pyproject.toml in your PR, `uv lock` handles that
-# at the same time — one regeneration covers both your changes and the
-# drift from main.
-#
-# This is the correct behavior!  The check is protecting main's Docker
-# build: a post-merge build would see the same merged state and fail
-# the same way.  Better to catch it here than after merge.

 ## Cross-Platform Compatibility

-Hermes runs on Linux, macOS, and native Windows (plus WSL2). When writing code
-that touches the OS, assume *any* platform can hit your code path.

-> **Before you PR:** run `scripts/check-windows-footguns.py` to catch the
-> common Windows-unsafe patterns in your diff. It's grep-based and cheap;
-> CI runs it on every PR too.
+Hermes runs on Linux, macOS, and WSL2 on Windows. When writing code that touches the OS:

 ### Critical rules

-1. **Never call `os.kill(pid, 0)` for liveness checks.** `os.kill(pid, 0)`
-   is a standard POSIX idiom to check "is this PID alive" — the signal 0
-   is a no-op permission check. **On Windows it is NOT a no-op.** Python's
-   Windows `os.kill` maps `sig=0` to `CTRL_C_EVENT` (they collide at the
-   integer value 0) and routes it through `GenerateConsoleCtrlEvent(0, pid)`,
-   which broadcasts Ctrl+C to the **entire console process group** containing
-   the target PID. "Probe if alive" silently becomes "kill the target and
-   often unrelated processes sharing its console." See [bpo-14484](https://bugs.python.org/issue14484)
-   (open since 2012 — will never be fixed for compat reasons).
-
-   **Preferred:** use `psutil` (a core dependency — always available):
-
-   ```python
-   import psutil
-   if psutil.pid_exists(pid):
-       # process is alive — safe on every platform
-       ...
-   ```
-
-   If you specifically need the hermes wrapper (it has a stdlib fallback
-   for scaffold-phase imports before pip install finishes), use
-   `gateway.status._pid_exists(pid)`. It calls `psutil.pid_exists` first
-   and falls back to a hand-rolled `OpenProcess + WaitForSingleObject`
-   dance on Windows only when psutil is somehow missing.
-
-   Audit grep for new callsites: `rg "os\.kill\([^,]+,\s*0\s*\)"`. Any hit
-   in non-test code is presumptively a Windows silent-kill bug.
-
-2. **Use `shutil.which()` before shelling out — don't assume Windows has
-   tools Linux has.** `wmic` was removed in Windows 10 21H1 and later. `ps`,
-   `kill`, `grep`, `awk`, `fuser`, `lsof`, `pgrep`, and most POSIX CLI tools
-   simply don't exist on Windows. Test availability with
-   `shutil.which("tool")` and fall back to a Windows-native equivalent —
-   usually PowerShell via `subprocess.run(["powershell", "-NoProfile",
-   "-Command", ...])`.
-
-   For process enumeration: PowerShell's `Get-CimInstance Win32_Process` is
-   the modern replacement for `wmic process`. See
-   `hermes_cli/gateway.py::_scan_gateway_pids` for the pattern.
-
-3. **`termios` and `fcntl` are Unix-only.** Always catch both `ImportError`
-   and `NotImplementedError`:

   ```python

   ```
-   Config files (`config.yaml`) may be saved with a UTF-8 BOM by Notepad and
-   similar editors — use `encoding="utf-8-sig"` when reading files that
-   could have been touched by a Windows GUI editor.

-5. **Process management.** `os.setsid()`, `os.killpg()`, `os.fork()`,
-   `os.getuid()`, and POSIX signal handling differ on Windows. Guard with
-   `platform.system()`, `sys.platform`, or `hasattr(os, "setsid")`:
+3. **Process management.** `os.setsid()`, `os.killpg()`, and signal handling differ on Windows. Use platform checks:
   ```python
+   import platform
   if platform.system() != "Windows":
       kwargs["preexec_fn"] = os.setsid
-   else:
-       kwargs["creationflags"] = subprocess.CREATE_NEW_PROCESS_GROUP
   ```

-   **Preferred:** for killing a process AND its children (what `os.killpg`
-   does on POSIX), use `psutil` — it works on every platform:
-   ```python
-   import psutil
-   try:
-       parent = psutil.Process(pid)
-       # Kill children first (leaf-up), then the parent.
-       for child in parent.children(recursive=True):
-           child.kill()
-       parent.kill()
-   except psutil.NoSuchProcess:
-       pass
-   ```
+4. **Path separators.** Use `pathlib.Path` instead of string concatenation with `/`.

-6. **Signals that don't exist on Windows: `SIGALRM`, `SIGCHLD`, `SIGHUP`,
-   `SIGUSR1`, `SIGUSR2`, `SIGPIPE`, `SIGQUIT`, `SIGKILL`.** Python's
-   `signal` module raises `AttributeError` at import time if you reference
-   them on Windows. Use `getattr(signal, "SIGKILL", signal.SIGTERM)` or
-   gate the whole block behind a platform check. `loop.add_signal_handler`
-   raises `NotImplementedError` on Windows — always catch it.
-
-7. **Path separators.** Use `pathlib.Path` instead of string concatenation
-   with `/`. Forward slashes work almost everywhere on Windows, but
-   `subprocess.run(["cmd.exe", "/c", ...])` and other shell contexts can
-   require backslashes — convert with `str(path)` at the subprocess boundary,
-   not inside Python logic.
-
-8. **Symlinks need elevated privileges on Windows** (unless Developer Mode is
-   on). Tests that create symlinks need `@pytest.mark.skipif(sys.platform ==
-   "win32", reason="Symlinks require elevated privileges on Windows")`.
-
-9. **POSIX file modes (0o600, 0o644, etc.) are NOT enforced on NTFS** by
-   default. Tests that assert on `stat().st_mode & 0o777` must skip on
-   Windows — the concept doesn't translate. Use ACLs (`icacls`, `pywin32`)
-   for Windows secret-file protection if needed.
-
-10. **Detached background daemons on Windows need `pythonw.exe`, NOT
-    `python.exe`.** `python.exe` always allocates or attaches to a console,
-    which makes it vulnerable to `CTRL_C_EVENT` broadcasts from any sibling
-    process. `pythonw.exe` is the no-console variant. Combine with
-    `CREATE_NO_WINDOW | DETACHED_PROCESS | CREATE_NEW_PROCESS_GROUP |
-    CREATE_BREAKAWAY_FROM_JOB` in `subprocess.Popen(creationflags=...)`.
-    See `hermes_cli/gateway_windows.py::_spawn_detached` for the reference
-    implementation.
-
-11. **`subprocess.Popen` with `.cmd` or `.bat` shims needs `shutil.which`
-    to resolve.** Passing `"agent-browser"` to `Popen` on Windows finds
-    the extensionless POSIX shebang shim in `node_modules/.bin/`, which
-    `CreateProcessW` can't execute — you'll get `WinError 193 "not a valid
-    Win32 application"`. Use `shutil.which("agent-browser", path=local_bin)`
-    which honors PATHEXT and picks the `.CMD` variant on Windows.
-
-12. **Don't use shell shebangs as a way to run Python.** `#!/usr/bin/env
-    python` only works when the file is executed through a Unix shell.
-    `subprocess.run(["./myscript.py"])` on Windows fails even if the file
-    has a shebang line. Always invoke Python explicitly:
-    `[sys.executable, "myscript.py"]`.
-
-13. **Shell commands in installers.** If you change `scripts/install.sh`,
-    make the equivalent change in `scripts/install.ps1`. The two scripts
-    are the canonical example of "works on Linux does not mean works on
-    Windows" and have drifted multiple times — keep them in lockstep.
-
-14. **Known paths that are OneDrive-redirected on Windows:** Desktop,
-    Documents, Pictures, Videos. The "real" path when OneDrive Backup is
-    enabled is `%USERPROFILE%\OneDrive\Desktop` (etc.), NOT
-    `%USERPROFILE%\Desktop` (which exists as an empty husk). Resolve the
-    real location via `ctypes` + `SHGetKnownFolderPath` or by reading the
-    `Shell Folders` registry key — never assume `~/Desktop`.
-
-15. **CRLF vs LF in generated scripts.** Windows `cmd.exe` and `schtasks`
-    parse line-by-line; mixed or LF-only line endings can break multi-line
-    `.cmd` / `.bat` files. Use `open(path, "w", encoding="utf-8",
-    newline="\r\n")` — or `open(path, "wb")` + explicit bytes — when
-    generating scripts Windows will execute.
-
-16. **Two different quoting schemes in one command line.** `subprocess.run
-    (["schtasks", "/TR", some_cmd])` → schtasks itself parses `/TR`, AND
-    the `some_cmd` string is re-parsed by `cmd.exe` when the task fires.
-    Different parsers, different escape rules. Use two separate quoting
-    helpers and never cross them. See `hermes_cli/gateway_windows.py::
-    _quote_cmd_script_arg` and `_quote_schtasks_arg` for the reference
-    pair.
-
-### Testing cross-platform
-
-Tests that use POSIX-only syscalls need a skip marker. Common ones:
- Symlinks → `@pytest.mark.skipif(sys.platform == "win32", ...)`
- `0o600` file modes → `@pytest.mark.skipif(sys.platform.startswith("win"), ...)`
- `signal.SIGALRM` → Unix-only (see `tests/conftest.py::_enforce_test_timeout`)
- `os.setsid` / `os.fork` → Unix-only
- Live Winsock / Windows-specific regression tests →
-  `@pytest.mark.skipif(sys.platform != "win32", reason="Windows-specific regression")`
-
-If you monkeypatch `sys.platform` for cross-platform tests, also patch
-`platform.system()` / `platform.release()` / `platform.mac_ver()` — each
-re-reads the real OS independently, so half-patched tests still route
-through the wrong branch on a Windows runner.

-> The Tenacity Release — Hermes Agent now finishes what it starts. Kanban ships as a durable multi-agent board (heartbeat, reclaim, zombie detection, auto-block on incomplete exit, per-task retries, hallucination recovery). `/goal` keeps the agent locked on a target across turns (Ralph loop). Checkpoints v2 rewrites state persistence with real pruning. Gateway auto-resumes interrupted sessions after restart. Cron grows a `no_agent` watchdog mode. A security wave closes 8 P0s — redaction is now ON by default, Discord role-allowlists are guild-scoped, WhatsApp rejects strangers by default, and TOCTOU windows close across auth.json and MCP OAuth. Google Chat becomes the 20th platform. Providers become a pluggable surface. Seven i18n locales ship.

Heartbeats, reclaim, zombie detection, retry budgets, and a hallucination gate keep the team honest. One install, many kanbans. ([#17805](https://github.com/NousResearch/hermes-agent/pull/17805), [#19653](https://github.com/NousResearch/hermes-agent/pull/19653), [#20232](https://github.com/NousResearch/hermes-agent/pull/20232), [#20332](https://github.com/NousResearch/hermes-agent/pull/20332), [#21330](https://github.com/NousResearch/hermes-agent/pull/21330), [#21183](https://github.com/NousResearch/hermes-agent/pull/21183), [#21214](https://github.com/NousResearch/hermes-agent/pull/21214))
-
- **`/goal` — the agent doesn't forget what you asked it to do** — Lock the agent onto a target and it stays on task across turns. The Ralph loop as a first-class primitive. ([#18262](https://github.com/NousResearch/hermes-agent/pull/18262), [#18275](https://github.com/NousResearch/hermes-agent/pull/18275), [#21287](https://github.com/NousResearch/hermes-agent/pull/21287))
-
- **Show it a video** — new `video_analyze` tool for native video understanding on Gemini and compatible multimodal models. (@alt-glitch) ([#19301](https://github.com/NousResearch/hermes-agent/pull/19301))
-
- **Clone a voice** — xAI Custom Voices lands as a TTS provider with voice cloning support. (@alt-glitch) ([#18776](https://github.com/NousResearch/hermes-agent/pull/18776))
-
- **Hermes speaks your language** — static gateway + CLI messages translate to 7 locales: Chinese, Japanese, German, Spanish, French, Ukrainian, and Turkish. Docs site gains a Chinese (zh-Hans) locale. ([#20231](https://github.com/NousResearch/hermes-agent/pull/20231), [#20329](https://github.com/NousResearch/hermes-agent/pull/20329), [#20467](https://github.com/NousResearch/hermes-agent/pull/20467), [#20474](https://github.com/NousResearch/hermes-agent/pull/20474), [#20430](https://github.com/NousResearch/hermes-agent/pull/20430), [#20431](https://github.com/NousResearch/hermes-agent/pull/20431))
-
- **Google Chat — the 20th messaging platform** — plus a generic platform-plugin hooks surface so third-party adapters drop in without touching core (IRC and Teams migrated). ([#21306](https://github.com/NousResearch/hermes-agent/pull/21306), [#21331](https://github.com/NousResearch/hermes-agent/pull/21331))
-
- **Sessions survive restarts** — gateway bounces mid-agent, `/update` restarts, source-file reloads — conversations auto-resume when the gateway comes back. ([#21192](https://github.com/NousResearch/hermes-agent/pull/21192))
-
- **Security wave — 8 P0 closures** — redaction ON by default, Discord role-allowlists guild-scoped (CVSS 8.1 cross-guild DM bypass closed), WhatsApp rejects strangers by default, TOCTOU windows closed across `auth.json` and MCP OAuth, browser enforces cloud-metadata SSRF floor, cron prompt-injection scans assembled skill content, `hermes debug share` redacts at upload. ([#21193](https://github.com/NousResearch/hermes-agent/pull/21193), [#21241](https://github.com/NousResearch/hermes-agent/pull/21241), [#21291](https://github.com/NousResearch/hermes-agent/pull/21291), [#21176](https://github.com/NousResearch/hermes-agent/pull/21176), [#21194](https://github.com/NousResearch/hermes-agent/pull/21194), [#21228](https://github.com/NousResearch/hermes-agent/pull/21228), [#21350](https://github.com/NousResearch/hermes-agent/pull/21350), [#19318](https://github.com/NousResearch/hermes-agent/pull/19318))
-
- **Checkpoints v2** — state persistence rewritten. Real pruning, disk guardrails, no more orphan shadow repos. ([#20709](https://github.com/NousResearch/hermes-agent/pull/20709))
-
- **The agent lints its own writes** — post-write delta lint on `write_file` + `patch`. Python, JSON, YAML, TOML. Syntax errors surface immediately instead of shipping downstream. ([#20191](https://github.com/NousResearch/hermes-agent/pull/20191))
-
- **`no_agent` cron mode — script-only watchdog** — cron jobs can now skip the agent entirely and just run a script. Empty stdout is silent, non-empty gets delivered verbatim. ([#19709](https://github.com/NousResearch/hermes-agent/pull/19709))
-
- **Platform allowlists everywhere** — `allowed_channels` / `allowed_chats` / `allowed_rooms` config across Slack, Telegram, Mattermost, Matrix, and DingTalk. ([#21251](https://github.com/NousResearch/hermes-agent/pull/21251))
-
- **Providers are now plugins** — `ProviderProfile` ABC + `plugins/model-providers/`. Drop in third-party providers without touching core. ([#20324](https://github.com/NousResearch/hermes-agent/pull/20324))
-
- **API server — long-term memory per session** — `X-Hermes-Session-Key` header gives memory providers a stable session identifier. ([#20199](https://github.com/NousResearch/hermes-agent/pull/20199))
-
- **MCP levels up** — SSE transport with OAuth forwarding, stale-pipe retries, image results surface as MEDIA tags instead of getting dropped, keepalive on long-lived lifecycle waits. ([#21227](https://github.com/NousResearch/hermes-agent/pull/21227), [#21323](https://github.com/NousResearch/hermes-agent/pull/21323), [#21289](https://github.com/NousResearch/hermes-agent/pull/21289), [#21328](https://github.com/NousResearch/hermes-agent/pull/21328), [#20209](https://github.com/NousResearch/hermes-agent/pull/20209))
-
- **Curator grows subcommands** — `hermes curator archive`, `prune`, `list-archived`. Manual `hermes curator run` is synchronous now — you see results without polling. ([#20200](https://github.com/NousResearch/hermes-agent/pull/20200), [#21236](https://github.com/NousResearch/hermes-agent/pull/21236), [#21216](https://github.com/NousResearch/hermes-agent/pull/21216))
-
- **ACP — `/steer` and `/queue`** — direct the in-flight agent or queue follow-ups from Zed, VS Code, or JetBrains. Plus atomic session persistence and reasoning-metadata preservation across restarts. (@HenkDz) ([#18114](https://github.com/NousResearch/hermes-agent/pull/18114), [#20279](https://github.com/NousResearch/hermes-agent/pull/20279), [#20296](https://github.com/NousResearch/hermes-agent/pull/20296), [#20433](https://github.com/NousResearch/hermes-agent/pull/20433))
-
- **TUI glow-up** — `/model` picker matches `hermes model` with inline auth (@austinpickett), collapsible startup banner sections (@kshitijk4poor), context-compression counter in the status bar. ([#18117](https://github.com/NousResearch/hermes-agent/pull/18117), [#20625](https://github.com/NousResearch/hermes-agent/pull/20625), [#21218](https://github.com/NousResearch/hermes-agent/pull/21218))
-
- **Dashboard grows up** — Plugins page (manage, enable/disable, auth status) (@austinpickett), Profiles management page (@vincez-hms-coder), sortable analytics tables, reverse-proxy support via `X-Forwarded-Prefix`, new `default-large` 18px theme. ([#18095](https://github.com/NousResearch/hermes-agent/pull/18095), [#16419](https://github.com/NousResearch/hermes-agent/pull/16419), [#18192](https://github.com/NousResearch/hermes-agent/pull/18192), [#21296](https://github.com/NousResearch/hermes-agent/pull/21296), [#20820](https://github.com/NousResearch/hermes-agent/pull/20820))
-
- **SearXNG + split web tools** — SearXNG ships as a native search-only backend; web tools now let you pick different backends per capability (search vs extract vs browse). (@kshitijk4poor) ([#20823](https://github.com/NousResearch/hermes-agent/pull/20823), [#20061](https://github.com/NousResearch/hermes-agent/pull/20061), [#20841](https://github.com/NousResearch/hermes-agent/pull/20841))
-
- **OpenRouter response caching** — explicit cache control for models that expose it. (@kshitijk4poor) ([#19132](https://github.com/NousResearch/hermes-agent/pull/19132))
-
- **`[[as_document]]` — skill media-routing directive** — skills can force the gateway to deliver output as a document on platforms that support it. ([#21210](https://github.com/NousResearch/hermes-agent/pull/21210))
-
- **`transform_llm_output` plugin hook** — new lifecycle hook that lets plugins reshape or filter LLM output before it hits the conversation. Useful for context-window reducers and content filters. ([#21235](https://github.com/NousResearch/hermes-agent/pull/21235))
-
- **Nous OAuth persists across profiles** — shared token store: sign in once, every profile inherits the session. ([#19712](https://github.com/NousResearch/hermes-agent/pull/19712))
-
- **QQBot — native approval keyboards** — feature parity with Telegram / Discord approval UX. Chunked upload, quoted attachments. ([#21342](https://github.com/NousResearch/hermes-agent/pull/21342), [#21353](https://github.com/NousResearch/hermes-agent/pull/21353))
-
- **6 new optional skills** — Shopify (Admin + Storefront GraphQL), here.now, shop-app personal shopping assistant, Anthropic financial-services bundle, kanban-video-orchestrator (@SHL0MS), searxng-search (@kshitijk4poor). ([#18116](https://github.com/NousResearch/hermes-agent/pull/18116), [#18170](https://github.com/NousResearch/hermes-agent/pull/18170), [#20702](https://github.com/NousResearch/hermes-agent/pull/20702), [#21180](https://github.com/NousResearch/hermes-agent/pull/21180), [#19281](https://github.com/NousResearch/hermes-agent/pull/19281), [#20841](https://github.com/NousResearch/hermes-agent/pull/20841))
-
- **New models** — `deepseek/deepseek-v4-pro`, `x-ai/grok-4.3`, `openrouter/owl-alpha` (free), `tencent/hy3-preview` (@Contentment003111), Arcee Trinity Large Thinking temperature + compression overrides.

-
- **100 fresh CLI startup tips** — the random tip banner gets 100 new entries covering cron, kanban, curator, plugins, and lesser-known flags. ([#20168](https://github.com/NousResearch/hermes-agent/pull/20168))

 # Hermes Agent Security Policy

-This document describes Hermes Agent's trust model, names the one
-security boundary the project treats as load-bearing, and defines the
-scope for vulnerability reports.
+This document outlines the security protocols, trust model, and deployment hardening guidelines for the **Hermes Agent** project.

-## 1. Reporting a Vulnerability
+## 1. Vulnerability Reporting

-Report privately via [GitHub Security Advisories](https://github.com/NousResearch/hermes-agent/security/advisories/new)
-or **security@nousresearch.com**. Do not open public issues for
-security vulnerabilities. **Hermes Agent does not operate a bug
-bounty program.**
+Hermes Agent does **not** operate a bug bounty program. Security issues should be reported via [GitHub Security Advisories (GHSA)](https://github.com/NousResearch/hermes-agent/security/advisories/new) or by emailing **security@nousresearch.com**. Do not open public issues for security vulnerabilities.

-A useful report includes:
-
- A concise description and severity assessment.
- The affected component, identified by file path and line range
-  (e.g. `path/to/file.py:120-145`).
- Environment details (`hermes version`, commit SHA, OS, Python
-  version).
- A reproduction against `main` or the latest release.
- A statement of which trust boundary in §2 is crossed.
-
-Please read §2 and §3 before submitting. Reports that demonstrate
-limits of an in-process heuristic this policy does not treat as a
-boundary will be closed as out-of-scope under §3 — but see §3.2:
-they are still welcome as regular issues or pull requests, just not
-through the private security channel.
+### Required Submission Details
+- **Title & Severity:** Concise description and CVSS score/rating.
+- **Affected Component:** Exact file path and line range (e.g., `tools/approval.py:120-145`).
+- **Environment:** Output of `hermes version`, commit SHA, OS, and Python version.
+- **Reproduction:** Step-by-step Proof-of-Concept (PoC) against `main` or the latest release.
+- **Impact:** Explanation of what trust boundary was crossed.

 ---

 ## 2. Trust Model

-Hermes Agent is a single-tenant personal agent. Its posture is
-layered, and the layers are not equally load-bearing. Reporters and
-operators should reason about them in the same terms.
+The core assumption is that Hermes is a **personal agent** with one trusted operator.

-### 2.1 Definitions
+### Operator & Session Trust
+- **Single Tenant:** The system protects the operator from LLM actions, not from malicious co-tenants. Multi-user isolation must happen at the OS/host level.
+- **Gateway Security:** Authorized callers (Telegram, Discord, Slack, etc.) receive equal trust. Session keys are used for routing, not as authorization boundaries.
+- **Execution:** Defaults to `terminal.backend: local` (direct host execution). Container isolation (Docker, Modal, Daytona) is opt-in for sandboxing.

- **Agent process.** The Python interpreter running Hermes Agent,
-  including any Python modules it has loaded (skills, plugins,
-  hook handlers).
- **Terminal backend.** A pluggable execution target for the
-  `terminal()` tool. The default runs commands directly on the host.
-  Other backends run commands inside a container, cloud sandbox, or
-  remote host.
- **Input surface.** Any channel through which content enters the
-  agent's context: operator input, web fetches, email, gateway
-  messages, file reads, MCP server responses, tool results.
- **Trust envelope.** The set of resources an operator has implicitly
-  granted Hermes Agent access to by running it — typically, whatever
-  the operator's own user account can reach on the host.
- **Stance.** An explicit statement in Hermes Agent's documentation
-  or code about how a consuming layer (adapter, UI, file writer,
-  shell) should treat agent output — e.g. "the dashboard renders
-  agent output as inert HTML."
+### Dangerous Command Approval
+The approval system (`tools/approval.py`) is a core security boundary. Terminal commands, file operations, and other potentially destructive actions are gated behind explicit user confirmation before execution. The approval mode is configurable via `approvals.mode` in `config.yaml`:
+- `"on"` (default) — prompts the user to approve dangerous commands.
+- `"auto"` — auto-approves after a configurable delay.
+- `"off"` — disables the gate entirely (break-glass; see Section 3).

-### 2.2 The Boundary: OS-Level Isolation
+### Output Redaction
+`agent/redact.py` strips secret-like patterns (API keys, tokens, credentials) from all display output before it reaches the terminal or gateway platform. This prevents accidental credential leakage in chat logs, tool previews, and response text. Redaction operates on the display layer only — underlying values remain intact for internal agent operations.

-**The only security boundary against an adversarial LLM is the
-operating system.** Nothing inside the agent process constitutes
-containment — not the approval gate, not output redaction, not any
-pattern scanner, not any tool allowlist. Any in-process component
-that screens LLM output is a heuristic operating on an
-attacker-influenced string, and this policy treats it as such.
+### Skills vs. MCP Servers
+- **Installed Skills:** High trust. Equivalent to local host code; skills can read environment variables and run arbitrary commands.
+- **MCP Servers:** Lower trust. MCP subprocesses receive a filtered environment (`_build_safe_env()` in `tools/mcp_tool.py`) — only safe baseline variables (`PATH`, `HOME`, `XDG_*`) plus variables explicitly declared in the server's `env` config block are passed through. Host credentials are stripped by default. Additionally, packages invoked via `npx`/`uvx` are checked against the OSV malware database before spawning.

-Hermes Agent supports two OS-level isolation postures. They address
-different threats and an operator should choose deliberately.
+### Code Execution Sandbox
+The `execute_code` tool (`tools/code_execution_tool.py`) runs LLM-generated Python scripts in a child process with API keys and tokens stripped from the environment to prevent credential exfiltration. Only environment variables explicitly declared by loaded skills (via `env_passthrough`) or by the user in `config.yaml` (`terminal.env_passthrough`) are passed through. The child accesses Hermes tools via RPC, not direct API calls.

-#### Terminal-backend isolation
-
-A non-default terminal backend runs LLM-emitted shell commands
-inside a container, remote host, or cloud sandbox. The file tools
-(`read_file`, `write_file`, `patch`) also run through this backend,
-since they are implemented on top of the shell contract — they
-cannot reach paths the backend doesn't expose.
-
-What this confines: anything the agent does by issuing shell or
-file operations. What this does **not** confine: everything the
-agent does in its own Python process. That includes the
-code-execution tool (spawned as a host subprocess), MCP subprocesses
-(spawned from the agent's environment), plugin loading, hook
-dispatch, and skill loading (all imported into the agent
-interpreter).
-
-Terminal-backend isolation is the right posture when the concern is
-LLM-emitted destructive shell or unwanted file-tool writes, and the
-operator is otherwise trusted.
-
-#### Whole-process wrapping
-
-Whole-process wrapping runs the entire agent process tree inside a
-sandbox. Every code path — shell, code-execution, MCP, file tools,
-plugins, hooks, skill loading — is subject to the same filesystem,
-network, process, and (where applicable) inference policy.
-
-Hermes Agent supports this in two ways:
-
- **Hermes Agent's own Docker image and Compose setup.** Lighter-
-  weight; the agent runs in a standard container with operator-
-  configured mounts and network policy.
- **[NVIDIA OpenShell](https://github.com/NVIDIA/OpenShell)**.
-  OpenShell provides per-session sandboxes with declarative policy
-  across filesystem, network (L7 egress), process/syscall, and
-  inference-routing layers. Network and inference policies are
-  hot-reloadable. Credentials are injected from a Provider store
-  and never touch the sandbox filesystem.
-
-Under a whole-process wrapper, Hermes Agent's in-process heuristics
-(§2.4) function as accident-prevention layered on top of a real
-boundary. This is the supported posture when the agent ingests
-content from surfaces the operator does not control — the open web,
-inbound email, multi-user channels, untrusted MCP servers — and for
-production or shared deployments.
-
-Operators running the default local backend with untrusted input
-surfaces, or running a terminal-backend sandbox and expecting it to
-contain code paths that don't go through the shell, are operating
-outside the supported security posture.
-
-### 2.3 Credential Scoping
-
-Hermes Agent filters the environment it passes to its lower-trust
-in-process components: shell subprocesses, MCP subprocesses, and
-the code-execution child. Credentials like provider API keys and
-gateway tokens are stripped by default; variables explicitly
-declared by the operator or by a loaded skill are passed through.
-
-This reduces casual exfiltration. It is not containment. Any
-component running inside the agent process (skills, plugins, hook
-handlers) can read whatever the agent itself can read, including
-in-memory credentials. The mitigation against a compromised
-in-process component is operator review before install (§2.4,
-§2.5), not environment scrubbing.
-
-### 2.4 In-Process Heuristics
-
-The following components screen or warn about LLM behavior. They
-are useful. They are not boundaries.
-
- The **approval gate** detects common destructive shell patterns
-  and prompts the operator before execution. Shell is Turing-
-  complete; a denylist over shell strings is structurally
-  incomplete. The gate catches cooperative-mode mistakes, not
-  adversarial output.
- **Output redaction** strips secret-like patterns from display.
-  A motivated output producer will defeat it.
- **Skills Guard** scans installable skill content for injection
-  patterns. It is a review aid; the boundary for third-party skills
-  is operator review before install. Reviewing a skill means
-  reading its Python code and scripts, not just its SKILL.md
-  description — skills execute arbitrary Python at import time.
-
-### 2.5 Plugin Trust Model
-
-Plugins load into the agent process and run with full agent
-privileges: they can read the same credentials, call the same
-tools, register the same hooks, and import the same modules as
-anything shipped in-tree. The boundary for third-party plugins is
-operator review before install — the same rule as skills (§2.4),
-called out separately because plugins are architecturally heavier
-and often ship their own background services, network listeners,
-and dependencies.
-
-A malicious or buggy plugin is not a vulnerability in Hermes Agent
-itself. Bugs in Hermes Agent's plugin-install or plugin-discovery
-path that prevent the operator from seeing what they're installing
-are in scope under §3.1.
-
-### 2.6 External Surfaces
-
-An **external surface** is any channel outside the local agent
-process through which a caller can dispatch agent work, resolve
-approvals, or receive agent output. Each surface has its own
-authorization model, but the rules below apply uniformly.
-
-**Surfaces in Hermes Agent:**
-
- **Gateway platform adapters.** Messaging integrations in
-  `gateway/platforms/` (Telegram, Discord, Slack, email, SMS, etc.)
-  and analogous adapters shipped as plugins.
- **Network-exposed HTTP surfaces.** The API server adapter, the
-  dashboard plugin, the kanban plugin's HTTP endpoints, and any
-  other plugin that binds a listening socket.
- **Editor / IDE adapters.** The ACP adapter (`acp_adapter/`) and
-  equivalent integrations that accept requests from a local client
-  process.
- **The TUI gateway (`tui_gateway/`).** JSON-RPC backend for the
-  Ink terminal UI, reached over local IPC.
-
-**Uniform rules:**
-
-1. **Authorization is required at every surface that crosses a
-   trust boundary.** For messaging and network HTTP surfaces, the
-   boundary is the network: authorization means an operator-
-   configured caller allowlist. For editor and local-IPC surfaces
-   (ACP, TUI gateway), the boundary is the host's user account:
-   authorization means relying on OS-level access control (file
-   permissions, loopback-only binds) and not exposing the surface
-   beyond the local user without an explicit network auth layer.
-2. **An allowlist is required for every enabled network-exposed
-   adapter.** Adapters must refuse to dispatch agent work, resolve
-   approvals, or relay output until an allowlist is set. Code paths
-   that fail open when no allowlist is configured are code bugs in
-   scope under §3.1.
-3. **Session identifiers are routing handles, not authorization
-   boundaries.** Knowing another caller's session ID does not grant
-   access to their approvals or output; authorization is always
-   re-checked against the allowlist (or OS-level equivalent).
-4. **Within the authorized set, all callers are equally trusted.**
-   Hermes Agent does not model per-caller capabilities inside a
-   single adapter. Operators who need capability separation should
-   run separate agent instances with separate allowlists.
-5. **Binding a local-only surface to a non-loopback interface is a
-   break-glass operator decision (§3.2).** The dashboard and other
-   plugin HTTP servers default to loopback; exposing them via
-   `--host 0.0.0.0` or equivalent makes public-exposure hardening
-   (§4) the operator's responsibility.
+### Subagents
+- **No recursive delegation:** The `delegate_task` tool is disabled for child agents.
+- **Depth limit:** `MAX_DEPTH = 2` — parent (depth 0) can spawn a child (depth 1); grandchildren are rejected.
+- **Memory isolation:** Subagents run with `skip_memory=True` and do not have access to the parent's persistent memory provider. The parent receives only the task prompt and final response as an observation.

-## 3. Scope
+## 3. Out of Scope (Non-Vulnerabilities)

-### 3.1 In Scope
-
- Escape from a declared OS-level isolation posture (§2.2): an
-  attacker-controlled code path reaching state that the posture
-  claimed to confine.
- Unauthorized external-surface access: a caller outside the
-  configured authorization set (allowlist, or OS-level equivalent
-  for local-IPC surfaces) dispatching work, receiving output, or
-  resolving approvals (§2.6).
- Credential exfiltration: leakage of operator credentials or
-  session authorization material to a destination outside the
-  trust envelope, via a mechanism that should have prevented it
-  (environment scrubbing bug, adapter logging, transport error
-  that flushes credentials to an upstream, etc.).
- Trust-model documentation violations: code behaving contrary to
-  what this policy, Hermes Agent's own documentation, or reasonable
-  operator expectations would predict — including cases where
-  Hermes Agent has documented a stance about how its output should
-  be rendered by a consuming layer (dashboard, gateway adapter,
-  file writer, shell) and a code path breaks that stance.
-
-### 3.2 Out of Scope
-
-"Out of scope" here means "not a security vulnerability under this
-policy." It does not mean "not worth reporting." Improvements to the
-in-process heuristics, hardening ideas, and UX fixes are welcome as
-regular issues or pull requests — the approval gate can always catch
-more patterns, redaction can always get smarter, adapter behavior
-can always be tightened. These items just don't go through the
-private-disclosure channel and don't receive advisories.
-
- **Bypasses of in-process heuristics (§2.4)** — approval-gate regex
-  bypasses, redaction bypasses, Skills Guard pattern bypasses, and
-  analogous reports against future heuristics. These components are
-  not boundaries; defeating them is not a vulnerability under this
-  policy.
- **Prompt injection per se.** Getting the LLM to emit unusual
-  output — via injected content, hallucination, training artifacts,
-  or any other cause — is not itself a vulnerability. "I achieved
-  prompt injection" without a chained §3.1 outcome is not an
-  actionable report under this policy.
- **Consequences of a chosen isolation posture.** Reports that a
-  code path operating within its posture's scope can do what that
-  posture permits are not vulnerabilities. Examples: shell or file
-  tools reaching host state under the local backend; code-execution
-  or MCP subprocesses reaching host state under terminal-backend
-  isolation that only sandboxes shell; reports whose preconditions
-  require pre-existing write access to operator-owned configuration
-  or credential files (those are already inside the trust envelope).
- **Documented break-glass settings.** Operator-selected trade-offs
-  that explicitly disable protections: `--insecure` and equivalent
-  flags on the dashboard or other components, disabled approvals,
-  local backend in production, development profiles that bypass
-  hermes-home security, and similar. Reports against those
-  configurations are not vulnerabilities — that's the flag's job.
- **Community-contributed skills and plugins.** Third-party skills
-  (including the community skills repository) and third-party
-  plugins are in the operator's review surface, not Hermes Agent's
-  trust surface (§2.4, §2.5). A skill or plugin doing something
-  malicious is the expected failure mode of one that wasn't
-  reviewed, not a vulnerability in Hermes Agent. Bugs in Hermes
-  Agent's skill-install or plugin-install path that prevent the
-  operator from seeing what they're installing are in scope under
-  §3.1.
- **Public exposure without external controls.** Exposing the
-  gateway or API to the public internet without authentication,
-  VPN, or firewall.
- **Tool-level read/write restrictions on a posture where shell is
-  permitted.** If a path is reachable via the terminal tool, reports
-  that other file tools can reach it add nothing.
+The following scenarios are **not** considered security breaches:
+- **Prompt Injection:** Unless it results in a concrete bypass of the approval system, toolset restrictions, or container sandbox.
+- **Public Exposure:** Deploying the gateway to the public internet without external authentication or network protection.
+- **Trusted State Access:** Reports that require pre-existing write access to `~/.hermes/`, `.env`, or `config.yaml` (these are operator-owned files).
+- **Default Behavior:** Host-level command execution when `terminal.backend` is set to `local` — this is the documented default, not a vulnerability.
+- **Configuration Trade-offs:** Intentional break-glass settings such as `approvals.mode: "off"` or `terminal.backend: local` in production.
+- **Tool-level read/access restrictions:** The agent has unrestricted shell access via the `terminal` tool by design. Reports that a specific tool (e.g., `read_file`) can access a resource are not vulnerabilities if the same access is available through `terminal`. Tool-level deny lists only constitute a meaningful security boundary when paired with equivalent restrictions on the terminal side (as with write operations, where `WRITE_DENIED_PATHS` is paired with the dangerous command approval system).

-## 4. Deployment Hardening
+## 4. Deployment Hardening & Best Practices

-The single most important hardening decision is matching isolation
-(§2.2) to the trust of the content the agent will ingest. Beyond
-that:
+### Filesystem & Network
+- **Production sandboxing:** Use container backends (`docker`, `modal`, `daytona`) instead of `local` for untrusted workloads.
+- **File permissions:** Run as non-root (the Docker image uses UID 10000); protect credentials with `chmod 600 ~/.hermes/.env` on local installs.
+- **Network exposure:** Do not expose the gateway or API server to the public internet without VPN, Tailscale, or firewall protection. SSRF protection is enabled by default across all gateway platform adapters (Telegram, Discord, Slack, Matrix, Mattermost, etc.) with redirect validation. Note: the local terminal backend does not apply SSRF filtering, as it operates within the trusted operator's environment.

- Run the agent as a non-root user. The supplied container image
-  does this by default.
- Keep credentials in the operator credential file with tight
-  permissions, never in the main config, never in version control.
-  Under OpenShell, use the Provider store rather than an on-disk
-  credential file.
- Do not expose the gateway or API to the public internet without
-  VPN, Tailscale, or firewall protection. Under OpenShell, use the
-  network policy layer to restrict egress.
- Configure a caller allowlist for every network-exposed adapter
-  you enable (§2.6).
- Review third-party skills and plugins before install (§2.4,
-  §2.5). For skills, this means reading the Python and scripts,
-  not just SKILL.md. Skills Guard reports and the install audit
-  log are the review surface.
- Hermes Agent includes supply-chain guards for MCP server
-  launches and for dependency / bundled-package changes in CI; see
-  `CONTRIBUTING.md` for specifics.
+### Skills & Supply Chain
+- **Skill installation:** Review Skills Guard reports (`tools/skills_guard.py`) before installing third-party skills. The audit log at `~/.hermes/skills/.hub/audit.log` tracks every install and removal.
+- **MCP safety:** OSV malware checking runs automatically for `npx`/`uvx` packages before MCP server processes are spawned.
+- **CI/CD:** GitHub Actions are pinned to full commit SHAs. The `supply-chain-audit.yml` workflow blocks PRs containing `.pth` files or suspicious `base64`+`exec` patterns.
+
+### Credential Storage
+- API keys and tokens belong exclusively in `~/.hermes/.env` — never in `config.yaml` or checked into version control.
+- The credential pool system (`agent/credential_pool.py`) handles key rotation and fallback. Credentials are resolved from environment variables, not stored in plaintext databases.

-"""CJK/wide-character-aware re-alignment of model-emitted markdown tables.
-
-Models pad markdown tables assuming each character occupies one terminal
-cell. CJK glyphs and most emoji render as two cells, so the model's
-spacing collapses into drift the moment a table reaches a real terminal —
-header pipes line up, every body row drifts right by N cells per CJK
-char.
-
-This module rebuilds row padding using ``wcwidth.wcswidth`` (display
-columns), preserving the table's pipes and dashes so it still reads as a
-plain-text table in ``strip`` / unrendered display modes. Standard Rich
-markdown rendering already aligns CJK correctly inside a wide enough
-panel; this helper is for the paths that print the model's text more or
-less verbatim.
-
-The helper is deliberately conservative:
-
-* Only contiguous ``| ... |`` blocks with a divider line are rewritten.
-* Anything that does not look like a table is passed through unchanged.
-* Single-line / mid-stream fragments are left alone — callers buffer
-  table rows and flush them once the block is complete.
-
-There is a small, intentional caveat: ``wcwidth`` returns ``-1`` for some
-emoji-with-variation-selector sequences (e.g. ``⚠️``); we clamp those to
-0 so they do not corrupt the column width math. The 1-cell drift on
-those specific glyphs is preferable to silently widening every table
-that contains one.

@@ -4,50 +4,18 @@ There are two ways to add a platform to the Hermes gateway:

 ## Plugin Path (Recommended for Community/Third-Party)

-Create a plugin directory in `~/.hermes/plugins/` (or under `plugins/platforms/`
-for bundled plugins) with a `plugin.yaml` and `adapter.py`.  The adapter
-inherits from `BasePlatformAdapter` and registers via
-`ctx.register_platform()` in the `register(ctx)` entry point.  This requires
-**zero changes to core Hermes code**.
+Create a plugin directory in `~/.hermes/plugins/` with a `PLUGIN.yaml` and
+`adapter.py`.  The adapter inherits from `BasePlatformAdapter` and registers
+via `ctx.register_platform()` in the `register(ctx)` entry point.  This
+requires **zero changes to core Hermes code**.

 The plugin system automatically handles: adapter creation, config parsing,
 user authorization, cron delivery, send_message routing, system prompt hints,
 status display, gateway setup, and more.

-**Optional hooks cover the edges most adapters need:**
-
- `env_enablement_fn: () -> Optional[dict]` — seeds `PlatformConfig.extra`
-  (and an optional `home_channel` dict) from env vars BEFORE the adapter is
-  constructed.  Without this, env-only setups don't surface in
-  `hermes gateway status` or `get_connected_platforms()` until the SDK
-  instantiates.
- `cron_deliver_env_var: str` — name of the `*_HOME_CHANNEL` env var.  When
-  set, `deliver=<name>` cron jobs route to this var without editing
-  `cron/scheduler.py`'s hardcoded sets.
- `standalone_sender_fn: async (...) -> dict`: out-of-process delivery
-  for cron jobs that run separately from the gateway.  Without this, a
-  `deliver=<name>` job fires correctly but the actual send returns
-  `No live adapter for platform '<name>'`.  Pair with `cron_deliver_env_var`
-  for end-to-end cron support.  See the docsite for the signature.
- `plugin.yaml` `requires_env` / `optional_env` rich-dict entries —
-  auto-populate `OPTIONAL_ENV_VARS` in `hermes_cli/config.py` so the setup
-  wizard surfaces proper descriptions, prompts, password flags, and URLs.
-
-**Subclassing for platform-specific UX.** When a platform has a hard
-time-window constraint that the base adapter can't anticipate (LINE's
-60s single-use reply token, WhatsApp's 24h session window, etc.), an
-adapter can override `_keep_typing` to layer a mid-flight bubble at a
-threshold without expanding the kwarg surface. Always
-`await super()._keep_typing(...)` so the typing heartbeat keeps running,
-and tear down your side task in `finally`. See `plugins/platforms/line/`
-for the full pattern (Template Buttons postback at 45s, `RequestCache`
-state machine, `interrupt_session_activity` override for `/stop`
-orphans) and the developer-guide page for the prose walkthrough.
-
-See `plugins/platforms/irc/`, `plugins/platforms/teams/`, and
-`plugins/platforms/google_chat/` for complete working examples, and

-"""QQ Bot chunked upload flow.
-
-The QQ v2 API caps inline base64 uploads (``file_data`` / ``url``) at ~10 MB.
-For files between 10 MB and ~100 MB we have to use the three-step chunked
-upload flow::
-
-    1. POST /v2/{users|groups}/{id}/upload_prepare
-       → returns upload_id, block_size, and an array of pre-signed COS part URLs.
-    2. For each part:
-         PUT the part bytes to its pre-signed COS URL,
-         then POST /v2/{users|groups}/{id}/upload_part_finish to acknowledge.
-    3. POST /v2/{users|groups}/{id}/files with {"upload_id": ...}
-       → returns the ``file_info`` token the caller uses in a RichMedia
-       message.
-
-Error-code semantics (from the QQ Bot v2 API spec):
-
- ``40093001`` — ``upload_part_finish`` retryable. Retry until the server-provided
-  ``retry_timeout`` elapses (or a local cap).
- ``40093002`` — daily cumulative upload quota exceeded. Not retryable; surface
-  as :class:`UploadDailyLimitExceededError` so the caller can build a
-  user-friendly reply.
-
-Exceptions:
-
- :class:`UploadDailyLimitExceededError` — daily quota hit (non-retryable).
- :class:`UploadFileTooLargeError` — file exceeds the platform per-file limit.
- :class:`RuntimeError` — generic upload failure (network, part PUT, complete).
-
-Ported from WideLee's qqbot-agent-sdk v1.2.2 (``media_loader.py::ChunkedUploader``)

-"""QQ Bot inline keyboards + approval / update-prompt senders.
-
-QQ Bot v2 supports attaching inline keyboards to outbound messages. When a
-user clicks a button, the platform dispatches an ``INTERACTION_CREATE``
-gateway event containing the button's ``data`` payload. The bot must ACK the
-interaction promptly via ``PUT /interactions/{id}`` or the user sees an
-error indicator on the button.
-
-This module provides:
-
- :class:`InlineKeyboard` + button dataclasses — serialized into the
-  ``keyboard`` field of the outbound message body.
- :func:`build_approval_keyboard` — 3-button ✅ once / ⭐ always / ❌ deny
-  keyboard for tool-approval flows.
- :func:`build_update_prompt_keyboard` — Yes/No keyboard for update confirms.
- :func:`parse_approval_button_data` / :func:`parse_update_prompt_button_data`
-  — decode the ``button_data`` payload from ``INTERACTION_CREATE``.
- :class:`ApprovalRequest` + :class:`ApprovalSender` — high-level helper that
-  builds an approval message with keyboard and posts it to a c2c / group chat.
-
-``button_data`` formats::
-
-    approve:<session_key>:<decision>      # decision = allow-once|allow-always|deny
-    update_prompt:<answer>                # answer = y|n
-
-Ported from WideLee's qqbot-agent-sdk v1.2.2 (``approval.py`` + ``dto.py``
-keyboard types). Authorship preserved via Co-authored-by.

-"""Per-platform slash command access control.
-
-This module sits beside the existing per-platform allowlist (``allow_from``)
-and adds a second axis: of the users who are *allowed to talk to the
-gateway*, which ones can run *which slash commands*.
-
-Two lists per platform scope (DM vs group, mirroring ``allow_from`` vs
-``group_allow_from``):
-
-  - ``allow_admin_from``      — user IDs that get every registered slash
-                                command (built-in + plugin-registered).
-  - ``user_allowed_commands`` — slash command names non-admin users may
-                                run. Empty / unset → non-admins get no
-                                slash commands.
-
-Backward compatibility:
-
-  If ``allow_admin_from`` is not set for a scope, slash command gating
-  is disabled entirely for that scope. Every allowed user can run every
-  slash command, exactly like before. This means existing installs are
-  unaffected until an operator opts in by listing at least one admin.
-
-The gate is applied at the slash command dispatch site in
-``gateway/run.py`` so it covers BOTH built-in and plugin-registered
