fix(cli): address Copilot review #1 (4 threads)

Thread 1 (cli.py:1488): Fix broken skin hook — class is SkinConfig
not Skin. The previous code silently no-op'd via the broad except,
so SkinConfig.get_color() calls weren't actually remapped. Verified
the hook fires now: in light mode, banner_text returns #1A1A1A
instead of #FFF8DC.

Thread 2 (cli.py:1328): Align comment with actual timeout. The OSC 11
read deadline is 100ms (time.monotonic() + 0.1), not 50ms. Fixed
the docstring.

Thread 3 (cli.py:13389): Remove unused imports of Point and Screen
in the _output_screen_diff monkey-patch block. Leftover from earlier
experiments — the wrapper only needs previous_screen mutation.

Thread 4 (cli.py:11422): Skip light-mode remap entirely when a pt
style string already specifies its own bg (e.g. 'bg:#1a1a2e #FFF8DC'
for status-bar / completion-menu). Those colors were tuned for that
specific dark bg; remapping the FG to #1A1A1A would produce
dark-on-dark (invisible). Now we detect the explicit 'bg:' token
and leave the whole value untouched.

Also dropped the stale comment block at the resize-handler that
described the old 'force \x1b[2J\x1b[H clear-screen on resize'
recovery — replaced with the actual current strategy
(monkey-patch _output_screen_diff).

-- Prefer small nanostores over component state when state is shared, reused, or read by distant UI.
-- Let each feature own its atoms. Chat state belongs near chat, shell state near shell, shared state in `src/store`.
-- Components that render from an atom should use `useStore`. Non-rendering actions should read with `$atom.get()`.
-- Do not pass state through three components when the leaf can subscribe to the atom.
-- Keep persistence beside the atom that owns it.
-- Keep route roots thin. They compose routes and shell; they should not become controllers.

-## Dependency Pinning Policy
-
-All dependencies must have upper bounds to limit supply-chain attack surface.
-This policy was established after the litellm compromise (PR #2796, #2810) and
-reinforced after the Mini Shai-Hulud worm campaign (May 2026).
-
-| Source type | Treatment | Example |
-|---|---|---|
-| PyPI package | `>=floor,<next_major` | `"httpx>=0.28.1,<1"` |
-| Git URL | Commit SHA | `git+https://...@<40-char-sha>` |
-| GitHub Actions | Commit SHA + comment | `uses: actions/checkout@<sha>  # v4` |
-| CI-only pip | `==exact` | `pyyaml==6.0.2` |
-
-**When adding a new dependency to `pyproject.toml`:**
-1. Pin to `>=current_version,<next_major` for post-1.0 (e.g. `>=1.5.0,<2`).
-2. For pre-1.0 packages, use `<0.(current_minor + 2)` (e.g. `>=0.29,<0.32`).
-3. Never commit a bare `>=X.Y.Z` without a ceiling — CI and reviewers will reject it.
-4. Run `uv lock` to regenerate `uv.lock` with hashes.

-  finishes in roughly the same wall time as before, but flake-free.
-- `isolate_timeout` (configured in `pyproject.toml`) caps each test at 30s.
-  Hangs are killed and surfaced as a failure report.
-- Pass `--no-isolate` to disable isolation — useful when debugging a single
-  test interactively, or when you specifically want to verify state leakage.
-- The plugin disables itself in child processes (sentinel envvar
-  `HERMES_ISOLATE_CHILD=1`), so there's no fork-bomb risk.

-### Dependency pinning policy (supply chain hardening)
-
-After the [litellm supply chain compromise](https://github.com/BerriAI/litellm/issues/24512) in March 2026 and the [Mini Shai-Hulud worm campaign](https://socket.dev/blog/tanstack-npm-packages-compromised-mini-shai-hulud-supply-chain-attack) in May 2026, all dependencies must follow these rules:
-
-| Source type | Required treatment | Rationale |
-|---|---|---|
-| **PyPI package** | `>=floor,<next_major` | PyPI versions are immutable once published, but new versions can be pushed into your range. A `<next_major` ceiling stops a 1.x install from upgrading to a malicious 2.0.0. |
-| **Git URL** (atroposlib, tinker, yc-bench, Baileys) | Full commit SHA | Branches and tags are mutable refs; SHA is content-addressed. |
-| **GitHub Actions** | Full commit SHA + version comment | Action tags are mutable refs (e.g. tj-actions/changed-files March 2025). Pin as `uses: owner/action@<sha>  # vX.Y.Z` |
-| **CI-only pip installs** | `==exact` | Hermetic CI builds; churn is acceptable. |
-
-**Every new PyPI dependency in a PR must have a `<next_major` upper bound.** PRs adding unbounded `>=X.Y.Z` specs will be rejected by reviewers. The `supply-chain-audit.yml` CI workflow also flags dependency manifest changes for manual review.
-
-**How to determine the ceiling:**
-- If the package is at version `1.x.y`, use `<2`.
-- If the package is at version `0.x.y` (pre-1.0), use `<0.(current_minor + 2)` — e.g. if current is `0.29.x`, use `<0.32`. This gives ~2 minor versions of headroom while keeping the window small enough that a hostile takeover version is unlikely to land inside it.
-- Exception: packages with very stable APIs (e.g. `aiohttp-socks`) can use `<1` at reviewer discretion.
-
-**Examples:**
-```toml
-# ✅ Correct — post-1.0
-"openai>=2.21.0,<3"
-"pydantic>=2.12.5,<3"
-
-# ✅ Correct — pre-1.0 (tight minor window)
-"asyncpg>=0.29,<0.32"
-"aiosqlite>=0.20,<0.23"
-"hindsight-client>=0.4.22,<0.5"
-
-# ❌ Rejected — no upper bound
-"some-package>=1.2.3"
-
-# ❌ Rejected — too tight (blocks legitimate patches)
-"some-package==1.2.3"
-
-# ❌ Rejected — too loose for pre-1.0 (allows 80 minor versions)
-"some-package>=0.20,<1"
-```
-
-**Reference PRs:** #2796 (litellm removal), #2810 (upper bounds pass), #9801 (SHA pinning + supply-chain-audit CI).

-## Skip the API-key collection — Nous Portal
-
-Hermes works with whatever provider you want — that's not changing. But if you'd rather not collect five separate API keys for the model, web search, image generation, TTS, and a cloud browser, **[Nous Portal](https://portal.nousresearch.com)** covers all of them under one subscription:
-
-- **300+ models** — pick any of them with `/model <name>`
-- **Tool Gateway** — web search (Firecrawl), image generation (FAL), text-to-speech (OpenAI), cloud browser (Browser Use), all routed through your sub. No extra accounts.
-
-One command from a fresh install:
-
-```bash
-hermes setup --portal
-```
-
-That logs you in via OAuth, sets Nous as your provider, and turns on the Tool Gateway. Check what's wired up any time with `hermes portal status`. Full details on the [Tool Gateway docs page](https://hermes-agent.nousresearch.com/docs/user-guide/features/tool-gateway).
-
-You can still bring your own keys per-tool whenever you want — the gateway is per-backend, not all-or-nothing.

 ## CLI vs Messaging Quick Reference

-## 省去到处收集 API Key — Nous Portal
-
-Hermes 始终允许你使用任意服务商，这点不会改变。但如果你不想为模型、网页搜索、图像生成、TTS、云浏览器分别去申请五个不同的 API Key，**[Nous Portal](https://portal.nousresearch.com)** 用一个订阅就能覆盖全部：
-
-- **300+ 模型** — 用 `/model <name>` 随时切换
-- **Tool Gateway** — 网页搜索（Firecrawl）、图像生成（FAL）、文本转语音（OpenAI）、云浏览器（Browser Use），全部通过订阅托管。无需额外注册任何账户。
-
-全新安装时一条命令即可：
-
-```bash
-hermes setup --portal
-```
-
-它会通过 OAuth 登录、把 Nous 设为推理服务商，并启用 Tool Gateway。随时用 `hermes portal status` 查看路由状态。完整说明见 [Tool Gateway 文档](https://hermes-agent.nousresearch.com/docs/user-guide/features/tool-gateway)。
-
-你随时可以按工具单独切回自己的 API Key — Gateway 是按工具粒度生效的，不是一刀切。

-> The Foundation Release — Hermes Agent installs and runs anywhere now. Native Windows ships in early beta with a full PowerShell installer story, a `pip install hermes-agent` wheel lands on PyPI, lazy-deps reshape what `pip install hermes-agent` actually pulls down, the supply-chain checker scans every install/upgrade for unsafe versions, and a new OpenAI-compatible local proxy lets Codex / Aider / Cline talk to OAuth-only providers (Claude Pro, ChatGPT Pro, SuperGrok). The cold-start wave shaves ~19 seconds off `hermes` launch, browser-tool CDP calls run 180x faster, and `hermes tools` All-Platforms drops from 14s to under 1.5s. Two new messaging platforms (LINE and SimpleX Chat) and a Microsoft Graph foundation (Teams pipeline + webhook adapter) land alongside `/handoff` that finally transfers sessions live, `vision_analyze` passing pixels through to vision-capable models, `x_search` as a first-class tool, LSP semantic diagnostics on every `write_file` / `patch`, a unified pluggable `video_generate`, a `computer_use` cua-driver backend, cross-session 1-hour Claude prompt caching, a per-turn file-mutation verifier, plus 9 new optional skills. 50+ P1 closures, 12 P0 closures.

-## ✨ Highlights
-
-- **Native Windows support (early beta)** — full PowerShell installer, native subprocess/PTY paths, taskkill-based process management, MinGit auto-install, Microsoft Store python stub detection, foreground Ctrl+C preservation, taskkill+ps2 fallback, npm prefix handling, and ~40 follow-up Windows-only fixes across CLI / gateway / TUI / curator / tools. Hermes finally runs natively on `cmd.exe` and PowerShell, no WSL required. ([#21561](https://github.com/NousResearch/hermes-agent/pull/21561), [#22130](https://github.com/NousResearch/hermes-agent/pull/22130), [#22752](https://github.com/NousResearch/hermes-agent/pull/22752), [#26618](https://github.com/NousResearch/hermes-agent/pull/26618), and many more)
-
-- **`pip install hermes-agent && hermes`** — Hermes Agent is now a real PyPI package. One command, no clone, no git, no shell installer. Wheel includes the Ink TUI bundle and shell launcher. (salvage of [#26350](https://github.com/NousResearch/hermes-agent/pull/26350)) ([#26593](https://github.com/NousResearch/hermes-agent/pull/26593))
-
-- **Cold-start performance wave — ~19s off `hermes` launch** — skills cache, lazy Feishu import, no Nous HTTP at startup, plus PEP-562 lazy adapter imports (QQ, Yuanbao, Teams, Google Chat), deferred `fal_client` / `google-cloud` / `httpx` loads, models.dev disk-cache-first lookup, parallel doctor API checks, eager-skip plugin discovery on built-in subcommands, `hermes tools` All-Platforms drops from 14s to <1.5s, welcome banner skipped on `chat -q`. ([#22138](https://github.com/NousResearch/hermes-agent/pull/22138), [#22120](https://github.com/NousResearch/hermes-agent/pull/22120), [#22681](https://github.com/NousResearch/hermes-agent/pull/22681), [#22790](https://github.com/NousResearch/hermes-agent/pull/22790), [#22808](https://github.com/NousResearch/hermes-agent/pull/22808), [#22831](https://github.com/NousResearch/hermes-agent/pull/22831), [#22859](https://github.com/NousResearch/hermes-agent/pull/22859), [#22904](https://github.com/NousResearch/hermes-agent/pull/22904), [#22766](https://github.com/NousResearch/hermes-agent/pull/22766), [#25341](https://github.com/NousResearch/hermes-agent/pull/25341))
-
-- **180x faster `browser_console` evaluations** — routed through the supervisor's persistent CDP WebSocket instead of spawning a fresh DevTools session per call. Real-world page interactions feel instant. ([#23226](https://github.com/NousResearch/hermes-agent/pull/23226))
-
-- **Supply-chain advisory checker + lazy-deps framework + tiered install fallback** — every `pip install` / `hermes update` scans dependencies against an advisory list, lazy-deps replace heavy import-time loads with first-use installs, and the installer falls back through extras tiers when a wheel rejects on the target platform. ([#24220](https://github.com/NousResearch/hermes-agent/pull/24220))
-
-- **OpenAI-compatible local proxy** — `hermes proxy` exposes any OAuth-authed provider (Claude Pro, ChatGPT Pro, SuperGrok) as an OpenAI-compatible endpoint that Codex / Aider / Cline / VS Code Continue can hit. Your subscription, your tools. ([#25969](https://github.com/NousResearch/hermes-agent/pull/25969))
-
-- **Cross-session 1-hour Claude prompt cache** — Anthropic / OpenRouter / Nous Portal now share a 1h prefix cache across sessions for Claude models. Fast resume, fast `/new`, lower cost on repeat work. ([#23828](https://github.com/NousResearch/hermes-agent/pull/23828))
-
-- **Two new messaging platforms — LINE + SimpleX Chat** — LINE Messaging API lands as a first-class platform, SimpleX Chat salvages #2558 onto the modern adapter spec. Hermes is now on 22 platforms. ([#23197](https://github.com/NousResearch/hermes-agent/pull/23197), [#26232](https://github.com/NousResearch/hermes-agent/pull/26232))
-
-- **Microsoft Graph foundation — Teams pipeline + webhook adapter** — `msgraph` auth/client foundation, webhook listener platform, Teams pipeline plugin runtime, and Teams outbound delivery via the existing adapter — Hermes can now read and post to Teams. (salvages of #21408–#21411) ([#21922](https://github.com/NousResearch/hermes-agent/pull/21922), [#21969](https://github.com/NousResearch/hermes-agent/pull/21969), [#22007](https://github.com/NousResearch/hermes-agent/pull/22007), [#22024](https://github.com/NousResearch/hermes-agent/pull/22024))
-
-- **`/handoff` actually transfers the session live** — the agent's active session moves to a different model / persona / profile mid-conversation, with messages, tool history, and context preserved. ([#23395](https://github.com/NousResearch/hermes-agent/pull/23395))
-
-- **`x_search` — first-class X (Twitter) search tool** — gated tool with OAuth-or-API-key auth, no skill needed to query the timeline. ([#26763](https://github.com/NousResearch/hermes-agent/pull/26763))
-
-- **`vision_analyze` returns pixels to vision-capable models** — when the active model can see, `vision_analyze` now hands the image straight through instead of falling back to a text description. ([#22955](https://github.com/NousResearch/hermes-agent/pull/22955))
-
-- **LSP semantic diagnostics on every write** — `write_file` and `patch` now run real language-server diagnostics on the post-edit file (delta-only) and surface real errors before they ship downstream. ([#24168](https://github.com/NousResearch/hermes-agent/pull/24168), [#25978](https://github.com/NousResearch/hermes-agent/pull/25978))
-
-- **Per-turn file-mutation verifier footer** — after every turn that wrote files, the agent gets a verifier footer summarizing what actually changed on disk — catches silent overwrites and "wrote it but it didn't land" bugs. ([#24498](https://github.com/NousResearch/hermes-agent/pull/24498))
-
-- **Unified `video_generate` with pluggable provider backends** — single tool, any backend. Drop in a new video provider as a plugin, no core changes. ([#25126](https://github.com/NousResearch/hermes-agent/pull/25126))
-
-- **`computer_use` cua-driver backend** — proper focus-safe ops, non-Anthropic provider support, refresh on `hermes update`. Computer-use is no longer locked to a single SDK. (re-salvage of #16936) ([#21967](https://github.com/NousResearch/hermes-agent/pull/21967), [#24063](https://github.com/NousResearch/hermes-agent/pull/24063))
-
-- **xAI Grok OAuth provider — SuperGrok via subscription** — sign in with your xAI account, talk to Grok models from Hermes. ([#26534](https://github.com/NousResearch/hermes-agent/pull/26534))
-
-- **Clarify with buttons — native inline keyboards on Telegram + Discord** — the `clarify` tool renders multi-choice prompts as platform-native buttons instead of typed responses. ([#24199](https://github.com/NousResearch/hermes-agent/pull/24199), [#25485](https://github.com/NousResearch/hermes-agent/pull/25485))
-
-- **Discord channel history backfill (default on)** — Hermes reads recent channel history when joining a thread so it actually knows what's been said. ([#25984](https://github.com/NousResearch/hermes-agent/pull/25984))
-
-- **Watchers skill — RSS / HTTP JSON / GitHub polling via cron `no_agent` mode** — skill recipes that wire change-detection sources directly into cron's script-only watchdog mode. ([#21881](https://github.com/NousResearch/hermes-agent/pull/21881))
-
-- **Zed ACP Registry integration + uvx distribution** — Hermes is in the Zed registry, installable via `uvx` (no npm). Plus `hermes acp --setup-browser` bootstraps browser tools for registry installs. (salvage of [#25908](https://github.com/NousResearch/hermes-agent/pull/25908)) ([#26079](https://github.com/NousResearch/hermes-agent/pull/26079), [#26120](https://github.com/NousResearch/hermes-agent/pull/26120), [#26234](https://github.com/NousResearch/hermes-agent/pull/26234))

-
-- **9 new optional skills** — Hyperliquid (perp/spot trading via SDK + REST) (@kshitijk4poor & Hermes), Yahoo Finance market data, api-testing (REST/GraphQL debug), unified EVM multi-chain skill (folds #25291 + #2010 + base/), darwinian-evolver, osint-investigation (closes #355), pinggy-tunnel, watchers (RSS/HTTP/GitHub via cron), Notion overhaul for the Developer Platform (May 2026).

-

-"""Microsoft Entra ID adapter for Microsoft Foundry.
-
-Provides keyless authentication for Microsoft Foundry deployments using the
-`azure-identity` SDK's `DefaultAzureCredential` chain (env service principal
-→ workload identity → managed identity → VS Code → Azure CLI → azd →
-PowerShell → broker).
-
-Architecture mirrors `agent/bedrock_adapter.py`:
-
-* Lazy import. `azure-identity` is only loaded when ``model.auth_mode =
-  entra_id`` is selected. Users who stick with `AZURE_FOUNDRY_API_KEY`
-  never pay the import cost.
-* SDK-callable contract. The public entry point ``build_token_provider``
-  returns a zero-arg callable produced by ``get_bearer_token_provider`` —
-  this is exactly the value Microsoft's documented sample plugs into
-  ``OpenAI(api_key=token_provider, base_url=...)``. The OpenAI SDK calls
-  it before every request, so token refresh is transparent.
-* Three explicit consumer-side helpers (display / cache / http-bearer)
-  rather than one generic "materialize" function — splitting them by
-  purpose prevents accidental token-minting in logging paths or token
-  leakage into cache keys / dashboard JSON.
-* No persisted JWT. ``azure-identity`` caches in-process and (where
-  available) in the OS keychain or ``~/.IdentityService``. Hermes does
-  not duplicate that storage in ``auth.json``.
-
-Reference: https://learn.microsoft.com/azure/ai-foundry/foundry-models/how-to/configure-entra-id

-    "If no loaded skill fits but an existing class-level skill does, "

-    "  3. ADD A SUPPORT FILE under an existing umbrella. Skills can be "

-    "directory per kind:\n"
-    "     • `references/<topic>.md` — session-specific detail (error "

-    "condensed knowledge banks: quoted research, API docs, external "
-    "authoritative excerpts, or domain notes you found while working "
-    "on the problem. Write it concise and for the value of the task, "
-    "not as a full mirror of upstream docs.\n"
-    "     • `templates/<name>.<ext>` — starter files meant to be "
-    "copied and modified (boilerplate configs, scaffolding, a "
-    "known-good example the agent can `reproduce with modifications`).\n"
-    "     • `scripts/<name>.<ext>` — statically re-runnable actions "
-    "the skill can invoke directly (verification scripts, fixture "
-    "generators, deterministic probes, anything the agent should run "
-    "rather than hand-type each time).\n"
-    "     Add support files via skill_manage action=write_file with "
-    "file_path starting 'references/', 'templates/', or 'scripts/'. "
-    "The umbrella's SKILL.md should gain a one-line pointer to any "
-    "new support file so future agents know it exists.\n"
-    "  4. CREATE A NEW CLASS-LEVEL UMBRELLA SKILL when no existing "
-    "skill covers the class. The name MUST be at the class level. "
-    "The name MUST NOT be a specific PR number, error string, feature "
-    "codename, library-alone name, or 'fix-X / debug-Y / audit-Z-today' "

-Browser Provider ABC
-====================
-
-Defines the pluggable-backend interface for cloud browser providers
-(Browserbase, Browser Use, Firecrawl, …). Providers register instances via
-:meth:`PluginContext.register_browser_provider`; the active one (selected via
-``browser.cloud_provider`` in ``config.yaml``) services every cloud-mode
-``browser_*`` tool call.
-
-Providers live in ``<repo>/plugins/browser/<name>/`` (built-in, auto-loaded as
-``kind: backend``) or ``~/.hermes/plugins/browser/<name>/`` (user, opt-in via
-``plugins.enabled``).
-
-This ABC mirrors :class:`agent.web_search_provider.WebSearchProvider` (PR
-#25182) — same shape, same registration flow, same picker integration. The
-legacy in-tree ``tools.browser_providers.base.CloudBrowserProvider`` ABC was
-deleted in PR #25214 (this work) along with the per-vendor inline modules in
-``tools/browser_providers/``; the lifecycle contract documented below is
-preserved bit-for-bit so the tool wrapper (:mod:`tools.browser_tool`) does
-not have to translate.
-
-Session metadata contract (preserved from the legacy ``CloudBrowserProvider``)::
-
-    {
-        "session_name": str,        # unique name for agent-browser --session
-        "bb_session_id": str,       # provider session ID (for close/cleanup)
-        "cdp_url": str,             # CDP websocket URL
-        "features": dict,           # feature flags that were enabled
-        "external_call_id": str,    # optional, managed-gateway billing key
-    }
-
-``bb_session_id`` is a legacy key name kept verbatim for backward compat with
-:mod:`tools.browser_tool` — it holds the provider's session ID regardless of
-which provider is in use.

-Browser Provider Registry
-=========================
-
-Central map of registered cloud browser providers. Populated by plugins at
-import-time via :meth:`PluginContext.register_browser_provider`; consumed by
-:func:`tools.browser_tool._get_cloud_provider` to route each cloud-mode
-``browser_*`` tool call to the active backend.
-
-Active selection
-----------------
-The active provider is chosen by configuration with this precedence:
-
-1. ``browser.cloud_provider`` in ``config.yaml`` (explicit override).
-2. Legacy preference order — ``browser-use`` → ``browserbase`` — filtered by
-   availability. Matches the historic auto-detect order in
-   :func:`tools.browser_tool._get_cloud_provider` (Browser Use checked first
-   because it covers both the managed Nous gateway and direct API key path;
-   Browserbase as the older direct-credentials fallback). ``firecrawl`` is
-   intentionally NOT in the legacy walk — users only get Firecrawl as a
-   cloud browser when they explicitly set ``browser.cloud_provider:
-   firecrawl``, matching pre-migration behaviour where Firecrawl was never
-   auto-selected.
-3. Otherwise ``None`` — the dispatcher falls back to local browser mode.
-
-The explicit-config branch (rule 1) intentionally ignores ``is_available()``
-so the dispatcher surfaces a typed "X_API_KEY is not set" error to the user
-instead of silently switching backends. Matches the legacy
-:func:`tools.browser_tool._get_cloud_provider` behaviour for configured names.
-
-Note: there is no "capability" split here (unlike the web subsystem, which
-has search/extract/crawl). Every browser provider implements the full
-:class:`agent.browser_provider.BrowserProvider` lifecycle; the registry's
-job is purely selection, not capability routing.

-# Event-driven Responses streaming
-#
-# OpenAI ships its consumer Codex backend (chatgpt.com/backend-api/codex) on
-# a different schedule from the openai Python SDK.  The high-level
-# ``client.responses.stream(...)`` helper reconstructs a typed Response from
-# the terminal ``response.completed`` event's ``response.output`` field, and
-# when that field drifts to ``null`` (gpt-5.5, May 2026) the SDK raises
-# ``TypeError: 'NoneType' object is not iterable`` mid-iteration.
-#
-# We sidestep the whole class of failure by going one level lower:
-# ``client.responses.create(stream=True)`` returns the raw AsyncIterable of
-# SSE events, and we assemble the final response object purely from
-# ``response.output_item.done`` events as they arrive.  We never read
-# ``response.completed.response.output`` for content reconstruction, so the
-# backend can return ``null``, ``[]``, a string, or omit the field entirely
-# and we don't care.
-#
-# This mirrors what the OpenClaw TS implementation does for the same backend
-# and is structurally immune to the bug class rather than patched.

-"""Context compression — extract the AIAgent methods that drive summarisation.

-Three concerns live here:
-
-* :func:`check_compression_model_feasibility` — startup probe of the
-  configured auxiliary compression model.  Warns when the aux context
-  window can't fit the main model's compression threshold; auto-lowers
-  the session threshold when possible; hard-rejects auxes below
-  ``MINIMUM_CONTEXT_LENGTH``.
-
-* :func:`replay_compression_warning` — re-emit a stored warning through
-  the gateway ``status_callback`` once it's wired up (the callback is
-  set after :class:`AIAgent` construction).
-
-* :func:`compress_context` — the actual compression call.  Runs the
-  configured compressor, splits the SQLite session, rotates the
-  session_id, notifies plugin context engines / memory providers, and
-  returns the compressed message list and freshly-built system prompt.
-
-* :func:`try_shrink_image_parts_in_messages` — image-too-large recovery
-  helper that re-encodes ``data:image/...;base64,...`` parts at a smaller
-  size so retries can fit under provider ceilings (Anthropic's 5 MB).
-
-``run_agent`` keeps thin wrappers for each so existing call sites
-(``self._compress_context(...)``) keep working.  Tests that exercise
-these paths see no behavioural change.

-        carrier.
-      * Credential / secret stores under HERMES_HOME and the global Hermes
-        root: ``auth.json``, ``auth.lock``, ``.anthropic_oauth.json``,
-        ``.env``, ``webhook_subscriptions.json``, ``auth/google_oauth.json``,
-        and anything under ``mcp-tokens/``. These hold plaintext provider keys,
-        OAuth tokens, and HMAC secrets that the agent never needs to read
-        directly — provider tools / gateway adapters consume them through
-        internal channels.
-      * Project-local environment files anywhere on disk: ``.env``,
-        ``.env.local``, ``.env.development``, ``.env.production``,
-        ``.env.test``, ``.env.staging``, ``.envrc``. These routinely hold
-        API keys, database passwords, and other credentials for the user's
-        own projects. The agent helping debug a project shouldn't normally
-        need to read these — ``.env.example`` is the documented-shape
-        substitute.
-
-    **This is NOT a security boundary.** The terminal tool runs as the
-    same OS user with shell access; the agent can still ``cat auth.json``
-    or ``cat ~/.hermes/.env`` and exfiltrate the file. The read-deny exists
-    as defense-in-depth that:
-
-      * Returns a clear error to models that respect tool denials, which
-        empirically prompts most modern models to stop rather than reach
-        for the shell.
-      * Surfaces a visible audit trail when something tries to read
-        credentials — easier to spot in logs than a generic ``cat``.
-
-    Treat any user-visible framing around this as "may help" rather than
-    "stops attackers." A determined model or malicious instruction can
-    always shell out.
-
-    Callers that resolve relative paths against a non-process cwd
-    (e.g. ``TERMINAL_CWD`` in ``tools/file_tools.py``) MUST pre-resolve
-    and pass the absolute path string.  This function's own ``resolve()``
-    is anchored at the Python process cwd, so a relative input like
-    ``"auth.json"`` would otherwise miss the denylist when the task's
-    terminal cwd differs from the process cwd.

-"""Diff-aware line-shift map for cross-edit LSP delta filtering.
-
-When an edit deletes or inserts lines in the middle of a file, every
-diagnostic below the edit point shifts to a new line number.  The
-LSPService delta filter subtracts the pre-edit baseline from the
-post-edit diagnostics keyed on ``(severity, code, source, message,
-range)`` — without an adjustment, the shifted-but-otherwise-identical
-diagnostics look brand-new and the agent gets flooded with noise.
-
-The fix used here is the same trick git's blame and unified diff use:
-build a piecewise-linear map from pre-edit line numbers to post-edit
-line numbers, then apply that map to baseline diagnostics before the
-set-difference.  Diagnostics whose pre-edit line is in a region the
-edit deleted return ``None`` and are dropped from the baseline (they
-genuinely no longer apply).
-
-Trade-off vs. dropping range from the key entirely (the previous
-fix): preserves the "new instance of an identical error at a
-different line" signal — if the model introduces a second instance
-of the same error class at a different location, that one will be
-surfaced as new instead of swallowed by content-only dedup.
-
-The map is derived from ``difflib.SequenceMatcher.get_opcodes()`` and

-
-Hermes pulls API keys from Bitwarden Secrets Manager at process startup
-so they don't have to live in plaintext in ``~/.hermes/.env``.
-
-Design summary
---------------
-
-* The ``bws`` binary is auto-installed into ``<hermes_home>/bin/bws`` on
-  first use.  Hermes pins one version (``_BWS_VERSION``) and downloads
-  the matching asset from the official GitHub Releases page, verifying
-  the SHA-256 against the release's published checksum file.
-* The access token is stored in ``~/.hermes/.env`` as
-  ``BWS_ACCESS_TOKEN`` (or whatever name the user picked in
-  ``secrets.bitwarden.access_token_env``).  This is the one
-  bootstrap secret — every other provider key can live in Bitwarden.
-* Pulling secrets is a single ``bws secret list <project_id>
-  --output json`` call.  We cache the result in-process for
-  ``cache_ttl_seconds`` so back-to-back ``hermes`` invocations don't
-  hammer the API.
-* Failures NEVER block Hermes startup.  Missing binary, no network,
-  expired token, etc. all emit a one-line warning and continue with
-  whatever credentials ``.env`` already had.
-
-The module is intentionally subprocess-driven rather than going through
-the ``bitwarden-sdk-secrets`` Python package: one cross-platform binary
-is easier to lazy-install than a wheels-with-Rust-extension dependency.

-"""Skill bundles — aliases that load multiple skills under one slash command.
-
-A skill bundle is a small YAML file that names a set of skills to load
-together. Invoking ``/<bundle-name>`` from the CLI or gateway loads every
-referenced skill's full content into a single user message, the same way
-``/<skill-name>`` does — but for N skills at once.
-
-Storage
--------
-Bundles live in ``~/.hermes/skill-bundles/*.yaml`` (and the equivalent
-profile-aware directory under ``HERMES_HOME``). Each file looks like::
-
-    name: backend-dev
-    description: Backend feature work — code review, testing, PR workflow.
-    skills:
-      - github-code-review
-      - test-driven-development
-      - github-pr-workflow
-    instruction: |
-      Optional extra guidance to inject above the skill bodies.
-
-The file's stem is treated as a fallback name when ``name:`` is absent, so
-dropping a YAML into the directory is enough to register a new bundle.
-
-Conflict resolution
--------------------
-If a bundle and a skill share the same slash name, the bundle wins. The
-slash command dispatch checks bundles first, then falls back to skills.
-This is the intended behavior — a user who names a bundle ``research``
-explicitly wants ``/research`` to mean their bundle, not whatever skill
-happens to share the slug.
-
-Public API
-----------
-- :func:`get_skill_bundles` — return ``{"/slug": bundle_info}``
-- :func:`resolve_bundle_command_key` — map a user-typed command to its slug
-- :func:`build_bundle_invocation_message` — produce the full user message
-- :func:`reload_bundles` — re-scan disk and return a diff
-- :func:`list_bundles` — return rich info for display (``hermes bundles``)
-- :func:`save_bundle` / :func:`delete_bundle` — file-level operations

-* ``_should_parallelize_tool_batch`` / ``_extract_parallel_scope_path`` /

-* ``_trajectory_normalize_msg`` — strip image blobs from a message for

-Transcription Provider ABC
-==========================
-
-Defines the pluggable-backend interface for speech-to-text. Providers
-register instances via
-:meth:`PluginContext.register_transcription_provider`; the active one
-(selected via ``stt.provider`` in ``config.yaml``) services every
-:func:`tools.transcription_tools.transcribe_audio` call **when the
-configured name is neither a built-in (``local``, ``local_command``,
-``groq``, ``openai``, ``mistral``, ``xai``) nor disabled**.
-
-Two coexisting STT extension surfaces — in resolution order:
-
-1. **Built-in providers** (``BUILTIN_STT_PROVIDERS`` in
-   :mod:`tools.transcription_tools`) — native Python implementations
-   for the 6 backends shipped today (faster-whisper, local_command,
-   Groq, OpenAI, Mistral, xAI). **Always win** — plugins cannot
-   shadow them. The single-env-var shell escape hatch
-   ``HERMES_LOCAL_STT_COMMAND`` is preserved via the built-in
-   ``local_command`` path.
-2. **Plugin-registered providers** (this ABC). For new STT backends —
-   OpenRouter, SenseAudio, Gemini-STT, custom proprietary engines —
-   that need a Python implementation without modifying
-   ``tools/transcription_tools.py``.
-
-Built-ins-always-win is enforced at registration time
-(:func:`agent.transcription_registry.register_provider` rejects names
-in ``BUILTIN_STT_PROVIDERS`` with a warning) AND at dispatch time
-(:func:`tools.transcription_tools._dispatch_to_plugin_provider`
-re-checks defensively).
-
-Providers live in ``<repo>/plugins/transcription/<name>/`` (built-in
-plugins, none shipped today) or
-``~/.hermes/plugins/transcription/<name>/`` (user-installed).
-
-Response contract
------------------

-
-    success      bool
-    transcript   str       transcribed text (empty when success=False)
