fix(moonshot): strip $ref siblings and collapse tuple items in tool schemas

Port from anomalyco/opencode#24730: Moonshot's JSON Schema validator rejects
two shapes that the rest of the JSON Schema ecosystem accepts:

1. $ref nodes with sibling keywords. Moonshot expands the reference before
   validation and then rejects the node if keys like `description`, `type`,
   or `default` appear alongside $ref. MCP-sourced tool schemas commonly
   put a `description` on $ref-typed properties so the model sees the
   field hint — which worked on every provider except Moonshot.

2. Tuple-style `items` arrays (positional element schemas). Moonshot's
   engine requires ONE schema applied to every array element. Common in
   tool schemas generated from Go/Protobuf that model fixed-length arrays
   as `[{type:number}, {type:number}]`.

Repairs applied in `agent/moonshot_schema.py`:

- Rule 3: when a node has `$ref`, return `{"$ref": <value>}` only
  (strip every sibling). The referenced definition still carries its own
  description on the target node, which Moonshot accepts.
- Rule 4: when `items` is a list, collapse to the first element schema
  (falling back to `{}` which is then filled by the generic missing-type
  rule). Preserves `minItems` / `maxItems` / other siblings.

Tests: 10 new cases across TestRefSiblingStripping + TestTupleItems,
plus the existing TestMissingTypeFilled::test_ref_node_is_not_given_synthetic_type
still passes (it asserted plain $ref passes through; now it passes through
as exactly `{"$ref": "..."}` which is strictly compatible).

All 35 tests in test_moonshot_schema.py pass.

-  # and queueing is cheap (move-main is a ~30s registry op).

-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.

-          **If you only changed pyproject.toml:** run `uv lock` locally

-
-### Skill authoring standards (HARDLINE)
-
-Every new or modernized skill — bundled, optional, or contributed —
-must meet these standards before merge. Reviewers reject PRs that
-violate them.
-
-1. **`description` ≤ 60 characters, one sentence, ends with a period.**
-   Long descriptions bloat skill listings and dilute the model's
-   attention when many skills are loaded. State the capability, not
-   the implementation. No marketing words ("powerful",
-   "comprehensive", "seamless", "advanced"). Don't repeat the skill
-   name. Verify with:
-   ```python
-   import re, pathlib
-   m = re.search(r'^description: (.*)$',
-                 pathlib.Path('skills/<cat>/<name>/SKILL.md').read_text(),
-                 re.MULTILINE)
-   assert len(m.group(1)) <= 60, len(m.group(1))
-   ```
-
-2. **Tools referenced in SKILL.md prose must be native Hermes tools or
-   MCP servers the skill explicitly expects.** When the skill needs a
-   capability, point at the proper tool by name in backticks
-   (`` `terminal` ``, `` `web_extract` ``, `` `read_file` ``,
-   `` `patch` ``, `` `search_files` ``, `` `vision_analyze` ``,
-   `` `browser_navigate` ``, `` `delegate_task` ``, etc.). Do NOT
-   name shell utilities the agent already has wrapped — `grep` →
-   `search_files`, `cat`/`head`/`tail` → `read_file`, `sed`/`awk` →
-   `patch`, `find`/`ls` → `search_files target='files'`. If the skill
-   depends on an MCP server, name the MCP server and document the
-   expected setup in `## Prerequisites`. Anything else (third-party
-   CLIs, shell pipelines, etc.) is fair game inside script files but
-   should not be the headline interaction surface in the prose.
-
-3. **`platforms:` gating audited against actual script imports.**
-   Skills that use POSIX-only primitives (`fcntl`, `termios`,
-   `os.setsid`, `os.kill(pid, 0)` for liveness, `/proc`, `/tmp`
-   hardcoded, `signal.SIGKILL`, bash heredocs, `osascript`, `apt`,
-   `systemctl`) must declare their supported platforms. Default
-   posture: try to fix it cross-platform first — `tempfile.gettempdir`,
-   `pathlib.Path`, `psutil.pid_exists`, Python-level filtering instead
-   of `grep`. Gate to a narrower set only when the dependency is
-   genuinely platform-bound.
-
-4. **`author` credits the human contributor first.** For external
-   contributions, the contributor's real name + GitHub handle goes
-   first; "Hermes Agent" is the secondary collaborator. If the
-   contributor's commit shows "Hermes Agent" as author (because they
-   used Hermes to draft the skill), replace it with their actual name
-   — credit the human, not the tool.
-
-5. **SKILL.md body uses the modern section order.** `# <Skill> Skill`
-   title, 2-3 sentence intro stating what it does and doesn't do,
-   `## When to Use`, `## Prerequisites`, `## How to Run`,
-   `## Quick Reference`, `## Procedure`, `## Pitfalls`,
-   `## Verification`. Target ~200 lines for a complex skill,
-   ~100 lines for a simple one. Cut redundant intro fluff, marketing
-   prose, and re-explanations of env vars already in
-   `## Prerequisites`.
-
-6. **Scripts go in `scripts/`, references in `references/`,
-   templates in `templates/`.** Don't expect the model to inline-write
-   parsers, XML walkers, or non-trivial logic every call — ship a
-   helper script. Reference it from SKILL.md by path relative to the
-   skill directory.
-
-7. **Tests live at `tests/skills/test_<skill>_skill.py`** and use only
-   stdlib + pytest + `unittest.mock`. No live network calls. Run via
-   `scripts/run_tests.sh tests/skills/test_<skill>_skill.py -q`.
-
-8. **`.env.example` additions are isolated to a clearly delimited
-   block.** Don't touch the surrounding file — contributor-supplied
-   `.env.example` versions are usually stale and edits outside the
-   skill's own block must be dropped during salvage.

-## Toolsets
-
-All toolsets are defined in `toolsets.py` as a single `TOOLSETS` dict.
-Each platform's adapter picks a base toolset (e.g. Telegram uses
-`"messaging"`); `_HERMES_CORE_TOOLS` is the default bundle most
-platforms inherit from.
-
-Current toolset keys: `browser`, `clarify`, `code_execution`, `cronjob`,
-`debugging`, `delegation`, `discord`, `discord_admin`, `feishu_doc`,
-`feishu_drive`, `file`, `homeassistant`, `image_gen`, `kanban`, `memory`,
-`messaging`, `moa`, `rl`, `safe`, `search`, `session_search`, `skills`,
-`spotify`, `terminal`, `todo`, `tts`, `video`, `vision`, `web`, `yuanbao`.
-
-Enable/disable per platform via `hermes tools` (the curses UI) or the
-`tools.<platform>.enabled` / `tools.<platform>.disabled` lists in
-`config.yaml`.
-
----
-
-## Delegation (`delegate_task`)
-
-`tools/delegate_tool.py` spawns a subagent with an isolated
-context + terminal session. Synchronous: the parent waits for the
-child's summary before continuing its own loop — if the parent is
-interrupted, the child is cancelled.
-
-Two shapes:
-
-- **Single:** pass `goal` (+ optional `context`, `toolsets`).
-- **Batch (parallel):** pass `tasks: [...]` — each gets its own subagent
-  running concurrently. Concurrency is capped by
-  `delegation.max_concurrent_children` (default 3).
-
-Roles:
-
-- `role="leaf"` (default) — focused worker. Cannot call `delegate_task`,
-  `clarify`, `memory`, `send_message`, `execute_code`.
-- `role="orchestrator"` — retains `delegate_task` so it can spawn its
-  own workers. Gated by `delegation.orchestrator_enabled` (default true)
-  and bounded by `delegation.max_spawn_depth` (default 2).
-
-Key config knobs (under `delegation:` in `config.yaml`):
-`max_concurrent_children`, `max_spawn_depth`, `child_timeout_seconds`,
-`orchestrator_enabled`, `subagent_auto_approve`, `inherit_mcp_toolsets`,
-`max_iterations`.
-
-Synchronicity rule: delegate_task is **not** durable. For long-running
-work that must outlive the current turn, use `cronjob` or
-`terminal(background=True, notify_on_complete=True)` instead.
-
----
-
-## Curator (skill lifecycle)
-
-Background skill-maintenance system that tracks usage on agent-created
-skills and auto-archives stale ones. Users never lose skills; archives
-go to `~/.hermes/skills/.archive/` and are restorable.
-
-- **Core:** `agent/curator.py` (review loop, auto-transitions, LLM review
-  prompt) + `agent/curator_backup.py` (pre-run tar.gz snapshots).
-- **CLI:** `hermes_cli/curator.py` wires `hermes curator <verb>` where
-  verbs are: `status`, `run`, `pause`, `resume`, `pin`, `unpin`,
-  `archive`, `restore`, `prune`, `backup`, `rollback`.
-- **Telemetry:** `tools/skill_usage.py` owns the sidecar
-  `~/.hermes/skills/.usage.json` — per-skill `use_count`, `view_count`,
-  `patch_count`, `last_activity_at`, `state` (active / stale /
-  archived), `pinned`.
-
-Invariants:
-- Curator only touches skills with `created_by: "agent"` provenance —
-  bundled + hub-installed skills are off-limits.
-- Never deletes; max destructive action is archive.
-- Pinned skills are exempt from every auto-transition and from the
-  LLM review pass.
-- `skill_manage(action="delete")` refuses pinned skills; patch/edit/
-  write_file/remove_file go through so the agent can keep improving
-  pinned skills.
-
-Config section (`curator:` in `config.yaml`):
-`enabled`, `interval_hours`, `min_idle_hours`, `stale_after_days`,
-`archive_after_days`, `backup.*`.
-
-Full user-facing docs: `website/docs/user-guide/features/curator.md`.

----
-
-## Cron (scheduled jobs)
-
-`cron/jobs.py` (job store) + `cron/scheduler.py` (tick loop). Agents
-schedule jobs via the `cronjob` tool; users via `hermes cron <verb>`
-(`list`, `add`, `edit`, `pause`, `resume`, `run`, `remove`) or the
-`/cron` slash command.
-
-Supported schedule formats:
-- Duration: `"30m"`, `"2h"`, `"1d"`
-- "every" phrase: `"every 2h"`, `"every monday 9am"`
-- 5-field cron expression: `"0 9 * * *"`
-- ISO timestamp (one-shot): `"2026-06-01T09:00:00Z"`
-
-Per-job fields include `skills` (load specific skills), `model` /
-`provider` overrides, `script` (pre-run data-collection script whose
-stdout is injected into the prompt; `no_agent=True` turns the script
-into the entire job), `context_from` (chain job A's last output into
-job B's prompt), `workdir` (run in a specific directory with its
-`AGENTS.md`/`CLAUDE.md` loaded), and multi-platform delivery.
-
-Hardening invariants:
-- **3-minute hard interrupt** on cron sessions — runaway agent loops
-  cannot monopolize the scheduler.
-- Catchup window: half the job's period, clamped to 120s–2h.
-- Grace window: 120s for one-shot jobs whose fire time was missed.
-- File lock at `~/.hermes/cron/.tick.lock` prevents duplicate ticks
-  across processes.
-- Cron sessions pass `skip_memory=True` by default; memory providers
-  intentionally do not run during cron.
-
-Cron deliveries are **not** mirrored into the target gateway session —
-they land in their own cron session with a header/footer frame so the
-main conversation's message-role alternation stays intact.
-
----
-
-## Kanban (multi-agent work queue)
-
-Durable SQLite-backed board that lets multiple profiles / workers
-collaborate on shared tasks. Users drive it via `hermes kanban <verb>`;
-workers spawned by the dispatcher drive it via a dedicated `kanban_*`
-toolset so their schema footprint is zero when they're not inside a
-kanban task.
-
-- **CLI:** `hermes_cli/kanban.py` wires `hermes kanban` with verbs
-  `init`, `create`, `list` (alias `ls`), `show`, `assign`, `link`,
-  `unlink`, `comment`, `complete`, `block`, `unblock`, `archive`,
-  `tail`, plus less-commonly-used `watch`, `stats`, `runs`, `log`,
-  `assignees`, `heartbeat`, `notify-*`, `dispatch`, `daemon`, `gc`.
-- **Worker toolset:** `tools/kanban_tools.py` exposes `kanban_show`,
-  `kanban_complete`, `kanban_block`, `kanban_heartbeat`, `kanban_comment`,
-  `kanban_create`, `kanban_link` — gated by `HERMES_KANBAN_TASK` so
-  the schema only appears for processes actually running as a worker.
-- **Dispatcher:** long-lived loop that (default every 60s) reclaims
-  stale claims, promotes ready tasks, atomically claims, and spawns
-  assigned profiles. Runs **inside the gateway** by default via
-  `kanban.dispatch_in_gateway: true`.
-- **Plugin assets:** `plugins/kanban/dashboard/` (web UI) +
-  `plugins/kanban/systemd/` (`hermes-kanban-dispatcher.service` for
-  standalone dispatcher deployment).
-
-Isolation model:
-- **Board** is the hard boundary — workers are spawned with
-  `HERMES_KANBAN_BOARD` pinned in their env so they can't see other
-  boards.
-- **Tenant** is a soft namespace *within* a board — one specialist
-  fleet can serve multiple businesses with workspace-path + memory-key
-  isolation.
-- After ~5 consecutive spawn failures on the same task the dispatcher
-  auto-blocks it to prevent spin loops.

-   If the skill depends on an MCP server, name the MCP server and document its setup in `## Prerequisites`. Third-party CLIs (e.g. `ffmpeg`, `gh`, a specific SDK) are fine to invoke from inside script files, but the prose should frame the interaction as "invoke through the `terminal` tool", not as a manual shell session.

+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.
-

-   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:

+   import platform
    if platform.system() != "Windows":

-   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.

-           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.
+5. **Shell commands in installers.** If you change `scripts/install.sh`, check if the equivalent change is needed in `scripts/install.ps1`.

-
-If you already have Git installed, the installer detects it and uses that instead.  Otherwise a ~45MB MinGit download is all you need — it won't touch or interfere with any system Git.

 > **Android / Termux:** The tested manual path is documented in the [Termux guide](https://hermes-agent.nousresearch.com/docs/getting-started/termux). On Termux, Hermes installs a curated `.[termux]` extra because the full `.[all]` extra currently pulls Android-incompatible voice dependencies.
 >
-> **Windows:** Native Windows is supported as an **early beta** — the PowerShell one-liner above installs everything, but expect rough edges and please file issues when you hit them. If you'd rather use WSL2 (our most battle-tested Windows path), the Linux command works there too. Native Windows install lives under `%LOCALAPPDATA%\hermes`; WSL2 installs under `~/.hermes` as on Linux.  The only Hermes feature that currently needs WSL2 specifically is the browser-based dashboard chat pane (it uses a POSIX PTY — classic CLI and gateway both run natively).

-## CLI 与消息平台 快速对照
-
-Hermes 有两种入口：用 `hermes` 启动终端 UI，或运行网关从 Telegram、Discord、Slack、WhatsApp、Signal 或 Email 与之对话。进入对话后，许多斜杠命令在两种界面中通用。
-
-| 操作 | CLI | 消息平台 |
-|------|-----|----------|
-| 开始对话 | `hermes` | 运行 `hermes gateway setup` + `hermes gateway start`，然后给机器人发消息 |
-| 开始新对话 | `/new` 或 `/reset` | `/new` 或 `/reset` |
-| 更换模型 | `/model [provider:model]` | `/model [provider:model]` |
-| 设置人格 | `/personality [name]` | `/personality [name]` |
-| 重试或撤销上一轮 | `/retry`、`/undo` | `/retry`、`/undo` |
-| 压缩上下文 / 查看用量 | `/compress`、`/usage`、`/insights [--days N]` | `/compress`、`/usage`、`/insights [days]` |
-| 浏览技能 | `/skills` 或 `/<skill-name>` | `/skills` 或 `/<skill-name>` |
-| 中断当前工作 | `Ctrl+C` 或发送新消息 | `/stop` 或发送新消息 |
-| 平台特定状态 | `/platforms` | `/status`、`/sethome` |
-
-完整命令列表请参阅 [CLI 指南](https://hermes-agent.nousresearch.com/docs/user-guide/cli) 和 [消息网关指南](https://hermes-agent.nousresearch.com/docs/user-guide/messaging)。

-## 从 OpenClaw 迁移
-
-如果你来自 OpenClaw，Hermes 可以自动导入你的设置、记忆、技能和 API 密钥。
-
-**首次安装时：** 安装向导（`hermes setup`）会自动检测 `~/.openclaw` 并在配置开始前提供迁移选项。
-
-**安装后任意时间：**
-
-```bash
-hermes claw migrate              # 交互式迁移（完整预设）
-hermes claw migrate --dry-run    # 预览将要迁移的内容
-hermes claw migrate --preset user-data   # 仅迁移用户数据，不含密钥
-hermes claw migrate --overwrite  # 覆盖已有冲突
-```
-
-导入内容：
-- **SOUL.md** — 人格文件
-- **记忆** — MEMORY.md 和 USER.md 条目
-- **技能** — 用户创建的技能 → `~/.hermes/skills/openclaw-imports/`
-- **命令白名单** — 审批模式
-- **消息设置** — 平台配置、允许用户、工作目录
-- **API 密钥** — 白名单中的密钥（Telegram、OpenRouter、OpenAI、Anthropic、ElevenLabs）
-- **TTS 资产** — 工作区音频文件
-- **工作区指令** — AGENTS.md（使用 `--workspace-target`）
-
-使用 `hermes claw migrate --help` 查看所有选项，或使用 `openclaw-migration` 技能进行交互式代理引导迁移（含干运行预览）。

-> 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.

-## ✨ Highlights
-
-- **Multi-agent Kanban — delegate to an AI team that actually finishes** — Spin up a durable board, drop tasks on it, and let multiple Hermes workers pick them up, hand off, and close them out. 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. ([#20495](https://github.com/NousResearch/hermes-agent/pull/20495), [#20497](https://github.com/NousResearch/hermes-agent/pull/20497), [#18071](https://github.com/NousResearch/hermes-agent/pull/18071), [#21077](https://github.com/NousResearch/hermes-agent/pull/21077), [#20473](https://github.com/NousResearch/hermes-agent/pull/20473))
-
-- **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.

-"""Curator snapshot + rollback.
-
-A pre-run snapshot of ``~/.hermes/skills/`` (excluding ``.curator_backups/``
-itself) is taken before any mutating curator pass. Snapshots are tar.gz
-files under ``~/.hermes/skills/.curator_backups/<utc-iso>/`` with a
-companion ``manifest.json`` describing the snapshot (reason, time, size,
-counted skill files). Rollback picks a snapshot, moves the current
-``skills/`` tree aside into another snapshot so even the rollback itself
-is undoable, then extracts the chosen snapshot into place.
-
-The snapshot does NOT include:
-  - ``.curator_backups/`` (would recurse)
-  - ``.hub/`` (hub-installed skills — managed by the hub, not us)
-
-It DOES include:
-  - all SKILL.md files + their directories (``scripts/``, ``references/``,
-    ``templates/``, ``assets/``)
-  - ``.usage.json`` (usage telemetry — needed to rehydrate state cleanly)
-  - ``.archive/`` (so rollback restores previously-archived skills too)
-  - ``.curator_state`` (so rolling back also restores the last-run-at
-    pointer — otherwise the curator would immediately re-fire on the next
-    tick)
-  - ``.bundled_manifest`` (so protection markers stay consistent)
-
-Alongside the skills tarball, each snapshot also captures a copy of
-``~/.hermes/cron/jobs.json`` as ``cron-jobs.json`` when it exists. Cron
-jobs reference skills by name in their ``skills``/``skill`` fields; the
-curator's consolidation pass rewrites those in place via
-``cron.jobs.rewrite_skill_refs()``. Without capturing the pre-run state,
-rolling back the skills tree would leave cron jobs pointing at the
-umbrella skills even though the narrow skills they were originally
-configured with have been restored. We store the whole jobs.json for
-fidelity but rollback only touches the ``skills``/``skill`` fields — the
-rest (schedule, next_run_at, enabled, prompt, etc.) is live state and
-we leave it alone.

-"""Lightweight internationalization (i18n) for Hermes static user-facing messages.
-
-Scope (thin slice, by design): only the highest-impact static strings shown
-to the user by Hermes itself -- approval prompts, a handful of gateway slash
-command replies, restart-drain notices.  Agent-generated output, log lines,
-error tracebacks, tool outputs, and slash-command descriptions all stay in
-English.
-
-Catalog files live under ``locales/<lang>.yaml`` at the repo root.  Each
-catalog is a flat dict keyed by dotted paths (e.g. ``approval.choose`` or
-``gateway.approval_expired``).  Missing keys fall back to English; if English
-is missing too, the key path itself is returned so a broken catalog never
-crashes the agent.
-
-Usage::
-
-    from agent.i18n import t
-    print(t("approval.choose_long"))                       # current lang
-    print(t("gateway.draining", count=3))                  # {count} formatted
-    print(t("approval.choose_long", lang="zh"))            # explicit override
-
-Language resolution order:
-    1. Explicit ``lang=`` argument passed to :func:`t`
-    2. ``HERMES_LANGUAGE`` environment variable (for tests / quick override)
-    3. ``display.language`` from config.yaml
-    4. ``"en"`` (baseline)
-
-Supported languages: en, zh, ja, de, es, fr, tr, uk.  Unknown values fall back to en.

-"""Async LSP client over stdin/stdout.
-
-One :class:`LSPClient` corresponds to one ``(language_server, workspace_root)``
-pair — exactly what OpenCode keys clients on, and the same shape Claude
-Code uses.  The client owns a child process, drives the JSON-RPC
-exchange, and exposes:
-
-- :meth:`open_file` / :meth:`change_file` — text document sync
-- :meth:`wait_for_diagnostics` — block until the server emits fresh
-  diagnostics for a specific file (or a timeout fires)
-- :meth:`diagnostics_for` — read the current per-file diagnostic store
-- :meth:`shutdown` — graceful close + SIGTERM/SIGKILL fallback
-
-The class is designed for async use from a single asyncio event loop.
-The :class:`agent.lsp.manager.LSPService` runs an event loop in a
-background thread so the synchronous file_operations layer can call
-into it via :func:`agent.lsp.manager.LSPService.touch_file`.
-
-Implementation notes:
-
-- Push diagnostics are stored per-URI in :attr:`_push_diagnostics` from
-  ``textDocument/publishDiagnostics`` notifications.  Pull diagnostics
-  go in :attr:`_pull_diagnostics`.  The merged view dedupes by content.
-
-- Whole-document sync.  Even when the server advertises incremental
-  sync, we send a single ``contentChanges`` entry replacing the
-  entire document.  Pretending to be incremental while sending a
-  full replacement is well-tolerated by every major server and saves
-  range bookkeeping.  See OpenCode's ``client.ts:584-659`` for the
-  same trick.
-
-- The "touch-file dance": every ``open_file`` call also fires a
-  ``workspace/didChangeWatchedFiles`` notification (CREATED on the
-  first open, CHANGED thereafter).  Some servers (clangd, eslint)
-  only re-scan when this notification fires, even though the LSP spec
-  doesn't strictly require it.
-
-- ``ContentModified`` (-32801) errors get retried with exponential
-  backoff up to 3 times.  This matches Claude Code's
-  ``LSPServerInstance.sendRequest``.

-log for "did LSP fire on that edit?" without drowning in noise.
-
-The level model:
-
-- ``DEBUG`` for steady-state events that have no novel signal:
-  ``clean``, ``feature off``, ``extension not mapped``, ``no project
-  root for already-announced file``, ``server unavailable for
-  already-announced binary``.  These never reach ``agent.log`` at the
-  default INFO threshold.
-
-- ``INFO`` for state transitions worth surfacing exactly once per
-  session: ``active for <root>`` the first time a (server_id,
-  workspace_root) client starts, ``no project root for <path>``
-  the first time we see that file.  Plus every diagnostic event
-  (those are inherently rare and per-edit, exactly what users grep
-  for).
-
-- ``WARNING`` for action-required failures: ``server unavailable``
-  (binary not on PATH) the first time per (server_id, binary),
-  ``no server configured`` once per language.  Per-call WARNING for
-  timeouts and unexpected bridge exceptions.
-
-The dedup is in-process module-level sets.  Each set grows at most by
-the number of distinct (server_id, root) and (server_id, binary)
-pairs touched in one Python process — bytes of memory in even an
-aggressive monorepo session.  Bounded LRU was rejected: evicting an

-"""Service-level orchestration for LSP clients.
-
-The :class:`LSPService` is the bridge between the synchronous
-file_operations layer and the async :class:`agent.lsp.client.LSPClient`.
-
-Design choices:
-
-- A **single asyncio event loop** runs in a background thread.  All
-  client work happens on that loop.  Synchronous callers from
-  ``tools/file_operations.py`` use :meth:`get_diagnostics_sync` to
-  open + wait + drain in one blocking call.
-
-- One client per ``(server_id, workspace_root)`` key.  Lazy spawn:
-  the first request for a key spawns the client; subsequent requests
-  re-use it.
-
-- A **broken-set** records ``(server_id, workspace_root)`` pairs that
-  failed to spawn or initialize.  These are never retried for the
-  life of the service.  Mirrors OpenCode's design.
-
-- A **delta baseline** map keeps "diagnostics-as-of-the-last-snapshot"
-  per file.  ``snapshot_baseline()`` is called BEFORE a write; the
-  next ``get_diagnostics_sync()`` returns only diagnostics that
-  weren't in the baseline.  This is the lift from Claude Code's
-  ``beforeFileEdited`` / ``getNewDiagnostics`` pattern, except wired
-  to the local LSP layer instead of MCP IDE RPC.
-
-The service is **off by default** — call :meth:`is_active` to check
-whether it's actually doing anything.  When LSP is disabled in
-config, when no git workspace can be detected, when all configured
-servers are missing binaries and auto-install is off, ``is_active``
-returns False and the file_operations layer falls through to the
-in-process syntax check.

-"""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.

-
-Every Hermes request that hits the Nous Portal — main agent loop, auxiliary
-client (compression / titles / vision / web_extract / session_search / etc.),
-and any future code path — must carry the same product-attribution tags so
-Nous can attribute usage to Hermes Agent and bucket it by client release.

-The version is sourced live from ``hermes_cli.__version__`` so it auto-aligns
-to whatever release is installed; the release script
-(``scripts/release.py``) regex-bumps that single string, and every Portal
-request picks up the new tag on the next process start.
-
-Why one helper instead of inlining the literal at each site:
-* Four call sites (main loop profile, aux client, run_agent compression
-  fallback, web_tools fallback) used to drift apart — see PR #24194 which
-  only got the aux site, leaving the main loop sending a different tag set.
-* Tests should assert the same tag list everywhere; centralizing makes that
-  assertion a one-liner against this module.
-
-Do NOT pre-compute these as module-level constants in the consumers. The

-"""Stateful scrubber for reasoning/thinking blocks in streamed assistant text.
-
-``run_agent._strip_think_blocks`` is regex-based and correct for a complete
-string, but when it runs *per-delta* in ``_fire_stream_delta`` it destroys
-the state that downstream consumers (CLI ``_stream_delta``, gateway
-``GatewayStreamConsumer._filter_and_accumulate``) rely on.
-
-Concretely, when MiniMax-M2.7 streams
-
-    delta1 = "<think>"
-    delta2 = "Let me check their config"
-    delta3 = "</think>"
-
-the per-delta regex erases delta1 entirely (case 2: unterminated-open at
-boundary matches ``^<think>...``), so the downstream state machine never
-sees the open tag, treats delta2 as regular content, and leaks reasoning
-to the user.  Consumers that don't run their own state machine (ACP,
-api_server, TTS) never had any defence at all — they just emitted
-whatever survived the upstream regex.
-
-This module centralises the tag-suppression state machine at the
-upstream layer so every stream_delta_callback sees text that has
-already had reasoning blocks removed.  Partial tags at delta
-boundaries are held back until the next delta resolves them, and
-end-of-stream flushing surfaces any held-back prose that turned out
-not to be a real tag.
-
-Usage::
-
-    scrubber = StreamingThinkScrubber()
-    for delta in stream:
-        visible = scrubber.feed(delta)
-        if visible:
-            emit(visible)
-    tail = scrubber.flush()  # at end of stream
-    if tail:
-        emit(tail)
-
-The scrubber is re-entrant per agent instance.  Call ``reset()`` at
-the top of each new turn so a hung block from an interrupted prior
-stream cannot taint the next turn's output.
-
-Tag variants handled (case-insensitive):
-  ``<think>``, ``<thinking>``, ``<reasoning>``, ``<thought>``,
-  ``<REASONING_SCRATCHPAD>``.
-
-Block-boundary rule for opens: an opening tag is only treated as a
-reasoning-block opener when it appears at the start of the stream,
-after a newline (optionally followed by whitespace), or when only
-whitespace has been emitted on the current line.  This prevents prose
-that *mentions* the tag name (e.g. ``"use <think> tags here"``) from
-being incorrectly suppressed.  Closed pairs (``<think>X</think>``) are
-always suppressed regardless of boundary; a closed pair is an
-intentional, bounded construct.

-"""Session adapter for codex app-server runtime.
-
-Owns one Codex thread per Hermes session. Drives `turn/start`, consumes
-streaming notifications via CodexEventProjector, handles server-initiated
-approval requests (apply_patch, exec command), translates cancellation,
-and returns a clean turn result that AIAgent.run_conversation() can splice
-into its `messages` list.
-
-Lifecycle:
-    session = CodexAppServerSession(cwd="/home/x/proj")
-    session.ensure_started()                              # spawns + handshake + thread/start
-    result = session.run_turn(user_input="hello")         # blocks until turn/completed
-    # result.final_text          → assistant text returned to caller
-    # result.projected_messages  → list of {role, content, ...} for messages list
-    # result.tool_iterations     → how many tool-shaped items completed (skill nudge counter)
-    # result.interrupted         → True if Ctrl+C / interrupt_requested fired mid-turn
-    session.close()                                       # tears down subprocess
-
-Threading model: the adapter is single-threaded from the caller's perspective.
-The underlying CodexAppServerClient owns its own reader threads but exposes
-blocking-with-timeout queues that this adapter polls in a loop, so the run_turn
-call is synchronous and behaves like AIAgent's existing chat_completions loop.

-"""Hermes-tools-as-MCP server for the codex_app_server runtime.
-
-When the user runs `openai/*` turns through the codex app-server, codex
-owns the loop and builds its own tool list. By default, that means
-Hermes' richer tool surface — web search, browser automation,
-delegate_task subagents, vision analysis, persistent memory, skills,
-cross-session search, image generation, TTS — is unreachable.
-
-This module exposes a curated subset of those Hermes tools to the
-spawned codex subprocess via stdio MCP. Codex registers it as a normal
-MCP server (per `~/.codex/config.toml [mcp_servers.hermes-tools]`) and
-the user gets full Hermes capability inside a Codex turn.
-
-Scope (what we expose):
-  - web_search, web_extract              — Firecrawl, no codex equivalent
-  - browser_navigate / _click / _type /  — Camofox/Browserbase automation
-    _snapshot / _screenshot / _scroll / _back / _press / _vision
-  - delegate_task                        — Hermes subagents
-  - vision_analyze                       — image inspection by vision model
-  - image_generate                       — image generation
-  - memory                               — Hermes' persistent memory store
-  - skill_view, skills_list              — Hermes' skill library
-  - session_search                       — cross-session search
-  - text_to_speech                       — TTS
-
-What we DO NOT expose (codex has equivalents):
-  - terminal / shell                     — codex's own shell tool
-  - read_file / write_file / patch       — codex's apply_patch + shell
-  - search_files / process               — codex's shell
-  - clarify, todo                        — codex's own UX
-
-Run with: python -m agent.transports.hermes_tools_mcp_server
-Spawned by: CodexAppServerSession.ensure_started() when the runtime is

-Video Generation Provider ABC
-=============================
-
-Defines the pluggable-backend interface for video generation. Providers register
-instances via ``PluginContext.register_video_gen_provider()``; the active one
-(selected via ``video_gen.provider`` in ``config.yaml``) services every
-``video_generate`` tool call.
-
-Providers live in ``<repo>/plugins/video_gen/<name>/`` (built-in, auto-loaded
-as ``kind: backend``) or ``~/.hermes/plugins/video_gen/<name>/`` (user, opt-in
-via ``plugins.enabled``).
-
-Mirrors the ``image_gen`` provider design (``agent/image_gen_provider.py``) so
-the two surfaces stay learnable together.
-
-Unified surface
----------------
-One tool — ``video_generate`` — covers **text-to-video** and **image-to-video**.
-The router is the presence of ``image_url``: if it's set, the provider routes
-to its image-to-video endpoint; if it's omitted, the provider routes to
-text-to-video. Users pick one **model family** (e.g. Pixverse v6, Veo 3.1,
-Kling O3 Standard); the provider handles which underlying FAL/xAI endpoint
-to hit.
-
-Video edit and video extend are intentionally NOT exposed in this surface —
-the inconsistency across backends is too large for one unified tool. If
-those use cases warrant attention later they can ship as separate tools.
-
-Response shape
---------------
-All providers return a dict built by :func:`success_response` /
-:func:`error_response`. Keys:
-
-    success         bool
-    video           str | None      URL or absolute file path
-    model           str             provider-specific model identifier
-    prompt          str             echoed prompt
-    modality        str             "text" | "image" (which mode was used)
-    aspect_ratio    str             provider-native (e.g. "16:9") or ""
-    duration        int             seconds (0 if not applicable)
-    provider        str             provider name (for diagnostics)
-    error           str             only when success=False
-    error_type      str             only when success=False

-Web Search Provider Registry
-============================
-
-Central map of registered web providers. Populated by plugins at import-time
-via :meth:`PluginContext.register_web_search_provider`; consumed by the
-``web_search`` and ``web_extract`` tool wrappers in :mod:`tools.web_tools` to
-dispatch each call to the active backend.
-
-Active selection
-----------------
-The active provider is chosen by configuration with this precedence:
-
-1. ``web.search_backend`` / ``web.extract_backend`` / ``web.crawl_backend``
-   (per-capability override).
-2. ``web.backend`` (shared fallback).
-3. If exactly one capability-eligible provider is registered AND available,
-   use it.
-4. Legacy preference order — ``firecrawl`` → ``parallel`` → ``tavily`` →
-   ``exa`` → ``searxng`` → ``brave-free`` → ``ddgs`` — filtered by
-   availability. Matches the historic ``tools.web_tools._get_backend()``
-   candidate order so installs that never set a config key keep landing
-   on the same provider they did before the plugin migration.
-5. Otherwise ``None`` — the tool surfaces a helpful error pointing at
-   ``hermes tools``.
-
-The capability filter (``supports_search`` / ``supports_extract`` /
-``supports_crawl``) is applied at every step so a search-only provider
-(``brave-free``) configured as ``web.extract_backend`` correctly falls
-through to an extract-capable backend.

-# Telegram DM User-Managed Multi-Session Topics Implementation Plan
-
-> **For Hermes:** Use test-driven-development for implementation. Use subagent-driven-development only after this plan is split into small reviewed tasks.
-
-**Goal:** Add an opt-in Telegram DM multi-session mode where Telegram user-created private-chat topics become independent Hermes session lanes, while the root DM becomes a system lobby.
-
-**Architecture:** Rely on Telegram's native private-chat topic UI. Users create new topics with the `+` button; Hermes maps each `message_thread_id` to a separate session lane. Hermes does not create topics for normal `/new` flow and does not try to manage topic lifecycle beyond activation/status, root-lobby behavior, and restoring legacy sessions into a user-created topic.
-
-**Tech Stack:** Hermes gateway, Telegram Bot API 9.4+, python-telegram-bot adapter, SQLite SessionDB / side tables, pytest.
-
----
-
-## 1. Product decisions
-
-### Accepted
-
-- PR-quality implementation: migrations, tests, docs, backwards compatibility.
-- Use SQLite persistence, not JSON sidecars.
-- Live status suffixes in topic titles are out of MVP.
-- Topic title sync/editing is out of MVP except future-compatible storage if cheap.
-- User creates Telegram topics manually through the Telegram bot interface.
-- `/new` does **not** create Telegram topics.
-- Root/main DM becomes a system lobby after activation.
-- Existing Telegram behavior remains unchanged until the feature is activated/enabled.
-- Migration of old sessions is supported through `/topic` listing and `/topic <session_id>` restore inside a user-created topic.
-
-### Telegram API assumptions verified from Bot API docs
-
-- `getMe` returns bot `User` fields:
-  - `has_topics_enabled`: forum/topic mode enabled in private chats.
-  - `allows_users_to_create_topics`: users may create/delete topics in private chats.
-- `createForumTopic` works for private chats with a user, but MVP does not rely on it for normal flow.
-- `Message.message_thread_id` identifies a topic in private chats.
-- `sendMessage` supports `message_thread_id` for private-chat topics.
-- `pinChatMessage` is allowed in private chats.
-

-
-## 2. Target UX
-
-### 2.1 Activation from root/main DM
-
-User sends:
-
-```text
-/topic
-```
-
-Hermes:
-
-1. calls Telegram `getMe`;
-2. verifies `has_topics_enabled` and `allows_users_to_create_topics`;
-3. enables multi-session topic mode for this Telegram DM user/chat;
-4. sends an onboarding message;
-5. pins the onboarding message if configured;
-6. shows old/unlinked sessions that can be restored into topics.
-
-Suggested onboarding text:
-
-```text
-Multi-session mode is enabled.
-
-Create new Hermes chats with the + button in this bot interface. Each Telegram topic is an independent Hermes session, so you can work on different tasks in parallel.
-
-This main chat is reserved for system commands, status, and session management.
-
-To restore an old session:
-1. Use /topic here to see unlinked sessions.
-2. Create a new topic with the + button.
-3. Send /topic <session_id> inside that topic.
-```
-
-### 2.2 Root/main DM after activation
-
-Root DM is a system lobby.
-
-Allowed/system commands include at least:
-
-- `/topic`
-- `/status`
-- `/sessions` if available
-- `/usage`
-- `/help`
-- `/platforms`
-
-Normal user prompts in root DM do not enter the agent loop. Reply:
-
-```text
-This main chat is reserved for system commands.
-
-To chat with Hermes, create a new topic using the + button in this bot interface. Each topic works as an independent Hermes session.
-```
-
-`/new` in root DM does not create a session/topic. Reply:
-
-```text
-To start a new parallel Hermes chat, create a new topic with the + button in this bot interface.
-
-Each topic is an independent Hermes session. Use /new inside a topic only if you want to replace that topic's current session.
-```
-
-### 2.3 First message in a user-created topic
-
-When a user creates a Telegram topic and sends the first message there:
-
-1. Hermes receives a Telegram DM message with `message_thread_id`.
-2. Hermes derives the existing thread-aware `session_key` from `(platform=telegram, chat_type=dm, chat_id, thread_id)`.
-3. If no binding exists, Hermes creates a fresh Hermes session for this topic lane and persists the binding.
-4. The message runs through the normal agent loop for that lane.
-
-### 2.4 `/new` inside a non-main topic
-
-`/new` remains supported but replaces the session attached to the current topic lane.
-
-Hermes should warn:
-
-```text
-Started a new Hermes session in this topic.
-
-Tip: for parallel work, create a new topic with the + button instead of using /new here. /new replaces the session attached to the current topic.
-```
-
-### 2.5 `/topic` in root/main DM after activation
-
-Shows:
-
-- mode enabled/disabled;
-- last capability check result;
-- whether intro message is pinned if known;
-- count of known topic bindings;
-- list of old/unlinked sessions.
-
-Example:
-
-```text
-Telegram multi-session topics are enabled.
-
-Create new Hermes chats with the + button in this bot interface.
-
-Unlinked previous sessions:
-1. 2026-05-01 Research notes — id: abc123
-2. 2026-04-30 Deploy debugging — id: def456
-3. Untitled session — id: ghi789
-
-To restore one:
-1. Create a new topic with the + button.
-2. Open that topic.
-3. Send /topic <id>
-```
-
-### 2.6 `/topic` inside a non-main topic
-
-Without args, show the current topic binding:
-
-```text
-This topic is linked to:
-Session: Research notes
-ID: abc123
-
-Use /new to replace this topic with a fresh session.
-For parallel work, create another topic with the + button.
-```
-
-### 2.7 `/topic <session_id>` inside a non-main topic
-
-Restore an old/unlinked session into the current user-created topic.
-
-Behavior:
-
-1. reject if not in Telegram DM topic;
-2. verify session belongs to the same Telegram user/chat or is a safe legacy root DM session for this user;
-3. reject if session is already linked to another active topic in MVP;
-4. `SessionStore.switch_session(current_topic_session_key, target_session_id)`;
-5. upsert binding with `managed_mode = restored`;
-6. send two messages into the topic:
-   - session restored confirmation;
-   - last Hermes assistant message if available.
-
-Example:
-
-```text
-Session restored: Research notes
-
-Last Hermes message:
-...
-```
-
----
-
-## 3. Persistence model
-
-Use SQLite, but topic-mode schema changes are **explicit opt-in migrations**, not automatic startup reconciliation.
-
-Important rollback-safety rule:
-
-- upgrading Hermes and starting the gateway must not create Telegram topic-mode tables or columns;
-- old/default Telegram behavior must keep working on the existing `state.db`;
-- the first `/topic` activation path calls an idempotent explicit migration, then enables topic mode for that chat;
-- if activation fails before the migration is needed, the database remains in the pre-topic-mode shape.
-
-### 3.1 No eager `sessions` table mutation for MVP
-
-Do **not** add `chat_id`, `chat_type`, `thread_id`, or `session_key` columns to `sessions` as part of ordinary `SessionDB()` startup. The existing declarative `_reconcile_columns()` mechanism would add them eagerly on every process start, which violates the managed-migration requirement.
-
-For MVP, keep origin/session-lane data in topic-specific side tables created only by the explicit `/topic` migration. Legacy unlinked sessions can be discovered conservatively from existing data (`source = telegram`, `user_id = current Telegram user`) plus absence from topic bindings.
-
-If future PRs need richer origin metadata for all gateway sessions, introduce it behind a separate explicit migration/command or a compatibility-reviewed schema bump.
-
-### 3.2 Explicit `/topic` migration API
-
-Add an idempotent method such as:
-
-```python
-def apply_telegram_topic_migration(self) -> None: ...
-```
-
-It creates only topic-mode side tables/indexes and records:
-
-```text
-state_meta.telegram_dm_topic_schema_version = 1
-```
-
-This method is called from `/topic` activation/status paths before reading or writing topic-mode state. It is not called from generic `SessionDB.__init__`, gateway startup, CLI startup, or auto-maintenance.
-
-### 3.3 `telegram_dm_topic_mode`
-
-Stores per-user/chat activation state. Created only by `apply_telegram_topic_migration()`.
-
-Suggested fields:
-
-- `chat_id` primary key
-- `user_id`
-- `enabled`
-- `activated_at`
-- `updated_at`
-- `has_topics_enabled`
-- `allows_users_to_create_topics`
-- `capability_checked_at`
-- `intro_message_id`
-- `pinned_message_id`
-
-### 3.4 `telegram_dm_topic_bindings`
-
-Stores Telegram topic/thread to Hermes session binding. Created only by `apply_telegram_topic_migration()`.
-
-Suggested fields:
-
-- `chat_id`
-- `thread_id`
-- `user_id`
-- `session_key`
-- `session_id`
-- `managed_mode`
-  - `auto`
-  - `restored`
-  - `new_replaced`
-- `linked_at`
-- `updated_at`
-
-Recommended constraints:
-
-- primary key `(chat_id, thread_id)`;
-- unique index on `session_id` for MVP to prevent one session linked to multiple topics;
-- index `(user_id, chat_id)` for status/listing.
-
-### 3.5 Unlinked session semantics
-
-For MVP, a session is unlinked if:
-
-- `source = telegram`;
-- `user_id = current Telegram user`;
-- no row in `telegram_dm_topic_bindings` has `session_id = session_id`.
-
-This is intentionally conservative until a future explicit migration adds richer cross-platform origin metadata.
-
-Never dedupe by title.

-
-## 4. Config
-
-Suggested config block:
-
-```yaml
-platforms:
-  telegram:
-    extra:
-      multisession_topics:
-        enabled: false
-        mode: user_managed_topics
-        root_chat_behavior: system_lobby
-        pin_intro_message: true
-```
-
-Notes:
-
-- `enabled: false` means existing Telegram behavior is unchanged.
-- Activation via `/topic` may create per-chat enabled state only if global config permits it.
-- `root_chat_behavior: system_lobby` is the MVP behavior for activated chats.
-
----
-
-## 5. Command behavior summary
-
-### `/topic` root/main DM
-
-- If not activated: capability check, activate, send/pin onboarding, list unlinked sessions.
-- If activated: show status and unlinked sessions.
-
-### `/topic` non-main topic
-
-- Show current binding.
-
-### `/topic <session_id>` root/main DM
-
-Reject with instructions:
-
-```text
-Create a new topic with the + button, open it, then send /topic <session_id> there to restore this session.
-```
-
-### `/topic <session_id>` non-main topic
-
-Restore that session into this topic if ownership/linking checks pass.
-
-### `/new` root/main DM when activated
-
-Reply with instructions to use the `+` button. Do not enter agent loop.
-
-### `/new` non-main topic
-
-Create a new session in the current topic lane, persist/update binding, warn that `+` is preferred for parallel work.
-
-### Normal text root/main DM when activated
-
-Reply with system-lobby instruction. Do not enter agent loop.
-
-### Normal text non-main topic
-
-Normal Hermes agent flow for that topic's session lane.

-
-## 6. PR breakdown
-
-### PR 1 — Explicit topic-mode schema migration
-
-**Goal:** Add rollback-safe SQLite support for Telegram topic mode without mutating `state.db` on ordinary upgrade/startup.
-
-**Files likely touched:**
-
-- `hermes_state.py`
-- tests under `tests/`
-
-**Tests first:**
-
-1. opening an old/current DB with `SessionDB()` does not create topic-mode tables or `sessions` origin columns;
-2. calling `apply_telegram_topic_migration()` creates `telegram_dm_topic_mode` and `telegram_dm_topic_bindings` idempotently;
-3. migration records `state_meta.telegram_dm_topic_schema_version = 1`.
-
-### PR 2 — Topic mode activation and binding APIs
-
-**Goal:** Add SQLite persistence for activation and topic bindings.
-
-**Tests first:**
-
-1. enable/check mode row round-trips;
-2. binding upsert and lookup by `(chat_id, user_id, thread_id)`;
-3. linked sessions are excluded from unlinked list.
-
-### PR 3 — `/topic` activation/status command
-
-**Goal:** Implement root activation/status/listing behavior.
-
-**Tests first:**
-
-1. `/topic` in root checks `getMe` capabilities and records activation;
-2. capability failure returns readable instructions;
-3. activated root `/topic` lists unlinked sessions.
-
-### PR 4 — System lobby behavior
-
-**Goal:** Prevent root chat from entering agent loop after activation.
-
-**Tests first:**
-
-1. normal text in activated root returns lobby instruction;
-2. `/new` in activated root returns `+` button instruction;
-3. non-activated root behavior is unchanged.
-
-### PR 5 — Auto-bind user-created topics
-
-**Goal:** First message in non-main topic creates/uses an independent session lane.
-
-**Tests first:**
-
-1. new topic message creates binding with `auto_created`;
-2. repeated topic message reuses same binding/lane;
-3. two topics in same DM do not share sessions.
-
-### PR 6 — Restore legacy sessions into a topic
-
-**Goal:** Implement `/topic <session_id>` in non-main topics.
-
-**Tests first:**
-
-1. root `/topic <id>` rejects with instructions;
-2. topic `/topic <id>` switches current topic lane to target session;
-3. restore rejects sessions from other users/chats;
-4. restore rejects already-linked sessions;
-5. restore emits confirmation and last Hermes assistant message.
-
-### PR 7 — `/new` inside topic updates binding
-
-**Goal:** Keep existing `/new` semantics but persist topic binding replacement.
-
-**Tests first:**
-
-1. `/new` in topic creates a new session for same topic lane;
-2. binding updates to `managed_mode = new_replaced`;
-3. response includes guidance to use `+` for parallel work.
-
-### PR 8 — Docs and polish
-
-**Goal:** Document the feature and Telegram setup.
-
-**Files likely touched:**
-
-- `website/docs/user-guide/messaging/telegram.md`
-- maybe `website/docs/user-guide/sessions.md`
-
-Docs must explain:
-
-- BotFather/Telegram settings for topic mode and user-created topics;
-- `/topic` activation;
-- root system lobby;
-- using `+` for new parallel chats;
-- restoring old sessions with `/topic <id>` inside a topic;
-- limitations.
-
----
-
-## 7. Testing / quality gates
-
-Run targeted tests after each TDD cycle, then broader tests before completion.
-
-Suggested commands after inspection confirms test paths:
-
-```bash
-python -m pytest tests/test_hermes_state.py -q
-python -m pytest tests/gateway/ -q
-python -m pytest tests/ -o 'addopts=' -q
-```
-
-Do not ship without verifying disabled-feature backwards compatibility.
-
