603a68b918 fix(acp): isolate per-session approval callback via ContextVar
Concurrent ACP sessions in one Hermes process previously shared
tools.terminal_tool._approval_callback as a module-global, so session B
overwriting the slot could route session A's dangerous-command prompt
through B's callback (and vice versa). Within a single OS user this was
UX confusion rather than a cross-principal boundary break, but the
shared state is genuine concurrency sloppiness worth fixing.

Store the callback (and the sibling sudo password callback) in
ContextVars. Each asyncio task gets its own copy, so per-session
set_approval_callback calls no longer stomp on each other. ACP's prompt
handler now wraps loop.run_in_executor in contextvars.copy_context().run
so the per-session callback survives the hop into the worker thread —
asyncio does not propagate contextvars across the executor boundary on
its own, and this was verified empirically.

Regression tests reproduce the original primitive (two overlapping
sessions, each asserts it observes its own callback) and document the
run_in_executor contextvar contract the ACP fix relies on.

Reported by @xeloxa in GHSA-qg5c-hvr5-hjgr.

# Security-update PRs for source dependencies (opened ONLY when a CVE is
# published affecting a currently-pinned version) are enabled separately

# (Settings → Code security → Dependabot → Dependabot security updates).
# Those are CVE-only, not schedule-driven, and do not conflict with our
# pinning strategy — they fire when a pinned version becomes known-bad,

# pull :main; users who want stable releases pull :latest.
#
# The real serialization guarantee comes from the top-level concurrency
# group (`docker-${{ github.ref }}` with `cancel-in-progress: false`),
# which ensures at most one workflow run for this ref executes at a time.
# That means two move-main steps for the same ref cannot overlap.
#
# This job has its own concurrency group as defense-in-depth: if the
# top-level group is ever loosened, queued move-mains will run serially
# in arrival order, each one running the ancestor check below and either
# advancing :main or skipping. `cancel-in-progress: false` matches the
# top-level setting — we don't want rapid pushes to cancel a queued
# move-main, because the ancestor check is the real safety mechanism
# and queueing is cheap (move-main is a ~30s registry op).
#
# Combined with the ancestor check, this means :main only ever moves
# forward in git history.

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.

## ❌ uv.lock is out of sync with pyproject.toml
**If this is a PR:** this check runs against the merged state
(your branch + current `main`), not just your branch. If
`uv lock --check` passes locally, your branch is likely behind
`main` — recent changes to `pyproject.toml` on `main` aren't
reflected in your branch's `uv.lock` yet.
To fix, sync with main and regenerate the lockfile:
```bash
git fetch origin main
git rebase origin/main # or `git merge origin/main`
uv lock # regenerate against new pyproject.toml
git add uv.lock
git commit -m "chore: refresh uv.lock after syncing with main"
git push --force-with-lease # drop --force-with-lease if you merged
```
**If you only changed pyproject.toml:** run `uv lock` locally
and commit the result.
This check is blocking because the Docker image build uses
`uv sync --frozen --extra all`, which rejects stale lockfiles
— catching it here avoids a ~15 min failed docker-publish run
on `main` post-merge.

### TUI in the Dashboard (`hermes dashboard` → `/chat`)
The dashboard embeds the real `hermes --tui`**not** a rewrite. See `hermes_cli/pty_bridge.py` + the `@app.websocket("/api/pty")` endpoint in `hermes_cli/web_server.py`.
- Browser loads `web/src/pages/ChatPage.tsx`, which mounts xterm.js's `Terminal` with the WebGL renderer, `@xterm/addon-fit` for container-driven resize, and `@xterm/addon-unicode11` for modern wide-character widths.
- `/api/pty?token=…` upgrades to a WebSocket; auth uses the same ephemeral `_SESSION_TOKEN` as REST, via query param (browsers can't set `Authorization` on WS upgrade).
- The server spawns whatever `hermes --tui` would spawn, through `ptyprocess` (POSIX PTY — WSL works, native Windows does not).
- Frames: raw PTY bytes each direction; resize via `\x1b[RESIZE:<cols>;<rows>]` intercepted on the server and applied with `TIOCSWINSZ`.
**Do not re-implement the primary chat experience in React.** The main transcript, composer/input flow (including slash-command behavior), and PTY-backed terminal belong to the embedded `hermes --tui` — anything new you add to Ink shows up in the dashboard automatically. If you find yourself rebuilding the transcript or composer for the dashboard, stop and extend Ink instead.
**Structured React UI around the TUI is allowed when it is not a second chat surface.** Sidebar widgets, inspectors, summaries, status panels, and similar supporting views (e.g. `ChatSidebar`, `ModelPickerDialog`, `ToolCall`) are fine when they complement the embedded TUI rather than replacing the transcript / composer / terminal. Keep their state independent of the PTY child's session and surface their failures non-destructively so the terminal pane keeps working unimpaired.

## Adding New Tools
For most custom or local-only tools, do **not** edit Hermes core. Use the plugin
route instead: create `~/.hermes/plugins/<name>/plugin.yaml` and
`~/.hermes/plugins/<name>/__init__.py`, then register tools with
`ctx.register_tool(...)`. Plugin toolsets are discovered automatically and can be
enabled or disabled without touching `tools/` or `toolsets.py`.
Use the built-in route below only when the user is explicitly contributing a new
core Hermes tool that should ship in the base system.

### Working directory:
- **CLI** — uses the process's current directory (`os.getcwd()`).
- **Messaging** — uses `terminal.cwd` from `config.yaml`. The gateway bridges this
to the `TERMINAL_CWD` env var for child tools. **`MESSAGING_CWD` has been
removed** — the config loader prints a deprecation warning if it's set in
`.env`. Same for `TERMINAL_CWD` in `.env`; the canonical setting is
`terminal.cwd` in `config.yaml`.

## Plugins
Hermes has two plugin surfaces. Both live under `plugins/` in the repo so
repo-shipped plugins can be discovered alongside user-installed ones in
`~/.hermes/plugins/` and pip-installed entry points.
### General plugins (`hermes_cli/plugins.py` + `plugins/<name>/`)
`PluginManager` discovers plugins from `~/.hermes/plugins/`, `./.hermes/plugins/`,
and pip entry points. Each plugin exposes a `register(ctx)` function that
can:
- Register Python-callback lifecycle hooks:
`pre_tool_call`, `post_tool_call`, `pre_llm_call`, `post_llm_call`,
`on_session_start`, `on_session_end`
- Register new tools via `ctx.register_tool(...)`
- Register CLI subcommands via `ctx.register_cli_command(...)` — the
plugin's argparse tree is wired into `hermes` at startup so
`hermes <pluginname> <subcmd>` works with no change to `main.py`
Hooks are invoked from `model_tools.py` (pre/post tool) and `run_agent.py`
(lifecycle). **Discovery timing pitfall:** `discover_plugins()` only runs
as a side effect of importing `model_tools.py`. Code paths that read plugin
state without importing `model_tools.py` first must call `discover_plugins()`
explicitly (it's idempotent).
### Memory-provider plugins (`plugins/memory/<name>/`)
Separate discovery system for pluggable memory backends. Current built-in
providers include **honcho, mem0, supermemory, byterover, hindsight,
holographic, openviking, retaindb**.
Each provider implements the `MemoryProvider` ABC (see `agent/memory_provider.py`)
and is orchestrated by `agent/memory_manager.py`. Lifecycle hooks include
`sync_turn(turn_messages)`, `prefetch(query)`, `shutdown()`, and optional
`post_setup(hermes_home, config)` for setup-wizard integration.
**CLI commands via `plugins/memory/<name>/cli.py`:** if a memory plugin
defines `register_cli(subparser)`, `discover_plugin_cli_commands()` finds
it at argparse setup time and wires it into `hermes <plugin>`. The
framework only exposes CLI commands for the **currently active** memory
provider (read from `memory.provider` in config.yaml), so disabled
providers don't clutter `hermes --help`.
**Rule (Teknium, May 2026):** plugins MUST NOT modify core files
(`run_agent.py`, `cli.py`, `gateway/run.py`, `hermes_cli/main.py`, etc.).
If a plugin needs a capability the framework doesn't expose, expand the
generic plugin surface (new hook, new ctx method) — never hardcode
plugin-specific logic into core. PR #5295 removed 95 lines of hardcoded
honcho argparse from `main.py` for exactly this reason.
**No new in-tree memory providers (policy, May 2026):** the set of
built-in memory providers under `plugins/memory/` is closed. New memory
backends must ship as **standalone plugin repos** that users install
into `~/.hermes/plugins/` (or via pip entry points) — they implement
the same `MemoryProvider` ABC, register through the same discovery
path, and integrate via `hermes memory setup` / `post_setup()` without
landing in this tree. PRs that add a new directory under
`plugins/memory/` will be closed with a pointer to publish the
provider as its own repo. Existing in-tree providers stay; bug fixes
to them are welcome.
### Model-provider plugins (`plugins/model-providers/<name>/`)
Every inference backend (openrouter, anthropic, gmi, deepseek, nvidia, …)
ships as a plugin here. Each plugin's `__init__.py` calls
`providers.register_provider(ProviderProfile(...))` at module load.
`providers/__init__.py._discover_providers()` is a **lazy, separate
discovery system** — scanned on first `get_provider_profile()` or
`list_providers()` call, NOT by the general PluginManager.
Scan order:
1. Bundled: `<repo>/plugins/model-providers/<name>/`
2. User: `$HERMES_HOME/plugins/model-providers/<name>/`
3. Legacy: `<repo>/providers/<name>.py` (back-compat)
User plugins of the same name override bundled ones — `register_provider()`
is last-writer-wins. This lets third parties swap out any built-in
profile without a repo patch.
The general PluginManager records `kind: model-provider` manifests but does
NOT import them (would double-instantiate `ProviderProfile`). Plugins
without an explicit `kind:` get auto-coerced via a source-text heuristic
(`register_provider` + `ProviderProfile` in `__init__.py`).
Full authoring guide: `website/docs/developer-guide/model-provider-plugin.md`.
### Dashboard / context-engine / image-gen plugin directories
`plugins/context_engine/`, `plugins/image_gen/`, etc. follow the same
pattern (ABC + orchestrator + per-plugin directory). Context engines
plug into `agent/context_engine.py`; image-gen providers into
`agent/image_gen_provider.py`. Reference / docs-companion plugins
(`example-dashboard`, `strike-freedom-cockpit`, `plugin-llm-example`,
`plugin-llm-async-example`) live in the
[`hermes-example-plugins`](https://github.com/NousResearch/hermes-example-plugins)
companion repo, not in this tree.
---
## Skills
Two parallel surfaces:
- **`skills/`** — built-in skills shipped and loadable by default.
Organized by category directories (e.g. `skills/github/`, `skills/mlops/`).
- **`optional-skills/`** — heavier or niche skills shipped with the repo but
NOT active by default. Installed explicitly via
`hermes skills install official/<category>/<skill>`. Adapter lives in
`tools/skills_hub.py` (`OptionalSkillSource`). Categories include
`autonomous-ai-agents`, `blockchain`, `communication`, `creative`,
`devops`, `email`, `health`, `mcp`, `migration`, `mlops`, `productivity`,
`research`, `security`, `web-development`.
When reviewing skill PRs, check which directory they target — heavy-dep or
niche skills belong in `optional-skills/`.
### SKILL.md frontmatter
Standard fields: `name`, `description`, `version`, `author`, `license`,
`platforms` (OS-gating list: `[macos]`, `[linux, macos]`, ...),
`metadata.hermes.tags`, `metadata.hermes.category`,
`metadata.hermes.related_skills`, `metadata.hermes.config` (config.yaml
settings the skill needs — stored under `skills.config.<key>`, prompted
during setup, injected at load time).
Top-level `tags:` and `category:` are also accepted and mirrored from
`metadata.hermes.*` by the loader.
### 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.
The full salvage / modernization checklist for external skill PRs
lives in the `hermes-agent-dev` skill at
`references/new-skill-pr-salvage.md` — load it before polishing
contributor skill PRs.
---
## 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 120s2h.
- 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.

### DO NOT hardcode cross-tool references in schema descriptions
Tool schema descriptions must not mention tools from other toolsets by name (e.g., `browser_navigate` saying "prefer web_search"). Those tools may be unavailable (missing API keys, disabled toolset), causing the model to hallucinate calls to non-existent tools. If a cross-reference is needed, add it dynamically in `get_tool_definitions()` in `model_tools.py` — see the `browser_navigate` / `execute_code` post-processing blocks for the pattern.
### The gateway has TWO message guards — both must bypass approval/control commands
When an agent is running, messages pass through two sequential guards:
(1) **base adapter** (`gateway/platforms/base.py`) queues messages in
`_pending_messages` when `session_key in self._active_sessions`, and
(2) **gateway runner** (`gateway/run.py`) intercepts `/stop`, `/new`,
`/queue`, `/status`, `/approve`, `/deny` before they reach
`running_agent.interrupt()`. Any new command that must reach the runner
while the agent is blocked (e.g. approval prompts) MUST bypass BOTH
guards and be dispatched inline, not via `_process_message_background()`
(which races session lifecycle).
### Squash merges from stale branches silently revert recent fixes
Before squash-merging a PR, ensure the branch is up to date with `main`
(`git fetch origin main && git reset --hard origin/main` in the worktree,
then re-apply the PR's commits). A stale branch's version of an unrelated
file will silently overwrite recent fixes on main when squashed. Verify
with `git diff HEAD~1..HEAD` after merging — unexpected deletions are a
red flag.
### Don't wire in dead code without E2E validation
Unused code that was never shipped was dead for a reason. Before wiring an
unused module into a live code path, E2E test the real resolution chain
with actual imports (not mocks) against a temp `HERMES_HOME`.

## Memory Providers: Ship as a Standalone Plugin
**We are no longer accepting new memory providers into this repo.** The set of built-in providers under `plugins/memory/` (honcho, mem0, supermemory, byterover, hindsight, holographic, openviking, retaindb) is closed. If you want to add a new memory backend, publish it as a **standalone plugin repo** that users install into `~/.hermes/plugins/` (or via a pip entry point).
Standalone memory plugins:
- Implement the same `MemoryProvider` ABC (`agent/memory_provider.py`) — `sync_turn`, `prefetch`, `shutdown`, and optionally `post_setup(hermes_home, config)` for setup-wizard integration
- Use the same discovery system — `discover_memory_providers()` picks them up from user/project plugin directories and pip entry points
- Integrate with `hermes memory setup` via `post_setup()` — no need to touch core code
- Can register their own CLI subcommands via `register_cli(subparser)` in a `cli.py` file
- Get all the same lifecycle hooks and config plumbing as in-tree providers
PRs that add a new directory under `plugins/memory/` will be closed with a pointer to publish the provider as its own repo. Existing in-tree providers stay; bug fixes to them are welcome.
This isn't a quality bar — it's a coupling-and-maintenance decision. Memory providers are the most common plugin type and they shouldn't all live in this tree.

Good: `Search arXiv papers by keyword, author, category, or ID.`
Bad: `A powerful and comprehensive skill that allows the agent to search arXiv for relevant academic papers using various criteria including keywords, authors, and categories.`
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` ``, `` `web_search` ``, `` `read_file` ``, `` `write_file` ``, `` `patch` ``, `` `search_files` ``, `` `vision_analyze` ``, `` `browser_navigate` ``, `` `delegate_task` ``, `` `image_generate` ``, `` `text_to_speech` ``, `` `cronjob` ``, `` `memory` ``, `` `skill_view` ``, `` `todo` ``, `` `execute_code` ``.
Do NOT name shell utilities the agent already has wrapped:
| Don't say | Say |
|---|---|
| `grep`, `rg` | `search_files` |
| `cat`, `head`, `tail` | `read_file` |
| `sed`, `awk` | `patch` |
| `find`, `ls` | `search_files` (with `target='files'`) |
| `curl` for content extraction | `web_extract` |
| `echo > file`, `cat <<EOF` | `write_file` |
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.
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`, hardcoded `/tmp` paths, `signal.SIGKILL`, bash heredocs, `osascript`, `apt`, `systemctl`) must declare their supported platforms via the `platforms:` frontmatter. Default posture is 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 (e.g. `osascript` is macOS-only, `/proc` is Linux-only).
4. **`author` credits the human contributor first.** For external contributions, the contributor's real name + GitHub handle goes first (`Jane Doe (jane-doe)`); "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 what it doesn't do, then:
- `## When to Use` — trigger conditions
- `## Prerequisites` — env vars, install steps, MCP setup, API key sourcing
- `## How to Run` — canonical invocation through the `terminal` tool
- `## Quick Reference` — flat command/API reference
- `## Procedure` — numbered steps with copy-paste commands
- `## Pitfalls` — known limits, rate limits, things that look broken but aren't
- `## Verification` — single command that proves the skill works
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 documented 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 scripts 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`. Must pass under the hermetic CI env (no API keys leaking through). Use `monkeypatch` and `tmp_path` for any env-var or filesystem dependencies.
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 will be dropped during salvage. Comment all values with `#` (it's documentation, not live config).

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

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

4. **File encoding.** Windows may save `.env` files in `cp1252`. Always
handle encoding errors:
2. **File encoding.** Windows may save `.env` files in `cp1252`. Always handle encoding errors:
```python
try:
load_dotenv(env_path)
except UnicodeDecodeError:
load_dotenv(env_path, encoding="latin-1")
```
Config files (`config.yaml`) may be saved with a UTF-8 BOM by Notepad and
similar editors — use `encoding="utf-8-sig"` when reading files that
could have been touched by a Windows GUI editor.
5. **Process management.** `os.setsid()`, `os.killpg()`, `os.fork()`,
`os.getuid()`, and POSIX signal handling differ on Windows. Guard with
`platform.system()`, `sys.platform`, or `hasattr(os, "setsid")`:
3. **Process management.** `os.setsid()`, `os.killpg()`, and signal handling differ on Windows. Use platform checks:
```python
import platform
if platform.system() != "Windows":
kwargs["preexec_fn"] = os.setsid
else:
kwargs["creationflags"] = subprocess.CREATE_NEW_PROCESS_GROUP
```
**Preferred:** for killing a process AND its children (what `os.killpg`
does on POSIX), use `psutil` — it works on every platform:
```python
import psutil
try:
parent = psutil.Process(pid)
# Kill children first (leaf-up), then the parent.
for child in parent.children(recursive=True):
child.kill()
parent.kill()
except psutil.NoSuchProcess:
pass
```
4. **Path separators.** Use `pathlib.Path` instead of string concatenation with `/`.
6. **Signals that don't exist on Windows: `SIGALRM`, `SIGCHLD`, `SIGHUP`,
`SIGUSR1`, `SIGUSR2`, `SIGPIPE`, `SIGQUIT`, `SIGKILL`.** Python's
`signal` module raises `AttributeError` at import time if you reference
them on Windows. Use `getattr(signal, "SIGKILL", signal.SIGTERM)` or
gate the whole block behind a platform check. `loop.add_signal_handler`
raises `NotImplementedError` on Windows — always catch it.
7. **Path separators.** Use `pathlib.Path` instead of string concatenation
with `/`. Forward slashes work almost everywhere on Windows, but
`subprocess.run(["cmd.exe", "/c", ...])` and other shell contexts can
require backslashes — convert with `str(path)` at the subprocess boundary,
not inside Python logic.
8. **Symlinks need elevated privileges on Windows** (unless Developer Mode is
on). Tests that create symlinks need `@pytest.mark.skipif(sys.platform ==
"win32", reason="Symlinks require elevated privileges on Windows")`.
9. **POSIX file modes (0o600, 0o644, etc.) are NOT enforced on NTFS** by
default. Tests that assert on `stat().st_mode & 0o777` must skip on
Windows — the concept doesn't translate. Use ACLs (`icacls`, `pywin32`)
for Windows secret-file protection if needed.
10. **Detached background daemons on Windows need `pythonw.exe`, NOT
`python.exe`.** `python.exe` always allocates or attaches to a console,
which makes it vulnerable to `CTRL_C_EVENT` broadcasts from any sibling
process. `pythonw.exe` is the no-console variant. Combine with
`CREATE_NO_WINDOW | DETACHED_PROCESS | CREATE_NEW_PROCESS_GROUP |
CREATE_BREAKAWAY_FROM_JOB` in `subprocess.Popen(creationflags=...)`.
See `hermes_cli/gateway_windows.py::_spawn_detached` for the reference
implementation.
11. **`subprocess.Popen` with `.cmd` or `.bat` shims needs `shutil.which`
to resolve.** Passing `"agent-browser"` to `Popen` on Windows finds
the extensionless POSIX shebang shim in `node_modules/.bin/`, which
`CreateProcessW` can't execute — you'll get `WinError 193 "not a valid
Win32 application"`. Use `shutil.which("agent-browser", path=local_bin)`
which honors PATHEXT and picks the `.CMD` variant on Windows.
12. **Don't use shell shebangs as a way to run Python.** `#!/usr/bin/env
python` only works when the file is executed through a Unix shell.
`subprocess.run(["./myscript.py"])` on Windows fails even if the file
has a shebang line. Always invoke Python explicitly:
`[sys.executable, "myscript.py"]`.
13. **Shell commands in installers.** If you change `scripts/install.sh`,
make the equivalent change in `scripts/install.ps1`. The two scripts
are the canonical example of "works on Linux does not mean works on
Windows" and have drifted multiple times — keep them in lockstep.
14. **Known paths that are OneDrive-redirected on Windows:** Desktop,
Documents, Pictures, Videos. The "real" path when OneDrive Backup is
enabled is `%USERPROFILE%\OneDrive\Desktop` (etc.), NOT
`%USERPROFILE%\Desktop` (which exists as an empty husk). Resolve the
real location via `ctypes` + `SHGetKnownFolderPath` or by reading the
`Shell Folders` registry key — never assume `~/Desktop`.
15. **CRLF vs LF in generated scripts.** Windows `cmd.exe` and `schtasks`
parse line-by-line; mixed or LF-only line endings can break multi-line
`.cmd` / `.bat` files. Use `open(path, "w", encoding="utf-8",
newline="\r\n")` — or `open(path, "wb")` + explicit bytes — when
generating scripts Windows will execute.
16. **Two different quoting schemes in one command line.** `subprocess.run
(["schtasks", "/TR", some_cmd])` → schtasks itself parses `/TR`, AND
the `some_cmd` string is re-parsed by `cmd.exe` when the task fires.
Different parsers, different escape rules. Use two separate quoting
helpers and never cross them. See `hermes_cli/gateway_windows.py::
_quote_cmd_script_arg` and `_quote_schtasks_arg` for the reference
pair.
### Testing cross-platform
Tests that use POSIX-only syscalls need a skip marker. Common ones:
- Symlinks → `@pytest.mark.skipif(sys.platform == "win32", ...)`
- `0o600` file modes → `@pytest.mark.skipif(sys.platform.startswith("win"), ...)`
- `signal.SIGALRM` → Unix-only (see `tests/conftest.py::_enforce_test_timeout`)
- `os.setsid` / `os.fork` → Unix-only
- Live Winsock / Windows-specific regression tests →
`@pytest.mark.skipif(sys.platform != "win32", reason="Windows-specific regression")`
If you monkeypatch `sys.platform` for cross-platform tests, also patch
`platform.system()` / `platform.release()` / `platform.mac_ver()` — each
re-reads the real OS independently, so half-patched tests still route
through the wrong branch on a Windows runner.
5. **Shell commands in installers.** If you change `scripts/install.sh`, check if the equivalent change is needed in `scripts/install.ps1`.

### Linux, macOS, WSL2, Termux

### Windows (native, PowerShell) — Early Beta
> **Heads up:** Native Windows support is **early beta**. It installs and runs, but hasn't been road-tested as broadly as our Linux/macOS/WSL2 paths. Please [file issues](https://github.com/NousResearch/hermes-agent/issues) when you hit rough edges. For the most battle-tested Windows setup today, run the Linux/macOS one-liner above inside **WSL2**.
Run this in PowerShell:
```powershell
irm https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.ps1 | iex
```
The installer handles everything: uv, Python 3.11, Node.js, ripgrep, ffmpeg, **and a portable Git Bash** (MinGit, unpacked to `%LOCALAPPDATA%\hermes\git` — no admin required, completely isolated from any system Git install). Hermes uses this bundled Git Bash to run shell commands.
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.
Works on Linux, macOS, WSL2, and Android via Termux. The installer handles the platform-specific setup for you.
> **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).
> **Windows:** Native Windows is not supported. Please install [WSL2](https://learn.microsoft.com/en-us/windows/wsl/install) and run the command above.

# Hermes Agent v0.11.0 (v2026.4.23)
**Release Date:** April 23, 2026
**Since v0.9.0:** 1,556 commits · 761 merged PRs · 1,314 files changed · 224,174 insertions · 29 community contributors (290 including co-authors)
> The Interface release — a full React/Ink rewrite of the interactive CLI, a pluggable transport architecture underneath every provider, native AWS Bedrock support, five new inference paths, a 17th messaging platform (QQBot), a dramatically expanded plugin surface, and GPT-5.5 via Codex OAuth.
This release also folds in all the highlights deferred from v0.10.0 (which shipped only the Nous Tool Gateway) — so it covers roughly two weeks of work across the whole stack.
---
## ✨ Highlights
- **New Ink-based TUI** — `hermes --tui` is now a full React/Ink rewrite of the interactive CLI, with a Python JSON-RPC backend (`tui_gateway`). Sticky composer, live streaming with OSC-52 clipboard support, stable picker keys, status bar with per-turn stopwatch and git branch, `/clear` confirm, light-theme preset, and a subagent spawn observability overlay. ~310 commits to `ui-tui/` + `tui_gateway/`. (@OutThisLife + Teknium)
- **Transport ABC + Native AWS Bedrock** — Format conversion and HTTP transport were extracted from `run_agent.py` into a pluggable `agent/transports/` layer. `AnthropicTransport`, `ChatCompletionsTransport`, `ResponsesApiTransport`, and `BedrockTransport` each own their own format conversion and API shape. Native AWS Bedrock support via the Converse API ships on top of the new abstraction. ([#10549](https://github.com/NousResearch/hermes-agent/pull/10549), [#13347](https://github.com/NousResearch/hermes-agent/pull/13347), [#13366](https://github.com/NousResearch/hermes-agent/pull/13366), [#13430](https://github.com/NousResearch/hermes-agent/pull/13430), [#13805](https://github.com/NousResearch/hermes-agent/pull/13805), [#13814](https://github.com/NousResearch/hermes-agent/pull/13814) — @kshitijk4poor + Teknium)
- **Five new inference paths** — Native NVIDIA NIM ([#11774](https://github.com/NousResearch/hermes-agent/pull/11774)), Arcee AI ([#9276](https://github.com/NousResearch/hermes-agent/pull/9276)), Step Plan ([#13893](https://github.com/NousResearch/hermes-agent/pull/13893)), Google Gemini CLI OAuth ([#11270](https://github.com/NousResearch/hermes-agent/pull/11270)), and Vercel ai-gateway with pricing + dynamic discovery ([#13223](https://github.com/NousResearch/hermes-agent/pull/13223) — @jerilynzheng). Plus Gemini routed through the native AI Studio API for better performance ([#12674](https://github.com/NousResearch/hermes-agent/pull/12674)).
- **GPT-5.5 over Codex OAuth** — OpenAI's new GPT-5.5 reasoning model is now available through your ChatGPT Codex OAuth, with live model discovery wired into the model picker so new OpenAI releases show up without catalog updates. ([#14720](https://github.com/NousResearch/hermes-agent/pull/14720))
- **QQBot — 17th supported platform** — Native QQBot adapter via QQ Official API v2, with QR scan-to-configure setup wizard, streaming cursor, emoji reactions, and DM/group policy gating that matches WeCom/Weixin parity. ([#9364](https://github.com/NousResearch/hermes-agent/pull/9364), [#11831](https://github.com/NousResearch/hermes-agent/pull/11831))
- **Plugin surface expanded** — Plugins can now register slash commands (`register_command`), dispatch tools directly (`dispatch_tool`), block tool execution from hooks (`pre_tool_call` can veto), rewrite tool results (`transform_tool_result`), transform terminal output (`transform_terminal_output`), ship image_gen backends, and add custom dashboard tabs. The bundled disk-cleanup plugin is opt-in by default as a reference implementation. ([#9377](https://github.com/NousResearch/hermes-agent/pull/9377), [#10626](https://github.com/NousResearch/hermes-agent/pull/10626), [#10763](https://github.com/NousResearch/hermes-agent/pull/10763), [#10951](https://github.com/NousResearch/hermes-agent/pull/10951), [#12929](https://github.com/NousResearch/hermes-agent/pull/12929), [#12944](https://github.com/NousResearch/hermes-agent/pull/12944), [#12972](https://github.com/NousResearch/hermes-agent/pull/12972), [#13799](https://github.com/NousResearch/hermes-agent/pull/13799), [#14175](https://github.com/NousResearch/hermes-agent/pull/14175))
- **`/steer` — mid-run agent nudges** — `/steer <prompt>` injects a note that the running agent sees after its next tool call, without interrupting the turn or breaking prompt cache. For when you want to course-correct an agent in-flight. ([#12116](https://github.com/NousResearch/hermes-agent/pull/12116))
- **Shell hooks** — Wire any shell script as a Hermes lifecycle hook (pre_tool_call, post_tool_call, on_session_start, etc.) without writing a Python plugin. ([#13296](https://github.com/NousResearch/hermes-agent/pull/13296))
- **Webhook direct-delivery mode** — Webhook subscriptions can now forward payloads straight to a platform chat without going through the agent — zero-LLM push notifications for alerting, uptime checks, and event streams. ([#12473](https://github.com/NousResearch/hermes-agent/pull/12473))
- **Smarter delegation** — Subagents now have an explicit `orchestrator` role that can spawn their own workers, with configurable `max_spawn_depth` (default flat). Concurrent sibling subagents share filesystem state through a file-coordination layer so they don't clobber each other's edits. ([#13691](https://github.com/NousResearch/hermes-agent/pull/13691), [#13718](https://github.com/NousResearch/hermes-agent/pull/13718))
- **Auxiliary models — configurable UI + main-model-first** — `hermes model` has a dedicated "Configure auxiliary models" screen for per-task overrides (compression, vision, session_search, title_generation). `auto` routing now defaults to the main model for side tasks across all users (previously aggregator users were silently routed to a cheap provider-side default). ([#11891](https://github.com/NousResearch/hermes-agent/pull/11891), [#11900](https://github.com/NousResearch/hermes-agent/pull/11900))
- **Dashboard plugin system + live theme switching** — The web dashboard is now extensible. Third-party plugins can add custom tabs, widgets, and views without forking. Paired with a live-switching theme system — themes now control colors, fonts, layout, and density — so users can hot-swap the dashboard look without a reload. Same theming discipline the CLI has, now on the web. ([#10951](https://github.com/NousResearch/hermes-agent/pull/10951), [#10687](https://github.com/NousResearch/hermes-agent/pull/10687), [#14725](https://github.com/NousResearch/hermes-agent/pull/14725))
- **Dashboard polish** — i18n (English + Chinese), react-router sidebar layout, mobile-responsive, Vercel deployment, real per-session API call tracking, and one-click update + gateway restart buttons. ([#9228](https://github.com/NousResearch/hermes-agent/pull/9228), [#9370](https://github.com/NousResearch/hermes-agent/pull/9370), [#9453](https://github.com/NousResearch/hermes-agent/pull/9453), [#10686](https://github.com/NousResearch/hermes-agent/pull/10686), [#13526](https://github.com/NousResearch/hermes-agent/pull/13526), [#14004](https://github.com/NousResearch/hermes-agent/pull/14004) — @austinpickett + @DeployFaith + Teknium)

# Hermes Agent v0.12.0 (v2026.4.30)
**Release Date:** April 30, 2026
**Since v0.11.0:** 1,096 commits · 550 merged PRs · 1,270 files changed · 217,776 insertions · 213 community contributors (including co-authors)
> The Curator release — Hermes Agent now maintains itself. An autonomous background Curator grades, prunes, and consolidates your skill library on its own schedule. The self-improvement loop that reviews what to save got a substantial upgrade. Four new inference providers, a 18th messaging platform, a 19th via Teams plugin, native Spotify + Google Meet integrations, ComfyUI and TouchDesigner-MCP moved from optional to bundled-by-default, and a ~57% cut to visible TUI cold start.
---
## ✨ Highlights
- **Autonomous Curator** — `hermes curator` runs as a background agent on the gateway's cron ticker (7-day cycle default). It grades your skill library, consolidates related skills, prunes dead ones, and writes per-run reports to `logs/curator/run.json` + `REPORT.md`. Archived skills are classified consolidated-vs-pruned via model + heuristic. Defense-in-depth gates protect bundled/hub skills from mutation. Unified under `auxiliary.curator` — pick the curator's model in `hermes model`, manage it from the dashboard. `hermes curator status` ranks skills by usage (most-used / least-used). ([#17277](https://github.com/NousResearch/hermes-agent/pull/17277), [#17307](https://github.com/NousResearch/hermes-agent/pull/17307), [#17941](https://github.com/NousResearch/hermes-agent/pull/17941), [#17868](https://github.com/NousResearch/hermes-agent/pull/17868), [#18033](https://github.com/NousResearch/hermes-agent/pull/18033))
- **Self-improvement loop — substantially upgraded** — The background review fork (the core of Hermes' self-improvement: after each turn it decides what memories/skills to save or update) is now class-first (rubric-based rather than free-form), active-update biased (prefers the skill the agent just loaded), handles `references/`/`templates/` sub-files, and properly inherits the parent's live runtime (provider, model, credentials actually propagate). Restricted to memory + skills toolsets so it can't sprawl. Memory providers shut down cleanly. Prior-turn tool messages excluded from the summary so the fork sees a clean context. ([#16026](https://github.com/NousResearch/hermes-agent/pull/16026), [#17213](https://github.com/NousResearch/hermes-agent/pull/17213), [#16099](https://github.com/NousResearch/hermes-agent/pull/16099), [#16569](https://github.com/NousResearch/hermes-agent/pull/16569), [#16204](https://github.com/NousResearch/hermes-agent/pull/16204), [#15057](https://github.com/NousResearch/hermes-agent/pull/15057))
- **Skill integrations — major expansion** — **ComfyUI v5** with official CLI + REST + hardware-gated local install, moved from optional to **built-in by default** ([#17610](https://github.com/NousResearch/hermes-agent/pull/17610), [#17631](https://github.com/NousResearch/hermes-agent/pull/17631), [#17734](https://github.com/NousResearch/hermes-agent/pull/17734)). **TouchDesigner-MCP** bundled by default, expanded with GLSL, post-FX, audio, geometry, and 9 new reference docs ([#16753](https://github.com/NousResearch/hermes-agent/pull/16753), [#16624](https://github.com/NousResearch/hermes-agent/pull/16624), [#16768](https://github.com/NousResearch/hermes-agent/pull/16768) — @kshitijk4poor + @SHL0MS). **Humanizer** skill ports a text-cleaner that strips AI-isms ([#16787](https://github.com/NousResearch/hermes-agent/pull/16787)). **claude-design** HTML artifact skill + design-md (Google DESIGN.md spec) + airtable salvage + `skill_manage` edits in `external_dirs` + direct-URL skill install + `/reload-skills` slash command. ([#16358](https://github.com/NousResearch/hermes-agent/pull/16358), [#14876](https://github.com/NousResearch/hermes-agent/pull/14876), [#16291](https://github.com/NousResearch/hermes-agent/pull/16291), [#17512](https://github.com/NousResearch/hermes-agent/pull/17512), [#16323](https://github.com/NousResearch/hermes-agent/pull/16323), [#17744](https://github.com/NousResearch/hermes-agent/pull/17744))
- **LM Studio — first-class provider** — upgraded from a custom-endpoint alias to a full-blown native provider: dedicated auth, `hermes doctor` checks, reasoning transport, live `/models` listing. (Salvage of @kshitijk4poor's #17061.) ([#17102](https://github.com/NousResearch/hermes-agent/pull/17102))
- **Four more new inference providers** — **GMI Cloud** (first-class, salvage of #11955@isaachuangGMICLOUD), **Azure AI Foundry** with auto-detection, **MiniMax OAuth** with PKCE browser flow (salvage #15203), **Tencent Tokenhub** (salvage of #16860). ([#16663](https://github.com/NousResearch/hermes-agent/pull/16663), [#15845](https://github.com/NousResearch/hermes-agent/pull/15845), [#17524](https://github.com/NousResearch/hermes-agent/pull/17524), [#16960](https://github.com/NousResearch/hermes-agent/pull/16960))
- **Pluggable gateway platforms + Microsoft Teams** — the gateway is now a plugin host. Drop-in messaging adapters live outside the core, and Microsoft Teams is the first plugin-shipped platform. (Salvage of #17664.) ([#17751](https://github.com/NousResearch/hermes-agent/pull/17751), [#17828](https://github.com/NousResearch/hermes-agent/pull/17828))
- **Tencent 元宝 (Yuanbao) — 18th messaging platform** — native gateway adapter with text + media delivery. ([#16298](https://github.com/NousResearch/hermes-agent/pull/16298), [#17424](https://github.com/NousResearch/hermes-agent/pull/17424))
- **Spotify — native tools + bundled skill + wizard** — 7 tools (play, search, queue, playlists, devices) behind PKCE OAuth, interactive setup wizard, bundled skill, surfacing in `hermes tools`, cron usage documented. ([#15121](https://github.com/NousResearch/hermes-agent/pull/15121), [#15130](https://github.com/NousResearch/hermes-agent/pull/15130), [#15154](https://github.com/NousResearch/hermes-agent/pull/15154), [#15180](https://github.com/NousResearch/hermes-agent/pull/15180))
- **Google Meet plugin** — join calls, transcribe, speak, follow up. Realtime OpenAI transport + Node bot server, full pipeline bundled as a plugin. ([#16364](https://github.com/NousResearch/hermes-agent/pull/16364))
- **`hermes -z` one-shot mode + `hermes update --check`** — non-interactive `hermes -z <prompt>` with `--model`/`--provider`/`HERMES_INFERENCE_MODEL`. `hermes update --check` preflight. Opt-in pre-update HERMES_HOME backup. ([#15702](https://github.com/NousResearch/hermes-agent/pull/15702), [#15704](https://github.com/NousResearch/hermes-agent/pull/15704), [#15841](https://github.com/NousResearch/hermes-agent/pull/15841), [#16539](https://github.com/NousResearch/hermes-agent/pull/16539), [#16566](https://github.com/NousResearch/hermes-agent/pull/16566))
- **Models dashboard tab + in-browser model config** — rich per-model analytics, switch main + auxiliary models from the dashboard. ([#17745](https://github.com/NousResearch/hermes-agent/pull/17745), [#17802](https://github.com/NousResearch/hermes-agent/pull/17802))
- **Remote model catalog manifest** — OpenRouter + Nous Portal model catalogs are now pulled from a remote manifest so new models show up without a release. ([#16033](https://github.com/NousResearch/hermes-agent/pull/16033))
- **Native multimodal image routing** — images now route based on the model's actual vision capability rather than provider defaults. ([#16506](https://github.com/NousResearch/hermes-agent/pull/16506))
- **Gateway media parity** — native multi-image sending across Telegram, Discord, Slack, Mattermost, Email, and Signal; centralized audio routing with FLAC support + Telegram document fallback. ([#17909](https://github.com/NousResearch/hermes-agent/pull/17909), [#17833](https://github.com/NousResearch/hermes-agent/pull/17833))
- **TUI catches up to (and past) the classic CLI** — LaTeX rendering (@austinpickett), `/reload` .env hot-reload, pluggable busy-indicator styles (@OutThisLife, #13610), opt-in auto-resume of last session, expanded light-terminal auto-detection, session delete from `/resume` picker with `d`, modified mouse-wheel line scroll, and a `/mouse` toggle that kills ConPTY's phantom mouse injection (@kevin-ho). ([#17175](https://github.com/NousResearch/hermes-agent/pull/17175), [#17286](https://github.com/NousResearch/hermes-agent/pull/17286), [#17150](https://github.com/NousResearch/hermes-agent/pull/17150), [#17130](https://github.com/NousResearch/hermes-agent/pull/17130), [#17113](https://github.com/NousResearch/hermes-agent/pull/17113), [#17668](https://github.com/NousResearch/hermes-agent/pull/17668), [#17669](https://github.com/NousResearch/hermes-agent/pull/17669), [#15488](https://github.com/NousResearch/hermes-agent/pull/15488))
- **Observability + achievements plugins** — bundled Langfuse observability plugin (salvage #16845) + bundled hermes-achievements plugin that scans full session history. ([#16917](https://github.com/NousResearch/hermes-agent/pull/16917), [#17754](https://github.com/NousResearch/hermes-agent/pull/17754))
- **TTS provider registry + Piper local TTS** — pluggable `tts.providers.<name>` registry; Piper ships as a native local TTS provider. (Closes #8508.) ([#17843](https://github.com/NousResearch/hermes-agent/pull/17843), [#17885](https://github.com/NousResearch/hermes-agent/pull/17885))
- **Vercel Sandbox backend** — Vercel sandboxes as an execute_code/terminal backend (@kshitijk4poor). ([#17445](https://github.com/NousResearch/hermes-agent/pull/17445))
- **Secret redaction off by default** — default flipped to off. Prevents the long-standing patch-corruption incidents where fake secret-shaped substrings mangled tool outputs. Opt in via `redaction.enabled: true` when you need it. ([#16794](https://github.com/NousResearch/hermes-agent/pull/16794))
- **Cold-start performance** — visible TUI cold start cut **~57%** via lazy agent init (@OutThisLife), lazy imports of OpenAI / Anthropic / Firecrawl / account_usage, mtime-cached `load_config()`, memoized `get_tool_definitions()` with TTL-cached `check_fn` results, precompiled dangerous-command patterns. ([#17190](https://github.com/NousResearch/hermes-agent/pull/17190), [#17046](https://github.com/NousResearch/hermes-agent/pull/17046), [#17041](https://github.com/NousResearch/hermes-agent/pull/17041), [#17098](https://github.com/NousResearch/hermes-agent/pull/17098), [#17206](https://github.com/NousResearch/hermes-agent/pull/17206))
- **Configurable prompt cache TTL** — `prompt_caching.cache_ttl` (5m default, 1h opt-in — cost savings for bursty sessions that keep cache warm). Salvage of #12659. ([#15065](https://github.com/NousResearch/hermes-agent/pull/15065))

## 🧠 Autonomous Curator & Self-Improvement Loop
### Curator — autonomous skill maintenance
- **`hermes curator` as a background agent** — runs on the gateway's cron ticker, 7-day cycle by default, umbrella-first prompt, inherits parent config, unbounded iterations ([#17277](https://github.com/NousResearch/hermes-agent/pull/17277) — issue #7816)
- **Per-run reports** — `logs/curator/run.json` + `REPORT.md` per cycle ([#17307](https://github.com/NousResearch/hermes-agent/pull/17307))
- **Consolidated vs pruned classification** — archived skills split with model + heuristic ([#17941](https://github.com/NousResearch/hermes-agent/pull/17941))
- **`hermes curator status`** — ranks skills by usage, shows most-used and least-used ([#18033](https://github.com/NousResearch/hermes-agent/pull/18033))
- **Unified under `auxiliary.curator`** — pick the model in `hermes model`, configure from the dashboard ([#17868](https://github.com/NousResearch/hermes-agent/pull/17868))
- **Documentation** — dedicated curator feature page on the docs site ([#17563](https://github.com/NousResearch/hermes-agent/pull/17563))
- Fix: seed defaults on update, create `logs/curator/` directory, defer fire import ([#17927](https://github.com/NousResearch/hermes-agent/pull/17927))
- Fix: scan nested archive subdirs in `restore_skill` (@0xDevNinja) ([#17951](https://github.com/NousResearch/hermes-agent/pull/17951))
- Fix: use actual skill activity in curator status (@y0shua1ee) ([#17953](https://github.com/NousResearch/hermes-agent/pull/17953))
- Fix: `skill_manage` refuses writes on pinned skills; pinning now blocks curator writes ([#17562](https://github.com/NousResearch/hermes-agent/pull/17562), [#17578](https://github.com/NousResearch/hermes-agent/pull/17578))
- Fix: `bump_use()` wired into skill invocation + preload + skill_view (salvage #17782) ([#17932](https://github.com/NousResearch/hermes-agent/pull/17932))
### Self-improvement loop (background review fork)
- **Class-first skill-review prompt** — rubric-based grading rather than free-form "should this update" ([#16026](https://github.com/NousResearch/hermes-agent/pull/16026))
- **Active-update bias** — prefers updating skills the agent just loaded, handles `references/` + `templates/` sub-files ([#17213](https://github.com/NousResearch/hermes-agent/pull/17213))
- **Fork inherits parent's live runtime** — provider, model, credentials actually propagate now ([#16099](https://github.com/NousResearch/hermes-agent/pull/16099))
- **Scoped toolsets** — review fork restricted to memory + skills (no shell, no web) ([#16569](https://github.com/NousResearch/hermes-agent/pull/16569))
- **Clean shutdown** — background review memory providers exit properly (salvage #15289) ([#16204](https://github.com/NousResearch/hermes-agent/pull/16204))
- **Clean context** — prior-history tool messages excluded from review summary (salvage #14967) ([#15057](https://github.com/NousResearch/hermes-agent/pull/15057))
---

# Hermes Agent v0.13.0 (v2026.5.7)
**Release Date:** May 7, 2026
**Since v0.12.0:** 864 commits · 588 merged PRs · 829 files changed · 128,366 insertions · 282 issues closed (13 P0, 36 P1) · 295 community contributors (including co-authors)
> 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))

# 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)

Image Generation Provider ABC

Providers live in ``<repo>/plugins/image_gen/<name>/`` (built-in, auto-loaded

via ``plugins.enabled``).

"""Routing helpers for inbound user-attached images.
Two modes:
native — attach images as OpenAI-style ``image_url`` content parts on the
user turn. Provider adapters (Anthropic, Gemini, Bedrock, Codex,
OpenAI chat.completions) already translate these into their
vendor-specific multimodal formats.
text — run ``vision_analyze`` on each image up-front and prepend the
description to the user's text. The model never sees the pixels;
it only sees a lossy text summary. This is the pre-existing
behaviour and still the right choice for non-vision models.
The decision is made once per message turn by :func:`decide_image_input_mode`.
It reads ``agent.image_input_mode`` from config.yaml (``auto`` | ``native``
| ``text``, default ``auto``) and the active model's capability metadata.
In ``auto`` mode:
- If the user has explicitly configured ``auxiliary.vision.provider``
(i.e. not ``auto`` and not empty), we assume they want the text pipeline
regardless of the main model — they've opted in to a specific vision
backend for a reason (cost, quality, local-only, etc.).
- Otherwise, if the active model reports ``supports_vision=True`` in its
models.dev metadata, we attach natively.
- Otherwise (non-vision model, no explicit override), we fall back to text.
This keeps ``vision_analyze`` surfaced as a tool in every session — skills
and agent flows that chain it (browser screenshots, deeper inspection of
URL-referenced images, style-gating loops) keep working. The routing only
affects *how user-attached images on the current turn* are presented to the
main model.

"""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``.

"""Structured logging with steady-state silence for the LSP layer.
The LSP layer fires on every write_file/patch. In a busy session
that's hundreds of events. We want users to be able to ``rg`` the
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
entry would risk re-firing the WARNING/INFO line we explicitly want
to suppress.

"""Auto-installation of LSP server binaries.
Tries to install missing servers using whatever package manager is
appropriate. All installs go to a Hermes-owned bin staging dir,
``<HERMES_HOME>/lsp/bin/``, so we don't pollute the user's global
toolchain.
Strategies:
- ``auto`` — attempt to install with the best available package
manager. This is the default.
- ``manual`` — never install; if a binary is missing, the server is
silently skipped and the user is told about it via ``hermes lsp
status``.
- ``off`` — same as ``manual`` for now (kept distinct so we can
evolve behavior later, e.g. logging differently).
The actual installs happen synchronously the first time a server is
needed and concurrent calls to :func:`try_install` for the same
package are deduplicated via a per-package lock.
Failure modes are non-fatal: every install path is wrapped in
try/except and returns ``None`` on failure. The tool layer then
falls back to its in-process syntax checker, exactly as if the user
hadn't enabled LSP at all.

``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.

"""Workspace and project-root resolution for LSP.
Two concerns live here:
1. **Workspace gate** — the upper-level "is this directory a project?"
check. Hermes only runs LSP when the cwd (or the file being edited)
sits inside a git worktree. Files outside any git root never
trigger LSP, even if a server is configured. This keeps Telegram
gateway users on user-home cwd's from spawning daemons.
2. **NearestRoot** — the per-server project-root walk. Each language
server cares about a different marker (``pyproject.toml`` for
Python, ``Cargo.toml`` for Rust, ``go.mod`` for Go, etc.) and
wants the directory containing that marker. ``nearest_root()``
walks up from a starting path looking for any of a list of marker

"""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.

details: <...>
Known rejection modes documented at
https://forum.moonshot.ai/t/tool-calling-specification-violation-on-moonshot-api/102
and MoonshotAI/kimi-cli#1595:
1. Every property schema must carry a ``type``. Standard JSON Schema allows
type to be omitted (the value is then unconstrained); Moonshot refuses.
2. When ``anyOf`` is used, ``type`` must be on the ``anyOf`` children, not
the parent. Presence of both causes "type should be defined in anyOf
items instead of the parent schema".
The ``#/definitions/...`` → ``#/$defs/...`` rewrite for draft-07 refs is

Nous Portal multiplexes multiple upstream providers (DeepSeek, Kimi,

(a) The caller's own RPM / RPH / TPM / TPH bucket on Nous is
exhausted — a genuine rate limit that will last until the
bucket resets.
(b) The upstream provider is out of capacity for a specific model
— transient, clears in seconds, and has nothing to do with
the caller's quota on Nous.
Tripping the cross-session breaker on (b) blocks ALL Nous requests
(and all models, since Nous is one provider key) for minutes even
though the caller's account is healthy and a different model would
have worked. That's the bug users hit when DeepSeek V4 Pro 429s
trigger a breaker that then blocks Kimi 2.6 and MiMo V2.5 Pro.
We tell the two apart by looking at:
1. The 429 response's own ``x-ratelimit-*`` headers. Nous emits
the full suite on every response including 429s. An exhausted
bucket (``remaining == 0`` with a reset window >= 60s) is
proof of (a).
2. The last-known-good rate-limit state captured by
``_capture_rate_limits()`` on the previous successful
response. If any bucket there was already near-exhausted with
a substantial reset window, the current 429 is almost
certainly (a) continuing from that condition.
If neither signal fires, we treat the 429 as (b): fail the single

"""Centralized Nous Portal request tags.
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.
Tag shape (sent in OpenAI-compatible ``extra_body['tags']``):
[
"product=hermes-agent",
"client=hermes-client-v<__version__>",
]
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
version can change at runtime (editable installs, hot-reload tooling), and
``hermes_cli.__version__`` is the canonical source of truth.

"backend (local/docker/modal/ssh).\n"
"\n"
"## Lifecycle\n"
"\n"
"1. **Orient.** Call `kanban_show()` first (no args — it defaults to your "
"task). The response includes title, body, parent-task handoffs (summary + "
"metadata), any prior attempts on this task if you're a retry, the full "
"comment thread, and a pre-formatted `worker_context` you can treat as "
"ground truth.\n"
"2. **Work inside the workspace.** `cd $HERMES_KANBAN_WORKSPACE` before "
"any file operations. The workspace is yours for this run. Don't modify "
"files outside it unless the task explicitly asks.\n"
"3. **Heartbeat on long operations.** Call `kanban_heartbeat(note=...)` "
"every few minutes during long subprocesses (training, encoding, crawling). "
"Skip heartbeats for short tasks.\n"
"4. **Block on genuine ambiguity.** If you need a human decision you cannot "
"infer (missing credentials, UX choice, paywalled source, peer output you "
"need first), call `kanban_block(reason=\"...\")` and stop. Don't guess. "
"The user will unblock with context and the dispatcher will respawn you.\n"
"5. **Complete with structured handoff.** Call `kanban_complete(summary=..., "
"metadata=...)`. `summary` is 13 human-readable sentences naming concrete "
"artifacts. `metadata` is machine-readable facts "
"(`{changed_files: [...], tests_run: N, decisions: [...]}`). Downstream "
"workers read both via their own `kanban_show`. Never put secrets / "
"tokens / raw PII in either field — run rows are durable forever. "
"Exception: if your output is a code change that needs human review "
"before counting as merged/done (most coding tasks), drop the "
"structured metadata (changed_files / tests_run / diff_path) into a "
"`kanban_comment` first, then end with "

"eyes on it.\n"
"6. **If follow-up work appears, create it; don't do it.** Use "
"`kanban_create(title=..., assignee=<right-profile>, parents=[your-task-id])` "
"to spawn a child task for the appropriate specialist profile instead of "
"scope-creeping into the next thing.\n"
"\n"
"## Orchestrator mode\n"
"\n"
"If your task is itself a decomposition task (e.g. a planner profile given "
"a high-level goal), use `kanban_create` to fan out into child tasks — one "
"per specialist, each with an explicit `assignee` and `parents=[...]` to "

slash-command map (``agent.skill_commands._skill_commands``) reflects

This does NOT invalidate the skills system-prompt cache. Skills are
called by name via ``/skill-name``, ``skills_list``, or ``skill_view``

"""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.

Lifecycle:

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

"""Projects codex app-server events into Hermes' messages list.
The translator that lets Hermes' memory/skill review keep working under the
Codex runtime: it converts Codex `item/*` notifications into the standard
OpenAI-shaped `{role, content, tool_calls, tool_call_id}` entries that
`agent/curator.py` already knows how to read.
Codex emits items with a discriminator field `type`:
- userMessage → {role: "user", content}
- agentMessage → {role: "assistant", content}
- reasoning → stashed in the assistant's "reasoning" field
- commandExecution → assistant tool_call(name="exec") + tool result
- fileChange → assistant tool_call(name="apply_patch") + tool result
- mcpToolCall → assistant tool_call(name=f"mcp.{server}.{tool}") + tool result
- dynamicToolCall → assistant tool_call(name=tool) + tool result
- plan/hookPrompt/collabAgentToolCall → recorded as opaque assistant notes
Each item maps to AT MOST one assistant entry + one tool entry, preserving
Hermes' message-alternation invariants (system → user → assistant → user/tool
→ assistant → ...). Multiple Codex tool calls within one Codex turn produce
multiple consecutive (assistant, tool) pairs, which is the same shape Hermes
already produces for parallel tool calls.

"""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
active and config opts in.

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

Defines the pluggable-backend interface for web search and content extraction.
Providers register instances via ``PluginContext.register_web_search_provider()``;
the active one (selected via ``web.search_backend`` / ``web.extract_backend`` /

This ABC is the SINGLE plugin-facing surface for web providers — every

ABCs were deleted in PR #25182 along with the per-vendor inline helpers
in ``tools/web_tools.py``; the response-shape contract documented below
