teknium1 hit ModuleNotFoundError: No module named 'hermes_bootstrap' after
a code update, on both his Windows machine AND his Linux workstation. The
failure mode is real and affects every user who updates hermes by any path
OTHER than a fully-successful ``hermes update``.
## What happens
hermes_bootstrap.py is a top-level module registered via pyproject.toml's
``py-modules`` list (added by Brooklyn's Windows UTF-8 stdio work). It
must be registered in the venv's editable-install .pth file before Python
can find it as a bare ``import hermes_bootstrap``.
``hermes update`` handles this correctly: (1) git reset --hard, (2) clear
__pycache__, (3) uv pip install -e . (re-registers the package including
the new py-modules list), (4) restart.
BUT if any step AFTER (1) fails — network blip during pip install, PEP 668
on a system Python, venv locked, uv not in PATH, a crash mid-update — the
user is left with new code that references hermes_bootstrap and a venv
that doesn't know about it. Every hermes invocation after that crashes
with ModuleNotFoundError, including ``hermes update`` itself. No recovery
path without manual `uv pip install -e .`.
Also affects users who ``git pull`` the repo directly without running
hermes update — relatively common for developers.
## Fix
Wrap ``import hermes_bootstrap`` in a try/except ModuleNotFoundError
across all 6 entry points (hermes_cli/main, run_agent, gateway/run,
acp_adapter/entry, cli, batch_runner). On Windows, missing bootstrap
means the UTF-8 stdio setup doesn't run — degraded behavior (Unicode
chars may fail to print) but NOT a crash. POSIX is unaffected either way
since the bootstrap is a no-op there.
Once hermes is running again, the user can ``hermes update`` to fully
recover.
## Test update
tests/test_hermes_bootstrap.py::test_entry_point_imports_bootstrap
scans for the first top-level import in each entry point and asserts it
is hermes_bootstrap. Extended the check to accept a Try block whose body
is a lone Import of hermes_bootstrap — that's the recovery-friendly form
we just introduced.
Verified behavior by ``mv hermes_bootstrap.py hermes_bootstrap.py.bak``
and confirming ``python -c "import hermes_cli.main"`` succeeds. 82/82
tests pass (hermes_bootstrap + windows-native + windows-compat).
`hermes uninstall` was POSIX-only. On Windows it would leave four classes
of installer debris behind that the user had to scrub manually:
1. Scheduled Task and/or Startup-folder .cmd entry that installer.ps1
dropped for `hermes gateway install`. Left running at next logon
even after uninstall, pointing at deleted code paths.
2. User-scope PATH entries for the Hermes venv, PortableGit (cmd, bin,
usr\bin), and bundled Node, all written to HKCU\Environment\Path.
3. User-scope env vars HERMES_HOME and HERMES_GIT_BASH_PATH, same
registry key.
4. PortableGit and Node copies under %LOCALAPPDATA%\hermes\ (~200MB),
plus gateway-service/ scratch dir.
Fixes:
- `uninstall_gateway_service()` gets a Windows branch that calls into
`gateway_windows.stop()` + `gateway_windows.uninstall()`, which already
know how to remove both schtasks entries and Startup-folder .cmd files
and how to stop any running detached pythonw gateway.
- `remove_path_from_windows_registry(hermes_home)` reads HKCU\Environment
via winreg, strips any PATH entry whose path-prefix matches the
installer-owned markers (\hermes-agent, \git, \node, \venv under the
current HERMES_HOME), and writes the cleaned value back. Preserves
REG_EXPAND_SZ vs REG_SZ so unexpanded %VARS% in the user's PATH
survive. No PowerShell subprocess, no fragile `reg query` parsing.
- `remove_hermes_env_vars_windows()` deletes HERMES_HOME and
HERMES_GIT_BASH_PATH from the same key.
- `remove_portable_tooling_windows(hermes_home)` rmtree's
`hermes_home/git`, `hermes_home/node`, `hermes_home/gateway-service`
— they're installer artifacts, not user data, so they get removed in
BOTH "keep data" and "full uninstall" modes.
Wired these into `run_uninstall()` guarded by `_is_windows()` so
POSIX paths are untouched. Also fixed the closing "Reload your shell"
footer to point Windows users at opening a new terminal (PATH changes
don't propagate into the current PowerShell session) with the
PowerShell install one-liner instead of bash's curl-pipe.
Verified on Delta-1 (Windows 10) via preview script: correctly
identifies 4 Hermes-installed PATH entries out of 13 total to remove,
leaves Python/LM Studio/ripgrep/ffmpeg/winget entries alone.
## Two residual Windows fixes that were hanging from earlier commits.
### 1. `hermes gateway status` reported 2 PIDs per gateway — TWO bugs compounded
Diagnosed with psutil parent/child walk against live gateway PIDs:
**Bug A (the real one): `_get_parent_pid` silently failed on Windows.**
The helper shelled out to `ps -o ppid= -p <pid>`, which doesn't exist
on Windows — `FileNotFoundError` → returns `None` → the ancestor walk
terminated at `os.getpid()` alone. Consequence: the PID table scan in
`_scan_gateway_pids` couldn't filter out `hermes gateway status`'s own
launcher stub (a venv `pythonw.exe`/`python.exe` that matches the same
`-m hermes_cli.main gateway` pattern as the gateway). Every status
call saw "itself" as a second gateway.
Fix: `_get_parent_pid` now calls `psutil.Process(pid).ppid()` first
(psutil is a core dependency since 3dfb35700) and falls back to `ps`
only when `shutil.which("ps")` succeeds — matching the Windows-footgun
checker's "always guard `ps` / `wmic` / etc. with `shutil.which`" rule.
Before: `Gateway process running (PID: 21952, 46880)` — 46880 changing
on every call (the status invocation's own launcher, which died by the
time the next status call looked).
After (5 consecutive calls):
```
✓ Gateway process running (PID: 21952)
✓ Gateway process running (PID: 21952)
✓ Gateway process running (PID: 21952)
✓ Gateway process running (PID: 21952)
✓ Gateway process running (PID: 21952)
```
Ancestor walk on the fix: 14 PIDs (full chain through bash/explorer)
instead of the broken 1-PID set.
**Bug B (the cosmetic one): venv-launcher dedup.** Standard Windows
CPython venv behaviour is that `<venv>/Scripts/pythonw.exe` is a ~5 MB
launcher stub that spawns the base Python (`C:\\Program Files\\Python311
\\pythonw.exe`) with the same command line and waits. Our process
scanner sees two PIDs for every gateway: launcher + interpreter, same
cmdline. Bug A masked this by accidentally counting the status call
AS one of them; with Bug A fixed, we see both the real launcher and
real interpreter for the gateway process itself.
Fix: `_filter_venv_launcher_stubs` at the tail of `_scan_gateway_pids`
walks each matched PID's ppid via psutil. Any PID that's the PARENT
of another matched PID is a launcher stub — drop it, keep the child.
Scoped to Windows (`is_windows() and len(pids) > 1`) and no-ops when
psutil isn't importable.
Net effect: `gateway status` now reports one PID per gateway — the
interpreter — matching POSIX behaviour and user expectations.
### 2. `install.ps1`: bootstrap pip + auto-install platform SDKs
New `Install-PlatformSdks` function wired between `Invoke-SetupWizard`
and `Start-GatewayIfConfigured`. Fixes two related issues on fresh
Windows installs:
1. The tiered `uv pip install` cascade (introduced in 87fca8342)
correctly falls through when tier 1 `.[all]` fails on the RL git
deps, but the fallback tiers can silently skip SDKs from `[messaging]`
when there's a partial-resolve. Result: user sets `DISCORD_BOT_TOKEN`
in `.env`, fires up gateway, hits "discord module not installed".
2. `uv` creates venvs WITHOUT pip by default, so the user's escape
hatch (`pip install discord.py` in the venv) doesn't exist either.
The new function:
- Skips if `-NoVenv` (nothing to bootstrap into).
- Scans `~/.hermes/.env` for messaging tokens (TELEGRAM_BOT_TOKEN,
DISCORD_BOT_TOKEN, SLACK_BOT_TOKEN, SLACK_APP_TOKEN, WHATSAPP_ENABLED),
filtering placeholder values.
- For each token that's set, runs `python -c "import <sdk>"` to verify.
- If any import fails: runs `python -m ensurepip --upgrade` to bootstrap
pip into the venv (idempotent — no-ops if pip is already present),
then `pip install <spec>` for each missing SDK with specs mirroring
pyproject.toml's `[messaging]` extra to avoid version drift.
The `$ErrorActionPreference = "SilentlyContinue"` spans are not
cosmetic — PowerShell wraps native-stderr from a non-zero-exit
subprocess as a `NativeCommandError` that prints even through
`*> $null` / `2>$null`. Save + restore EAP over the import-probe
and pip-install blocks keeps the output clean.
Verified on this Windows 10 box:
- Initial state: telegram+fastapi+psutil present, discord+slack_sdk
missing (tier 1 `.[all]` had failed — `.tirith-install-failed`
marker in `%LOCALAPPDATA%\\hermes`).
- First run with discord+slack tokens in .env: detects both missing,
ensurepip (skipped — pip was already bootstrapped earlier this
session for telegram), installs `discord.py[voice]==2.7.1` +
`PyNaCl` + `davey`, installs `slack-sdk==3.41.0`. All imports
succeed on verify.
- Second run: all three SDKs report OK, function no-ops.
Pip spec strings mirror pyproject.toml's `[messaging]` extra verbatim
so a bump to the extra picks up here automatically — no drift.
### Files
- `hermes_cli/gateway.py`: `_get_parent_pid` rewritten (psutil-first);
`_filter_venv_launcher_stubs` added; `_scan_gateway_pids` dedups
launchers on Windows when it finds >1 match.
- `scripts/install.ps1`: new `Install-PlatformSdks` function (~85
lines); wired into the main flow at line 1438.
### Verification
- `venv/Scripts/python.exe scripts/check-windows-footguns.py --all`
→ `✓ No Windows footguns found (380 file(s) scanned).`
- `ast.parse` passes on gateway.py.
- `[System.Management.Automation.Language.Parser]::ParseFile` passes
on install.ps1.
- Live gateway (PID 21952, running since 12:33 today) survived 5x
stress loop of `hermes gateway status` without dying.
## Why
Hermes supports Linux, macOS, and native Windows, but the codebase grew up
POSIX-first and has accumulated patterns that silently break (or worse,
silently kill!) on Windows:
- `os.kill(pid, 0)` as a liveness probe — on Windows this maps to
CTRL_C_EVENT and broadcasts Ctrl+C to the target's entire console
process group (bpo-14484, open since 2012).
- `os.killpg` — doesn't exist on Windows at all (AttributeError).
- `os.setsid` / `os.getuid` / `os.geteuid` — same.
- `signal.SIGKILL` / `signal.SIGHUP` / `signal.SIGUSR1` — module-attr
errors at runtime on Windows.
- `open(path)` / `open(path, "r")` without explicit encoding= — inherits
the platform default, which is cp1252/mbcs on Windows (UTF-8 on POSIX),
causing mojibake round-tripping between hosts.
- `wmic` — removed from Windows 10 21H1+.
This commit does three things:
1. Makes `psutil` a core dependency and migrates critical callsites to it.
2. Adds a grep-based CI gate (`scripts/check-windows-footguns.py`) that
blocks new instances of any of the above patterns.
3. Fixes every existing instance in the codebase so the baseline is clean.
## What changed
### 1. psutil as a core dependency (pyproject.toml)
Added `psutil>=5.9.0,<8` to core deps. psutil is the canonical
cross-platform answer for "is this PID alive" and "kill this process
tree" — its `pid_exists()` uses `OpenProcess + GetExitCodeProcess` on
Windows (NOT a signal call), and its `Process.children(recursive=True)`
+ `.kill()` combo replaces `os.killpg()` portably.
### 2. `gateway/status.py::_pid_exists`
Rewrote to call `psutil.pid_exists()` first, falling back to the
hand-rolled ctypes `OpenProcess + WaitForSingleObject` dance on Windows
(and `os.kill(pid, 0)` on POSIX) only if psutil is somehow missing —
e.g. during the scaffold phase of a fresh install before pip finishes.
### 3. `os.killpg` migration to psutil (7 callsites, 5 files)
- `tools/code_execution_tool.py`
- `tools/process_registry.py`
- `tools/tts_tool.py`
- `tools/environments/local.py` (3 sites kept as-is, suppressed with
`# windows-footgun: ok` — the pgid semantics psutil can't replicate,
and the calls are already Windows-guarded at the outer branch)
- `gateway/platforms/whatsapp.py`
### 4. `scripts/check-windows-footguns.py` (NEW, 500 lines)
Grep-based checker with 11 rules covering every Windows cross-platform
footgun we've hit so far:
1. `os.kill(pid, 0)` — the silent killer
2. `os.setsid` without guard
3. `os.killpg` (recommends psutil)
4. `os.getuid` / `os.geteuid` / `os.getgid`
5. `os.fork`
6. `signal.SIGKILL`
7. `signal.SIGHUP/SIGUSR1/SIGUSR2/SIGALRM/SIGCHLD/SIGPIPE/SIGQUIT`
8. `subprocess` shebang script invocation
9. `wmic` without `shutil.which` guard
10. Hardcoded `~/Desktop` (OneDrive trap)
11. `asyncio.add_signal_handler` without try/except
12. `open()` without `encoding=` on text mode
Features:
- Triple-quoted-docstring aware (won't flag prose inside docstrings)
- Trailing-comment aware (won't flag mentions in `# os.kill(pid, 0)` comments)
- Guard-hint aware (skips lines with `hasattr(os, ...)`,
`shutil.which(...)`, `if platform.system() != 'Windows'`, etc.)
- Inline suppression with `# windows-footgun: ok — <reason>`
- `--list` to print all rules with fixes
- `--all` / `--diff <ref>` / staged-files (default) modes
- Scans 380 files in under 2 seconds
### 5. CI integration
A GitHub Actions workflow that runs the checker on every PR and push is
staged at `/tmp/hermes-stash/windows-footguns.yml` — not included in this
commit because the GH token on the push machine lacks `workflow` scope.
A maintainer with `workflow` permissions should add it as
`.github/workflows/windows-footguns.yml` in a follow-up. Content:
```yaml
name: Windows footgun check
on:
push:
branches: [main]
pull_request:
branches: [main]
jobs:

runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: actions/setup-python@v5
with: {python-version: "3.11"}
- run: python scripts/check-windows-footguns.py --all
```
### 6. CONTRIBUTING.md — "Cross-Platform Compatibility" expansion
Expanded from 5 to 16 rules, each with message, example, and fix.
Recommends psutil as the preferred API for PID / process-tree operations.
### 7. Baseline cleanup (91 → 0 findings)
- 14 `open()` sites → added `encoding='utf-8'` (internal logs/caches) or
`encoding='utf-8-sig'` (user-editable files that Notepad may BOM)
- 23 POSIX-only callsites in systemd helpers, pty_bridge, and plugin
tool subprocess management → annotated with
`# windows-footgun: ok — <reason>`
- 7 `os.killpg` sites → migrated to psutil (see §3 above)
## Verification
```
$ python scripts/check-windows-footguns.py --all
✓ No Windows footguns found (380 file(s) scanned).
$ python -c "from gateway.status import _pid_exists; import os
> print('self:', _pid_exists(os.getpid())); print('bogus:', _pid_exists(999999))"
self: True
bogus: False
```
Proof-of-repro that `os.kill(pid, 0)` was actually killing processes
before this fix — see commit `1cbe39914` and bpo-14484. This commit
removes the last hand-rolled ctypes path from the hot liveness-check
path and defers to the best-maintained cross-platform answer.
On Windows, Python's ``os.kill(pid, 0)`` is NOT a no-op. CPython's
implementation (``Modules/posixmodule.c::os_kill_impl``) treats sig=0
as ``CTRL_C_EVENT`` because the two integer values collide at the C
layer, and routes it through ``GenerateConsoleCtrlEvent(0, pid)`` —
which sends a Ctrl+C to the ENTIRE console process group containing
the target PID, not just the PID itself. Any caller that wanted to
check "is PID X alive" via the classic POSIX ``os.kill(pid, 0)``
idiom was silently killing that process (and often unrelated
processes in the same console group) on Windows. Long-standing
Python Windows quirk; see bpo-14484 (open since 2012).
This manifested in Hermes as: every ``hermes gateway status``
invocation would read the gateway's PID from the PID file, call
``os.kill(pid, 0)`` via ``gateway.status.get_running_pid()`` as a
"liveness check", and instantly terminate the gateway it was trying
to report on. No shutdown log, no traceback, no atexit hook fire,
no exit-diag entry — just silent termination of the detached pythonw
process. "Bot answered one message then stopped typing" was the
characteristic end-user symptom because `os.kill(pid, 0)` fires
mid-response-send and kills the gateway between logs.
Reproduction (verified in this branch before the fix):
$ hermes gateway start # gateway alive, PID 37520
$ hermes gateway status # reports "No gateway process detected"
$ tasklist /FI "PID eq 37520" # INFO: No tasks are running
# — gateway terminated silently
Root-cause fix is a new ``gateway.status._pid_exists(pid)`` helper:
- On Windows: Win32 ``OpenProcess(PROCESS_QUERY_LIMITED_INFORMATION |
SYNCHRONIZE, False, pid)`` + ``WaitForSingleObject(handle, 0)``
via ctypes. Zero signal delivery, zero console-group side effects.
Pins ctypes return types to avoid DWORD-vs-signed-int parse bugs
on WAIT_TIMEOUT (0x102). Distinguishes ERROR_INVALID_PARAMETER
(PID gone) from ERROR_ACCESS_DENIED (alive but another user).
- On POSIX: the canonical ``os.kill(pid, 0)`` idiom that actually is
a no-op there.
Then patch every ``os.kill(pid, 0)`` liveness-check callsite to
route through ``_pid_exists`` instead. Total 14 callsites across
11 files; every single one was a latent silent-kill on Windows:
gateway/run.py:2810 — /restart watcher (inline subprocess)
gateway/run.py:15195 — --replace wait loop
gateway/status.py:572 — acquire_gateway_runtime_lock stale check
gateway/status.py:828 — get_running_pid (THE killer for status)
gateway/platforms/whatsapp.py:111
hermes_cli/gateway.py:228, 522, 1012 — gateway-related drain loops
hermes_cli/kanban_db.py:2826 — _pid_alive was claiming to
be cross-platform but used
os.kill(pid, 0) on Windows
hermes_cli/main.py:5792 — CLI process-kill polling
hermes_cli/profiles.py:782 — profile stop wait loop
plugins/google_meet/process_manager.py:74
tools/browser_tool.py:1215, 1255 — browser daemon ownership probes
tools/mcp_tool.py:1255, 3374 — MCP stdio orphan tracking
The watcher source in gateway/run.py:2810 is a multi-line string
that gets spawned as an inline ``python -c "..."`` subprocess, so
it can't import gateway.status. The fix for that callsite inlines
the same ctypes probe directly into the watcher source.
Tested on Windows 10 with the hermes gateway + Telegram bot:
- gateway start → alive
- 5 consecutive ``hermes gateway status`` invocations → gateway
alive after every one, same PID reported each time (37520, 21952)
- gateway.log shows uninterrupted operation; no spurious shutdown
entries; cron ticker and kanban dispatcher still running on
their 60-second cadence
- bot continues answering Telegram messages throughout
Ships alongside an exit-path diagnostic wrapper in
``hermes_cli/gateway.py::run_gateway()`` that captures every way
``asyncio.run(start_gateway(...))`` can return (success, SystemExit,
KeyboardInterrupt, BaseException, atexit) with full traceback to
``logs/gateway-exit-diag.log``. This was used to prove the gateway
was being hard-killed externally (no exit event fired) and should
be kept for future Windows debugging.

Hermes gateway now installs as a real Windows service via
`hermes gateway install`, auto-starts on user logon, and stays running
across reboots. Mirrors the launchd (macOS) / systemd (Linux) contract
so the rest of the CLI dispatcher just plugs into the same `install /
uninstall / start / stop / restart / status` entrypoints.
Primary implementation is the new `hermes_cli/gateway_windows.py`:
- `schtasks /Create /SC ONLOGON /RL LIMITED /RU <user> /NP /IT` creates
a per-user Scheduled Task running as the current user at next logon,
with no UAC prompt and no stored password. Same pattern OpenClaw uses.
- When `schtasks /Create` returns "Access is denied" or times out
(locked-down corporate boxes, 15s/30s hard + no-output cutoffs),
fall back to writing a `.cmd` file into
`%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup\`, which
Windows Explorer fires at every logon. Either path produces the same
end-user experience.
- `_spawn_detached()` launches `pythonw.exe -m hermes_cli.main gateway
run --replace` directly with `DETACHED_PROCESS |
CREATE_NEW_PROCESS_GROUP | CREATE_NO_WINDOW |
CREATE_BREAKAWAY_FROM_JOB` + DEVNULL stdio + sidecar
`logs/gateway-stdio.log`. Going through pythonw.exe (no console)
instead of a cmd.exe shim is what lets the gateway survive the
spawning shell's exit on Windows — documented in
`references/windows-subprocess-sigint-storm.md`.
- Two separate quoting helpers for cmd.exe vs schtasks (`/TR` argument)
— they're different parsers and mixing breaks both. Same split
OpenClaw documents in src/daemon/schtasks.ts.
- `_wait_for_gateway_ready()` + `_report_gateway_start()` poll for a
live gateway process after spawn and report the PID, so install
doesn't lie about success.
Dispatcher wiring in `hermes_cli/gateway.py`:
- `_gateway_command_inner()` gets Windows branches for install /
uninstall / start / stop / restart / status + `_is_service_installed`
+ `_is_service_running`. `gateway status` output + suggested
commands now mention `hermes gateway install` instead of
`sudo hermes gateway install --system` on Windows.
Two separable Windows fixes that only matter for a working
detached gateway, bundled here because shipping them independently
leaves install broken:
(1) Spurious CTRL_C_EVENT on detached pythonw runs. When the gateway
is launched detached on Windows, something on the boot path (HTTPX /
python-telegram-bot / asyncio ProactorEventLoop subprocess plumbing)
synthesizes a Ctrl+C within ~60-90 seconds. Python 3.11 translates it
into KeyboardInterrupt inside `asyncio.run(start_gateway(...))`, the
outer `except KeyboardInterrupt: return` exits cleanly, and the
process dies with no shutdown log — "bot started typing, then
stopped" is the fingerprint because the interrupt fires mid-send.
Fix in `run_gateway()`: when `is_windows()` and stdin is not a TTY,
install `signal.signal(SIGINT, SIG_IGN)` + same for SIGBREAK. Real
console runs have a TTY and skip the absorber, so user Ctrl+C still
works interactively. Same family as commit 449ad952b's browser-tool
SIGINT absorber; cross-referenced in the ref doc.
(2) `wmic process get` is the process-list path used by
`_scan_gateway_pids()` / `find_gateway_pids()`, which power status,
stop, and restart on Windows. `C:\Windows\System32\wbem\WMIC.exe` has
been deprecated since Windows 10 21H1 and is not installed on modern
Win 10/11 boxes, so `find_gateway_pids()` silently returns [] — status
sees no gateway even when one is running. Fix: `shutil.which("wmic")`
first, fall back to PowerShell's `Get-CimInstance Win32_Process`
emitting the same LIST-style `CommandLine=...` / `ProcessId=...` pairs
the downstream parser already handles. Zero behavior change on boxes
where wmic still works.
Verified end-to-end on Windows 10 (Delta-1):
- `hermes gateway install` → falls back to Startup folder (access
denied on schtasks for this user) + detached pythonw spawn, PID
reported correctly.
- Gateway connects to Telegram, answers messages, stays alive past
2min (previously died at ~85s with no shutdown log).
- `hermes gateway stop` + `uninstall` both clean up both tracks.

Replace hardcoded ~/.hermes/shared/ references with
get_default_hermes_root() / 'shared' so the cross-profile Nous auth
store lands in the correct location on every platform:
- Linux/macOS: ~/.hermes/shared/
- native Windows: %LOCALAPPDATA%\hermes\shared- Docker / custom HERMES_HOME: <root>/shared/
Updates _nous_shared_auth_dir(), the pytest seat-belt in
_nous_shared_store_path(), and the auth_add_command comment to match.
Previously Windows installs wrote to ~/.hermes/shared/ even though the
rest of the CLI uses %LOCALAPPDATA%\hermes, so profiles couldn't see
each other's shared credential.
scripts/install.sh runs 'npx playwright install --with-deps chromium'
on every Linux distro after the npm-install step, which is why browser
tools Just Work on Linux. scripts/install.ps1 never did the equivalent
step, so on native Windows installs check_browser_requirements() in
tools/browser_tool.py would return False (no Chromium under
%LOCALAPPDATA%\ms-playwright) and every browser_* tool got silently
filtered out of the agent's tool schema — no error, no log entry, user
just wondered why the tools didn't exist.
Two-part fix:
1. scripts/install.ps1: after 'npm install' in InstallDir succeeds, run
'npx playwright install chromium'. Resolves npx via the same
execution-policy-aware logic already used for npm (prefer npx.cmd
next to npmExe, fall back to Get-Command). Surfaces a warning +
manual-recovery hint when the install fails, matching install.sh
behaviour for distros.
2. hermes_cli/doctor.py: after the agent-browser check, lazily import
tools.browser_tool and reuse the exact same _chromium_installed()
predicate check_browser_requirements() uses, so the doctor signal
cannot drift from the runtime gate. Skip the check when Camofox /
CDP override / a cloud provider / Lightpanda is configured (those
bypass local Chromium). On missing Chromium, the hint is
platform-correct: '--with-deps' on POSIX, plain 'install chromium'
on win32.
Verified on Windows 10:
- 'npx playwright install chromium' completes successfully, drops
Chrome Headless Shell under %LOCALAPPDATA%\ms-playwright
- check_browser_requirements() flips from False -> True
- 'hermes doctor' now prints either '✓ Playwright Chromium (browser
engine)' or '⚠ Playwright Chromium not installed' + fix command
- tests/hermes_cli/test_doctor.py: 38/38 pass
- tests/tools/test_browser_chromium_check.py: 16/16 pass
Windows Terminal intercepts Alt+Enter for its fullscreen shortcut, leaving
Windows users with no Enter-involving way to insert a newline in the Hermes
prompt. Fix it by reclaiming c-j on Windows only:
- _bind_prompt_submit_keys now binds c-j (LF) to submit only on POSIX, where
thin PTYs (docker exec, some SSH configs) deliver Enter as LF. On Windows
plain Enter is always c-m, so c-j is free.
- Windows-only prompt binding: c-j inserts a newline. Windows Terminal sends
Ctrl+Enter as LF, so the user-facing keystroke is Ctrl+Enter — no terminal
settings changes required.
- Alt+Enter binding unchanged; still works on mac/Linux/WSL.
- Test TestPromptToolkitTerminalCompatibility::test_lf_enter_binds_to_submit_handler
split into platform-aware assertions for POSIX vs win32.
- Fixed the Ctrl+J claim in hermes_cli/tips.py (was wrong before this commit
even on POSIX) to point Windows users at Ctrl+Enter.
Tradeoff: on Windows, raw Ctrl+J (without Enter) also inserts a newline,
since WT collapses Ctrl+Enter and Ctrl+J to the same c-j keycode. No
conflicting Hermes binding existed for Ctrl+J, so this is a harmless side
effect.
Closes the last Python-on-Windows UTF-8 exposure by making every
text-mode open() call explicit about its encoding.
Before: on Windows, bare open(path, 'r') defaults to the system
locale encoding (cp1252 on US-locale installs). That means reading
any config/yaml/markdown/json file with non-ASCII content either
crashes with UnicodeDecodeError or silently mis-decodes bytes.
After: all 89 affected call sites in production code now pass
encoding='utf-8' explicitly. Works identically on every platform
and every locale, no surprise behavior.
Mechanical sweep via:
ruff check --preview --extend-select PLW1514 --unsafe-fixes --fix --exclude 'tests,venv,.venv,node_modules,website,optional-skills, skills,tinker-atropos,plugins' .
All 89 fixes have the same shape: open(x) or open(x, mode) became
open(x, encoding='utf-8') or open(x, mode, encoding='utf-8'). Nothing
else changed. Every modified file still parses and the Windows/sandbox
test suite is still green (85 passed, 14 skipped, 0 failed across
tests/tools/test_code_execution_windows_env.py +
tests/tools/test_code_execution_modes.py + tests/tools/test_env_passthrough.py +
tests/test_hermes_bootstrap.py).
Scope notes:
- tests/ excluded: test fixtures can use locale encoding intentionally
(exercising edge cases). If we want to tighten tests later that's
a separate PR.
- plugins/ excluded: plugin-specific conventions may differ; plugin
authors own their code.
- optional-skills/ and skills/ excluded: skill scripts are user-authored
and we don't want to mass-edit them.
- website/ and tinker-atropos/ excluded: vendored / generated content.
46 files touched, 89 +/- lines (symmetric replacement). No behavior
change on POSIX or on Windows when the file is ASCII; bug fix on
Windows when the file contains non-ASCII.
Codebase-wide fix for Python-on-Windows UTF-8 footguns, complementing
the earlier execute_code sandbox fixes (which remain load-bearing for
when the sandbox explicitly scrubs child env).
Problem: Python on Windows has two long-standing text-encoding pitfalls:
1. sys.stdout/stderr are bound to the console code page (cp1252 on
US-locale installs) — print('café') crashes with UnicodeEncodeError.
2. Subprocess children don't know to use UTF-8 unless PYTHONUTF8 and/or
PYTHONIOENCODING are set in their env — so any Python we spawn
(linters, sandbox children, delegation workers) hits the same bug.
Solution: A tiny bootstrap module (hermes_bootstrap.py) imported as the
first statement of every Hermes entry point:
- hermes_cli/main.py (hermes / hermes-agent console_script)
- run_agent.py (hermes-agent direct)
- acp_adapter/entry.py (hermes-acp)
- gateway/run.py (messaging gateway)
- batch_runner.py (parallel batch mode)
- cli.py (legacy direct-launch CLI)
On Windows, the bootstrap:
- os.environ.setdefault('PYTHONUTF8', '1') (PEP 540 UTF-8 mode)
- os.environ.setdefault('PYTHONIOENCODING', 'utf-8')
- sys.stdout/stderr/stdin.reconfigure(encoding='utf-8', errors='replace')
Children inherit the env vars → they run in UTF-8 mode.
Current process's stdio is reconfigured → print('café') works now.
On POSIX (Linux/macOS), the bootstrap is a complete no-op. We don't
touch LANG, LC_*, or anything else — users who have intentionally
configured a non-UTF-8 locale aren't affected. POSIX systems are
already UTF-8 by default in 99% of modern setups, so there's nothing
to fix.
setdefault() (not overwrite) means users who explicitly set PYTHONUTF8=0
or PYTHONIOENCODING=cp1252 in their environment are respected.
What this does NOT fix: bare open(path, 'w') calls in the *parent*
process still default to locale encoding because PYTHONUTF8 is only
read at interpreter init. A ruff PLW1514 sweep (separate follow-up)
will add explicit encoding='utf-8' at those ~219 call sites for
belt-and-suspenders.
Tests (17): 16 passed, 1 skipped on Windows.
- Windows: env vars set, stdio reconfigured, child inherits UTF-8 mode
- POSIX: complete no-op (verified on fake POSIX + skipped on real
POSIX since we don't have a Linux box in this session)
- Idempotence: multiple calls safe
- Graceful degradation: non-reconfigurable streams don't crash
- User opt-out: explicit PYTHONUTF8=0 is respected
- Load order: every entry point's FIRST top-level import is
hermes_bootstrap, enforced by an AST-level parametrized test
pyproject.toml: added hermes_bootstrap to py-modules so it ships with
pip installs.
Two fixes from teknium1's next install run:
1. **npm install: "npm.ps1 cannot be loaded because running scripts is
disabled on this system."** Get-Command's default PATHEXT ordering
picked up ``npm.ps1`` (the PowerShell shim) ahead of ``npm.cmd`` (the
batch shim). Most Windows users have PowerShell's execution policy
set to Restricted or RemoteSigned, which blocks unsigned ``.ps1``
files. ``npm.cmd`` has no such restriction and works universally.
Install-NodeDeps now detects when Get-Command returned npm.ps1, looks
for a sibling npm.cmd in the same directory, and prefers it. Prints
an info line so the user sees why. Emits a warning + hint if only
npm.ps1 is available.
2. **"Launch hermes chat now? Y" crashes with "%1 is not a valid Win32
application" on Windows installs.** The setup wizard calls
``relaunch(["chat"])``; ``resolve_hermes_bin()`` returned
``sys.argv[0]`` which was ``...\\hermes_cli\\main.py`` (because hermes
was launched via ``python -m hermes_cli.main`` during setup).
On Windows, ``os.access(script.py, os.X_OK)`` returns True because
PATHEXT lists ``.py`` when the Python launcher is registered — but
``subprocess.run([script.py, ...])`` can't actually execute a ``.py``
directly. CreateProcessW needs a real PE file.
Fixed ``resolve_hermes_bin`` to reject ``.py``/``.pyc`` argv0 values
on Windows specifically. Falls through to ``shutil.which("hermes")``
(hermes.exe in the venv Scripts dir) or, as a final fallback, lets
build_relaunch_argv build ``[sys.executable, "-m", "hermes_cli.main"]``
which is bulletproof. POSIX behaviour unchanged — ``.py`` argv0 with
a shebang + chmod+x is still a valid exec target there.
3 new tests cover the Windows paths: .py argv0 + hermes.exe on PATH →
returns hermes.exe; .py argv0 + no PATH → returns None (caller uses
python -m); POSIX + executable .py → still accepted.
26 relaunch tests pass, no POSIX regressions.
Three interrelated bugs from teknium1's first interactive chat on Windows:
1. **Snapshot/cwd file paths unquoted in bash command strings.** The session
bootstrap and per-command wrapper interpolated
``self._snapshot_path`` / ``self._cwd_file`` unquoted into bash commands
like ``export -p > C:/Users/ryanc/.../hermes-snap-xxx.sh``. Git Bash's
MSYS2 layer handles ``C:/...`` paths correctly ONLY when quoted; unquoted,
the colon and forward-slash get glob-parsed and the redirect targets a
bogus path. Symptom: every terminal command emitted two
``C:/Users/.../hermes-snap-*.sh (No such file or directory)`` lines that
bled into stdout (``stderr=STDOUT`` on the local backend) and corrupted
file contents when the agent wrote to scratch paths via the terminal
tool. Fix: ``shlex.quote()`` every interpolation of ``_snapshot_path``
and ``_cwd_file`` in base.py — no-op on POSIX (the paths contain no
shell-metachars), critical on Windows.
2. **Stale PATH on first hermes launch after install.** ``install.ps1``
adds the PortableGit ``cmd`` / ``bin`` / ``usr\bin`` directories to the
Windows **User** PATH via ``SetEnvironmentVariable(..., "User")``. That
write propagates to newly *spawned* processes only — already-running
shells (including the one the user types ``hermes`` into immediately
after install) retain their old PATH. So hermes starts with a PATH that
doesn't include bash, rg, grep, ssh — and ``search_files`` reports
"rg/find not available" when the user clearly just installed them.
Fix: new ``_augment_path_with_known_tools()`` helper called from
``configure_windows_stdio()`` on startup. Prepends the Hermes-managed
Git directories + the WinGet Links directory (where ripgrep lands) to
``os.environ['PATH']`` if they exist on disk but aren't already in
PATH. Subsequent subprocess calls (including bash spawns via
``_find_bash()``) inherit the augmented PATH and find everything.
No-op on POSIX and when the directories don't exist.
3. **Root cause of "file content corruption".** #1 was the proximate cause.
Errors like ``C:/Users/.../hermes-snap-xxx.sh: No such file or directory``
were emitted on stderr by the failed redirect, captured into stdout via
``stderr=subprocess.STDOUT``, and if the agent used terminal commands
like ``cat > file`` the leaked error bytes became part of the file.
Fixing #1 eliminates this entirely.
## Tests
All 77 Windows-compat tests still pass on Linux (POSIX path is
shlex.quote('/tmp/foo.sh') → '/tmp/foo.sh' — unchanged).
## Not addressed here (would need a bigger design)
- Python file tools (``write_file``, ``read_file``) and the bash-backed
terminal tool see DIFFERENT views of ``/tmp`` on Windows. Python treats
``/tmp`` as ``C:\tmp`` (drive-relative), Git Bash's MSYS2 treats it as
a virtual mount to the PortableGit install's ``tmp\``. Would need a
translation shim in the Python tools to resolve bash-virtual paths to
their native-Windows equivalents. Workaround for users today: use
absolute native paths (``C:\Users\you\...``) instead of ``/tmp/...``
when crossing between terminal and Python file tools.
Three real bugs from teknium1's first Windows install run:
1. **MinGit has no bash.exe.** MinGit is the minimal-automation Git for Windows
distribution — it ships git.exe but deliberately strips bash and the POSIX
coreutils. Installer logged "Could not locate bash.exe" and Hermes would
fail to run any shell command. Switched to PortableGit — the full Git for
Windows minus the installer UI. PortableGit ships bash.exe at
<root>\bin\bash.exe plus sh, awk, sed, grep, curl, ssh in usr\bin\. ARM64
variant is detected separately (PortableGit-*-arm64.7z.exe). 32-bit falls
back to MinGit-32-bit with a warning (PortableGit is 64-bit only).
PortableGit ships as a 7z self-extractor (56MB vs MinGit's 38MB). We
invoke it with `-o<target> -y` to extract silently — no 7z install needed,
it's self-contained.
Updated tools/environments/local.py::_find_bash candidate order to prefer
the PortableGit layout (<root>\bin\bash.exe) with the MinGit layout
(<root>\usr\bin\bash.exe) as a fallback so existing installs keep working.
2. **os.execvp "Exec format error" on Windows.** Setup wizard's "Launch
hermes chat now? Y" called `os.execvp(["hermes", "chat"])` which on
Windows can only swap to real Win32 .exe files — chokes with OSError(8)
on .cmd batch shims and Python console-script wrappers. Added a
win32 branch in hermes_cli/relaunch.py::relaunch() that uses
subprocess.run + sys.exit — functionally identical (user sees "hermes
exited, then new hermes started") with one extra PID in play. POSIX
path is UNCHANGED — still uses os.execvp for in-place replacement.
Catches OSError in the Windows branch and surfaces a "open a new
terminal so PATH picks up, then re-run hermes" hint instead of a
cryptic traceback.
3. **npm install failures silent on Windows.** The install.ps1 was invoking
`npm install --silent 2>&1 | Out-Null` inside a try/catch. PowerShell's
try/catch does NOT trigger on non-zero process exit codes — only on
unhandled .NET exceptions — so npm failing printed a generic "npm
install failed" with zero information about WHY. The silent pipe ate
the stderr.
Rewrote Install-NodeDeps to:
- Resolve npm.cmd via Get-Command (respects PATHEXT) instead of
relying on bare `npm` name resolution.
- Use Start-Process with -PassThru to capture the actual exit code.
- Redirect stderr to a temp log and surface the first ~800 chars of
the real npm error when install fails, plus the log path for the
full text.
- Fail loudly with the right exit code instead of a misleading success.
- Bail cleanly with a helpful message when npm isn't on PATH at all.
4. **"True" printing to console after Node check.** `Test-Node` returns $true;
installer called it as a bare statement (no assignment, no cast). PowerShell
prints bare return values. Wrapped the call in `[void](Test-Node)`.
## Tests
- Added 3 new tests in tests/hermes_cli/test_relaunch.py covering the
Windows branch: subprocess is called (not execvp), child exit code
propagates, OSError surfaces a helpful message. All 23 tests pass
(20 existing + 3 new).
- 77 Windows-compat tests still pass, POSIX behaviour unchanged.
Second pass on native Windows support, driven by a systematic audit across
five areas: POSIX-only primitives (signal.SIGKILL/SIGHUP/SIGPIPE, os.WNOHANG,
os.setsid), path translation bugs (/c/Users → C:\Users), subprocess patterns
(npm.cmd batch shims, start_new_session no-op on Windows), subsystem health
(cron, gateway daemon, update flow), and module-level import guards.
Every change is platform-gated — POSIX (Linux/macOS) behaviour is preserved
bit-identical. Explicit "do no harm" test: test_posix_path_preserved_on_linux,
test_posix_noop, test_windows_detach_popen_kwargs_is_posix_equivalent_on_posix.
## New module
- hermes_cli/_subprocess_compat.py — shared helpers (resolve_node_command,
windows_detach_flags, windows_hide_flags, windows_detach_popen_kwargs).
All no-ops on non-Windows.
## CRITICAL fixes (would crash or silently break on Windows)
- tui_gateway/entry.py: SIGPIPE/SIGHUP referenced at module top level would
AttributeError on import on Windows, breaking `hermes --tui` entirely (it
spawns this module as a subprocess). Guard each signal.signal() call with
hasattr() and add SIGBREAK as Windows' SIGHUP equivalent.
- hermes_cli/kanban_db.py: os.waitpid(-1, os.WNOHANG) in dispatcher tick was
unguarded. os.WNOHANG doesn't exist on Windows. Gate the whole reap loop
behind `os.name != "nt"` — Windows has no zombies anyway.
- tools/code_execution_tool.py: AF_UNIX socket for execute_code RPC fails on
most Windows builds. Fall back to loopback TCP (AF_INET on 127.0.0.1:0
ephemeral port) when _IS_WINDOWS. HERMES_RPC_SOCKET env var now accepts
either a filesystem path (POSIX) or `tcp://127.0.0.1:<port>` (Windows).
Generated sandbox client parses both.
- cron/scheduler.py: `argv = ["/bin/bash", str(path)]` hardcoded. Use
shutil.which("bash") so Windows (Git Bash via MinGit) works, with a
readable error when bash is genuinely absent.
- 6 bare npm/npx spawn sites: tools_config.py x2, doctor.py, whatsapp.py
(npm install + node version probe), browser_tool.py x2. On Windows npm
is npm.cmd / npx is npx.cmd (batch shims); subprocess.Popen(["npm", ...])
fails with WinError 193. shutil.which(...) returns the absolute .cmd
path which CreateProcessW accepts because the extension routes through
cmd.exe /c. POSIX behaviour unchanged (shutil.which still returns the
same path subprocess would resolve itself).
## HIGH fixes (silent misbehaviour on Windows)
- tools/environments/local.py get_temp_dir: hardcoded /tmp returned on
Windows meant `_cwd_file = "/tmp/hermes-cwd-*.txt"`, which bash wrote
via MSYS2's virtual /tmp but native Python couldn't open. Result: cwd
tracking silently broken — `cd` in terminal tool did nothing. Windows
branch now returns `%HERMES_HOME%/cache/terminal` with forward slashes
(works in both bash and Python, guaranteed no spaces).
- tools/environments/local.py _make_run_env PATH injection: `/usr/bin not
in split(":")` heuristic mangles Windows PATH (";" separator). Gate
the injection behind `not _IS_WINDOWS`.
- hermes_cli/gateway.py launch_detached_profile_gateway_restart: outer
Popen + watcher-script Popen both used start_new_session=True, which
Windows silently ignores. Watcher stayed attached to CLI's console,
died when user closed terminal after `hermes update`, left gateway
stale. Now branches through windows_detach_popen_kwargs() helper
(CREATE_NEW_PROCESS_GROUP | DETACHED_PROCESS | CREATE_NO_WINDOW on
Windows, start_new_session=True on POSIX — identical to main).
## MEDIUM fixes
- gateway/run.py /restart and /update handlers: hardcoded bash/setsid
chain crashes on Windows when user triggers /update in-gateway. Now
has sys.platform=="win32" branch using sys.executable + a tiny
Python watcher with proper detach flags. POSIX path is unchanged.
- cli.py _git_repo_root: Git on Windows sometimes returns /c/Users/...
style paths that break subprocess.Popen(cwd=...) and Path().resolve().
Added _normalize_git_bash_path() helper that translates /c/Users,
/cygdrive/c, /mnt/c variants to native C:\Users form. POSIX no-op.
_git_repo_root() now routes every result through it.
- cli.py worktree .worktreeinclude: os.symlink on directories failed
hard on Windows (requires admin or Developer Mode). Falls back to
shutil.copytree with a warning log.
## Tests
- 29 new tests in tests/tools/test_windows_native_support.py covering:
subprocess_compat helpers, TUI entry signal guards, kanban waitpid
guard, code_execution TCP fallback source-level invariants, cron bash
resolution, npm/npx bare-spawn lint per-file, local env Windows temp
dir, PATH injection gating, git bash path normalization, symlink
fallback, gateway detached watcher flags.
- One existing test assertion adjusted in test_browser_homebrew_paths:
it compared captured Popen argv to the BARE `"npx"` literal; after the
shutil.which() change argv[0] is the absolute path. New assertion
checks the shape (two items, second is `agent-browser`) rather than
the exact first-item string. Behaviour unchanged; test was too strict.
All 56 tests pass on Linux (30 from previous commits + 26 new).
267 tests from the affected files/dirs (browser, code_exec, local_env,
process_registry, kanban_db, windows_compat) all pass — zero regressions.
tests/hermes_cli/ (3909 pass) and tests/gateway/ (5021 pass) unchanged;
all pre-existing test failures confirmed unrelated via `git stash` re-run.
## What's still deferred (LOW priority)
- Visible cmd-window flashes on short-lived console apps (~14 sites) —
cosmetic, needs a follow-up pass once we have user reports.
- agent/file_safety.py POSIX-only security deny patterns — separate
hardening task.
- tools/process_registry.py returning "/tmp" as fallback — theoretical;
reachable only when all env-var candidates fail.
Pre-existing Windows bug surfaced while reviewing the portable-MinGit
install: prompt_toolkit's Buffer.open_in_editor() falls back to POSIX
absolute paths (/usr/bin/nano, /usr/bin/vi, /usr/bin/emacs) that don't
exist on native Windows. When neither $EDITOR nor $VISUAL is set,
Ctrl+X Ctrl+E ("open prompt in editor") and /edit both silently do
nothing on Windows — the user hits the key, nothing happens, no error.
This wasn't caused by MinGit (full Git for Windows doesn't fix it either,
because the Windows Python subprocess call resolves `/usr/bin/nano` as
`C:\usr\bin\nano`, which doesn't exist even with nano installed).
Fixes:
- hermes_cli/stdio.py::configure_windows_stdio now sets EDITOR=notepad
on Windows if neither EDITOR nor VISUAL is set. notepad.exe is in
every Windows install, works as a blocking editor (subprocess.call
waits for the window to close), and writes back to the file.
- hermes_cli/config.py (hermes config edit): reorder fallback list so
Windows tries notepad first — previously nano led the list, which
required Git Bash / WSL to be in PATH.
- Users who want VSCode / Neovim / Notepad++ can still override via
$env:EDITOR — that's checked before our default kicks in. Docstring
spells out the common overrides.
The Ink TUI (`hermes --tui`) already handled Windows correctly via
ui-tui/src/lib/editor.ts falling back to notepad.exe on win32 — this
commit brings the classic prompt_toolkit CLI into parity.
3 new tests in test_windows_native_support.py verify:
- EDITOR=notepad gets set when unset on Windows
- Explicit $EDITOR is respected
- $VISUAL is respected (not overwritten by our default)
Native Windows (with Git for Windows installed) can now run the Hermes CLI
and gateway end-to-end without crashing. install.ps1 already existed and
the Git Bash terminal backend was already wired up — this PR fills the
remaining gaps discovered by auditing every Windows-unsafe primitive
(`signal.SIGKILL`, `os.kill(pid, 0)` probes, bare `fcntl`/`termios`
imports) and by comparing hermes against how Claude Code, OpenCode, Codex,
and Cline handle native Windows.
## What changed
### UTF-8 stdio (new module)
- `hermes_cli/stdio.py` — single `configure_windows_stdio()` entry point.
Flips the console code page to CP_UTF8 (65001), reconfigures
`sys.stdout`/`stderr`/`stdin` to UTF-8, sets `PYTHONIOENCODING` + `PYTHONUTF8`
for subprocesses. No-op on non-Windows. Opt out via `HERMES_DISABLE_WINDOWS_UTF8=1`.
- Called early in `cli.py::main`, `hermes_cli/main.py::main`, and
`gateway/run.py::main` so Unicode banners (box-drawing, geometric
symbols, non-Latin chat text) don't `UnicodeEncodeError` on cp1252
consoles.
### Crash sites fixed
- `hermes_cli/main.py:7970` (hermes update → stuck gateway sweep): raw
`os.kill(pid, _signal.SIGKILL)` → `gateway.status.terminate_pid(pid, force=True)`
which routes through `taskkill /T /F` on Windows.
- `hermes_cli/profiles.py::_stop_gateway_process`: same fix — also
converted SIGTERM path to `terminate_pid()` and widened OSError catch
on the intermediate `os.kill(pid, 0)` probe.
- `hermes_cli/kanban_db.py:2914, 3041`: raw `signal.SIGKILL` →
`getattr(signal, "SIGKILL", signal.SIGTERM)` fallback (matches the
pattern already used in `gateway/status.py`).
### OSError widening on `os.kill(pid, 0)` probes
Windows raises `OSError` (WinError 87) for a gone PID instead of
`ProcessLookupError`. Widened the catch at:
- `gateway/run.py:15101` (`--replace` wait-for-exit loop — without this,
the loop busy-spins the full 10s every Windows gateway start)
- `hermes_cli/gateway.py:228, 460, 940`
- `hermes_cli/profiles.py:777`
- `tools/process_registry.py::_is_host_pid_alive`
- `tools/browser_tool.py:1170, 1206`
### Dashboard PTY graceful degradation
`hermes_cli/pty_bridge.py` depends on `fcntl`/`termios`/`ptyprocess`,
none of which exist on native Windows. Previously a Windows dashboard
would crash on `import hermes_cli.web_server` because of a top-level
import. Now:
- `hermes_cli/web_server.py` wraps the pty_bridge import in
`try/except ImportError` and sets `_PTY_BRIDGE_AVAILABLE=False`.
- The `/api/pty` WebSocket handler returns a friendly "use WSL2 for
this tab" message instead of exploding.
- Every other dashboard feature (sessions, jobs, metrics, config
editor) runs natively on Windows.
### Dependency
- `pyproject.toml`: add `tzdata>=2023.3; sys_platform == 'win32'` so
Python's `zoneinfo` works on Windows (which has no IANA tzdata
shipped with the OS). Credits @sprmn24 (PR #13182).
### Docs
- README.md: removed "Native Windows is not supported"; added
PowerShell one-liner and Git-for-Windows prerequisite note.
- `website/docs/getting-started/installation.md`: new Windows section
with capability matrix (everything native except the dashboard
`/chat` PTY tab, which is WSL2-only).
- `website/docs/user-guide/windows-wsl-quickstart.md`: reframed as
"WSL2 as an alternative to native" rather than "the only way".
- `website/docs/developer-guide/contributing.md`: updated
cross-platform guidance with the `signal.SIGKILL` / `OSError`
rules we enforce now.
- `website/docs/user-guide/features/web-dashboard.md`: acknowledged
native Windows works for everything except the embedded PTY pane.
## Why this shape
Pulled from a survey of how other agent codebases handle native
Windows (Claude Code, OpenCode, Codex, Cline):
- All four treat Git Bash as the canonical shell on Windows, same as
hermes already does in `tools/environments/local.py::_find_bash()`.
- None of them force `SetConsoleOutputCP` — but they don't have to,
Node/Rust write UTF-16 to the Win32 console API. Python does not get
that for free, so we flip CP_UTF8 via ctypes.
- None of them ship PowerShell-as-primary-shell (Claude Code exposes
PS as a secondary tool; scope creep for this PR).
- All of them use `taskkill /T /F` for force-kill on Windows, which
is exactly what `gateway.status.terminate_pid(force=True)` does.
## Non-goals (deliberate scope limits)
- No PowerShell-as-a-second-shell tool — worth designing separately.
- No terminal routing rewrite (#12317, #15461, #19800 cluster) — that's
the hardest design call and needs a separate doc.
- No wholesale `open()` → `open(..., encoding="utf-8")` sweep (Tianworld
cluster) — will do as follow-up if users hit actual breakage; most
modern code already specifies it.
## Validation
- 28 new tests in `tests/tools/test_windows_native_support.py` — all
platform-mocked, pass on Linux CI. Cover:
- `configure_windows_stdio` idempotency, opt-out, env-preservation
- `terminate_pid` taskkill routing, failure → OSError, FileNotFoundError fallback
- `getattr(signal, "SIGKILL", …)` fallback shape
- `_is_host_pid_alive` OSError widening (Windows-gone-PID behavior)
- Source-level checks that all entry points call `configure_windows_stdio`
- pty_bridge import-guard present in `web_server.py`
- README no longer says "not supported"
- 12 pre-existing tests in `tests/tools/test_windows_compat.py` still pass.
- `tests/hermes_cli/` ran fully (3909 passed, 9 failures — all confirmed
pre-existing on main by stash-test).
- `tests/gateway/` ran fully (5021 passed, 1 pre-existing failure).
- `tests/tools/test_process_registry.py` + `test_browser_*` pass.
- Manual smoke: `import hermes_cli.stdio; import gateway.run;
import hermes_cli.web_server` — all clean, `_PTY_BRIDGE_AVAILABLE=True`
on Linux (as expected).

_distribution_metadata() reads the profile's distribution.yaml without
an explicit encoding, which defaults to the platform's locale encoding
— UTF-8 on POSIX, cp1252/mbcs on Windows. Files round-tripped between
hosts get mojibake on the Windows side.
Single-line fix: add encoding='utf-8' to the open() call. Matches the
sibling _read_config_model() site at line 398, which already does this.
Surfaces once PR #21561 lands the blocking ruff-check CI job
(PLW1514 — unspecified-encoding), but the underlying bug is
pre-existing on main.
Third slice of the Microsoft Teams meeting pipeline stack, salvaged
onto current main. Adds the standalone teams_pipeline plugin that
consumes Graph change notifications from the webhook listener,
resolves meeting artifacts (transcript first, recording + STT fallback
later), persists job state in a durable store, and exposes an operator
CLI for inspection, replay, subscription management, and validation.
Design choices follow maintainer review feedback on PR #19815:
- Standalone plugin rather than bolted-on core surface
(plugins/teams_pipeline/, kind: standalone in plugin.yaml).
- Zero new model tools. The agent drives the pipeline by invoking
the operator CLI via the terminal tool, guided by the skill that
ships with a follow-up PR.
- Reuses the existing msgraph_webhook gateway platform for Graph
ingress. Pipeline runtime is wired in via bind_gateway_runtime and
gated on plugins.enabled so gateways that don't run the plugin
boot cleanly.
Additions:
- plugins/teams_pipeline/: runtime (gateway wiring + config builder),
pipeline core, durable SQLite store, subscription maintenance
helpers, Graph artifact resolution, operator CLI (list, show,
run/replay, fetch dry-run, subscriptions list, subscribe,
renew-subscription, delete-subscription, maintain-subscriptions,
token-health, validate).
- hermes_cli/main.py: second-pass plugin CLI discovery so any
standalone plugin registered via ctx.register_cli_command()
outside the memory-plugin convention path gets its subcommand
wired into argparse without touching core.
- gateway/run.py: _teams_pipeline_plugin_enabled() config gate,
_wire_teams_pipeline_runtime() binding after adapter setup, and
the two runner attributes used by the runtime.

Background macOS desktop control via cua-driver MCP — does NOT steal the
user's cursor or keyboard focus, works with any tool-capable model.
Replaces the Anthropic-native `computer_20251124` approach from the
abandoned #4562 with a generic OpenAI function-calling schema plus SOM
(set-of-mark) captures so Claude, GPT, Gemini, and open models can all
drive the desktop via numbered element indices.
- `tools/computer_use/` package — swappable ComputerUseBackend ABC +
CuaDriverBackend (stdio MCP client to trycua/cua's cua-driver binary).
- Universal `computer_use` tool with one schema for all providers.
Actions: capture (som/vision/ax), click, double_click, right_click,
middle_click, drag, scroll, type, key, wait, list_apps, focus_app.
- Multimodal tool-result envelope (`_multimodal=True`, OpenAI-style
`content: [text, image_url]` parts) that flows through
handle_function_call into the tool message. Anthropic adapter converts
into native `tool_result` image blocks; OpenAI-compatible providers
get the parts list directly.
- Image eviction in convert_messages_to_anthropic: only the 3 most
recent screenshots carry real image data; older ones become text
placeholders to cap per-turn token cost.
- Context compressor image pruning: old multimodal tool results have
their image parts stripped instead of being skipped.
- Image-aware token estimation: each image counts as a flat 1500 tokens
instead of its base64 char length (~1MB would have registered as
~250K tokens before).
- COMPUTER_USE_GUIDANCE system-prompt block — injected when the toolset
is active.
- Session DB persistence strips base64 from multimodal tool messages.
- Trajectory saver normalises multimodal messages to text-only.
- `hermes tools` post-setup installs cua-driver via the upstream script
and prints permission-grant instructions.
- CLI approval callback wired so destructive computer_use actions go
through the same prompt_toolkit approval dialog as terminal commands.
- Hard safety guards at the tool level: blocked type patterns
(curl|bash, sudo rm -rf, fork bomb), blocked key combos (empty trash,
force delete, lock screen, log out).
- Skill `apple/macos-computer-use/SKILL.md` — universal (model-agnostic)
workflow guide.
- Docs: `user-guide/features/computer-use.md` plus reference catalog
entries.
44 new tests in tests/tools/test_computer_use.py covering schema
shape (universal, not Anthropic-native), dispatch routing, safety
guards, multimodal envelope, Anthropic adapter conversion, screenshot
eviction, context compressor pruning, image-aware token estimation,
run_agent helpers, and universality guarantees.
469/469 pass across tests/tools/test_computer_use.py + the affected
agent/ test suites.
- `model_tools.py` provider-gating: the tool is available to every
provider. Providers without multi-part tool message support will see
text-only tool results (graceful degradation via `text_summary`).
- Anthropic server-side `clear_tool_uses_20250919` — deferred;
client-side eviction + compressor pruning cover the same cost ceiling
without a beta header.
- macOS only. cua-driver uses private SkyLight SPIs
(SLEventPostToPid, SLPSPostEventRecordTo,
_AXObserverAddNotificationAndCheckRemote) that can break on any macOS
update. Pin with HERMES_CUA_DRIVER_VERSION.
- Requires Accessibility + Screen Recording permissions — the post-setup
prints the Settings path.
Supersedes PR #4562 (pyautogui/Quartz foreground backend, Anthropic-
native schema). Credit @0xbyt4 for the original #3816 groundwork whose
context/eviction/token design is preserved here in generic form.
* feat(profile): shareable profile distributions (pack/install/update/info)
Closes#20456.
Turns a profile into a portable, versioned artifact. Packs SOUL.md, config,
skills, cron, and an env-var manifest into a tar.gz that others can install
from a local path, URL, or git repo. Updates re-pull the distribution while
preserving user data (memories, sessions, auth.json, .env) and the user's
config.yaml overrides.
New subcommands (under hermes profile, no parallel tree):
hermes profile pack <name> [-o FILE]
hermes profile install <source> [--name N] [--alias] [--force] [-y]
hermes profile update <name> [--force-config] [-y]
hermes profile info <name>
Manifest (distribution.yaml at the profile root): name, version,
hermes_requires, author, env_requires, distribution_owned.
Security:
- Installer shows manifest + env-var requirements before mutating disk;
confirmation required unless -y.
- auth.json and .env are never packed (same exclude set as profile export).
- Cron jobs are packed but NOT auto-scheduled — user is pointed at
'hermes -p <name> cron list' to review.
- Archive extraction rejects path traversal (../ members).
- Alias creation is opt-in via --alias.
Update semantics:
- Distribution-owned paths (SOUL.md, skills/, cron/, mcp.json, manifest):
replaced from the new archive.
- config.yaml: preserved by default; --force-config to overwrite.
- User-owned paths (memories/, sessions/, auth.json, .env, state.db*,
logs/, workspace/, plans/, home/, *_cache/, local/): never touched.
Version pin:
hermes_requires accepts >=, <=, ==, !=, >, < or a bare version (treated
as >=). Install fails with a clear error when the running Hermes version
doesn't satisfy the spec.
Sources supported by 'install':
- Local .tar.gz / .tgz archive
- Local directory
- HTTP(S) URL pointing to a .tar.gz (uses httpx, already a dep)
- Git URL (github.com/user/repo, https://..., git@..., ssh://, git://)
Tests: 43 new unit tests (manifest parsing, version checks, env template,
pack/install/update round-trip, config-preservation, security).
E2E validated via real CLI invocations against an isolated HERMES_HOME
covering pack, install with confirmation, update preservation, update
--force-config, decline-preview, duplicate-install rejection, and
version-requirement rejection.
* refactor(profile-dist): git-only — drop tar.gz/HTTP transports and pack
Scope-cut on top of the original distribution PR: a profile distribution
is now exclusively a git repository (or a local directory during
development). The tar.gz / HTTP archive transports and the matching
`hermes profile pack` subcommand have been removed.
Why:
* GitHub tags, branches, and commits are already the right versioning
primitive. Tag pushes do for us what 'pack + upload' did.
* `hermes profile export` / `import` already cover local backup and
restore; they are not a distribution format and stay untouched.
* One transport means one install/update code path, one doc page,
and one mental model. The extra source types doubled the surface
for no real user win — GitHub auto-attaches release tarballs, and
`git bundle` / `git clone --mirror` cover the airgap case.
Changes:
* hermes_cli/profile_distribution.py — removed pack_profile,
_fetch_tar_archive (_http_fetch), _safe_extract, _archive_roots,
_safe_parts, _find_dist_root, tarfile/io/urlparse imports. The
new _stage_source has two arms: git URL → clone, local directory
→ use in place.
* hermes_cli/main.py — removed the 'pack' subparser and action
handler. Install help text updated to match the reduced source list.
* tests/hermes_cli/test_profile_distribution.py — rewritten around a
local-directory staging fixture. The install/update/describe suites
now build a distribution tree on disk directly and install from it,
which is what a real git clone produces after .git is stripped.
Dropped TestPack, TestFindDistRoot, and the tar-specific security
test. New tests cover _looks_like_git_url, env_example emission,
hermes_requires enforcement, and 'installer does not import
credentials if an author mistakenly leaks them in the staging tree'.
* website/docs/reference/profile-commands.md — 'Distribution commands'
section rewritten around git. Added a 'Publishing a distribution'
section. export/import stay documented as local backup/restore.
* website/docs/reference/cli-commands.md — dropped 'pack' from the
profile subcommand table.
* website/package.json — 'lint:diagrams' now passes
--exclude-code-blocks to ascii-guard. Without it, markdown tables
and box-drawing diagrams inside fenced code blocks were being
misidentified as malformed ASCII boxes, blocking the PR's
docs-site-checks CI with 8 false-positive errors.
Validation:
* Targeted suite: tests/hermes_cli/test_profile_distribution.py —
56/56 pass (down from 43 — reorganized to cover the new
local-dir paths).
* Regression: test_profiles.py + test_profile_export_credentials.py
102/102 still pass. export/import behaviour unchanged.
* Docs lint: ascii-guard lint --exclude-code-blocks docs returns
0 errors (was 8 on the PR before the flag bump).
* E2E: ran the real `hermes profile install`/`info` against a
local staging dir under an isolated HERMES_HOME — install writes
SOUL.md + skills to the target profile, info reads the manifest
back, a bogus source produces a clear error, and `hermes profile
pack` is now rejected by argparse as expected.
* feat(profile-dist): distribution-aware list/show/delete + installed_at + env preview
Polish pass on top of the git-only scope cut. Five additions, all small,
wiring into existing commands rather than adding new surface.
1. `installed_at` timestamp on the manifest
* Stamped automatically inside plan_install() on both fresh install
and update — ISO-8601 UTC, seconds resolution.
* Surfaced in `hermes profile info` as `Installed: <ts>`.
* Lets users tell "installed 6 months ago, needs update" from
"installed yesterday" without guessing from file mtimes.
2. `hermes profile list` grows a `Distribution` column
* Plain profiles: "—"
* Distribution profiles: "<name>@<version>" (e.g. `telemetry@1.2.3`)
* ProfileInfo gains three optional fields — distribution_name,
distribution_version, distribution_source — populated by a new
_read_distribution_meta() helper that swallows manifest read errors
so a broken distribution.yaml in one profile can't break `list`
for the others.
3. `hermes profile show` and `hermes profile delete` surface
distribution provenance
* show: `Distribution: name@version` + `Installed from: <source>`
plus a pointer to `hermes profile info <name>` for the full
manifest.
* delete: same lines in the pre-confirmation preview, so a user
deleting "telemetry" can see it came from
`github.com/kyle/telemetry-distribution` before they type
`telemetry` to confirm. No change to the confirmation gate itself —
deletion semantics are identical to plain profiles.
4. Install preview checks env vars against the current environment
* Replaces the "Env vars you'll need to set:" header with a simpler
"Env vars:" block.
* Each required var is labeled:
- `✓ set` — already in `os.environ` OR present as a key in the
target profile's existing .env (update case).
- `needs setting` — required but not found in either place.
- `—` — optional.
* Mirrors pip's "Requirement already satisfied" UX: no unnecessary
nagging about keys the user already has configured.
5. Docs: private distributions
* New "Private distributions" section in
website/docs/reference/profile-commands.md explaining that we
shell out to the user's `git` binary, so SSH keys / credential
helpers / GitHub CLI stored creds all work transparently. One
paragraph, two examples.
* `hermes profile info` section updated to mention `Installed:`.
Module-level hoist:
* `from datetime import datetime, timezone` was previously lazy-imported
inside plan_install(). Hoisted to module scope so tests can monkeypatch
`hermes_cli.profile_distribution.datetime` to freeze time.
Tests (+7):
* TestInstalledAtStamp.test_install_stamps_installed_at — format check
(4-digit year, 'T', +00:00 suffix).
* TestInstalledAtStamp.test_update_refreshes_installed_at — freezes
datetime.now() to 2099-01-01 and confirms update writes a new stamp.
* TestProfileInfoDistribution.test_installed_distribution_shows_in_list
— ProfileInfo.distribution_{name,version,source} populated after install.
* TestProfileInfoDistribution.test_plain_profile_has_no_distribution_fields
— plain profiles have None.
* TestProfileInfoDistribution.test_malformed_manifest_does_not_break_list
— broken distribution.yaml in one profile doesn't break list_profiles().
Validation:
* 163/163 tests pass (56 distribution + 102 profile regression +
5 new from this commit — up from 158).
* docs-lint: 0 errors.
* E2E verified: install preview shows ✓/needs-setting per env var,
`profile list` shows Distribution column, `profile show` + `delete`
preview mentions source URL, `info` shows Installed: timestamp.
* fix(profile-dist): clean errors + warn when overwriting plain profiles
Two small polish fixes found during collision sweeps of the PR:
1. ValueError from validate_profile_name now caught cleanly
* A distribution.yaml whose 'name' field can't be used as a profile
identifier (spaces, path traversal, etc.) raises ValueError from
hermes_cli.profiles.validate_profile_name, which was escaping as a
raw Python traceback from 'hermes profile install/update/info'.
* Broadened the except clause in all three handlers to catch
(DistributionError, ValueError) — users now see:
Error: Invalid profile name '../../etc/passwd'. Must match
[a-z0-9][a-z0-9_-]{0,63}
instead of a stack trace.
2. Install preview distinguishes plain profile overwrite from
distribution re-install
* When plan.target_dir exists and IS a distribution (has
distribution.yaml), preview still shows the mild
(profile exists — will overwrite distribution-owned files only)
* When plan.target_dir exists but is a HAND-BUILT plain profile (no
distribution.yaml), preview now shows a loud warning:
⚠ Profile exists but is NOT a distribution. Installing here will
overwrite its SOUL.md, skills/, cron/, and mcp.json.
Your memories, sessions, auth.json, and .env will be preserved,
but any hand-edits to distribution-owned files will be lost.
* Users who type 'hermes profile install foo --force' against a
profile they hand-built now see what they're signing up for. User
data is still safe (memories, sessions, auth, .env are in
USER_OWNED_EXCLUDE), but custom SOUL/skills get stomped.
Tests (+2):
* TestErrorSurfaces.test_bad_profile_name_raises_valueerror_not_traceback
* TestErrorSurfaces.test_path_traversal_name_rejected
Validation:
* 165/165 tests pass (was 163).
* E2E: bad manifest names produce 'Error: Invalid profile name ...'
with no traceback; installing over a plain profile shows the warning;
re-installing over an existing distribution shows the normal
overwrite message.
* Bad HTTPS URLs still produce 'Error: git clone failed: ...' — git
itself generates a clean enough message that no wrapper is needed.
* 'install .' works correctly from any cwd.
* fix(profiles): reject reserved names at validate time
Before: `hermes profile create hermes` / `profile install` / `profile rename`
all silently accepted reserved names like `hermes`, `test`, `tmp`, `root`,
`sudo`. The profile directory was created; only alias creation failed (via
check_alias_collision), leaving a confusingly-named profile on disk — e.g.
`~/.hermes/profiles/hermes/` sitting next to `~/.hermes/` itself.
The reserved set already exists (_RESERVED_NAMES, introduced alongside alias
collision detection). This commit moves the check up one layer to
validate_profile_name so every entry point — create, install, import,
rename, dashboard web API — shares the same gate.
The error message points the user at the cause without being cryptic:
Error: Profile name 'hermes' is reserved — it collides with either the
Hermes installation itself or a common system binary. Pick a different
name.
`default` continues to pass through (it's a special alias for ~/.hermes).
_HERMES_SUBCOMMANDS (`chat`, `model`, `gateway`, etc.) stays at
alias-collision time only — those are fine as bare profile names with
`--no-alias`.
Tests (+5): test_reserved_names_rejected parametrized over the full
_RESERVED_NAMES set, matching the existing pattern in TestValidateProfileName.
No existing test uses a reserved name as a profile identifier (greppped
create_profile("hermes|test|tmp|root|sudo") — zero hits).
Validation:
* 170/170 tests pass in the profile suites.
* E2E: `profile create hermes`, `profile install` with manifest
name=hermes, and `profile install ... --name hermes` all produce the
same clean `Error: Profile name 'hermes' is reserved ...` with rc=1
and no traceback. Normal names (`mybot`) still work.
The quick setup flow (recommended for first-time users) silently defaulted
terminal.backend to 'local' without ever presenting the choice. This meant
new users who wanted Docker, SSH, Modal, Daytona, or any other backend had
to know about 'hermes setup terminal' — which most wouldn't discover until
later.
Now the quick setup flow is:
1. Provider selection
2. API key
3. Terminal backend (local/Docker/Modal/SSH/Daytona/Vercel/Singularity)
4. Messaging platform
5. Done
The terminal backend is a foundational decision (where ALL commands run)
and belongs in the onboarding path alongside provider selection.
Weak judge models (e.g. deepseek-v4-flash) return empty strings or prose
when asked for the strict {done, reason} JSON verdict. The old code
failed-open to continue on every such turn, burning the entire turn
budget with log lines like
judge returned empty response
judge reply was not JSON: "Let me analyze whether the goal..."
and /goal clear could not stop it mid-loop without /stop.
After N=3 consecutive *parse* failures (transport/API errors don't
count — those are transient), the loop auto-pauses and prints:
⏸ Goal paused — the judge model (3 turns) isn't returning the
required JSON verdict. Route the judge to a stricter model in
~/.hermes/config.yaml:
auxiliary:
goal_judge:
provider: openrouter
model: google/gemini-3-flash-preview
Then /goal resume to continue.
The counter resets on any usable reply (both "done"/"continue" and
API errors) and persists across GoalManager reloads so cross-session
resumes carry the correct state.
Also fixes test_goal_verdict_send.py sharing a hardcoded session_id
across tests — the shared id only worked because the previous
_post_turn_goal_continuation was a never-awaited coroutine. Now that
PR #19160 made it properly awaited, the xdist test-leakage bug
surfaced. Each test gets a unique session_id via uuid suffix.
* feat(kanban): add `specify` — auxiliary LLM fleshes out triage tasks
The Triage column shipped with a placeholder 'a specifier will flesh
out the spec', but the specifier itself was never built. This wires
it up as a dedicated CLI verb.
`hermes kanban specify <id>` calls the auxiliary LLM (configured under
`auxiliary.triage_specifier`) to expand a rough one-liner into a
concrete spec — tightened title plus a body with Goal / Approach /
Acceptance criteria / Out-of-scope sections — then atomically flips
`status: triage -> todo` and recomputes ready so parent-free tasks
go straight to the dispatcher on the same tick.
Surface:
hermes kanban specify <task_id> # single task
hermes kanban specify --all [--tenant T] # sweep triage column
hermes kanban specify ... --author NAME # audit-comment author
hermes kanban specify ... --json # one JSON line per task
Design choices:
- Parent gating is preserved. specify_triage_task flips to 'todo',
then recompute_ready promotes to 'ready' only when parents are
done — same rule as a normal parent-gated todo.
- No daemon, no background watcher. Every invocation is explicit —
keeps cost predictable and doesn't fight the dispatcher loop.
- Response parse is lenient: strict JSON preferred, markdown-fence
tolerated, raw-body fallback on malformed JSON so the LLM can't
strand a task in triage.
- All failure modes (no aux client, API error, task moved out of
triage mid-call) return SpecifyOutcome(ok=False, reason=...) so
--all continues past individual failures.
Changes:
hermes_cli/kanban_db.py + specify_triage_task()
hermes_cli/kanban_specify.py NEW (~220 LOC — prompt, parse, call)
hermes_cli/kanban.py + specify subcommand + _cmd_specify
hermes_cli/config.py + auxiliary.triage_specifier task slot
website/docs/user-guide/features/kanban.md specify + config notes
website/docs/reference/cli-commands.md CLI reference entry
tests/hermes_cli/test_kanban_specify_db.py NEW (10 tests)
tests/hermes_cli/test_kanban_specify.py NEW (20 tests)
Validation: 30/30 targeted tests pass. E2E: triage task -> specify ->
ends in 'ready' with events [created, specified, promoted] and the
audit comment recorded under the configured author.
* feat(kanban): wire specifier into dashboard and gateway slash
Follow-ups to the initial PR #21435 — closes the two gaps I'd left as
post-merge: dashboard button and first-class gateway surface.
Dashboard (plugins/kanban/dashboard/)
- POST /tasks/:id/specify NEW endpoint. Thin wrapper around
kanban_specify.specify_task(). Returns the CLI outcome shape
({ok, task_id, reason, new_title}); ok=false with a human reason
is a 200, not a 4xx, so the UI can render it inline without
treating 'no aux client configured' as a crash.
- Runs sync in FastAPI's threadpool because the LLM call can take
tens of seconds on reasoning models.
- Pins HERMES_KANBAN_BOARD around the specify call so the module's
argless kb.connect() lands on the right board.
- dist/index.js: doSpecify callback threaded through the drawer →
TaskDetail → StatusActions prop chain. ✨ Specify button appears
ONLY when task.status === 'triage' (elsewhere the backend would
reject anyway — hide the button to keep the action row clean).
Busy state (Specifying…) + inline success/error banner under the
button using the response.reason text.
- dist/style.css: tiny hermes-kanban-msg-ok / -err classes using
existing --color vars so themes reskin cleanly.
Gateway slash (/kanban specify)
- Already works via the existing run_slash → build_parser →
kanban_command pipeline. No code change needed — slash commands
inherit the argparse tree automatically. Added coverage:
test_run_slash_specify_end_to_end (create --triage, specify, verify
promotion + retitle) and test_run_slash_specify_help_is_reachable.
Tests
- tests/plugins/test_kanban_dashboard_plugin.py: 3 new tests for the
REST endpoint — happy path, non-triage rejection as ok=false 200,
missing aux client as ok=false 200.
- tests/hermes_cli/test_kanban_cli.py: 2 new slash-surface tests.
Docs
- website/docs/user-guide/features/kanban.md: dashboard action row
description mentions ✨ Specify + all three surfaces. REST table
gains /tasks/:id/specify. Slash examples include /kanban specify.
Validation: 340/340 targeted tests pass. E2E via TestClient: create a
triage task over REST → POST /specify with mocked aux client → task
moves to 'ready' column on /board with new title and body applied.
Both implement WebSearchProvider via tools/web_providers/ — matching the
existing SearXNG pattern (PR #5c906d702). Search-only; pair with any
extract provider via web.extract_backend.
- tools/web_providers/brave_free.py — Brave Search API (free tier, 2k
queries/mo). Uses BRAVE_SEARCH_API_KEY as X-Subscription-Token.
- tools/web_providers/ddgs.py — DuckDuckGo via the ddgs Python package.
No API key; gated on package importability.
- tools/web_tools.py: both backends added to _get_backend() config list
and auto-detect chain (trails paid providers), _is_backend_available,
web_search_tool dispatch, web_extract_tool + web_crawl_tool search-only
refusals, check_web_api_key, and the __main__ diagnostic. Introduces
_ddgs_package_importable() helper so tests can monkeypatch a single
symbol for the ddgs availability check.
- hermes_cli/tools_config.py: picker entries for both providers; ddgs
gets a post_setup handler that runs `pip install ddgs`.
- hermes_cli/config.py: BRAVE_SEARCH_API_KEY in OPTIONAL_ENV_VARS.
- scripts/release.py: AUTHOR_MAP entry for @Abd0r.
- tests: 14 new tests (brave-free) + 15 new tests (ddgs) covering
provider unit behavior, backend wiring, and search-only refusals.
Salvages the brave-free + ddgs portion of PR #19796. Not included: the
in-line helpers in web_tools.py (replaced with provider modules to match
the shipped architecture), the lynx-based extract path (these backends
should refuse extract with a clear error — users pair with a real
extract provider), and scripts/start-llama-server.sh (unrelated).

cmd_update's auto-restart path could leave the gateway dead after a
transient failure in systemd's own auto-restart window. Reproduced
on Ubuntu 25.10 + systemd 257: after update, gateway drains and exits 75,
systemd's first respawn 60s later fails (status=200/CHDIR with
"No such file or directory" on a WorkingDirectory that demonstrably
exists), the unit ends up in RestartMaxDelaySec=300 backoff, and
cmd_update's fallback 'systemctl restart' never recovers it — leaving
users with a permanently silent gateway until they manually run
'systemctl reset-failed'.
The fix mirrors the recovery pattern 'hermes gateway restart'
(systemd_restart) got in PR #20949: always reset-failed before
restart, on both the initial fallback and the retry. Also rewrites
the final failure message to tell the user to reset-failed +
restart (not just restart, which is the step that already failed
twice).
Adds a per-task override for the consecutive-failure circuit breaker,
so individual tasks can opt out of the global ``kanban.failure_limit``
without dragging everyone else with them.
Resolution order (now three tiers):
1. per-task ``max_retries`` (new, this commit)
2. caller-supplied ``failure_limit`` — the gateway threads
``kanban.failure_limit`` from config here
3. ``DEFAULT_FAILURE_LIMIT`` (2)
Changes:
- ``tasks.max_retries INTEGER`` column + migration for existing DBs
(NULL = no override, matches pre-column behavior).
- ``Task.max_retries`` field + ``from_row`` plumbing.
- ``create_task(..., max_retries=N)`` kwarg.
- ``_record_task_failure`` reads the per-task value first and records
``limit_source`` + ``effective_limit`` on the ``gave_up`` event so
operators can see which tier won.
- CLI: ``hermes kanban create --max-retries N`` (rejects ``< 1``).
- CLI: ``hermes kanban show`` surfaces the effective threshold +
source (``(task)``, ``(config kanban.failure_limit)``, ``(default)``).
- CLI: ``_task_to_dict`` includes ``max_retries`` in ``--json`` output.
Key design choice vs. the earlier #20972 attempt:
- No new config key. The existing ``kanban.failure_limit`` (landed in
#21183) is the dispatcher-tier source — no silent break for users
who already tuned it.
- No ``!=`` sentinel for "is config set" (which would misfire when
config equals the default). The tier-winner is determined purely
by "is per-task override set" — the dispatcher always wins when
per-task is NULL, regardless of whether the caller passed the
default or a configured value.
E2E verified across four scenarios: default-only (trips at 2),
config-only (trips at caller's value), per-task-only beats default
(trips at task value), per-task beats larger config (trips at task
value). ``gave_up`` event metadata correctly records ``limit_source``
and ``effective_limit`` in all cases.
Tests:
- ``test_per_task_max_retries_overrides_dispatcher_limit`` — task=1
beats caller=10.
- ``test_per_task_max_retries_allows_more_than_default`` — task=5
does not trip at caller=default of 2.
- ``test_max_retries_none_falls_through_to_dispatcher_limit`` — None
honors caller's config value (4), records ``limit_source=dispatcher``.
Full kanban trio (db + core + cli + tools + dashboard-plugin): 342

Supersedes: #20972 (@jelrod27) — credit in PR close comment.
Ref: #20263 (tangentially — the reporter asked about adapter API
drift, not retry caps, but the CLI discussion there is what
surfaced the original ask).
PairingStore.approve_code() didn't consult _is_locked_out(), so after
MAX_FAILED_ATTEMPTS bad approvals the lockout flag was set but a valid
code still got accepted — any pending code (legitimately issued or
attacker-obtained) could be approved during the 1-hour lockout window,
nullifying the brute-force protection.
- gateway/pairing.py: lockout check runs in approve_code() right after
_cleanup_expired, before the pending lookup. Returns None on lockout.
- tests/gateway/test_pairing.py: test_lockout_blocks_code_approval pins
the regression — reporter's exact reproducer (generate valid code,
exhaust attempts with WRONGCODE, try to approve valid code) must
return None and leave is_approved == False. Also pins recovery: once
lockout expires, the still-pending code approves normally.
- hermes_cli/pairing.py: _cmd_approve distinguishes the two None cases.
On lockout, prints 'Platform locked out... clears in N minutes. To
reset sooner, delete the _lockout:<platform> entry from
_rate_limits.json' instead of the misleading 'Code not found or
expired' message. 29/29 pairing tests pass; E2E-verified with
reporter's exact Python reproducer.
Widen the platform-plugin surface so plugins can self-configure from env
vars and opt into cron home-channel delivery without editing core files.
Closes the scope gap that forced every new platform (Google Chat, Teams,
IRC, future) to either touch gateway/config.py, cron/scheduler.py, and
hermes_cli/config.py or live without env-only setup.
Changes:
- gateway/platform_registry.py: two new optional PlatformEntry fields.
- env_enablement_fn: () -> Optional[dict]. Called during
_apply_env_overrides BEFORE the adapter is constructed. Returned
dict fields are merged into PlatformConfig.extra; the special
'home_channel' key (if present) becomes a proper HomeChannel
dataclass on the PlatformConfig.
- cron_deliver_env_var: name of the *_HOME_CHANNEL env var. When set,
the plugin platform is a valid cron deliver= target and cron reads
the env var to resolve the default chat/room ID.
- gateway/config.py: the existing plugin-platform enable pass at the
bottom of _apply_env_overrides now calls env_enablement_fn and seeds
extras/home_channel. No effect on plugins that don't set the new
field.
- cron/scheduler.py: _is_known_delivery_platform and
_resolve_home_env_var fall through to the registry when the platform
isn't in the hardcoded built-in sets. New _iter_home_target_platforms
helper iterates built-ins + plugin platforms for the deliver=origin
fallback.
- gateway/run.py: _home_target_env_var now consults the new resolver so
plugin-defined home channels work for non-cron call sites too.
- hermes_cli/config.py: new _inject_platform_plugin_env_vars() sibling
of _inject_profile_env_vars(). Scans plugins/platforms/*/plugin.yaml
at import time and contributes entries to OPTIONAL_ENV_VARS so
'hermes config' UI discovers them. Supports bare-string and rich-dict
requires_env entries plus a new optional_env list for non-required
vars (home channels, allowlists).
All additions are strictly opt-in. Existing plugins (IRC, Teams,
image_gen, memory) see zero behavior change until they adopt the new
fields.
Mirrors the Slack `allowed_channels` feature (PR #7401) and Discord's
`allowed_channels` (PR #7044) across the remaining group-capable platforms.
All five platforms (Slack + Discord + the four added here) now follow the
same pattern: primary config via config.yaml, env-var fallback as an escape
hatch — matching the project policy that .env is for secrets only and
behavioral settings belong in config.yaml.
Also fixes a duplicate `slack` key in DEFAULT_CONFIG introduced by PR
#7401 (the later entry silently overwrote `allowed_channels`, `require_mention`,
and `free_response_channels` at dict-literal evaluation time).
Platforms added:
- Telegram: `telegram.allowed_chats` (env alias: `TELEGRAM_ALLOWED_CHATS`)
- Mattermost: `mattermost.allowed_channels` (env alias: `MATTERMOST_ALLOWED_CHANNELS`)
- Matrix: `matrix.allowed_rooms` (env alias: `MATRIX_ALLOWED_ROOMS`)
- DingTalk: `dingtalk.allowed_chats` (env alias: `DINGTALK_ALLOWED_CHATS`)
Mattermost and Matrix previously had NO config.yaml bridging for any of
their gating settings; this PR adds `load_gateway_config` bridges for them
(Mattermost gets require_mention + free_response_channels + allowed_channels;
Matrix gets allowed_rooms on top of its existing bridges for require_mention
and free_response_rooms).
Semantics identical everywhere:
- Empty = no restriction (fully backward compatible).
- Non-empty = hard whitelist: non-listed chats are silently ignored,
even when the bot is @mentioned.
- DMs bypass the check entirely.
DEFAULT_CONFIG merges the duplicate `slack` block and adds new `mattermost`
and `matrix` blocks so all gating settings surface in defaults.
Not included: Feishu (has its own per-chat `chat_rules` system that covers
this use case differently), WhatsApp (already has `group_allow_from` via
`group_policy: allowlist`), pure-DM platforms (Signal, SMS, BlueBubbles,
Yuanbao — no group concept).
The Hermes dashboard previously assumed it was served at the root of its
host (e.g. https://kanban.tilos.com/). When mounted behind a path-prefix
reverse proxy (e.g. https://mission-control.tilos.com/hermes/), the SPA
404'd because:
- index.html shipped absolute /assets/index-*.js URLs
- React Router had no basename
- The plugin loader hit /dashboard-plugins/<name>/... at the root host
- CSS in the bundle had absolute url(/fonts/...) references
This patch makes the dashboard prefix-aware at runtime, no rebuild
required. The proxy injects 'X-Forwarded-Prefix: /hermes' on every
request and the Python server:
- Rewrites href/src in served index.html to '${prefix}/assets/...'
- Injects 'window.__HERMES_BASE_PATH__="${prefix}"' for the SPA to read
- Rewrites url() refs in CSS at serve time
The SPA reads window.__HERMES_BASE_PATH__ once at boot and:
- Prefixes all /api/... fetches via api.ts
- Prefixes all /dashboard-plugins/... script/css URLs in usePlugins
- Sets <BrowserRouter basename={...}> so client-side routing works
When no X-Forwarded-Prefix header is present, behavior is unchanged
(empty prefix => serves at root, kanban.tilos.com keeps working).

Add tencent/hy3-preview (without :free suffix) as a paid model route
alongside the existing free variant. This allows seamless transition
when the model moves from free to paid on OpenRouter — both routes
coexist so neither side's timing causes breakage.
Changes:
- models.py: add ("tencent/hy3-preview", "") to OPENROUTER_MODELS
- model-catalog.json: add paid variant entry
- tests: add assertions for paid route presence
The :free entry can be removed in a follow-up PR once OpenRouter
confirms the free route is deprecated.

The alibaba-coding-plan provider (DashScope coding-intl endpoint) was
defined in providers.py but missing from _PROVIDER_MODELS in models.py.
This caused /model to show "0 models" for this provider even though
credentials were configured and the provider was functional.
Add the curated model list so the provider picker displays available
models correctly.
- Add hermes dashboard examples to the CLI help epilogue so users can
discover the web UI command from 'hermes --help' output
- Add an independent 'Test dashboard subcommand' CI step that verifies
'hermes dashboard --help' works in the Docker image, with its own
mkdir/chown setup to remain independent of the prior smoke test step
- Prevents regressions like #9153 where the dashboard subcommand was
present in source but missing from the published Docker image
Closes#9153
Per repo policy, ~/.hermes/.env is for secrets only. Guild IDs are
behavioral configuration, not secrets. Replacing the
DISCORD_DM_ROLE_AUTH_GUILD env var from the original fix with
discord.dm_role_auth_guild in config.yaml.
- New module-level _read_dm_role_auth_guild() helper reads
hermes_cli.config.read_raw_config()['discord']['dm_role_auth_guild'].
Fails closed on any parse error (safe default = DM role-auth off).
- DEFAULT_CONFIG['discord'] gains dm_role_auth_guild: '' with a comment
documenting the opt-in.
- Tests patch hermes_cli.config.read_raw_config directly (via the
_set_dm_role_auth_guild helper) instead of setenv/delenv. 12 tests
in test_discord_roles_dm_scope pass; no env var involvement.
- Docstring + module docstring + comments updated to reference
discord.dm_role_auth_guild.
- E2E verified with real imports across 6 scenarios: unset, int,
string, garbage, zero, and (crucially) env-var-only-no-config all
return None except the valid int/string cases. Env var has zero
effect — policy compliance confirmed.
Lists the skills sitting in ~/.hermes/skills/.archive/ so users have
something to pass to `hermes curator restore`. `curator status` already
shows counts; this fills the name-discovery gap.
Archive layout is flat (`archive_skill` writes to `.archive/<skill>/`),
so the directory name IS the skill name — no frontmatter parsing
needed. Timestamped collision directories (`<skill>-<ts>`) are listed
literally; user can still pass them to `restore`.
Reshape of @EvilDrag0n's #20651, simplified: drop the frontmatter
rglob + preamble/trailer output + duplicate subcommand registration.

Enables plugins to transform LLM output text after generation,
useful for vocabulary/personality transformation without burning
inference tokens.
Follows same pattern as transform_tool_result and transform_terminal_output:
- First non-empty string result wins
- Fail-open: exceptions logged as warnings, agent continues
- Signature: (response_text, session_id, model, platform)
