- dep_ensure.py: use get_hermes_home() instead of hand-rolled env var
- dep_ensure.py: add "chrome" to browser name list (was inconsistent with browser_tool.py)
- main.py _cmd_update_check: use detect_install_method() directly instead of redundant .git check
- main.py _cmd_update_pip: build command list directly instead of fragile split() on display string
- banner.py: rename _check_via_pypi → check_via_pypi (cross-module public API)
One-shot bootstrap that installs non-Python deps (node, browser,
ripgrep, ffmpeg) via ensure_dependency(), then runs setup if no
provider is configured. Closes the gap between `pip install` and
the full user-facing experience.
Also fixes 3 pre-existing test regressions caused by earlier commits:
- test_recommended_update_command: mock detect_install_method for git env
- test_check_for_updates_no_git_dir: now falls back to PyPI, not None
- test_plist_path_includes_node_modules_bin: skip when dir absent
Before: missing node → hard exit; missing browser → FileNotFoundError.
After: both try ensure_dependency() first, which prompts interactively
and delegates installation to install.sh --ensure.
ripgrep and ffmpeg already degrade gracefully (grep fallback, skip
conversion) so they don't need wiring.
Also documents the design rationale in dep_ensure.py: detection and
prompting live in Python (portable, instant, UX-integrated); only
the actual installation delegates to install.sh (1900 lines of
battle-tested OS/package-manager logic).
_cmd_update_check() had its own `.git` gate separate from _cmd_update_impl.
For pip installs, fork to _check_via_pypi() and display the result with
the correct recommended_update_command().
- banner.py: remove redundant `import json as _json` (json already at module level)
- main.py: _cmd_update_pip now delegates to recommended_update_command_for_method
instead of duplicating the uv-vs-pip detection logic
- main.py: remove redundant `import subprocess as _sp` (subprocess already at module level)
Match the full set of subdirs created by install.sh: pairing, hooks,
image_cache, audio_cache, and skills are now pre-created alongside the
existing cron, sessions, logs, logs/curator, and memories dirs. This
makes hermes doctor checks cleaner without changing any runtime behaviour.
When .git is absent and detect_install_method returns "pip", fork
hermes update to run `uv pip install --upgrade hermes-agent` (or
`python -m pip install --upgrade hermes-agent` as fallback) instead of
hard-exiting with "Not a git repository".
Adds detect_install_method() to identify nixos/homebrew/git/pip installs,
and recommended_update_command_for_method() to return the right upgrade command
for each method. Updates recommended_update_command() to use these for pip-installed
instances (no .git dir, not managed).
Add _find_bundled_tui() that checks for hermes_cli/tui_dist/entry.js
(present in wheel installs) and wire it into _make_tui_argv() between
the HERMES_TUI_DIR prebuilt path and the npm install fallback.
Extract PATH building into _build_service_path_dirs() that skips directories
which don't exist on disk (e.g. node_modules/.bin for pip installs) and also
includes ~/.hermes/node/bin and ~/.hermes/node_modules/.bin for agent-browser.
When cli-config.yaml.example is not present (e.g. pip wheel install),
fall back to writing DEFAULT_CONFIG via save_config() instead of
warning and requiring a manual fix.
For pip-installed hermes-agent (no .git directory), fall back to
querying PyPI's JSON API to compare __version__ against the latest
published release, using stdlib only (urllib + json, no packaging dep).
Stop the gateway from exiting (or systemd-restart-looping) when a single
messaging adapter fails at startup or runtime. A misconfigured WhatsApp
(npm install timeout, unpaired bridge, missing creds.json) used to take
the entire gateway down, killing cron jobs and any other connected
platforms with it.
Changes:
• Startup (gateway/run.py): when connected_count==0 but the only
errors are retryable, log a degraded-state warning and keep the
gateway alive instead of returning False. Reconnect watcher then
recovers platforms as their underlying problem clears.
• Runtime (gateway/run.py _handle_adapter_fatal_error): when the last
adapter goes down with a retryable error and is queued for
reconnection, stay alive instead of exit-with-failure. Previously
this triggered systemd Restart=on-failure, which created infinite
restart loops on persistent retryable failures (proxy outage,
repeated bridge crashes).
• Reconnect watcher (gateway/run.py _platform_reconnect_watcher):
replace the 20-attempt hard drop with a circuit-breaker pause.
After _PAUSE_AFTER_FAILURES (10) consecutive retryable failures, the
platform stays in _failed_platforms with paused=True so the watcher
skips it but the operator can still see and resume it. Non-retryable
errors still drop out of the queue immediately. Resolves#17063
(gateway giving up on Telegram after 20 attempts).
• WhatsApp preflight (gateway/platforms/whatsapp.py): refuse to start
the Node bridge when creds.json is missing. Sets a non-retryable
whatsapp_not_paired fatal error so the watcher drops it cleanly
with a single 'run hermes whatsapp' log line instead of paying the
30s bridge bootstrap timeout on every gateway start.
• WhatsApp setup ordering (hermes_cli/main.py cmd_whatsapp): only set
WHATSAPP_ENABLED=true once pairing actually succeeds. Previously
the wizard wrote the env var at step 2 (before npm install and QR
pairing), so any Ctrl+C left .env claiming WhatsApp was ready when
the bridge had no creds.json. Also propagate the env var when the
user keeps an existing pairing on a re-run.
• /platform slash command (hermes_cli/commands.py + gateway/run.py):
new gateway-only command for manual circuit-breaker control.
/platform list — show connected + failed/paused platforms
/platform pause <name> — silence a known-broken platform
/platform resume <name> — re-queue a paused platform
Tests:
• New: pause/resume helpers, /platform list|pause|resume command,
WhatsApp creds.json preflight, WhatsApp setup ordering.
• Updated: stale assertions that codified the old 'exit and let
systemd restart' behavior in test_runner_fatal_adapter.py,
test_runner_startup_failures.py, and test_platform_reconnect.py
(the 20-attempt give-up test became a circuit-breaker pause test).
5488 tests pass in tests/gateway/.
Two loopback-redirect OAuth flows (xAI Grok, Spotify) silently fail when
Hermes runs on a remote host: the auth server redirects to
127.0.0.1:<port> on the user's laptop, not on the remote box. The
--no-browser flag only suppresses webbrowser.open() — it doesn't change
the bind address. Symptom xAI surfaces is 'Could not establish
connection. We couldn't reach your app.', followed by a 'xAI
authorization timed out waiting for the local callback' on the CLI side.
Changes
- hermes_cli/auth.py: new _print_loopback_ssh_hint() helper, called from
_xai_oauth_loopback_login() and _spotify_login() right after they
print the redirect URI. Silent off SSH; on SSH prints the exact
'ssh -N -L <port>:127.0.0.1:<port>' command using the actually-bound
port (not the hardcoded constant — the listener auto-bumps when the
preferred port is busy), a provider-specific docs URL, and a link to
the new shared guide.
- website/docs/guides/oauth-over-ssh.md (new): single source of truth
for the tunnel pattern — TL;DR command, jump-box / ProxyJump variant,
mosh+tmux+ControlMaster gotchas, troubleshooting.
- website/docs/guides/xai-grok-oauth.md: fix the two sections that
claimed --no-browser alone was enough; link to the shared guide.
- website/docs/user-guide/features/spotify.md: expand the existing
one-liner; link to the shared guide.
- website/sidebars.ts: register the new page.
- tests/hermes_cli/test_auth_loopback_ssh_hint.py: 7 unit tests
covering SSH-vs-not, loopback-vs-not, malformed URIs, port echo,
with and without provider docs URL.
Drop accounts.mouseion.dev and localhost:20000 / 127.0.0.1:20000 from
the loopback callback CORS allowlist — leftover dev origins. The
redirect_uri is bound to 127.0.0.1 and gated by PKCE + state, so only
xAI's own auth origins are needed.
Co-Authored-By: Jaaneek <Jaaneek@users.noreply.github.com>
Per @mark-xai's review on PR #26457 and the xAI model retirement on
2026-05-15: grok-code-fast-1 is being retired today and aliases redirect
to grok-4.3 (already pinned to the top of the xAI model list by this
PR). Update the two xAI Responses-API test fixtures Mark flagged plus
the picker fallback default in hermes_cli/main.py that uses the same
literal.
Two bugs in the `hermes tools` reconfigure flow caused picking xAI Grok
Imagine for video_gen (or image_gen) to feel like a no-op:
1. `_is_provider_active()` had a branch for `image_gen_plugin_name` but
none for `video_gen_plugin_name`, so a row marked as the active xAI
video provider was never recognized as active. The picker fell through
to the env-var fallback in `_detect_active_provider_index()`, which
matched the FAL row (because `FAL_KEY` is set), so the picker visually
defaulted to FAL even though the user had selected xAI.
2. `_plugin_video_gen_providers()` and `_plugin_image_gen_providers()`
built picker rows from the plugin's `get_setup_schema()` but only
copied `name`, `badge`, `tag`, `env_vars`. The xAI plugins declare
`post_setup: "xai_grok"` so the picker should run the OAuth /
API-key prompt hook after selection — that key was silently dropped,
so the hook never fired from the picker rows.
Adds the missing `video_gen_plugin_name` branch (placed before the
`managed_nous_feature` block, mirroring the existing image_gen branch)
and propagates `post_setup` from the plugin schema into both picker-row
builders. Adds focused tests in `test_video_gen_picker.py` and
`test_image_gen_picker.py`.
Adds a new authentication provider that lets SuperGrok subscribers sign
in to Hermes with their xAI account via the standard OAuth 2.0 PKCE
loopback flow, instead of pasting a raw API key from console.x.ai.
Highlights
----------
* OAuth 2.0 PKCE loopback login against accounts.x.ai with discovery,
state/nonce, and a strict CORS-origin allowlist on the callback.
* Authorize URL carries `plan=generic` (required for non-allowlisted
loopback clients) and `referrer=hermes-agent` for best-effort
attribution in xAI's OAuth server logs.
* Token storage in `auth.json` with file-locked atomic writes; JWT
`exp`-based expiry detection with skew; refresh-token rotation
synced both ways between the singleton store and the credential
pool so multi-process / multi-profile setups don't tear each other's
refresh tokens.
* Reactive 401 retry: on a 401 from the xAI Responses API, the agent
refreshes the token, swaps it back into `self.api_key`, and retries
the call once. Guarded against silent account swaps when the active
key was sourced from a different (manual) pool entry.
* Auxiliary tasks (curator, vision, embeddings, etc.) route through a
dedicated xAI Responses-mode auxiliary client instead of falling back
to OpenRouter billing.
* Direct HTTP tools (`tools/xai_http.py`, transcription, TTS, image-gen
plugin) resolve credentials through a unified runtime → singleton →
env-var fallback chain so xai-oauth users get them for free.
* `hermes auth add xai-oauth` and `hermes auth remove xai-oauth N` are
wired through the standard auth-commands surface; remove cleans up
the singleton loopback_pkce entry so it doesn't silently reinstate.
* `hermes model` provider picker shows
"xAI Grok OAuth (SuperGrok Subscription)" and the model-flow falls
back to pool credentials when the singleton is missing.
Hardening
---------
* Discovery and refresh responses validate the returned
`token_endpoint` host against the same `*.x.ai` allowlist as the
authorization endpoint, blocking MITM persistence of a hostile
endpoint.
* Discovery / refresh / token-exchange `response.json()` calls are
wrapped to raise typed `AuthError` on malformed bodies (captive
portals, proxy error pages) instead of leaking JSONDecodeError
tracebacks.
* `prompt_cache_key` is routed through `extra_body` on the codex
transport (sending it as a top-level kwarg trips xAI's SDK with a
TypeError).
* Credential-pool sync-back preserves `active_provider` so refreshing
an OAuth entry doesn't silently flip the active provider out from
under the running agent.
Testing
-------
* New `tests/hermes_cli/test_auth_xai_oauth_provider.py` (~63 tests)
covers JWT expiry, OAuth URL params (plan + referrer), CORS origins,
redirect URI validation, singleton↔pool sync, concurrency races,
refresh error paths, runtime resolution, and malformed-JSON guards.
* Extended `test_credential_pool.py`, `test_codex_transport.py`, and
`test_run_agent_codex_responses.py` cover the pool sync-back,
`extra_body` routing, and 401 reactive refresh paths.
* 165 tests passing on this branch via `scripts/run_tests.sh`.
Builds on @steezkelly's Bug A fix (#25857, top-level default_permissions
via _insert_managed_block_at_top_level) by addressing the other two
config-corruption bugs described in #26250:
Bug B (duplicate [plugins.X] tables)
- Codex itself writes [plugins."<name>@<marketplace>"] tables to
config.toml when the user runs `codex plugins enable` directly,
before hermes-agent's managed block exists. On the next migrate run,
_query_codex_plugins() re-discovers the same plugins via plugin/list
and render_codex_toml_section() re-emits them inside the managed
block. Codex's strict TOML parser then rejects the duplicate table
header on startup.
- Add _strip_unmanaged_plugin_tables() that drops [plugins.*] tables
from the user-content portion of the file. Only run it when
plugin/list succeeded — if the RPC failed we can't re-emit and
must preserve the user's tables. plugin/list is the source of
truth when it answers.
Bug C (HERMES_HOME pytest-tempdir leak into ~/.codex/config.toml)
- _build_hermes_tools_mcp_entry() read HERMES_HOME directly from
os.environ, so a sibling pytest's monkeypatch.setenv("HERMES_HOME",
tmp_path) silently burned a transient pytest tempdir into the
user's real ~/.codex/config.toml. After pytest reaped the tempdir,
every codex-routed hermes-tools tool call failed silently.
- Derive HERMES_HOME from get_hermes_home() (the canonical resolver
that goes through the profile-aware path) and refuse to emit
obvious test-tempdir paths via _looks_like_test_tempdir() as
belt-and-suspenders for any other callsite that forgets to patch
migrate().
- test_enable_succeeds_when_codex_present in test_codex_runtime_switch.py
invoked the real migrate() (no mock), writing to Path.home() / .codex
using whatever HERMES_HOME the running pytest session had set. Add
the same migrate patch the other apply() tests already use, so the
suite stops touching the user's real ~/.codex/config.toml.
E2E verification (replicating the issue's repro):
- Pre-state config.toml with user [mcp_servers.omx_team_run] +
codex-installed [plugins."tasks@openai-curated"],
HERMES_HOME="/private/var/folders/.../pytest-of-.../..."
- On origin/main: tomllib refuses to load the result with
"Cannot declare ('plugins', 'tasks@openai-curated') twice" AND
the pytest-tempdir HERMES_HOME is burned in.
- On this branch: file parses cleanly, default_permissions is
top-level, exactly one [plugins."tasks@openai-curated"] table
inside the managed block, no HERMES_HOME in the MCP env.
7 new regression tests covering all three bugs + the test-leak guard.
`bash scripts/run_tests.sh tests/hermes_cli/test_codex_runtime_*.py` —
95 passed, 0 failed.
Closes#26250
Replaces bare `except Exception: pass` with debug-level logging
so failures in local endpoint model discovery are diagnosable
instead of silently hidden.
Remove redundant inner `import re` and regex recompilation on every call in
_interpolate_env_vars. Add module-level _ENV_VAR_PATTERN compiled once.
Replace the separate _interpolate_value() in mcp_config.py (which used \w+
and would silently fail on env vars containing hyphens or dots) with the
shared _ENV_VAR_PATTERN from mcp_tool.py. Remove now-unused import re.
Some catalog endpoints (OpenCode Zen, etc.) sit behind a WAF that
returns 403 for the default Python-urllib/<ver> User-Agent. The
generic profile-based live fetch in providers/base.py was silently
failing for any such provider — falling through to the static catalog
and missing newly-launched models.
Set a generic 'hermes-cli/<version>' UA on the catalog probe so every
api_key provider profile benefits. Verified live against opencode-zen:
before this change, profile.fetch_models() raised HTTP 403; after, it
returns 42 models including gpt-5.5, gpt-5.5-pro, kimi-k2.6, glm-5.1
and the *-free variants the static catalog doesn't list.
Also strip the now-stale comment in validate_requested_model() claiming
opencode-zen's /models returns 404 against the HTML marketing site —
the API endpoint at /zen/v1/models returns 200 with valid JSON.
Surfaced by #2651 (@aashizpoudel) — fixes the same user-facing gap
their PR targeted, applied at the right layer so all api_key provider
profiles get live catalogs through the same code path.

The Zed ACP Registry path (uvx --from 'hermes-agent[acp]==X' hermes-acp)
gets a Python-only install. Browser tools depend on the agent-browser npm
package + Chromium, neither of which are in the wheel. Without an
explicit bootstrap, registry users have no path to working browser tools.
Ship a bundled, idempotent bootstrap script (Linux/macOS bash + Windows
PowerShell) inside acp_adapter/bootstrap/ as wheel package-data. New
entry points:
hermes acp --setup-browser # interactive; prompts before Chromium download
hermes acp --setup-browser --yes # non-interactive
hermes-acp --setup-browser
The terminal-auth flow (hermes acp --setup) also offers the browser
bootstrap as a follow-up after model selection, so first-run registry
users get the option without knowing the flag exists.
Key design choices:
- npm install -g --prefix $NODE_PREFIX so we never need sudo. System Node
on PATH is respected; only the install target is redirected to the
user-writable Hermes-managed Node prefix.
- tools/browser_tool.py::_browser_candidate_path_dirs() already walks
$HERMES_HOME/node/bin, so installed binaries are discovered with no
agent-side code change.
- System Chrome/Chromium detection short-circuits the ~400 MB Playwright
download when a suitable browser already exists.
- Bash + PowerShell live as ONE copy each under acp_adapter/bootstrap/.
Not duplicated under scripts/. install.sh and install.ps1 keep their
inline browser blocks for the source-checkout path.
E2E validated end-to-end:
bash bootstrap_browser_tools.sh --skip-chromium
→ installs agent-browser into ~/.hermes/node/bin/
tools.browser_tool._find_agent_browser()
→ returns the installed path
check_browser_requirements()
→ returns True (browser tools register)
Tests:
- tests/acp/test_entry.py: 11 tests covering --setup-browser dispatch
(linux + windows + --yes forwarding + failure propagation), the
terminal-auth follow-up prompt path, and a package-data wheel-shipping
assertion that catches any future pyproject.toml regression.
Docs: website/docs/user-guide/features/acp.md gains a 'Browser tools
(optional)' subsection with the two-line install + what-it-does.
Cron mutation operations (run/pause/resume/remove) and 'hermes cron edit'
now accept a job name in addition to the hex ID, with case-insensitive
matching. Before this, 'hermes cron run my_job_name' died with
'Job with ID my_job_name not found' and forced the user to look up the
hex ID first.
The original PR matched by name but silently picked the first match when
two jobs shared a name. This version refuses to act on an ambiguous name
and surfaces every matching job (id, name, schedule, next_run_at) so the
caller can pick a specific ID.
- cron/jobs.py:
- get_job() stays ID-only (preserves existing call-site semantics for
web_server/api_server/curator/scheduler/test code that always passes
real IDs).
- resolve_job_ref() is the new name-or-ID resolver, used by pause/
resume/trigger/remove_job. Exact ID match wins over a name match
even if a different job's name happens to equal that ID. Ambiguous
name match raises AmbiguousJobReference with all candidate IDs.
- tools/cronjob_tools.py: dispatch site uses resolve_job_ref, surfaces
ambiguous matches as a structured error with the matching IDs.
- hermes_cli/cron.py: 'cron edit' uses resolve_job_ref so editing by
name works and ambiguous names are reported with IDs.
- tests/cron/test_jobs.py: new TestResolveJobRef covering ID match,
case-insensitive name match, ID-wins-over-name, ambiguous refusal,
and that pause/resume/trigger/remove all refuse on ambiguity.
Closes#2627
The freeform /goal judge was capped at max_tokens=200, which reliably
truncated the JSON verdict on reasoning-heavy models (deepseek-v4-pro,
qwq, etc.) — the model burns tokens on hidden reasoning before emitting
visible content, and the first /goal turn's prompt is larger than later
turns, blowing past 200. Symptom: agent.log shows
`judge reply was not JSON: '{"done": true, "reason": "The agent successfully'`
followed by repeated `judge returned empty response` lines, then the
goal pauses with a misleading 'judge model isn't returning the required
JSON verdict' message.
Diagnosed live by @helix4u — empirically verified that raising the
budget on an unmodified worktree makes the failures go away on the
exact configs users were hitting on Nous Plus subscription paths.
Changes:
- DEFAULT_JUDGE_MAX_TOKENS = 4096 (up from 200)
- New auxiliary.goal_judge.max_tokens config knob for tuning in
specifically constrained setups
- _goal_judge_max_tokens() resolves the value with fail-open semantics
(non-int / non-positive / load failure → default). load_config() is
mtime-cached so per-turn lookup is cheap.
Scoped narrowly to the verified root cause — does not introduce a
submit_verdict tool-call schema (see #26162 / #23671 for that direction;
they can land separately if we want them).
Tests: tests/hermes_cli/test_goals.py + tests/cli/test_cli_goal_interrupt.py
+ tests/gateway/test_goal_verdict_send.py — 62/62 passing.
E2E verified: config override honored (8192), missing/garbage/zero
values fall back to 4096, no-auxiliary-section falls back to 4096.

Supersedes #26162, #23671, #23881
Two long-standing prompt_toolkit bugs in the base hermes CLI:
1. Resize duplication. Column-shrink resize used to push 40+ rows of
duplicate chrome (status bar, input rules) into terminal scrollback
every resize. Same wall as pt issues #29 (open since 2014), #1675,
#1933 — aider/xonsh/ipython all use alt-screen to dodge it.
Root cause (verified by reading prompt_toolkit/renderer.py):
_output_screen_diff (renderer.py L232-242) deliberately moves the
cursor to the bottom of the canvas after every paint 'to make sure
the terminal scrolls up'. In non-fullscreen mode this scrolls chrome
content into terminal scrollback on every render — not just on
resize.
Fix: monkey-patch prompt_toolkit.renderer._output_screen_diff to
bypass the reserve-vertical-space cursor move. When pt's logic checks
'if current_height > previous_screen.height', we inflate the previous
screen height so the branch falls through. ~30-line wrapper, no fork
of pt, no alt-screen, no DECSTBM scroll region.
Verified empirically in real Terminal.app: 10 resizes (mixed
shrinks/widens 1300→500→1400) during streaming produced ZERO
scrollback delta, full agent response preserved, status bar pinned
at bottom, no visible duplicates. pt is pinned to ==3.0.52 so the
private-function patch is safe; future pt bumps will need to
re-verify the signature matches.
2. Light-mode terminal visibility. Hardcoded skin colors (#FFF8DC
cornsilk, #FFD700 gold, #B8860B dark goldenrod) are tuned for dark
Terminal.app — invisible on light/cream backgrounds.
Port ui-tui/src/theme.ts detectLightMode() to Python so the base CLI
adapts. Detection priority: HERMES_LIGHT/HERMES_TUI_LIGHT env →
HERMES_TUI_THEME=light|dark → HERMES_TUI_BACKGROUND=#RRGGBB →
COLORFGBG env (xterm/Konsole/urxvt) → OSC 11 query
(\x1b]11;?\x1b\\) with 100ms timeout → default dark. OSC 11 is
tty-gated so gateway/cron/batch/subagent code paths don't pay the
timeout cost.
When light mode is detected, dark-mode colors auto-remap to readable
equivalents (#FFF8DC → #1A1A1A, #FFD700 → #9A6B00, etc). Hooked at
three points:
- _hex_to_ansi() — auto-remaps any color emitted via the ANSI helper
- _build_tui_style_dict() — rewrites pt style strings (chrome bg/fg)
- SkinConfig.get_color() — wrapped at module load so Rich Panel
borders/body text get the remap too
Status-bar foreground colors (#C0C0C0, #888888, etc.) are explicitly
skipped because they're paired with a dark navy bg — remapping them
would make them invisible in dark mode.
3. Other visibility fixes: [thinking] reasoning preview now uses ANSI
dim+italic (\x1b[2;3m) instead of #B8860B so it inherits terminal
default fg color. Input/prompt area defaults to terminal default fg
(was #FFF8DC cornsilk → invisible on cream).

The call site at line 246 is already wrapped in try/except NotImplementedError
(added in #25969). The checker just doesn't peek at surrounding context.
Mark with the suppression comment so the blocking check passes.
Codex review pointed out that even with the sync-assets fix applied,
_build_web_ui still crashes on a stock Windows console before reaching
npm: Python stdout defaults to cp1252 (or similar) and raises
UnicodeEncodeError when print() hits the arrow/check glyphs used for
status messages (→, ✗, ⚠, ✓). Reproduced locally in PowerShell:
$ PYTHONIOENCODING=cp1252 python -c "from hermes_cli.main import _build_web_ui; _build_web_ui(Path('web'), fatal=True)"
UnicodeEncodeError: 'charmap' codec can't encode character '\u2192' ...
The previous PR body claimed "end-to-end verified on Windows 11", but
that was under the venv's default (utf-8) stdout. A plain `py` or
PowerShell invocation would still fail before sync-assets ever ran.
Fix: inner _say() helper that falls back to
text.encode(sys.stdout.encoding, errors="replace")
when print() raises UnicodeEncodeError. Glyphs degrade to '?' on
ASCII / cp1252 consoles; utf-8 consoles are unaffected. Verified the
full build pipeline runs to completion with PYTHONIOENCODING=cp1252.
Scoped tightly to _build_web_ui (the function this PR already touches);
other call sites in the codebase with the same risk are out of scope.
Three Windows-only bugs in the web-dashboard build path. Each is small,
scoped, and verified end-to-end on Windows 11 — including under a stock
cmd.exe / PowerShell console with its default cp1252 encoding.
1. `sync-assets` shells out to Unix-only commands
web/package.json hard-codes `rm -rf … && cp -r …`. Neither exists on
Windows cmd.exe. `hermes_cli/main.py::_build_web_ui` runs npm via
subprocess (which on Windows defaults to cmd.exe), so the prebuild
hook crashed before Vite ever ran and the dashboard never built.
Fix: web/scripts/sync-assets.mjs — ~20 lines of Node using fs.rmSync
+ fs.cpSync (stdlib, Node >= 16.7). No new deps, identical behavior
on POSIX and Windows.
2. Build failures were silent
_build_web_ui ran both subprocess calls with capture_output=True and
never relayed the captured buffers on failure. Users saw 'Web UI
build failed' and nothing else — no stdout, no stderr, no hint that
the real problem was 'rm is not recognized'.
Fix: inner _relay() helper that decodes and prints stdout + stderr
(utf-8, errors='replace') whenever a step returns non-zero. Replaces
the existing stderr_tail-only relay on the build path; success path
is unchanged. (stderr_tail is preserved for the stale-dist fallback
branch added by #23817.)
Salvaged from #13368 by @johnisag onto current main. Conflict
resolution preserves main's improvements:
- _run_npm_install_deterministic() (replaces bare subprocess.run for
npm install)
- npm-build retry-after-sleep for Windows boot-time races (#23817)
- stale-dist fallback for non-interactive callers (#23817)
Closes#25073, #13368.
Follow-up to snav's PR #25463 contribution: flip default to on, broaden
scope so backfill fires whenever require_mention gates the bot (not just
shared-session channels).
Why:
- The mention-gate creates a session-transcript gap regardless of whether
the channel is shared or per-user. In per-user sessions, Alice's session
is still missing other participants' messages and her own pre-mention
messages — backfill fills both gaps.
- Threads naturally scope to thread-only history because discord.py's
channel.history() on a thread returns only that thread's messages.
- DMs still skip — every DM triggers the bot, so the session transcript
is already complete.
Changes:
- hermes_cli/config.py: discord.history_backfill default → true
- gateway/platforms/discord.py: drop the _is_shared gate, keep _is_dm
skip and _needed_mention gate; env var DISCORD_HISTORY_BACKFILL
default → 'true'
- cli-config.yaml.example + website docs: update defaults and prose;
add the DISCORD_HISTORY_BACKFILL / _LIMIT env var rows that were
documented in the PR description but missing from the env-var table
- tests/gateway/test_discord_free_response.py:
- flip test_discord_per_user_channel_does_not_backfill →
test_discord_per_user_channel_backfills_too (new behavior)
- add test_discord_dm_does_not_backfill (DM skip is invariant)
- give FakeThread a no-op history() so existing thread tests don't hit
a fake discord.Forbidden when backfill now fires on threads too
Tests: 160/160 in target files; 400/400 across all tests/gateway/ -k discord.
Adds optional channel-context backfill for Discord shared-channel sessions
so the agent can see recent messages it missed between its own turns
(typically when require_mention=true filters out most traffic).
Previously the agent only saw the @mention message that triggered it, which
led to disorienting replies in active multi-user channels where the
conversation context was invisible. With backfill enabled, a configurable
number of recent messages are fetched per-turn and prepended to the trigger
message as a context block, kept separate from sender-prefix logic so
attribution remains clean.
This re-opens the work from #13063 (approved by @OutThisLife on 2026-04-20,
closed when I closed the branch to address the simpolism:main head-branch
issue plus an ordering bug I caught later in live use). Filing against the
freshly-rewritten problem statement in #13054 so the design is grounded in
the failure mode rather than the implementation shape.
The implementation follows the **push-mode last-self-anchored** design from
the two options laid out in #13054. See the issue for the trade-off
discussion vs pull-mode (#13120 was an earlier closed PR using that shape).
Treating this as a reference implementation — happy to rewrite as
last-trigger anchoring or as a hybrid with #13120 if maintainers prefer.
Changes:
- gateway/platforms/discord.py:
- new `_discord_history_backfill()` / `_discord_history_backfill_limit()`
helpers (config.extra > env > default), mirroring the existing
`_discord_require_mention()` shape
- new `_fetch_channel_context()` that scans `channel.history()` backwards
from the trigger to the bot's last message (or limit), formats as
`[Recent channel messages] / [name] msg / ...`, respects DISCORD_ALLOW_BOTS,
skips system messages
- per-channel `_last_self_message_id` cache to narrow the fetch window
on hot paths (avoids full history scan when the bot has spoken recently)
- **IMPORTANT**: passes `oldest_first=False` explicitly to `channel.history()`.
discord.py 2.x silently flips the default to True when `after=` is supplied,
which would select the EARLIEST N messages after our last response instead
of the LATEST N before the trigger. In high-traffic windows this would
return stale tool traces and drop the actual final answer the user is
asking about. See regression test below. Caught in live use during a
Codex tool-trace burst on May 13 2026.
- gateway/config.py: discord_history_backfill + discord_history_backfill_limit
settings + yaml→env bridge
- gateway/platforms/base.py: channel_context field on MessageEvent
- gateway/run.py: prepend channel_context after sender-prefix so the
[sender name] tag applies to the trigger message alone, not to the backfill
- hermes_cli/config.py: defaults for new discord.history_backfill and
discord.history_backfill_limit keys
- cli-config.yaml.example: documented defaults
- tests/gateway/test_discord_free_response.py: 7 new tests covering
cold-start backfill, self-message stop boundary, other-bot filtering,
cache hot-path narrowing, stale-cache fallback, shared-channel +
per-user backfill paths, and the ordering regression test
(`test_fetch_channel_context_cache_uses_latest_window_when_after_set`)
- tests/gateway/test_config.py: yaml→env bridge tests
- tests/gateway/test_session.py: prefix-order edge cases
- website/docs/user-guide/messaging/discord.md: env vars + config keys +
usage docs
Tested on Ubuntu 24.04 — empirically validated in my own multi-bot Discord
research server for the past three weeks.
Fixes#13054
Supersedes #13063 (closed)
Adds 'hermes proxy start' — a local HTTP server that lets external apps
(OpenViking, Karakeep, Open WebUI, ...) use a Hermes-managed provider
subscription as their LLM endpoint. The proxy attaches the user's real
OAuth-resolved credentials to each forwarded request, refreshing them
automatically; the client can send any bearer (it gets stripped).
Ships with one adapter — Nous Portal. The UpstreamAdapter ABC and
registry in hermes_cli/proxy/adapters/ are designed for additional
OAuth providers to plug in by name without server changes.
Commands:
hermes proxy start [--provider nous] [--host 127.0.0.1] [--port 8645]
hermes proxy status
hermes proxy providers
Allowed Portal paths: /v1/chat/completions, /v1/completions,
/v1/embeddings, /v1/models. Anything else returns 404 with a clear
error pointing at the allowed list.
aiohttp is gated like gateway/platforms/api_server.py (try-import,
clean runtime error if missing). No new core dependency.
Tests: 24 unit tests + 1 separate E2E that spawns the real subprocess
and verifies the upstream receives the right bearer with the client's
header stripped.
Pyproject's [all] extra was slimmed down in May 2026 — ~20 optional
backends moved to tools/lazy_deps.py and only install on first use.
hermes update runs uv pip install -e .[all] which doesn't touch any of
them, so pin bumps in LAZY_DEPS (CVE response, transitive fixes) were
silently ignored on already-activated backends.
Two changes:
1. _is_satisfied() now parses the spec and checks the installed version
against the constraint via packaging.specifiers. Previously it
returned True the moment the package name was importable, which made
ensure() a name-presence gate rather than a version-pin gate.
2. New active_features() / refresh_active_features() pair: lists every
feature with at least one of its packages currently installed, then
re-runs ensure() on each. Refresh is invoked at the end of
_cmd_update_impl, right after the [all] install completes. Cold
backends (never activated) stay quiet — no churn for them.
Output during update is one summary block:
→ Refreshing 4 active lazy backend(s)...
↑ 1 refreshed: provider.anthropic
✓ 3 already current
or
⚠ memory.honcho failed to refresh: <pip stderr>
Failures never raise out of update — backends keep their previously-
installed version and we tell the user to rerun once upstream is fixed.
security.allow_lazy_installs=false is honored: features get marked
"skipped" with the reason shown.
Tests: 18 new unit tests covering version-aware satisfaction (exact pin,
range, extras blocks, missing package, malformed spec), active feature
discovery, and refresh status reporting. All 61 lazy_deps tests pass.
Set file mode 0600 on ~/.hermes/.env after creation in the installer and
after every write via memory_setup._write_env_vars(). This ensures only
the file owner can read/write API keys and tokens, matching standard
practice for credential files (.netrc, .aws/credentials, .ssh/config).
Fixes#25477
Before: when `OPENROUTER_API_KEY` (or `AI_GATEWAY_API_KEY`) was already
set in ~/.hermes/.env, `hermes model openrouter` / `hermes model
ai-gateway` skipped the API-key prompt entirely and jumped straight to
the model picker. Users with a broken / expired / wrong key had no way
to replace it without editing ~/.hermes/.env by hand or re-running
`hermes setup` from scratch.
Both flows now route through the existing `_prompt_api_key()` helper,
which surfaces [K]eep / [R]eplace / [C]lear when a key is already
configured — the same UX the generic API-key providers (z.ai, MiniMax,
Gemini, etc.) and the Daytona setup already use.
Follow-up to Alex-wuhu's NovitaAI provider commit. Adds:
- _pricing_cache hit/write in _fetch_novita_pricing (was missing — every
pricing fetch was re-hitting the network), mirroring the
fetch_ai_gateway_pricing pattern. force_refresh now also propagates
from get_pricing_for_provider.
- TestNovitaProvider in tests/hermes_cli/test_api_key_providers.py
covering profile load, alias resolution, registry auto-registration,
model list parity between main.py and models.py, _URL_TO_PROVIDER,
_PROVIDER_PREFIXES, context_size in _CONTEXT_LENGTH_KEYS, pricing
unit conversion, and pricing cache behavior.
- AUTHOR_MAP entry for yanglongwei06@gmail.com → @Alex-yang00.
Add NovitaAI as a first-class provider with dedicated model selection
flow, live pricing, and authoritative context length resolution.
- Register provider in PROVIDER_REGISTRY, HERMES_OVERLAYS, and all
alias/label maps (ID: novita, aliases: novita-ai, novitaai)
- Add dedicated _model_flow_novita() with 3-tier model list fallback:
Novita API → models.dev → static curated list
- Fetch live pricing from /v1/models with correct unit conversion
(input_token_price_per_m is 0.0001 USD per Mtok)
- Add Novita-specific context length resolution (step 4b) in
get_model_context_length(), prioritized over models.dev/OpenRouter
- Register api.novita.ai in _URL_TO_PROVIDER to prevent early return
from the custom-endpoint code path
- Add models.dev mapping (novita → novita-ai)
- Add default auxiliary model (deepseek/deepseek-v3-0324)
- Add NOVITA_API_KEY to test isolation (conftest.py)
- Update docs: providers page, env vars reference, CLI reference,
.env.example, README, and landing page
