The Debian/Ubuntu branch of install_node_deps() ran 'npx playwright install
--with-deps chromium' unconditionally. Playwright invokes sudo interactively
to apt-install Chromium's system libraries, which blocks the installer for
non-sudo users (systemd service accounts, unprivileged operator users) on
an unsatisfiable password prompt.
Changes:
- install.sh: gate --with-deps behind a sudo capability check on the apt
branch (matches the existing Arch/pacman branch pattern). Non-sudo users
fall back to 'npx playwright install chromium' alone and the installer
prints the exact 'sudo npx playwright install-deps chromium' command an
administrator can run separately.
- install.sh: add --skip-browser (alias --no-playwright) to skip the
Playwright step entirely for headless installs that don't need browser
automation. Mirrors the existing --no-venv / --skip-setup shape.
- installation.md: add a 'Non-Sudo / System Service User Installs' section
covering the admin/service-user split, the --skip-browser flag, and the
~/.local/bin PATH gotcha (the root cause of the 'No module named dotenv'
error users hit when running the repo source 'hermes' script with system
Python instead of the venv launcher).
- test_install_sh_browser_install.py: regression coverage for the
--skip-browser flag and the sudo-gate on the apt branch.
Reported by @ssilver in Discord.
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
setup_path() writes the user-facing hermes shim with `cat >`, which
follows existing symlinks. Older installs created
`$command_link_dir/hermes` as a symlink to `$HERMES_BIN`
(`venv/bin/hermes`), so re-running install.sh stomped the pip entry
point with a bash shim that exec'd itself in an infinite loop.
`rm -f` the link target before writing so the shim lands at
`$command_link_dir/hermes` and the venv entry point is left intact.
Adds a regression test that reproduces the symlink-stomp end-to-end
(creates the symlink, drives the real shim-write block from setup_path,
asserts the venv pip script body survives and the shim is now a regular
file). Both new assertions fail on origin/main and pass with the fix.
Closes#21454.
Autostash creates refs/stash as a pointer to the latest stash commit, but
git stash apply/drop expect the symbolic ref format like stash@{0}, not
the raw commit SHA. Using the commit SHA causes: error: 'X is not a stash reference'
* fix(install): use `--extra all` not `--all-extras`; drop lazy-covered extras from [all]
Two coupled fixes for the Windows install hang where uv sync built
python-olm from sdist and failed on missing make.
# Root cause: --all-extras vs --extra all (credit: ethernet)
`uv sync --all-extras` installs every key in [project.optional-
dependencies], bypassing the curated [all] extra entirely. So even
when [all] excluded [matrix], [rl], [yc-bench], etc., the installer
pulled them anyway because they were still defined as extras. On
Windows that meant python-olm (no wheel, needs make to build from
sdist) and the install died there.
The right flag is `--extra all` — install just the [all] extra's
contents, respecting curation. Empirically verified via dry-run:
--all-extras: pulls python-olm, mautrix, ctranslate2, onnxruntime,
atroposlib, tinker, wandb, modal, daytona, vercel,
python-telegram-bot, discord.py, slack-bolt,
dingtalk-stream, lark-oapi, anthropic, boto3,
edge-tts, elevenlabs, exa-py, fal-client, faster-
whisper, firecrawl-py, honcho-ai, parallel-web
--extra all: pulls none of those — just [all]'s curated set
Dockerfile already uses `--extra all` (with comment explaining the
gotcha) — knowledge existed; the gap was install.sh / install.ps1 /
setup-hermes.sh.
Sites fixed: scripts/install.sh L1118, scripts/install.ps1 L809,
setup-hermes.sh L245.
# Companion fix: drop lazy-covered extras from [all]
`tools/lazy_deps.py` already covers anthropic, bedrock, exa,
firecrawl, parallel-web, fal, edge-tts, elevenlabs, modal, daytona,
vercel, all messaging platforms (telegram/discord/slack/matrix/
dingtalk/feishu), honcho, and faster-whisper. They were ALSO in
[all], which defeats the whole point of lazy-install — fresh
installs eager-pulled them and inherited whatever was broken
upstream (the matrix → python-olm → no Windows wheel chain being
the proximate symptom).
[all] now contains only what genuinely can't be lazy-installed:
cron, cli, dev, pty, mcp, homeassistant, sms, acp, google, web,
youtube. Same trim applied to [termux-all]. New regression test
asserts the contract: every extra in LAZY_DEPS must NOT also appear
in [all].
# Companion fix: surface uv progress + errors
setup-hermes.sh's hash-verified path swallowed uv's stderr to a
tempfile, identical to the install.sh bug fixed in PR #24504. Same
fix applied: stream stderr through directly so users see live
progress instead of staring at a frozen prompt.
# Files
- pyproject.toml: trim [all] and [termux-all] to non-lazy extras only.
- scripts/install.sh: --all-extras → --extra all; trim _ALL_EXTRAS /
_PYPI_EXTRAS to match.
- scripts/install.ps1: --all-extras → --extra all; trim $allExtras /
$pypiExtras to match.
- setup-hermes.sh: --all-extras → --extra all; stream stderr.
- tests/test_project_metadata.py: invert matrix-in-[all] assertion;
add lazy-coverage contract test.
- uv.lock: regenerated.
# Validation
5/5 metadata tests pass. 37/37 in update_autostash + tool_token_
estimation. `uv lock --check` passes. Empirical dry-run confirms
`--extra all` excludes python-olm + RL chain on the new lockfile.
* fix(install): parse [all] from pyproject.toml instead of mirroring it
ethernet's review point: the previous patch left two hand-mirrored
copies of [all]'s contents (in install.sh's $_ALL_EXTRAS and
install.ps1's $allExtras). That guarantees future drift the next
time pyproject.toml's [all] changes.
Now both scripts parse pyproject.toml at install time using stdlib
tomllib (Python 3.11+, which the bootstrap step already requires).
Single source of truth. The only purpose of the parsed list is to
build the 'Tier 2: [all] minus broken extras' fallback spec — so we
parse, filter against $brokenExtras, and rebuild the .[a,b,c] spec.
Also: removed redundant fallback tiers.
Before: Tier 1 [all]
Tier 2 [all] minus broken
Tier 3 PyPI-only extras (no git deps)
Tier 4 [web,mcp,cron,cli,messaging,dev]
Tier 5 .
After: Tier 1 [all]
Tier 2 [all] minus broken
Tier 3 .
Tier 3 (PyPI-only) and Tier 4 (dashboard+core) used to dodge the [rl]
git+sdist deps and the [matrix] python-olm build. Both are no longer
in [all] post-2026-05-12 lazy-install migration, so the carve-out
tiers had no remaining content. Tier 4 also referenced [messaging],
which is now lazy-installed — the hardcoded fallback was actually
inconsistent with the new policy.
Defensive fallback: if tomllib parse fails (corrupted pyproject,
unexpected schema), Tier 2 collapses to '.[all]' (same as Tier 1) so
the broken-extras path becomes a no-op rather than crashing.
* fix(gateway): hide Matrix from setup picker on Windows
Matrix is the one messaging platform that has no working install path
on Windows: [matrix] -> mautrix[encryption] -> python-olm, which has
Linux-only wheels and needs make + libolm to build from sdist. The
[all] cleanup in this PR keeps mautrix out of fresh installs, but a
user who picked Matrix in 'hermes setup gateway' would still walk
into the same sdist build failure when the wizard tried to install
the extra.
Hide the option at the picker so users never get the chance to try.
The gate lives in _all_platforms() — single source of truth for the
setup wizard, the curses gateway-config menu, and any future picker.
Adapter loading at runtime is intentionally NOT gated: users who
already have MATRIX_* env vars set (e.g. config copied from a Linux
install) keep working if they somehow have python-olm available.
This is the lowest-friction fix — picker visibility only.
Tests cover linux/darwin/win32 and verify other platforms aren't
collateral damage.
The c1eb2dcda tiered installer made two install paths look frozen on
slow networks or broken environments because both swallowed the
underlying tool's stderr.
scripts/install.sh, setup-hermes.sh:
curl -LsSf https://astral.sh/uv/install.sh | sh 2>/dev/null
printed only '✗ Failed to install uv' on failure with no diagnostic.
Common real causes (glibc mismatch on old distros, corp proxy / TLS
interception, missing curl, ~/.local/bin not writable, disk full)
were invisible. Also: piping curl into sh masks curl failures under
set -e (no pipefail) — sh exits 0 on empty stdin, so a network error
succeeded silently.
Fix: download installer to a tempfile first, then run it. Capture
curl + installer output to a log; on failure, indent and print it.
scripts/install.sh hash-verified tier:
uv sync --all-extras --locked 2>"$(mktemp)" silenced uv's progress
output, making a fresh-venv install (~50 transitives including
torch-class deps) look hung for 1-5 minutes — users see 'Trying tier:
hash-verified (uv.lock) ...' and assume it's frozen. The mktemp
substitution also wasn't saved to a variable, so the uv error on
failure was unreachable.
Fix: stream uv's stderr directly so users see live 'Resolved N /
Prepared / Installed' progress. Print an upfront note that the first
run takes 1-5 minutes.
* feat(security): supply-chain advisory checker + lazy-install framework + tiered install fallback
Three coordinated mitigations for the Mini Shai-Hulud worm hitting
mistralai 2.4.6 on PyPI (2026-05-12) and for the next single-package
compromise that follows.
# What this PR makes true
1. Users with the poisoned mistralai 2.4.6 in their venv get a loud
detection banner with copy-pasteable remediation steps the moment
they run hermes (and on every gateway startup).
2. One quarantined / yanked PyPI package can no longer silently demote
a fresh install to 'core only' — the installer keeps every other
extra and tells the user which tier landed.
3. Future opt-in backends (Mistral, ElevenLabs, Honcho, etc.) can
lazy-install on first use under a strict allowlist, instead of
eagerly pulling everything at install time.
# Detection: hermes_cli/security_advisories.py
- ADVISORIES catalog (one entry currently: shai-hulud-2026-05 for
mistralai==2.4.6). Adding the next one is a single dataclass.
- detect_compromised() uses importlib.metadata.version() — no pip
dependency, works in uv venvs that lack pip.
- Banner cache (~/.hermes/cache/advisory_banner_seen) rate-limits
the startup banner to once per 24h per advisory.
- Acks persisted to security.acked_advisories in config.yaml; never
re-banner after ack.
- Wired into:
* hermes doctor — runs first, prints full remediation block
* hermes doctor --ack <id> — dismisses an advisory
* cli.py interactive run() and single-query branches — short
stderr banner pointing at hermes doctor
* gateway/run.py startup — operator-visible warning in gateway.log
# Lazy-install framework: tools/lazy_deps.py
- LAZY_DEPS allowlist maps namespaced feature keys (tts.elevenlabs,
memory.honcho, provider.bedrock, etc.) to pip specs.
- ensure(feature) installs missing deps in the active venv via the
uv → pip → ensurepip ladder (matches tools_config._pip_install).
- Strict spec safety regex rejects URLs, file paths, shell metas,
pip flag injection, control chars — only PyPI-by-name accepted.
- Gated on security.allow_lazy_installs (default true) plus the
HERMES_DISABLE_LAZY_INSTALLS env var for restricted/audited envs.
- Migrated three backends as proof of pattern:
* tools/tts_tool.py — _import_elevenlabs() calls ensure first
* plugins/memory/honcho/client.py — get_honcho_client lazy-installs
* tts.mistral / stt.mistral entries pre-registered for when PyPI
restores mistralai
# Installer fallback tiers
scripts/install.sh, scripts/install.ps1, setup-hermes.sh:
- Centralised _BROKEN_EXTRAS list (currently: mistral). Edit one
array when a transitive breaks; users keep every other extra.
- New 'all minus known-broken' tier between [all] and the existing
PyPI-only-extras tier. Only kicks in when [all] fails resolve.
- All three tiers explicit: every fallback announces which tier
landed and prints a re-run hint when not on Tier 1.
- install.ps1 and install.sh both regenerate their tier specs from
the same _BROKEN_EXTRAS array so updates stay in sync.
Side effect: install.ps1 Tier 2 spec previously hardcoded 'mistral'
in its extra list — bug fixed by the refactor (mistral is filtered
out).
# Config
hermes_cli/config.py — DEFAULT_CONFIG.security gains:
- acked_advisories: [] (advisory IDs the user has dismissed)
- allow_lazy_installs: True (security gate for ensure())
No config version bump needed — both keys nest under existing
security: block, and load_config's deep-merge picks up DEFAULT_CONFIG
defaults for users with older configs.
# Tests
tests/hermes_cli/test_security_advisories.py — 23 tests covering:
- detect_compromised matches/non-matches, wildcard frozenset
- ack persistence, idempotence, blank rejection, config-failure path
- banner cache rate limiting + 24h re-banner + ack-stops-banner
- short_banner_lines / full_remediation_text / render_doctor_section /
gateway_log_message
- shipped catalog well-formedness invariant
tests/tools/test_lazy_deps.py — 40 tests covering:
- spec safety: 11 safe parametrized + 18 unsafe parametrized
- allowlist: unknown-feature rejection, namespace.name shape,
every shipped spec passes the safety regex
- security gating: config flag, env var, default, fail-open
- ensure() happy/sad paths: already-satisfied, install success,
pip stderr surfaced on failure, install-succeeds-but-still-missing
- is_available, feature_install_command
Combined: 63 new tests, all passing under scripts/run_tests.sh.

* build(deps): pin every direct dep to ==X.Y.Z (no ranges)
Companion to the supply-chain advisory work: replace every >=/</~= range
in pyproject.toml's [project.dependencies] and [project.optional-dependencies]
with an exact ==X.Y.Z pin sourced from uv.lock.
Why: ranges allow PyPI to ship a fresh version of any direct dep at any
time without a code review on our side. With ranges, the malicious
mistralai 2.4.6 release would have been pulled by every fresh
'pip install -e .[all]' for the hours between upload and PyPI's
quarantine — exactly the install window we got hit on. Exact pins close
that window: the only way a new package version reaches a user is via
an intentional update on our end.
What the user-facing change is: nothing, behavior-wise. Every package
resolves to the same version it was already resolving to via uv.lock —
the pins just remove the resolver's freedom to pick a different one.
Cost: any user installing Hermes alongside another package that requires
a newer pin gets a resolver conflict. Acceptable for our isolated-venv
install path; documented in the new comment block.
Build-system requires line (setuptools>=61.0) is intentionally left
as a range — pinning the build backend would block fresh pip from
bootstrapping the build on architectures where that exact wheel isn't
available.
mistral extra (mistralai==2.3.0) is pinned but stays out of [all]
(per PR #24205). 'uv lock' regeneration will fail until PyPI restores
mistralai; lockfile regeneration is gated behind that, NOT on every PR.
LAZY_DEPS in tools/lazy_deps.py also moved to exact pins so the lazy-
install pathway can never resolve a different version than the one
declared in pyproject.toml.
Validation:
- Cross-checked all 77 pinned direct deps in pyproject.toml against
uv.lock — every pin matches the resolved version exactly.
- Cross-checked all LAZY_DEPS specs against uv.lock — same.
- 'uv pip install -e .[all] --dry-run' resolves 205 packages cleanly.
- tests/tools/test_lazy_deps.py + tests/hermes_cli/test_security_advisories.py
→ 63/63 passing (every shipped spec passes the safety regex).
- Doctor + TTS + transcription targeted suite → 146/146 passing.
* build(deps): hash-verify transitives via uv.lock; remove unresolvable [mistral] extra
You asked: 'what about the dependencies the dependencies rely on?' —
correctly noting that exact-pinning direct deps in pyproject.toml does
NOT cover the transitive graph. `pip install` and `uv pip install` both
re-resolve transitives fresh from PyPI at install time, so a compromised
transitive (e.g. `httpcore` if it got worm-poisoned tomorrow) would
still hit our users even with every direct dep exact-pinned.
# What this commit fixes
1. **Both real installer scripts now prefer `uv sync --locked` as Tier 0.**
uv.lock records SHA256 hashes for every transitive — a compromised
package with a different hash gets REJECTED. Falls through to the
existing `uv pip install` cascade if the lockfile is missing or
stale, with a loud warning that the fallback path does NOT
hash-verify transitives. Previously only `setup-hermes.sh` (the dev
path) used the lockfile; `scripts/install.sh` and `scripts/install.ps1`
(the paths fresh users actually run) skipped it.
2. **Removed the `[mistral]` extra entirely.** The `mistralai` PyPI
project is fully quarantined right now — every version returns 404,
so any pin we wrote was unresolvable, which broke `uv lock --check`
in CI. Restoration is documented in pyproject.toml as a 5-step
checklist (verify, re-add extra, re-enable in 4 modules, regenerate
lock, optionally re-add to [all]).
3. **Regenerated uv.lock.** 262 packages, mistralai/eval-type-backport/
jsonpath-python pruned. `uv lock --check` now passes.
# Defense-in-depth view
| Layer | Where | Protects against |
|----------------------------|-------------------|-------------------------------------------|
| Exact pins in pyproject | direct deps | new mistralai 2.4.6-style direct compromise |
| uv.lock + `--locked` install | transitive graph | transitive worm injection |
| Tier-0 hash-verified path | install.sh / .ps1 | actually USE the lockfile in fresh installs |
| `uv lock --check` CI gate | every PR | drift between pyproject and lockfile |
| `hermes_cli/security_advisories.py` | runtime | cleanup for users who already got hit |
The exact pinning + hash verification together close the supply-chain
gap. Without the lockfile path, exact pins alone are theater.
# Validation
- `uv lock --check` → passes (262 packages resolved, no drift).
- `bash -n` on install.sh + setup-hermes.sh → OK.
- 209/209 tests passing across new + adjacent test files
(test_lazy_deps.py, test_security_advisories.py, test_doctor.py,
test_tts_mistral.py, test_transcription_tools.py).
- TOML parse OK.
* chore: remove community announcement drafts (PR body covers it)
* build(deps): lazy-install every opt-in backend (anthropic, search, terminal, platforms, dashboard)
Extends the lazy-install framework to cover everything that's not used by
every hermes session. Base install drops from ~60 packages to 45.
Moved out of core dependencies = []:
- anthropic (only when provider=anthropic native, not via aggregators)
- exa-py, firecrawl-py, parallel-web (search backends; only when picked)
- fal-client (image gen; only when picked)
- edge-tts (default TTS but still optional)
New extras in pyproject.toml: [anthropic] [exa] [firecrawl] [parallel-web]
[fal] [edge-tts]. All added to [all].
New LAZY_DEPS entries: provider.anthropic, search.{exa,firecrawl,parallel},
tts.edge, image.fal, memory.hindsight, platform.{telegram,discord,matrix},
terminal.{modal,daytona,vercel}, tool.dashboard.
Each import site now calls ensure() before importing the SDK. Where the
module had a top-level try/except (telegram, discord, fastapi), the
graceful-fallback pattern was extended to lazy-install on first
check_*_requirements() call and re-bind module globals.
Updated test_windows_native_support.py tzdata check from snapshot
(>=2023.3 literal) to invariant (any version + win32 marker).
Validation:
- Base install: 45 packages (was ~60); 6 newly-extracted packages absent
- uv lock --check: passes (262 packages, no drift)
- 209/209 lazy_deps + advisory + doctor + tts/transcription tests passing
- py_compile clean on all 12 modified modules
The Termux update path (PR #22814) prebuilds psutil from a marker-patched
sdist so 'platform android is not supported' doesn't kill it. The same
psutil setup.py error blocks fresh installs via scripts/install.sh — only
the update path was wired up. Without this, a brand-new Termux user can't
get past the very first 'pip install -e .[termux-all]' call.
- New scripts/install_psutil_android.py — standalone version of the same
patcher hermes_cli/main.py uses, callable from bash.
- scripts/install.sh detects sys.platform == 'android' and runs the
patcher before pip install.
- TODO note added to both copies pointing at upstream
https://github.com/giampaolo/psutil/pull/2762; remove both when that
ships.
Note: we keep psutil as a base dep on Android (do not adopt the proposed
sys_platform != 'android' marker in pyproject). Removing it would crash
five unguarded 'import psutil' sites at runtime
(tools/code_execution_tool.py, tools/tts_tool.py, tools/process_registry.py
(2x), gateway/platforms/whatsapp.py).
When the installer is run via , uv resolves config file
paths against the process owner's (root) home directory rather than the
effective user's, causing a Permission denied error when trying to read
/root/uv.toml.
Setting UV_NO_CONFIG=1 prevents uv from discovering any config files
(uv.toml, pyproject.toml) during installation, which is the correct
behavior for a bootstrap script that manages its own environment.
Fixes#21269
The contributor's PR (#16750) scoped the fix to run_setup_wizard() and
explicitly punted the two sibling sites. Both have the identical
[ -e /dev/tty ] pattern followed by a < /dev/tty redirect and crash in
Docker the same way:
- scripts/install.sh:732 install_system_packages() -- apt sudo prompt
fallback. sudo ... < /dev/tty dies with the same ENXIO.
- scripts/install.sh:1395 maybe_start_gateway() -- gateway-install gate,
same function path as the wizard reproducer.
Fix both with the same (: </dev/tty) 2>/dev/null probe, and parametrize
the regression test over all three gated functions so any future
regression is caught regardless of which site breaks.
In Docker builds the `/dev/tty` device node is present in the mount
namespace, so `[ -e /dev/tty ]` returns true — but opening it fails
with `ENXIO: No such device or address`. Under the old gate the
"no terminal available" skip never triggered, the setup wizard ran,
and the build aborted a few lines later when bash tried `< /dev/tty`:
/tmp/install.sh: line 1347: /dev/tty: No such device or address
Replace the existence check with `(: </dev/tty) 2>/dev/null`, which
actually attempts to open /dev/tty in a subshell. The probe succeeds
when piped from `curl | bash` on a real terminal (the wizard's intended
use case) and fails cleanly in Docker build / CI contexts so the skip
kicks in before the redirect can crash.
Add a regression test that statically asserts run_setup_wizard does not
gate on the bare existence check and that the open-based probe is in
place.
Fixes#16746.

* fix(install): add /usr/local/bin PATH guard for RHEL root non-login shells
The FHS-layout branch assumed /usr/local/bin is on PATH for every
standard shell. That holds for login shells (via /etc/profile's
pathmunge) but breaks on RHEL/CentOS/Rocky/Alma 8+ root in non-login
interactive shells (su, sudo -s, tmux panes, some web terminals) —
/etc/bashrc does not add /usr/local/bin and /root/.bash_profile
doesn't either. Result: hermes command links to /usr/local/bin/hermes
but the user has to type the absolute path each time.
Probe a fresh 'bash -i -c' (non-login interactive, matching the user
scenario) after symlinking. If hermes isn't resolvable, append an
idempotent PATH guard to /root/.bashrc and /root/.bash_profile, same
grep pattern already used by the ~/.local/bin branch below. No change
on distros where /usr/local/bin is already inherited.
* fix(update): repair RHEL root PATH on hermes update
Existing RHEL/CentOS/Rocky/Alma root installs won't be repaired by the
install.sh fix alone because 'hermes update' is an in-place git pull, not
a rerun of install.sh. Port the same probe + idempotent .bashrc write
into cmd_update so affected users get fixed automatically on next update.
_ensure_fhs_path_guard() runs after 'Update complete!':
- Linux + root + FHS-layout install (command at /usr/local/bin/hermes) only
- Probe: env -i bash -i -c 'command -v hermes' — fresh non-login interactive
shell, same scenario the user reports
- On failure, append PATH guard to /root/.bashrc and /root/.bash_profile,
skipping if any uncommented PATH line already mentions /usr/local/bin
- Silent no-op on macOS, non-root, legacy layout, or shells that already
resolve hermes
Root installs on Linux now put the code at /usr/local/lib/hermes-agent and
the hermes command at /usr/local/bin/hermes. HERMES_HOME (~/.hermes) stays
state-only. Matches Claude Code / Codex CLI / OpenClaw, keeps Docker
bind-mounted /root/ volumes lean, and puts the command on every shell's
default PATH without touching shell RC files.
- Non-root users and macOS root: unchanged
- Existing root installs at $HERMES_HOME/hermes-agent: preserved in-place
(detected via .git dir) — no auto-migration, no breakage
- Explicit --dir / $HERMES_INSTALL_DIR: always wins, never overridden
- Termux: unchanged (package manager manages /data/data/...)
Requested by @souly9999 (Discord). Our own Dockerfile already uses this
split (code at /opt/hermes, data at /opt/data volume); the user-install
path now matches.
Cherry-picked from PR #10019 by @PStarH.
On macOS, uv stores Python in ~/Library/Application Support/uv/...
which contains a space. Unquoted $PYTHON_PATH and $UV_CMD caused
word-splitting under set -e, silently aborting install.sh.
Quotes all variable expansions in check_python():
- "$PYTHON_PATH" in command invocations
- "$UV_CMD" in uv calls
- Outer quotes on $(...) assignments
Closes#10009
Remove eager npm install of @whiskeysockets/baileys during
install.sh, install.ps1, and Docker build. The bridge deps are
already installed on-demand by `hermes whatsapp` (Step 4 checks
for node_modules and runs npm install if missing), so there is no
need to pay the cost at initial install for users who never use
WhatsApp.
The helper used ${var,,} (bash 4+ lowercase parameter expansion) and
[[ =~ ]], which fail on macOS default /bin/bash (3.2.57) with:
bash: ${default,,}: bad substitution
With 'set -e' at the top of the script, that aborts the whole
installer for macOS users who don't have a newer bash on PATH.
Replace the lowercase expansions with POSIX-style case patterns
(`[yY]|[yY][eE][sS]|...`) that behave identically and parse cleanly
on bash 3.2. Verified with a 15-case behavior test on both bash 3.2
and bash 5.2 — all pass.
* fix: show correct env var name in provider API key error (#9506)
The error message for missing provider API keys dynamically built
the env var name as PROVIDER_API_KEY (e.g. ALIBABA_API_KEY), but
some providers use different names (alibaba uses DASHSCOPE_API_KEY).
Users following the error message set the wrong variable.
Fix: look up the actual env var from PROVIDER_REGISTRY before
building the error. Falls back to the dynamic name if the registry
lookup fails.
Closes#9506
* fix: five HERMES_HOME profile-isolation leaks (#5947)
Bug A: Thread session_title from session_db to memory provider init kwargs
so honcho can derive chat-scoped session keys instead of falling back to
cwd-based naming that merges all gateway users into one session.
Bug B: Replace 14 hardcoded ~/.hermes/skills/ paths across 10 skill files
with HERMES_HOME-aware alternatives (${HERMES_HOME:-$HOME/.hermes} in
shell, os.environ.get('HERMES_HOME', ...) in Python).
Bug C: install.sh now respects HERMES_HOME env var and adds --hermes-home
flag. Previously --dir only set INSTALL_DIR while HERMES_HOME was always
hardcoded to $HOME/.hermes.
Bug D: Remove hardcoded ~/.hermes/honcho.json fallback in resolve_config_path().
Non-default profiles no longer silently inherit the default profile's honcho
config. Falls through to ~/.honcho/config.json (global) instead.
Bug E: Guard _edit_skill, _patch_skill, _delete_skill, _write_file, and
_remove_file against writing to skills found in external_dirs. Skills
outside the local SKILLS_DIR are now read-only from the agent's perspective.
Closes#5947
Fish users' $SHELL is /usr/bin/fish, which fell into the '*' case and
incorrectly wrote 'export PATH=...' to ~/.bashrc and ~/.zshrc — neither
of which fish reads.
- setup_path(): add fish) case that writes fish_add_path to
~/.config/fish/config.fish (fish-compatible PATH syntax)
- setup_path(): skip ~/.profile for fish (not sourced by fish)
- print_success(): show correct reload instruction for fish:
source ~/.config/fish/config.fish

Playwright's --with-deps flag only supports apt-based dependency
installation. The install script previously ran it on all non-Arch
systems, failing silently on Gentoo, Fedora, openSUSE, and others.
- Restrict --with-deps to known apt-based distributions
- Add explicit guidance for RPM-based (dnf) and zypper-based systems
- Show visible warnings instead of suppressing failures with || true
- Correct misleading comment that claimed dnf/zypper support
Fixes#6865
- print_success() hardcoded 'source ~/.bashrc' regardless of user's shell
- On macOS (default zsh), ~/.bashrc doesn't exist, leaving users unable to
find the hermes command after install
- Now detects $SHELL and shows the correct file (zshrc/bashrc)
- Also captures .[all] install failure output instead of silencing with
2>/dev/null, so users can diagnose why full extras failed
Drop the mini-swe-agent git submodule. All terminal backends now use
hermes-agent's own environment implementations directly.
Docker backend:
- Inline the `docker run -d` container startup (was 15 lines in
minisweagent's DockerEnvironment). Our wrapper already handled
execute(), cleanup(), security hardening, volumes, and resource limits.
Modal backend:
- Import swe-rex's ModalDeployment directly instead of going through
minisweagent's 90-line passthrough wrapper.
- Bake the _AsyncWorker pattern (from environments/patches.py) directly
into ModalEnvironment for Atropos compatibility without monkey-patching.
Cleanup:
- Remove minisweagent_path.py (submodule path resolution helper)
- Remove submodule init/install from install.sh and setup-hermes.sh
- Remove mini-swe-agent from .gitmodules
- environments/patches.py is now a no-op (kept for backward compat)
- terminal_tool.py no longer does sys.path hacking for minisweagent
- mini_swe_runner.py guards imports (optional, for RL training only)
- Update all affected tests to mock the new direct subprocess calls
- Update README.md, CONTRIBUTING.md
No functionality change — all Docker, Modal, local, SSH, Singularity,
and Daytona backends behave identically. 6093 tests pass.
litellm 1.82.7/1.82.8 contained a credential stealer (.pth auto-exec
payload). PyPI quarantined the entire package, blocking all fresh
hermes-agent installs since litellm was listed as a hard dependency.
These three deps (litellm, typer, platformdirs) are only used by the
mini-swe-agent submodule, which has its own pyproject.toml and manages
its own dependencies. They were redundantly duplicated in hermes-agent's
pyproject.toml.
Also fixes install.sh to not print 'mini-swe-agent installed' on
failure, and updates warning messages in both install scripts to clarify
that only Docker/Modal backends are affected — local terminal is
unaffected.

On macOS, zsh users may not have ~/.zshrc if they haven't customized
their shell yet. The installer would silently fail to add ~/.local/bin
to PATH, causing 'hermes: command not found' after installation.
- Check ~/.zprofile as fallback for zsh users (macOS login shell config)
- Create ~/.zshrc if neither config file exists

Fresh installs without pull.rebase configured hit a git error when
running hermes update because git doesn't know how to reconcile
divergent branches. --ff-only is the right strategy: it works for the
normal case (local branch is behind remote) and fails cleanly if the
user somehow has local commits, rather than silently rebasing them.
* fix: Anthropic OAuth compatibility — Claude Code identity fingerprinting
Anthropic routes OAuth/subscription requests based on Claude Code's
identity markers. Without them, requests get intermittent 500 errors
(~25% failure rate observed). This matches what pi-ai (clawdbot) and
OpenCode both implement for OAuth compatibility.
Changes (OAuth tokens only — API key users unaffected):
1. Headers: user-agent 'claude-cli/2.1.2 (external, cli)' + x-app 'cli'
2. System prompt: prepend 'You are Claude Code, Anthropic's official CLI'
3. System prompt sanitization: replace Hermes/Nous references
4. Tool names: prefix with 'mcp_' (Claude Code convention for non-native tools)
5. Tool name stripping: remove 'mcp_' prefix from response tool calls
Before: 9/12 OK, 1 hard fail, 4 needed retries (~25% error rate)
After: 16/16 OK, 0 failures, 0 retries (0% error rate)
* installer: clarify why sudo is needed at every prompt
Every sudo prompt now explicitly states what packages are being installed
and that Hermes Agent itself does not require or retain root access.
Covers system packages, build tools, and Playwright browser deps.
Add a restore prompt for interactive updates, keep the stash when the user declines, and print a post-restore warning that local changes were reapplied on top of updated code.
The tinker-atropos submodule and its heavy dependencies (atroposlib, tinker,
wandb, fastapi, uvicorn) were being installed for all users by default,
adding significant install time and disk usage for most users who don't
need RL training capabilities.
Changes:
- install.sh: Only init mini-swe-agent submodule by default; skip
tinker-atropos clone and install entirely
- install.sh: Remove --recurse-submodules from git clone (only fetches
what's needed)
- pyproject.toml: Add [rl] optional dependency group for explicit opt-in
- rl_training_tool.py: Move LOGS_DIR.mkdir() from module-level to lazy
init (_ensure_logs_dir) to avoid side effects on import
- README.md: Update contributor quick start to not auto-fetch
tinker-atropos; add RL opt-in instructions
Users who want RL training can opt in with:
git submodule update --init tinker-atropos
uv pip install -e ./tinker-atropos
Two issues fixed:
1. (Critical) hermes setup tools / hermes tools: On first-time setup,
the tool checklist showed all tools as pre-selected (from the default
hermes-cli toolset), but after confirming the selection, NO API key
prompts appeared. This is because the code only prompted for 'newly
added' tools (added = new_enabled - current_enabled), but since all
tools were already in the default set, 'added' was always empty.
Fix: Detect first-time configuration (no platform_toolsets entry in
config) and check ALL enabled tools for missing API keys, not just
newly added ones. Returning users still only get prompted for newly
added tools (preserving skip behavior).
2. install.sh: When run via curl|bash on WSL2/Ubuntu, ripgrep and ffmpeg
install was silently skipped with a confusing 'Non-interactive mode'
message. The script already uses /dev/tty for the setup wizard, but
the system package section didn't.
Fix: Try reading from /dev/tty when available (same pattern as the
build-tools section and setup wizard). Only truly skip when no
terminal is available at all (Docker build, CI).
Updated the systemd unit generation to include the virtual environment and node modules in the PATH, improving the execution context for the hermes CLI. Additionally, added support for installing Playwright and its dependencies on Arch/Manjaro systems in the install script, ensuring a smoother setup process for browser tools.
Updated the gateway setup function to provide clearer messaging when no terminal is available, enhancing user understanding of the installation process. This change ensures that users are informed to run 'hermes gateway install' later if the setup is skipped due to terminal unavailability.
Modified the setup wizard to ensure it only skips execution when no terminal is available, improving compatibility with piped installations. Additionally, updated environment variable checks to use bool() for accurate provider configuration detection, addressing potential issues with empty values in .env files.
Updated the install.sh script to set DEBIAN_FRONTEND and NEEDRESTART_MODE environment variables for non-interactive package installations on Ubuntu and Debian. This change ensures that prompts from needrestart and whiptail do not block the installation process, improving automation for system package installations.
