Round 1 of #17174 hit `nix-lockfile-check` failure. Root cause was
NOT a stale hash — the primary `nix (ubuntu-latest)` and
`nix (macos-latest)` builds passed. GitHub's Magic Nix Cache returned
HTTP 418 (rate-limited / throttled) mid-run, so the rebuild bailed
with `some outputs of '/nix/store/...-npm-deps.drv' are not valid,
so checking is not possible` — no `got:` line for the script to
extract.
The script then incorrectly treated this as 'build failed with no
hash mismatch' and exited 1, breaking the lint on every PR whenever
the cache is throttled.
Now we recognize the throttling/cache-disabled signature and skip
that entry with a warning. A real stale hash still surfaces in the
primary `.#$ATTR` build (separate CI job), so we don't lose
coverage.
`web/package-lock.json` was updated by the design-system refactor
(merged via #17007 + follow-ups: spinner / select / badges / buttons)
without bumping `nix/web.nix::npmDeps.hash`, breaking nix builds on
every PR + main since 2026-04-28T18:46.
Hash sourced from the actual `Check flake` failure output:
specified: sha256-AahWmJ9gDQ9pMPa1FYwUjYdO2mOi6JM9Mst27E0vp68=
got: sha256-+B2+Fe4djPzHHcUXRx+m0cuyaopAhW0PcHsMgYfV5VE=
Standalone single-file fix so it can land fast and clear nix on
every other open PR.
* ci(nix): auto-fix stale npm hashes on push to main
When a PR merges to main with updated package-lock.json or package.json
in ui-tui/ or web/, the new auto-fix-main job detects stale npmDepsHash
values and pushes a fix commit directly to main.
This eliminates the recurring manual hash-bump PRs (#15420, #15314,
#15272, #15244) by reusing the existing fix-lockfiles --apply pipeline.
The fix commit only touches nix/*.nix files, which are outside the push
path filter (package-lock.json / package.json), so it cannot re-trigger
itself.
Closes#15314
* fix(ci): use GitHub App token for auto-fix-main push
GITHUB_TOKEN commits are invisible to workflow triggers (GitHub's
infinite-loop prevention). The auto-fix-main job pushes directly to
main, so the fix commit never triggered downstream nix.yml verification.
Mint a short-lived token via the repo's GitHub App (daimon-nous, APP_ID
+ APP_PRIVATE_KEY secrets) so the push is treated as a real event and
nix.yml fires to verify the corrected hashes.
Tested via workflow_dispatch dry-run: app token minted successfully,
checkout with app token succeeded, fix job correctly gated.
Resolves review feedback from Bugbot (r3144569551).
* ci(nix): rename lockfile check job for required status check
Rename 'check' → 'nix-lockfile-check' so the status check name is
unambiguous when added as a required check on main.
* fix(ci): harden auto-fix-main against races, loops, and silent failures
Address adversarial review findings:
1. Race condition (#1): Job-level concurrency with cancel-in-progress
collapses back-to-back pushes; ref: main checkout always gets latest
branch state; explicit push target (origin HEAD:main).
2. Loop prevention (#2): File-whitelist check before commit aborts if
any file outside nix/{tui,web}.nix was modified, preventing
accidental self-triggering.
3. Silent infra failures (#8): nix-lockfile-check now fails explicitly
when fix-lockfiles exits without reporting stale status (catches nix
setup failures, network errors, script bugs that bypass continue-on-error).
4. Commit traceability (#11): Auto-fix commits include source SHA and
workflow run URL in the commit body.
5. Explicit push target (#12): git push origin HEAD:main instead of
bare git push.

* fix(nix): make extraPackages actually work — wire into per-user profile
#17030 deprecated extraPackages because it only set the systemd service
PATH, which the terminal backend's login-shell snapshot discards.
Instead of deprecating, fix it: set users.users.${cfg.user}.packages
so NixOS builds a per-user profile at /etc/profiles/per-user/hermes/bin.
This path is included in PATH by /etc/set-environment, which the login
shell sources, so the terminal backend's snapshot picks it up.
One line of actual logic:
users.users.${cfg.user}.packages = cfg.extraPackages;
Verified in a NixOS VM test: su - hermes -c 'which hello' resolves
to /etc/profiles/per-user/hermes/bin/hello.
Reverts the deprecation warning and docs changes from #17030, restores
extraPackages as the recommended way to give the agent extra tools.
Container mode is unaffected — extraPackages was always native-only
(the systemd path line is inside !cfg.container.enable).
* nix: clarify additive merge semantics for extraPackages user profile
---------
Co-authored-by: Siddharth Balyan <daimon@noreply.github.com>
extraPackages adds packages to the systemd service PATH, but the
terminal backend's login-shell snapshot rebuilds PATH from NixOS system
profiles, so tools added via extraPackages are invisible to terminal
commands, skills, and cron jobs — the entire use case.
Changes:
- Mark the option description as deprecated with explanation
- Emit a NixOS warning when extraPackages is non-empty, including a
ready-to-paste environment.systemPackages replacement
- Update docs: quick-reference table, plugin example, and options
reference all point to environment.systemPackages
The option still functions (non-breaking) so existing configs keep
working while users migrate.
* feat(nix): parameterize dependency-groups in python.nix
* refactor(nix): extract package to callPackage-able hermes-agent.nix
Makes the package overridable via .override{} and adds
extraPythonPackages parameter for PYTHONPATH injection.
Includes build-time collision check using PEP 503 name
canonicalization.
* feat(nix): add overlay for external NixOS consumption
External flakes can now add overlays = [ inputs.hermes-agent.overlays.default ]
to get pkgs.hermes-agent with full .override support.
* test(nix): add check for extraPythonPackages PYTHONPATH injection
Verifies wrapper has PYTHONPATH when extras provided, and
base package has no PYTHONPATH without extras.
* feat(nix): add extraPlugins option for directory-based plugins
Symlinks plugin packages into HERMES_HOME/plugins/ at activation time.
Validates plugin.yaml presence. Asserts unique plugin names at eval time.
Hermes discovers them automatically via its directory scan.
* feat(nix): add extraPythonPackages option for entry-point plugins
Overrides the hermes package with PYTHONPATH injection when
extraPythonPackages is non-empty. Plugin .dist-info directories
become visible to importlib.metadata for entry-point discovery.
Works in both native systemd and container modes.
* docs: add NixOS declarative plugin installation to nix-setup, plugins, and build-a-plugin guides
- nix-setup.md: new Plugins section with extraPlugins/extraPythonPackages
examples, overlay usage, collision checking note, options reference rows
- plugins.md: Nix row in discovery table, NixOS declarative plugins section
- build-a-hermes-plugin.md: Distribute for NixOS section after pip section
* fix: address review feedback — remove unrelated umask, fix fetchFromGitHub naming, simplify checks
- Remove accidentally introduced umask/migration changes (unrelated to plugins)
- Add pluginName helper, fix fetchFromGitHub producing name='source'
- Show name= in extraPlugins example docs
- Simplify checks.nix: use hermes-agent.override instead of re-callPackage
- Fix fragile grep shell logic in checks
* refactor: address simplify feedback — lib.getName, drop unused inputs', Python list for extras
- Use lib.getName instead of custom pluginName helper
- Drop unused inputs' from checks.nix perSystem args
- Pass extraPythonPackages as Python list literal instead of colon-split string
* fix: walk propagatedBuildInputs for plugin PYTHONPATH and collision check
Uses python312.pkgs.requiredPythonModules to resolve the full transitive
closure of extraPythonPackages. Without this, a plugin with third-party
deps (e.g. requests) would fail at runtime if those deps weren't already
in the sealed uv2nix venv. The collision check now also scans the full
closure, catching transitive conflicts.
* cleanup: fold plugins into subdir loop, use find for symlink cleanup, inline lib.getName
- Add 'plugins' to the existing cron/sessions/logs/memories subdir loop
instead of a separate mkdir/chown/chmod block
- Replace fragile for-glob with find -delete for stale symlink cleanup
- Inline lib.getName at both call sites, remove pluginName wrapper
Handle queued-title ValueError cleanup during session init, harden Discord message source building for test stubs, and fix the Dockerfile contract test syntax error. Also refresh the TUI lockfile and Nix build flags so nix ubuntu-latest no longer fails on npm lock/peer resolution drift.
* fix(nix): use --rebuild in fix-lockfiles to bypass cached FOD store paths
fix-lockfiles checked npm lockfile hashes by running
`nix build .#<attr>.npmDeps`, but fetchNpmDeps is a fixed-output
derivation — if the old store path exists locally, Nix returns it from
cache without re-fetching. This caused the script to report "ok" even
when hashes were stale, while CI (with no cache) failed with a hash
mismatch.
Adding --rebuild forces Nix to re-derive and verify the output hash
against the declared one, catching staleness regardless of local cache
state. Also updates the tui and web npm deps hashes that were stale.
* fix(nix): regenerate ui-tui lockfile to add missing @emnapi entries
npm ci was failing because @emnapi/core and @emnapi/runtime were
missing from ui-tui/package-lock.json despite being required as peer
deps by @napi-rs/wasm-runtime (via @rolldown/binding-wasm32-wasi).
Running npm install --package-lock-only adds the missing entries.
The npmDepsHash reverts to its previous value since fetchNpmDeps was
already fetching these packages as transitive dependencies.
The web dashboard (Vite/React frontend) is now built as a separate Nix
derivation and baked into the Hermes package. The build output is
installed to a standard location and exposed via the `HERMES_WEB_DIST`
environment variable, allowing the dashboard command to use pre-built
assets when available (e.g., in packaged releases) instead of rebuilding
on every invocation.
* Add setuptools build dep for legacy alibabacloud packages and updated
stale npm-deps hash
* Add HERMES_NODE env var to pin Node.js version
The TUI requires Node.js 20+ for regex `/v` flag support (used by
string-width). Instead of relying on PATH lookup, explicitly set
HERMES_NODE to the bundled Node 22 in the Nix wrapper, and add a
fallback check in the Python code to use HERMES_NODE if available.
Also upgrade container provisioning to Node 22 via NodeSource (Ubuntu
24.04 ships Node 18 which is EOL) and add a Nix check to verify the
wrapper and Node version at build time.
* feat(nix): container-aware CLI — auto-route all subcommands into managed container
When container.enable = true, the host `hermes` CLI transparently execs
every subcommand into the managed Docker/Podman container. A symlink
bridge (~/.hermes -> /var/lib/hermes/.hermes) unifies state between host
and container so sessions, config, and memories are shared.
CLI changes:
- Global routing before subcommand dispatch (all commands forwarded)
- docker exec with -u exec_user, env passthrough (TERM, COLORTERM,
LANG, LC_ALL), TTY-aware flags
- Retry with spinner on failure (TTY: 5s, non-TTY: 10s silent)
- Hard fail instead of silent fallback
- HERMES_DEV=1 env var bypasses routing for development
- No routing messages (invisible to user)
NixOS module changes:
- container.hostUsers option: lists users who get ~/.hermes symlink
and automatic hermes group membership
- Activation script creates symlink bridge (with backup of existing
~/.hermes dirs), writes exec_user to .container-mode
- Cleanup on disable: removes symlinks + .container-mode + stops service
- Warning when hostUsers set without addToSystemPackages
* fix: address review — reuse sudo var, add chown -h on symlink update
- hermes_cli/main.py: reuse the existing `sudo` variable instead of
redundant `shutil.which("sudo")` call that could return None
- nix/nixosModules.nix: add missing `chown -h` when updating an
existing symlink target so ownership stays consistent with the
fresh-create and backup-replace branches
* fix: address remaining review items from cursor bugbot
- hermes_cli/main.py: move container routing BEFORE parse_args() so
--help, unrecognised flags, and all subcommands are forwarded
transparently into the container instead of being intercepted by
argparse on the host (high severity)
- nix/nixosModules.nix: resolve home dirs via
config.users.users.${user}.home instead of hardcoding /home/${user},
supporting users with custom home directories (medium severity)
- nix/nixosModules.nix: gate hostUsers group membership on
container.enable so setting hostUsers without container mode doesn't
silently add users to the hermes group (low severity)
* fix: simplify container routing — execvp, no retries, let it crash
- Replace subprocess.run retry loop with os.execvp (no idle parent process)
- Extract _probe_container helper for sudo detection with 15s timeout
- Narrow exception handling: FileNotFoundError only in get_container_exec_info,
catch TimeoutExpired specifically, remove silent except Exception: pass
- Collapse needs_sudo + sudo into single sudo_path variable
- Simplify NixOS symlink creation from 4 branches to 2
- Gate NixOS sudoers hint with "On NixOS:" prefix
- Full test rewrite: 18 tests covering execvp, sudo probe, timeout, permissions

* feat(nix): shared-state permission model for interactive CLI users
Enable interactive CLI users in the hermes group to share full
read-write state (sessions, memories, logs, cron) with the gateway
service via a setgid + group-writable permission model.
Changes:
nix/nixosModules.nix:
- Directories use setgid 2770 (was 0750) so new files inherit the
hermes group. home/ stays 0750 (no interactive write needed).
- Activation script creates HERMES_HOME subdirs (cron, sessions, logs,
memories) — previously Python created them but managed mode now skips
mkdir.
- Activation migrates existing runtime files to group-writable (chmod
g+rw). Nix-managed files (config.yaml, .env, .managed) stay 0640/0644.
- Gateway systemd unit gets UMask=0007 so files it creates are 0660.
hermes_cli/config.py:
- ensure_hermes_home() splits into managed/unmanaged paths. Managed mode
verifies dirs exist (raises RuntimeError if not) instead of creating
them. Scoped umask(0o007) ensures SOUL.md is created as 0660.
hermes_logging.py:
- _ManagedRotatingFileHandler subclass applies chmod 0660 after log
rotation in managed mode. RotatingFileHandler.doRollover() creates new
files via open() which uses the process umask (0022 → 0644), not the
scoped umask from ensure_hermes_home().
Verified with a 13-subtest NixOS VM integration test covering setgid,
interactive writes, file ownership, migration, and gateway coexistence.
Refs: #6044
* Fix managed log file mode on initial open
Co-authored-by: Siddharth Balyan <alt-glitch@users.noreply.github.com>
* refactor: simplify managed file handler and merge activation loops
- Cache is_managed() result in handler __init__ instead of lazy-importing
on every _open()/_chmod_if_managed() call. Avoids repeated stat+env
checks on log rotation.
- Merge two for-loops over the same subdir list in activation script
into a single loop (mkdir + chown + chmod + find in one pass).

- build tui.nix, copy to $out/ui-tui/ (same layout as dev)
- set HERMES_TUI_DIR, HERMES_PYTHON in wrapper
- add passthru.devShellHook with stamp-checked venv setup
- expose tui as separate package output
* fix(nix): export HERMES_HOME system-wide when addToSystemPackages is true
The `addToSystemPackages` option's documentation (and the `:::tip` block in
`website/docs/getting-started/nix-setup.md`) promises that enabling it both
puts the `hermes` CLI on PATH and sets `HERMES_HOME` system-wide so interactive
shells share state with the gateway service. The module only did the former,
so running `hermes` in a user shell silently created a separate `~/.hermes/`
directory instead of the managed `${stateDir}/.hermes`.
Implement the documented behavior by also setting
`environment.variables.HERMES_HOME = "${cfg.stateDir}/.hermes"` in the same
mkIf block, and update the option description to match.
Fixes#6044
* fix(nix): preserve group-readable permissions in managed mode
The NixOS module sets HERMES_HOME directories to 0750 and files to 0640
so interactive users in the hermes group can share state with the gateway
service. Two issues prevented this from working:
1. hermes_cli/config.py: _secure_dir() unconditionally chmod'd HERMES_HOME
to 0700 on every startup, overwriting the NixOS module's 0750. Similarly,
_secure_file() forced 0600 on config files. Both now skip in managed mode
(detected via .managed marker or HERMES_MANAGED env var).
2. nix/nixosModules.nix: the .env file was created with 0600 (owner-only),
while config.yaml was already 0640 (group-readable). Changed to 0640 for
consistency — users granted hermes group membership should be able to read
the managed .env.
Verified with a NixOS VM integration test: a normal user in the hermes group
can now run `hermes version` and `hermes config` against the managed
HERMES_HOME without PermissionError.

Activation script, tmpfiles, and container entrypoint now agree on
0750 for all directories. Tighten config.yaml and workspace documents
from 0644 to 0640 (group-readable, no world access). Add explicit
chmod for .managed marker and container $TARGET_HOME to eliminate
umask dependence. Secrets (auth.json, .env) remain 0600.
* refactor: suffix runtimeDeps PATH so apt-installed tools take priority
Changes makeWrapper from --prefix to --suffix. In container mode,
tools installed via apt in /usr/bin now win over read-only nix store
copies. Nix store versions become dead-letter fallbacks. Native NixOS
mode unaffected — tools in /run/current-system/sw/bin already precede
the suffix.
* feat(container): first-boot apt provisioning for agent tools
Installs nodejs, npm, curl via apt and uv via curl on first container
boot. Uses sentinel file so subsequent boots skip. Container recreation
triggers fresh install. Combined with --suffix PATH change, agents get
mutable tools that support npm i -g and uv without hitting read-only
nix store paths.
* docs: update nixosModules header for tool provisioning
* feat(container): consolidate first-boot provisioning + Python 3.11 venv
Merge sudo and tool apt installs into a single apt-get update call.
Move uv install outside the sentinel so transient failures retry on
next boot. Bootstrap a Python 3.11 venv via uv (--seed for pip) and
prepend ~/.venv/bin to PATH so agents get writable python/pip/node
out of the box.

* feat: nix flake, uv2nix build, dev shell and home manager
* fixed nix run, updated docs for setup
* feat(nix): NixOS module with persistent container mode, managed guards, checks
- Replace homeModules.nix with nixosModules.nix (two deployment modes)
- Mode A (native): hardened systemd service with ProtectSystem=strict
- Mode B (container): persistent Ubuntu container with /nix/store bind-mount,
identity-hash-based recreation, GC root protection, symlink-based updates
- Add HERMES_MANAGED guards blocking CLI config mutation (config set, setup,
gateway install/uninstall) when running under NixOS module
- Add nix/checks.nix with build-time verification (binary, CLI, managed guard)
- Remove container.nix (no Nix-built OCI image; pulls ubuntu:24.04 at runtime)
- Simplify packages.nix (drop fetchFromGitHub submodules, PYTHONPATH wrappers)
- Rewrite docs/nixos-setup.md with full options reference, container
architecture, secrets management, and troubleshooting guide
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Update config.py
* feat(nix): add CI workflow and enhanced build checks
- GitHub Actions workflow for nix flake check + build on linux/macOS
- Entry point sync check to catch pyproject.toml drift
- Expanded managed-guard check to cover config edit
- Wrap hermes-acp binary in Nix package
- Fix Path type mismatch in is_managed()
* Update MCP server package name; bundled skills support
* fix reading .env. instead have container user a common mounted .env file
* feat(nix): container entrypoint with privilege drop and sudo provisioning
Container was running as non-root via --user, which broke apt/pip installs
and caused crashes when $HOME didn't exist. Replace --user with a Nix-built
entrypoint script that provisions the hermes user, sudo (NOPASSWD), and
/home/hermes inside the container on first boot, then drops privileges via
setpriv. Writable layer persists so setup only runs once.
Also expands MCP server options to support HTTP transport and sampling.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix group and user creation in container mode
* feat(nix): persistent /home/hermes and MESSAGING_CWD in container mode
Container mode now bind-mounts ${stateDir}/home to /home/hermes so the
agent's home directory survives container recreation. Previously it lived
in the writable layer and was lost on image/volume/options changes.
Also passes MESSAGING_CWD to the container so the agent finds its
workspace and documents, matching native mode behavior.
Other changes:
- Extract containerDataDir/containerHomeDir bindings (no more magic strings)
- Fix entrypoint chown to run unconditionally (volume mounts always exist)
- Add schema field to container identity hash for auto-recreation
- Add idempotency test (Scenario G) to config-roundtrip check
* docs: add Nix & NixOS setup guide to docs site
Add comprehensive Nix documentation to the Docusaurus site at
website/docs/getting-started/nix-setup.md, covering nix run/profile
install, NixOS module (native + container modes), declarative settings,
secrets management, MCP servers, managed mode, container architecture,
dev shell, flake checks, and full options reference.
- Register nix-setup in sidebar after installation page
- Add Nix callout tip to installation.md linking to new guide
- Add canonical version pointer in docs/nixos-setup.md
* docs: remove docs/nixos-setup.md, consolidate into website docs
Backfill missing details (restart/restartSec in full example,
gateway.pid, 0750 permissions, docker inspect commands) into
the canonical website/docs/getting-started/nix-setup.md and
delete the old standalone file.
* fix(nix): add compression.protect_last_n and target_ratio to config-keys.json
New keys were added to DEFAULT_CONFIG on main, causing the
config-drift check to fail in CI.
* fix(nix): skip checks on aarch64-darwin (onnxruntime wheel missing)
The full Python venv includes onnxruntime (via faster-whisper/STT)
which lacks a compatible uv2nix wheel on aarch64-darwin. Gate all
checks behind stdenv.hostPlatform.isLinux. The package and devShell
still evaluate on macOS.
* fix(nix): skip flake check and build on macOS CI
onnxruntime (transitive dep via faster-whisper) lacks a compatible
uv2nix wheel on aarch64-darwin. Run full checks and build on Linux
only; macOS CI verifies the flake evaluates without building.
* fix(nix): preserve container writable layer across nixos-rebuild
The container identity hash included the entrypoint's Nix store path,
which changes on every nixpkgs update (due to runtimeShell/stdenv
input-addressing). This caused false-positive identity mismatches,
triggering container recreation and losing the persistent writable layer.
- Use stable symlink (current-entrypoint) like current-package already does
- Remove entrypoint from identity hash (only image/volumes/options matter)
- Add GC root for entrypoint so nix-collect-garbage doesn't break it
- Remove global HERMES_HOME env var from addToSystemPackages (conflicted
with interactive CLI use, service already sets its own)
