ef41d3bd45 feat(nix): declarative plugin installation for NixOS module (#15953)
* 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

6fb69229ca fix(nix): fix build failures, TUI Node.js crash, and upgrade container to Node 22 (#12159)
* 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.

b6461903ff feat: nix flake — uv2nix build, NixOS module, persistent container mode (#20)
* 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.

* 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)
