oclaw/runtime/hooks

Python hooks runtime and bundled hook packages (parity target: OpenClaw src/hooks).

What you get

• In-process hook bus: register on type or type:action, sync/async handlers, isolated failures.
• Directory discovery: HOOK.md + one handler file per hook directory (first match in priority order, see workspace._handler_candidates).
• Config gating: hooks.internal.enabled and hooks.internal.entries.<hookKey>.enabled.
• Source precedence: bundled / managed / workspace / plugin collision resolution (policy).
• Eligibility: OS / bins / env / config paths; optional remote context from message metadata (eligibility_from_metadata + config.should_include_hook).

Handler entry priority

First existing file under the hook directory wins:

handler.py → index.py → handler.ts → index.ts → handler.mts → index.mts → handler.cts → index.cts → handler.mjs → index.mjs → handler.cjs → index.cjs → handler.sh → index.sh → handler.bash → index.bash

Hook layout

Put hooks in any of:

• Bundled: shipped with runtime (runtime_hooks_bundled_root())
• Managed: ~/.oclaw/hooks/<hookName>/
• Workspace: <workspace>/hooks/<hookName>/
• Plugin: .openclaw/extensions/<id>/.codex-plugin/plugin.json → hooks paths
• Extra dirs: hooks.internal.load.extraDirs plus skill-side .../hooks dirs merged at runtime init

Each hook directory needs HOOK.md (YAML frontmatter with metadata.oclaw.events) plus one handler file as above.

Remote eligibility on inbound messages

Callers (e.g. gateway) may attach JSON metadata:

{
  "hookEligibility": {
    "remote": {
      "platforms": ["linux"],
      "binsPresent": ["git", "node"],
      "note": "remote agent capabilities"
    }
  }
}

Parsed by hook_eligibility_from_message_metadata and passed into initialize_hooks_runtime(..., eligibility=...). Note: hook runtime initializes once per process; the first successful init wins (see hooks_runtime.initialize_hooks_runtime).

Minimal self-test

From the repository root (see tests/conftest.py for sys.path layout):

python runtime/hooks/_selftest.py

or run hook discovery / parity tests:

pytest tests/test_oclaw_hooks_bundled_parity.py tests/test_oclaw_hooks_runtime.py -q

Operations CLI (from parent of this repo on sys.path, see tests/conftest.py)

python -m oclaw.runtime.operations hooks list
python -m oclaw.runtime.operations hooks list --eligible --verbose
python -m oclaw.runtime.operations hooks check --json
python -m oclaw.runtime.operations hooks info session-memory --workspace /path/to/workspace
python -m oclaw.runtime.operations hooks enable session-memory --workspace /path/to/workspace
python -m oclaw.runtime.operations hooks disable command-logger --workspace /path/to/workspace
python -m oclaw.runtime.operations hooks install ./path-or-npm-spec   # deprecated, exit 2 + hints
python -m oclaw.runtime.operations hooks update --dry-run             # deprecated, exit 2 + hints

Uses the same merged config as the agent runtime (including skill hooks/ extra dirs via merge_skill_hook_extra_dirs_into_config).

Enable matches OpenClaw semantics: the hook must satisfy requirements (bins/os/env/config) if its config entry were turned on; plugin hooks cannot be toggled from this CLI. Writes go to OCLAW_CONFIG_PATH (optional, relative paths resolved under PROJECT_ROOT) or oclaw/oclaw.json by default.
