Description

otari hook now evaluates a repo's .otari-gates.yml policy locally, in process, instead of going through otari serve's Hook Server for every check. Running the CLI's own evaluator directly means gate enforcement no longer needs a running gateway or a credential for the common case: registering the hook (otari hook setup) and checking a policy now both work standalone.

POST /api/v1/hooks/check stays available for anyone who wants a shared or hosted gateway to be the one deciding instead: passing --url/--api-key (or OTARI_URL/OTARI_API_KEY) opts back into that HTTP-backed mode, unchanged from before. Both paths now run through the exact same pure evaluator (agent_runtime.domain.check.run_policy_check), so local and server checks can never drift apart.

otari hook setup no longer resolves or prompts for a credential by default either; it only embeds one when --api-key is given explicitly.

How to test it locally

  • Run uv sync uv run otari hook setup in a repo with a .otari-gates.yml, with no otari serve running and no credential configured. Trigger a forbidden edit or command and confirm it's refused, with no network call made.
  • Automated coverage: tests/unit/test_hook_cli.py, tests/unit/agent_runtime/test_check.py (new), tests/integration/test_hooks_route.py (unchanged HTTP contract, 58 tests), plus make lint, uv run mypy, make openapi-check, make postman-check.

Summary

otari hook now evaluates .otari-gates.yml locally by default. This workflow does not require a running server or credentials.

When --url or --api-key is set, the command uses the Hook Server endpoint. If the API key is not set, it can use the configured master key. hook setup embeds a key only when you provide --api-key; it does not resolve or prompt for credentials by default.

The CLI and Hook Server now use the shared run_policy_check evaluator. The PR also updates documentation and API descriptions, and adds or revises tests for local checks, remote checks, and setup.

Technical notes

  • Local evaluation errors fail open and do not block the operation.
  • The Hook Server returns HTTP 422 when run_policy_check raises PolicyCheckError.

Walkthrough

The PR adds a shared policy evaluator, uses it for local otari hook execution by default, preserves opt-in HTTP evaluation, removes automatic credential resolution during setup, and updates tests and documentation.

Changes

Agent gates

Layer / File(s) Summary
Shared policy evaluation
src/gateway/agent_runtime/domain/check.py, src/gateway/api/routes/hooks.py, tests/unit/agent_runtime/test_check.py, tests/integration/test_hooks_route.py
Adds run_policy_check, validation and work budgets, gate dispatch, aggregate results, and PolicyCheckError. The Hook Server delegates to this evaluator. Tests cover gate outcomes, omitted evidence, malformed policies, and oversized inputs.
Local and remote hook execution
src/gateway/cli.py, tests/unit/test_hook_cli.py, tests/unit/test_hook_setup_cli.py
Makes local evaluation the default when no URL or API key is provided. URL or API-key options select HTTP evaluation. Setup no longer resolves or prompts for credentials. CLI tests cover both paths and fail-open behavior.
Evaluation and registration documentation
docs/agent-gates.md, docs/index.md, docs/public/otari.postman_collection.json, src/gateway/AGENTS.md, web/src/client/schema.ts
Documents the shared evaluator, local default behavior, optional Hook Server usage, credential handling, and updated hook registration commands.

Clarify the -c guidance sentence.

This sentence packs several conditions together, and the boundaries between them are hard to follow on a first read: "Pass -c whenever your master_key lives in config.yml rather than in .env or the environment and you have opted into this mode without --api-key, or the hook finds no credential."

Consider splitting it into two clear conditions instead. For example: "Pass -c when you have opted into this mode without --api-key and your master_key lives in config.yml rather than in .env or the environment. Skip it and the hook finds no credential." Small tweak, easier read for anyone hitting this section under time pressure.

Consider adding a command-evidence case to this new suite.

The suite covers changed_path, judge, and check_passed well. The command branch of run_policy_check (lines 193-248 of check.py: the scope handling, the shared segment_cache/phrase_cache, and the command work budget) is the most intricate logic that moved out of routes/hooks.py, and nothing here exercises it. One command_match test with command_scope="session" versus "call" would lock in the scope contract cheaply.

Not a blocker, and the integration tests may already cover the route side; this is about keeping the pure evaluator's own suite complete now that it owns the budgets.

otari hook now evaluates .otari-gates.yml in process by default, needing
no running otari serve and no credential: the parse-and-evaluate logic
that used to live inline in routes/hooks.py is now a shared, pure
function (agent_runtime.domain.check.run_policy_check) that both the
Hook Server route and the CLI call. POST /api/v1/hooks/check stays as
an opt-in path via --url/--api-key (or OTARI_URL/OTARI_API_KEY), for a
caller that wants a shared or hosted gateway to decide instead.

otari hook setup no longer resolves or prompts for a credential by
default; it only embeds one when --api-key is given explicitly.

Regenerates docs/public/openapi.json and the Postman collection for the
check_policy route's updated docstring.
