List tasks (optional status filter).

Show the one task that may start now: the queue head, planned, with dependencies and the phase gate met.

Claim a planned task (-> in_progress, sets owner and started). Refused unless every earlier task is done/cancelled (order and phase gate) and its dependencies are done.

Advance a task's status and record evidence (transitions are enforced). Send verification_result and review_result in SEPARATE calls: the caller identity (by) is the verifier; a review must come from the reviewer identity of the task's profile (see task_show), a different one, after that profile's delay since the stored verification, and must list the commands it checked in checks=[...]; closing as done needs a fresh review_result in the same call, unless the task's profile sets require_review = false. A task with open subtasks cannot go to in_review, done or cancelled.

Render the Markdown view from tasks.json; check=true fails on drift instead of writing.

Validate tasks.json: schema, status transitions and evidence gates.

One task with its effective closing policy (profile, whether a review is required and by whom, review delay, quality gates) and its subtasks. Read it before verifying or reviewing to know what that task needs.

Set or clear the review/verification profile of a draft/planned task (profiles are defined in taskgate.toml, e.g. a docs profile without review). Not allowed once the task has started. Planners only; pass name or clear=true.

Add a draft/planned task or, with parent, a subtask (id . assigned when id is omitted; one level, phase and default profile come from the parent; the parent must be in_progress before a subtask can start, and cannot close while subtasks are open). profile picks a review/verification profile from taskgate.toml. Duplicate ids and closed phases are rejected. Only identities listed in 'planners' may add tasks; pass by explicitly.

Reset the execution order to phase, then id; discards any order set with task_move.

Change the execution order: place a draft/planned task directly before or after another. Never in front of a task that is in flight or done, and phases stay ascending. Planners only; pass exactly one of before/after.

Change the dependencies of a draft/planned task: set (replace; [] clears), add and/or remove ids. Each dependency must exist and be placed before the task (use task_move first). Planners only.

Run quality gates and return a compact JSON report. Gate names come from [quality] in taskgate.toml; the built-in gate 'tasks' validates the registry and checks the Markdown view. Without 'checks' every gate runs; with task= only the gates of that task's profile run (a docs task can skip the build and test gates).
