name	metis-review-task
description	Dispatch the metis-task-reviewer subagent to judge a diff against the task description and plan. Returns a verdict with per-criterion evidence.

$metis-review-task

Dispatch the metis-task-reviewer subagent to review one implementation against the description and plan it was meant to satisfy.

Arguments

• Trailing prompt — optional. Augments the dispatch prompt per the command-prompts convention (e.g., narrowing the diff range, flagging a specific concern).

Context expected

The parent collects what the reviewer needs from conversation context before dispatching:

• The description the work was implemented against — from this session's chat history, or rehydrated from .metis/CURRENT.md via $metis-session-start.
• The plan, if one was produced — same sources.
• The implementer's scope report — produced by $metis-implement-task at the close of implementation; in chat history or in .metis/CURRENT.md.

If any of these are missing, ask the user before dispatching. Reviewing an unstated brief is the silent-drift mirror of implementing one.

Preflight

Run this skill's references/review-task-preflight.sh. It exits non-zero if the working directory isn't a git repo. On success it reports two fields:

• BASELINE — the branch the implementation diverges from. First existing of main, master, origin/main, origin/master; empty if none exist (the subagent then reviews only uncommitted changes).
• DIFF_PRESENT — yes if there are uncommitted changes or commits ahead of BASELINE; no otherwise.

If DIFF_PRESENT=no, surface an "empty diff" finding without dispatching — no implementation work to judge.

Subagent dispatch

Dispatch the metis-task-reviewer subagent with a single structured prompt containing:

• The description.
• The plan, if one was produced.
• The implementer's scope report.
• The BASELINE from the preflight (the branch the subagent should diff against).
• Any trailing prompt the user passed to this skill, verbatim.

The subagent reads the git diff itself; the parent does not need to embed it.

Write scope

This command writes nothing.

Invocation prompt

Trailing prompt: forwarded verbatim to the subagent.

Return

Relay the subagent's return:

• Verdict — approve, approve-with-nits, or reject-with-reasons.
• Per-criterion results — pass/fail with evidence, for each criterion the description and plan implied.
• Scope reduction findings — whether the implementer's scope report honestly describes what's missing, and any reductions the implementer didn't surface.
• Code-quality notes — separate from spec compliance.
• Next step:
  • approve / approve-with-nits — user commits/merges.
  • reject-with-reasons — back to $metis-implement-task with the reviewer's findings as the trailing prompt.

If the subagent returns an "empty diff" finding instead of a review, pass it through as-is.
