review-pr

Read-only audit of an open pull request. Drives the PR's diff through the full agent pipeline (slice → fan-out → merge → verify) and emits findings in the structured format. Never edits, never pushes, never resolves review threads, never gh pr edit.

Two output modes:

• Terminal report (default) — prints findings grouped by severity in the current terminal.
• Comment mode (--comment flag or user explicitly asks "post these as PR comments") — posts findings via gh pr comment (top-level) or the inline-comment API (file:line anchors).

This is the read-only twin of /drive-pr. Same audit; no writes.

Phase 0 — Resolve the PR

Accept PR resolution from any of:

• explicit #N, <url>, or <owner/repo>#N argument
• current branch via gh pr view --json number,headRefName,baseRefName,url,state
• prompt the user if neither

Validate the PR exists (gh pr view <ref>). Closed and merged PRs are still auditable.
