Implements review-comment suggestions across one or more PRs. Multi-PR mode (default when $ARGUMENTS holds PR URLs; empty $ARGUMENTS auto-detects the active PR) resolves a worktree per PR, fetches every actionable comment from human teammates AND AI review bots (claude[bot], coderabbitai[bot], …), validates each through /critical + /confidence, builds a structured suggestion-pack, and dispatches a worker subagent that applies each approved change as its own commit, pushes to the existing branch, and resolves the addressed thread — so every handled comment ends resolved and the PR is left clean. Free-text mode applies a single pasted suggestion in place. --watch re-applies on one PR until the reviewers go quiet (max 5 iterations); --resolve-all also replies to and resolves every non-fix thread it can honestly close. Triggers on "implement suggestion", "apply review comments", "/implement-suggestion".
