What problem does it solve? Work handed off from a Kanban implementation lane needs independent verification before completion, and rubber-stamping handoff summaries lets defects slip through. This Skill gives a reviewer agent a structured procedure to verify deliverables against acceptance criteria and record an evidence-backed verdict. ## Core Features & Use Cases - Independent verdict routing: Approve with kanban_complete, request changes with kanban_request_changes, or escalate with kanban_block, each with concrete evidence recorded in the transition. - Round-based review lenses: Rotate between artifact, execution, and contract lenses across review rounds so repeated reviews catch different defect classes instead of re-finding the same issues. - Role separation enforcement: The reviewer never edits the implementation, preserving ownership boundaries and keeping re-review independent. - Use Case: An implementer submits a review_requested handoff claiming a bug fix with passing tests. The reviewer reads the task via kanban_show, checks out the diff, runs the focused tests, finds an unhandled edge case, and returns the task with actionable findings. ## Quick Start Ask the agent to review the current Kanban review-lane task by reading the handoff with kanban_show, verifying the deliverable against the acceptance criteria, and submitting exactly one verdict.
