What problem does it solve? Tickets are implemented one per session, and each session only sees its own ticket, so defects spanning multiple tickets go unnoticed. This Skill runs a transversal consistency review over the accumulated work of several tickets, catching what no isolated session could see. ## Core Features & Use Cases - Interval-based review: Delimits each review cycle by the checkpoint commits already in git history (refactor: checkpoint / docs(checkpoint):), so markers travel with the clone without tags or hooks. - Reviewer agent dispatch: Launches the checkpoint-reviewer agent with the commit interval, ticket locations, and the batch of closed tickets, returning a four-list report without modifying code. - Quarantine routing: Routes real defects into a quarantine container (files under .scratch/<feature>/checkpoint/ or labeled tracker comments) with an explicit human promotion criterion, keeping the feature queue from growing. - Use Case: After every five tickets closed in an autonomous /ticket:run queue, invoke this Skill to review the accumulated commits, apply small fixes in a single checkpoint commit, and file cross-ticket findings for human triage. ## Quick Start Ask the AI to run a checkpoint review over the tickets closed since the last checkpoint commit and route any findings into quarantine.
