Specs, sealed — a Claude Code plugin: implement/review agent chain, an evidence ledger with drift detection, and hook-enforced gates.
Agent
Migration fact-finder. Spawn only in projects with a migration config (.specseal/parity.md) to establish what the original code actually does — facts with coordinates, no verdicts. Called by smith during implementation and by the review orchestrator during parity review.
Agent
Implementation agent. Spawn for feature work, ticket implementation, refactors, and incorporating review feedback. Follows the implement skill (SDD procedure, three-axis document layout); hands finished work to the review chain.
Agent
Review agent. Spawn to review a PR, diff, or branch — spec compliance first, then quality. Reads earlier review rounds and inherits their verdicts; returns a report for the orchestrator to verify and post.
