What problem does it solve? After a change's PR merges, its delta specs sit unarchived and the project's living specs drift out of sync with shipped behavior. This Skill closes that loop by merging delta requirements into the living specs and moving the change directory into the archive tree. ## Core Features & Use Cases - Delta spec folding: Reads ADDED, MODIFIED, and REMOVED requirement sections from a change's delta specs and merges them into behavior-level living specs under openspec/specs/. - Knowledge distillation: Crystallizes durable terms into CONTEXT.md and offers ADRs for hard-to-reverse decisions with real trade-offs. - Git-history-preserving archive: Moves the change directory into openspec/changes/archive/ with a merge-date prefix using git mv, then commits everything together. - Use Case: After PR #42 for the checkout-tax change merges, run the archive command to fold its requirements into the living checkout-tax spec, record a gotcha in CONTEXT.md, and archive the change directory as 2026-05-01-checkout-tax. ## Quick Start Invoke /pavilio-archive-plan with the project and change-id to archive a merged change and fold its delta specs into the living specs.
