Archive Artifacts

Use this skill when a maintainer needs an explicit archival step that preserves durable history without broad cleanup side effects.

Responsibilities

1. Discover archive candidates across proposals, features, subfeatures, and closed slices.
2. Keep candidate reporting read-only by default.
3. Archive one closed execution slice explicitly through the execution owner helper.
4. Summarize closed slices for one feature or subfeature into system-design.md before archiving them.
