What problem does it solve? Plugins built by distilling content from upstream sources pin each skill to a source commit, but upstream repos keep moving. This Skill audits every skill's source / source_version frontmatter against the current upstream HEAD and tells you which skills are still accurate, which only need a mechanical pin bump, and which need human re-distillation. ## Core Features & Use Cases - Drift classification: Labels every skill CLEAN, PIN-ONLY, STALE, UNPINNED, or DEGRADED by diffing pinned commits against upstream HEAD restricted to each skill's source paths. - Read-only audit: Never edits skills, bumps pins, commits, or fetches; it emits a markdown re-distillation plan a human acts on. - Actionable report: Writes a timestamped markdown plan with per-skill diff summaries, re-check pointers, and ordered next steps (author pins, re-distill STALE, bulk-bump PIN-ONLY). - Use Case: Before a plugin release, run the audit to discover that amw-shadcn-ui is STALE because components/ui/button.tsx changed upstream, while 40 other skills only need a pin bump. ## Quick Start Ask the agent to audit skill drift in this plugin and check all skill pins against their upstream sources, then write the re-distillation plan to the reports directory.
