What problem does it solve? Active plan folders accumulate stale, completed, or obsolete plan files over time, making it hard to know which plans reflect real work. This Skill reconciles plan artifacts against the actual codebase so the active plan inventory stays accurate. ## Core Features & Use Cases - Plan Inventory Validation: Runs a deterministic Node.js validator that scans process/general-plans/ and process/features/ for naming, freshness, and structure drift. - Codebase Cross-Checking: Verifies each plan's claimed files and features with glob and grep checks, then classifies plans as Completed, Partially Done, Obsolete, Stale, Active, or Reference. - Stale Artifact Cleanup: Detects co-located REPORT/REF/SPEC artifacts tied to finished plans and moves whole task folders to completed/ via git mv. - Use Case: After a burst of feature work where the update process was skipped, run this Skill to archive finished plans, flag stale ones, and produce a summary table of actions taken. ## Quick Start Ask the AI to audit the active plans in process/general-plans and process/features, classify each one against the codebase, and archive anything completed or obsolete.
