What problem does it solve? Active plan folders accumulate stale, completed, or obsolete planning artifacts over time, making it hard to know which plans reflect real work. This Skill reconciles plan files against the actual codebase so your planning directories stay truthful. ## Core Features & Use Cases - Plan Inventory Validation: Runs a deterministic Node.js validator that counts active and completed plans, flags naming drift, duplicate basenames, and missing verification sections. - Codebase Cross-Referencing: Verifies each plan against the real code with file existence checks and targeted grep searches, then classifies plans as Completed, Partially Done, Obsolete, Stale, Active, or Reference. - Stale Artifact Detection: Finds co-located report, reference, and spec files tied to completed or obsolete plans and recommends archiving or relocation into task folders. - Use Case: After a burst of feature work where cleanup was skipped, run this Skill to archive finished task folders with git mv, flag stale plans for user decision, and produce a summary table of actions taken. ## Quick Start Ask the assistant to audit the active plans in process/general-plans/active and process/features for staleness and archive anything completed.
