What problem does it solve? After a plan runs, workspaces accumulate leftover planning documents, scaffolding files, and temporary artifacts that clutter the repository and create tech debt. This Skill identifies and removes those leftovers safely, with explicit confirmation before any deletion. ## Core Features & Use Cases - Artifact Identification: Scans for planning docs (PLAN.md, implementation_plan.md, *-plan.md), execution scaffolding, and incidental tool directories, verifying each candidate is truly a planning leftover. - Confirmed Removal: Presents the full artifact list and removes only user-approved files, using git rm for tracked files and rm for untracked ones. - Verification and Commit: Confirms each deletion, commits tracked removals with a chore message, and ends with a required terminal declaration. - Use Case: After finishing a multi-phase implementation plan, run the cleanup to delete PLAN.md and temporary stub files, then commit the cleaned tree in one pass. ## Quick Start Ask the agent to clean up the planning artifacts left in the workspace after the plan finished executing.
