What problem does it solve? Repositories accumulate clutter over time: stale AWS CloudFormation deployment stacks, merged git branches, abandoned worktrees, test logs, and build output. This Skill finds all five categories of leftover artifacts, presents them in one table, and removes only what the operator approves in a single pass. ## Core Features & Use Cases - Stale deployment detection: Queries AWS CloudFormation stacks across ci and prod profiles, compares them against last-known-good SSM parameters, and destroys stale sets via GitHub workflow runs. - Branch and worktree cleanup: Identifies merged or content-on-main branches (local and remote), protects branches with open PRs or unique commits, and removes worktrees of merged branches while keeping ones with uncommitted work. - Artifact and build output removal: Deletes logs, Playwright reports, test results, target/, cdk.out/, node_modules/, and the bundled JS file, then runs npm ci and npm run bundle to restore a working state. - Use Case: After a sprint of feature work, say "clean up" and the Skill gathers every stale deployment, merged branch, orphaned worktree, and build artifact, shows them in one table, and removes only the categories you approve before returning the checkout to an up-to-date main branch. ## Quick Start Tell the assistant to clean up the repository and approve the categories of stale deployments, branches, worktrees, logs, and build output you want removed.
