What problem does it solve? Deleting a shared runtime checkout that multiple task silos still reference can break open PRs, running servers, and unpushed work. This Skill enforces a safe deletion workflow that checks references, git state, and active processes before removing or archiving runtime directories. ## Core Features & Use Cases - Reference Verification: Scans runtime registry/status, task silo goals, open PRs, handoffs, running processes, and ports before any deletion. - Archive-First Policy: Marks runtimes as status: archived with reason and date when deletion is uncertain, instead of removing them outright. - Guarded Destructive Actions: Only deletes directories after explicit user approval, blocking removal when dirty state, ahead commits, or active references exist. - Use Case: When cleaning up an old shared-runtime/<project-id>/<runtime-name>/ checkout, the Skill checks linked tasks and git status, reports preservation risks, and archives or deletes only after confirmation. ## Quick Start Ask the agent to review and safely delete or archive the shared runtime named api-server for project demo, checking all references first.
