What problem does it solve? Teams adopting the Agentic SDLC workflow need a safe way to confirm that all phase skills, hooks, and execution capabilities actually work as designed before trusting them on a real repository. This Skill acts as an external test harness that audits the SDLC system without joining the workflow itself. ## Core Features & Use Cases - Deterministic preflight verification: Runs static discovery, source-installed skill parity, hook payload comparison, and capability regression checks against a disposable nested Git fixture. - Optional three-tier live profile: With explicit --create, builds one real local task-board GUI, Django/Gunicorn server, and PostgreSQL database through the normal SDLC workflow, performs computer-use GUI UAT, then destroys every exactly owned Docker resource. - Lifecycle management: Supports --create --keep, --resume, and standalone --destroy with fail-closed ownership labels, immutable verification-ID fencing, and idempotent ALREADY_DESTROYED results. - Use Case: After changing the SDLC design doc or hook source, run the no-flag verifier to get a PASS/PARTIAL/FAIL report confirming whether the workflow is safe to try on a low-risk repository. ## Quick Start Ask the agent to run the sdlc-workflow-test skill with no flags to verify the Agentic SDLC workflow and produce a readiness report.
