• bdd-generate — Scaffold pytest-bdd feature files and step definitions from acceptance criteria
• tdd-workflow — Enforce red-green-refactor discipline with test-first development
• verification-stack — Run automated quality gates (format, lint, type check, test) as deterministic verification
• beads-workflow — Track work items with the Beads CLI (bd commands) with explicit dependencies
