Trellis requirements-to-delivery entrypoint and workflow controller. Use when the user wants to invoke one Trellis skill that detects the current stage and routes work across requirements analysis, MVP task planning, post-MVP gap audit, delivery loop, TDD implementation, systematic debugging, two-stage review, and final acceptance. Coordinates trellis-zero-to-mvp, trellis-mvp-to-delivery, trellis-implement-tdd, trellis-debug-systematic, and trellis-review-twostage while enforcing safety gates.
