Phase 0: Start

Shows the complete development workflow and validates your project is ready to begin.

Command: /0-start

When to use

Run this at the very beginning of any development project, or when you want to see the full workflow sequence. It is also the entry point when returning to a project after a break -- the checkpoint system will detect where you left off.

What happens

  1. Checkpoint detection -- If a .claude-checkpoint.md exists, displays your last completed phase and suggests resuming from there.
  2. Branch enforcement -- Checks you are on a feature branch (not main/master). Creates one if needed.
  3. Prerequisite scan -- Looks for PRD.md, CLAUDE.md, project structure, SpecKit setup (.specify/), and repo governance (.repo-manifest.yaml).
  4. Recommendation -- Based on what it finds (empty directory, PRD only, fully bootstrapped project), tells you exactly what to do next.

Output

  • A workflow diagram showing all seven phases
  • A prerequisite report (what exists, what is missing)
  • A quick-reference card for all workflow commands
  • A concrete next-step suggestion
