- Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name.

When to Use
Use this skill when:
- Starting non-trivial changes
- Coordinating spec, design, implementation, and validation
- Running command-based SDD flow
---
Canonical Phase Order
1. `explore` - understand existing behavior and constraints 2. `propose` - define intent and scope 3. `apply` - implement tasks from approved plan 4. `verify` - validate behavior against spec and regressions 5. `archive` - capture completion and close loop
Never skip a phase without explicit rationale.
---
Artifacts per Phase
- Explore: findings and risks
- Propose: change proposal with scope boundaries
- Apply: code + tests
- Verify: evidence of validation
- Archive: finalized summary and follow-ups
---
Exit Criteria
- [ ] Scope and risks understood before implementation
- [ ] Tests prove expected behavior
- [ ] Verification covers regressions
- [ ] Session summary captures learnings for next work
