System Lifecycle Skill
Triggers
- lifecycle
- traceability
- requirement
- golden thread
- definition of done
- verify requirements
Purpose
To ensure every line of code has a reason (Requirement) and a verification method (Test).
Capabilities
1. The Golden Thread (Traceability)
- Link:
REQ-ID->Design Element->Code Component->Test Case. - Gap Analysis: Find requirements with no tests, or code with no requirements.
2. Definition of Done (DoD) Enforcement
- Checklist:
- Implementation matches Spec?
- Tests pass?
- Documentation updated?
- Traceability Matrix updated?
3. Change Impact Analysis
- Query: "If I change
UserAuth.ts, what Requirements are affected?" - Action: Reverse trace from Code -> Req to find impact scope.
Instructions
- Always ID Requirements: Use
REQ-001,REQ-002formatting in PRDs. - Tag Tests: Add
@req(REQ-001)annotations to test functions/classes. - Maintain Matrix: Update
TRACEABILITY_MATRIX.mdas you code.
Deliverables
TRACEABILITY_MATRIX.md: The living map of the system.impact-analysis.md: Report on proposed changes.
