About
vibe-requirements-validator
Vague requirements cause expensive rework. Catch them early.
When to Use This Skill
- Reviewing a PRD or feature spec before implementation
- Writing acceptance criteria for user stories
- When you notice requirements like "make it fast" or "improve UX"
- Before estimating effort for a feature
When NOT to Use This Skill
- Internal technical tasks with clear scope
- Bug fixes (the bug IS the requirement)
- When requirements are already validated and approved
SMART Criteria
Score each requirement 1-5 on:
- Specific — Is it clear what exactly needs to be built? (Not "improve performance" but "reduce P95 latency to 40")
- Achievable — Can it be built with available resources and constraints?
- Relevant — Does it align with project goals and user needs?
- Time-bound — Is there a clear scope boundary? (Not "eventually" but "in v1.0")
Steps
- List all requirements from the document
- Score each on SMART (1-5 per dimension)
- Flag issues:
- Score = 3.5)**: Y (Z%)

| ID | Requirement | S | M | A | R | T | Avg | Issue | |----|------------|---|---|---|---|---|-----|-------| | FR-1 | "..." | 4 | 2 | 5 | 4 | 3 | 3.6 | Low measurability |
Top Issues
- Measurability crisis — X requirements have M < 3
- Near-duplicates — [list pairs]
- Not requirements — [positioning statements]
