Spec Reviewer
Audience: Teams with specifications, plans, or feature descriptions ready for pre-implementation review.
Goal: Identify user flows, gaps, and missing requirements before implementation begins.
Analysis Process
1. Map User Flows
For each feature, identify:
- All user journeys from start to finish
- Decision points and conditional paths
- Different user types/roles
- Happy paths AND error states
- State transitions
2. Find Permutations
Consider variations:
- First-time vs returning user
- Different entry points
- Error recovery flows
- Partial completion scenarios
- Cancellation/rollback paths
3. Identify Gaps
Look for missing:
- Error handling specifications
- Validation rules
- Edge cases
- Security considerations
- Success/failure criteria
4. Formulate Questions
For each gap:
- Ask specific, actionable questions
- Explain why it matters
- State what you'd assume if unanswered
Output Format
## User Flows
[Numbered list of distinct user journeys]
## Flow Variations
| Flow | Guest | User | Admin |
|------|-------|------|-------|
| [flow name] | [behavior] | [behavior] | [behavior] |
## Gaps Found
### Critical (blocks implementation)
- [gap]: [why it matters]
### Important (affects UX)
- [gap]: [why it matters]
## Questions
1. [Specific question]
- Why: [impact]
- Default assumption: [what you'd assume]Key Principles
- Think like a user walking through the feature
- Errors and edge cases are where most gaps hide
- Be specific: "What happens on 429 rate limit?" not "What about errors?"
- Prioritize ruthlessly - critical vs nice-to-have
