Plan Interview Plugin

Interview-driven specification generation with quality review. Transform rough plans into comprehensive, implementation-ready specifications through adaptive, structured interviews.

Features

• Adaptive Interview (/plan-interview:interview) - Automatically adjusts depth based on plan complexity
• Spec Reviewer Agent - Autonomous quality analysis of specifications
• Smart Hooks - Auto-suggests interview after plan creation
• Reference Library - Deep-dive resources for each interview phase

Installation

/plugin install plan-interview@claude-skills

Or add to your project:

cp -r plugins/plan-interview ~/.claude/plugins/

Command

/plan-interview:interview [plan]

Adaptive interview that calibrates depth based on plan complexity:

Complexity	Signals	Question Count
Simple	Single feature, clear scope, minimal integrations	10-15 questions
Moderate	Multi-component, some integrations, defined boundaries	18-23 questions
Complex	Cross-system, many stakeholders, unclear boundaries	22-28 questions

Interview Phases:

1. Foundations & Scope (4-6 questions)

   • Stakeholder analysis
   • Success/failure criteria
   • Constraint exploration
   • Prior art investigation
   • Dependency mapping
   • MVP scope definition

2. Technical Deep-Dive (5-7 questions)

   • Architecture decisions
   • Data models & state
   • Scalability exploration
   • Technical debt assessment
   • Observability planning
   • Security considerations

3. User Experience (4-6 questions)

   • User persona depth
   • Cognitive load analysis
   • Emotion mapping
   • Failure recovery UX
   • Onboarding & learning curve

4. Risks & Tradeoffs (3-5 questions)

   • Risk categorization
   • Blast radius analysis
   • Reversibility assessment
   • Contingency planning

5. Operationalization (2-3 questions)

   • Testing strategy
   • Deployment plan
   • Monitoring & observability

6. Wrap-Up (0-1 questions, optional)

   • Only for complex plans with gaps

Spec Reviewer Agent

After generating a spec, the spec-reviewer agent analyzes quality across 4 dimensions:

• Completeness (25 pts) - All sections populated?
• Consistency (25 pts) - No contradictions?
• Clarity (25 pts) - No ambiguous language?
• Edge Cases (25 pts) - Error handling defined?

Triggers when you:

• Say "review my spec" or "check specification quality"
• Generate a spec (proactively offered at session end)

Output includes quality score (A-F), issues by severity, and recommended fixes.

Reference Library

The plugin includes deep-dive references for each phase:

Reference	Purpose
references/phase-1-clarifications.md	15+ example questions, common pitfalls
references/phase-2-technical.md	Architecture discussion patterns
references/phase-3-ux.md	Persona development, UX patterns
references/phase-4-risks.md	Risk assessment frameworks
references/interview-techniques.md	Cross-cutting interview skills
references/example-spec.md	Annotated high-quality spec example

These are loaded by the interviewer as needed for deeper guidance.

Smart Hooks

The plugin includes hooks that:

• Suggest running interview when *plan*.md files are created
• Offer spec review before session ends (if spec was generated)

Interview Philosophy

Core Principle: Depth over breadth. Better to deeply understand critical aspects than superficially cover everything.

Key Techniques:

• Non-obvious questions - Skip anything the plan already answers
• Edge probing - What happens in unusual cases?
• Assumption surfacing - Make implicit beliefs explicit
• Contradiction detection - Flag when answers don't align
• Concrete examples - "Give me a specific scenario..."
• Follow-through - Dig deeper when complexity emerges
• Adaptive depth - Probe deeper on complex areas, move faster on clear ones

Spec Output Format

Generated specs include:

• Overview: Problem, solution, success criteria, key stakeholders
• Requirements: Functional and non-functional
• Technical Design: Architecture, data models, APIs, scalability, security
• User Experience: Personas, flows, states, edge cases
• Risks & Mitigations: Risk register, accepted tradeoffs, contingency plans
• Implementation Notes: Key decisions with rationale, dependencies
• Operationalization: Testing, deployment, monitoring
• Open Questions: Unresolved items needing decisions
• Out of Scope: Explicitly excluded items
• Phasing: MVP vs future enhancements

Example Workflow

# 1. You have a rough plan
cat docs/auth-plan.md

# 2. Run adaptive interview
/plan-interview:interview docs/auth-plan.md

# 3. Claude assesses complexity and announces approach
# "This looks like a moderate-complexity plan. I'll ask 18-23 questions."

# 4. Answer questions interactively (one at a time)
# Interview adapts depth based on your answers

# 5. Output: docs/auth-plan-spec.md

# 6. Review quality (automatic or manual)
# "Review the spec I just created"
# Output: Quality report with score and issues
