Spec Writing Research

Use with /ccpm:plan:

When writing specs, docs-seeker finds authoritative sources:

User: "/ccpm:plan DOC-789 api-design"

Claude: [docs-seeker activates]

Researching API design best practices...

Finding documentation:
1. RESTful API design guide (Microsoft)
2. GraphQL schema design (Apollo)
3. OpenAPI 3.1 specification
4. API versioning strategies

Recommendations based on docs:
- Endpoints: Use nouns, not verbs (/users not /getUsers)
- Versioning: URL path (/v1/) or Accept header
- Pagination: Cursor-based for scalability
- Error handling: RFC 7807 Problem Details
- Documentation: OpenAPI spec + Swagger UI

Writing API design section with these guidelines...

Implementation Guidance

During feature implementation:

User: "How do I implement file uploads with NextJS 15?"

Claude: [docs-seeker activates]

Searching Next.js 15 file upload documentation...

Found official guides:
1. Next.js App Router: Route Handlers
2. FormData API usage
3. File upload best practices
4. Streaming uploads for large files

Implementation approach:
```typescript
// app/api/upload/route.ts
export async function POST(request: Request) {
  const formData = await request.formData();
  const file = formData.get('file') as File;

  // Process file
  const bytes = await file.arrayBuffer();
  const buffer = Buffer.from(bytes);

  // Save to storage
  await saveFile(buffer, file.name);

  return Response.json({ success: true });
}

## Documentation Sources

### Official Sources (Highest Priority)

**Always check official docs first**:
- Framework documentation (React, Next.js, Vue, Angular)
- Library docs (Lodash, Axios, Moment.js)
- Cloud provider docs (AWS, GCP, Azure)
- API specifications (Stripe, Twilio, SendGrid)

### Technical Specifications

**For standards and protocols**:
- W3C specifications
- IETF RFCs
- ECMA standards
- OpenAPI/Swagger specs

### Community Resources

**When official docs are insufficient**:
- MDN Web Docs (JavaScript, CSS, HTML)
- Stack Overflow discussions
- GitHub repositories and READMEs
- Technical blogs (reputable sources only)

## Search Strategies

### Strategy 1: Version-Specific Search

Always search for the specific version in use:

❌ Generic: "React hooks documentation" ✅ Specific: "React 19 hooks documentation"

❌ Generic: "Node.js async/await" ✅ Specific: "Node.js 20 async/await best practices"

### Strategy 2: Context-Aware Search

Include the context of what you're building:

❌ Vague: "authentication docs" ✅ Context: "JWT authentication with Express.js and Passport"

❌ Vague: "database queries" ✅ Context: "PostgreSQL complex joins with Prisma ORM"

### Strategy 3: Progressive Discovery

Start broad, then narrow down:

1. **Overview**: "What is Server Components in React?"
2. **API Reference**: "Server Component API methods"
3. **Integration**: "Server Components with Next.js App Router"
4. **Best Practices**: "Server Components performance optimization"

## Examples

### Example 1: Research for Spec Writing

User: "/ccpm:plan DOC-456 architecture"

Claude: [docs-seeker activates]

Researching architecture patterns for payment processing...

Finding documentation:

1. Stripe API documentation

   • Payment Intents API
   • Webhook handling
   • Idempotency keys

2. PCI compliance requirements

   • Never store full card numbers
   • Use tokenization
   • Secure data transmission

3. Architecture patterns

   • Adapter pattern for multiple providers
   • Event-driven webhooks
   • Retry mechanisms with exponential backoff

4. Error handling

   • Stripe error types
   • Declined payments flow
   • Network timeout handling

Documentation summary:

• Use Payment Intents (not legacy Charges API)
• Implement webhook signature verification
• Store payment status in database
• Handle idempotency for retries
• Support multiple payment providers via adapters

Writing architecture section with these patterns...

### Example 2: Quick Implementation Help

User: "How do I use React useEffect with async functions?"

Claude: [docs-seeker activates]

Searching React useEffect async documentation...

Found: React 19 documentation on useEffect

Official recommendation:

// ✅ Correct approach
useEffect(() => {
  async function fetchData() {
    const response = await fetch('/api/data');
    const data = await response.json();
    setData(data);
  }
  fetchData();
}, []);

// ❌ Wrong - useEffect cannot be async directly
useEffect(async () => {
  // This won't work!
}, []);

Key points from docs:

• useEffect callback cannot be async
• Create async function inside useEffect
• Handle cleanup with AbortController
• Avoid race conditions with cleanup

Documentation: https://react.dev/reference/react/useEffect#fetching-data-with-effects

Would you like me to show the full pattern with cleanup?

### Example 3: API Integration Research

User: "Find Stripe webhook documentation"

Claude: [docs-seeker activates]

Searching Stripe webhook documentation...

Found official Stripe docs:

1. Webhook Events

   • payment_intent.succeeded
   • payment_intent.payment_failed
   • customer.subscription.updated
   • Full event reference: https://stripe.com/docs/api/events/types

2. Webhook Security

   • Signature verification required
   • Use Stripe-Signature header
   • Verify with webhook secret
   • Code example:

   const sig = request.headers['stripe-signature'];
   const event = stripe.webhooks.constructEvent(
     request.body,
     sig,
     process.env.STRIPE_WEBHOOK_SECRET
   );
   

3. Best Practices

   • Return 200 immediately
   • Process events asynchronously
   • Handle duplicate events (idempotency)
   • Log all webhook events
   • Monitor webhook failures in Stripe dashboard

4. Testing

   • Use Stripe CLI for local testing
   • Test with Stripe's test events
   • Verify all event types your app handles

Documentation: https://stripe.com/docs/webhooks

This should be added to the implementation plan under "Webhook Handler" section.
