Production Checklist

• All errors use core error types
• Error messages are helpful but don't leak sensitive info
• Only log error messages when wrapping into core errors
• No stack traces exposed to users
• Proper HTTP status mapping to core errors

3. Code Quality

• Build passes with exit code 0
• All tests pass (unit and integration)
• No lint errors or warnings
• No TypeScript errors
• No use of ! (non-null assertion)
• All mappers use const output: Type pattern

4. Documentation

• USERGUIDE.md complete with:
  • How to obtain credentials
  • Connection profile structure
  • Required permissions
  • Troubleshooting section
• README.md only if special requirements
• All operations documented in API spec
• Examples work correctly

5. API Specification

• All 12 critical rules followed
• No root-level servers or security
• All properties camelCase
• Pagination using standard patterns
• All operations from original request implemented

6. Implementation

• ConnectionState.yml if needed (tokens, sessions)
• All mappers validate required fields
• PagedResults uses manual assignment
• No environment variables used
• Proper type imports from core packages

7. Testing

• Integration tests prepared (may fail without creds)
• Unit tests with sanitized fixtures
• No skipped tests
• No .only() in tests
• Test data sanitized (no PII)
• Read-only operations tested on production when possible

8. Examples

• Connection example works
• At least one operation example works
• Examples use realistic data
• Examples don't contain real credentials

🟡 WARNINGS - Should Be Fixed

Performance

• Reasonable timeout values
• No unnecessary API calls
• Efficient pagination handling

Maintenance

• Clear code structure
• Consistent naming
• No commented-out code
• No console.log statements

🟢 NICE TO HAVE

Developer Experience

• Helpful error messages
• Clear function names
• Logical file organization
• Consistent patterns

Validation Commands

Run these before marking complete:

# Security check
grep -r "password\|secret\|key\|token" src/ --exclude="*.ts"

# Build validation
npm run clean
npm run build

# Test validation
npm run test
npm run test:integration

# Lint check
npm run lint

# Check for console.log
grep -r "console.log" src/

# Check for non-null assertions
grep -r "!" src/ | grep -v "!=" | grep -v "!=="

# Check for skipped tests
grep -r ".skip\|.only" test/

Sign-off Criteria

✅ Module is ready when:

1. All mandatory items checked
2. Build and tests pass
3. Documentation complete
4. Examples work
5. No security issues
6. No breaking changes to existing operations

Important Reminders

• Never write to production during testing unless explicitly required
• Never log sensitive data even in development
• Always validate inputs before using them
• Always use core error types never generic Error
• Always follow the rules even if external API doesn't

Logging Policy

What to log:

• Error messages when wrapping to core errors

What NOT to log:

• Request/response bodies
• Headers with auth info
• Any credentials
• User data
• Debug information
• Performance metrics

No logging for:

• Health checks
• Metrics
• Debug mode
• Observability

The module should be silent except for errors.
