CLAUDE.md Update Guidelines
Core Principle
Only add information that will genuinely help future Claude sessions. The context window is precious - every line must earn its place.
What TO Add
1. Commands/Workflows Discovered
## Build
`npm run build:prod` - Full production build with optimization
`npm run build:dev` - Fast dev build (no minification)Why: Saves future sessions from discovering these again.
2. Gotchas and Non-Obvious Patterns
## Gotchas
- Tests must run sequentially (`--runInBand`) due to shared DB state
- `yarn.lock` is authoritative; delete `node_modules` if deps mismatchWhy: Prevents repeating debugging sessions.
3. Package Relationships
## Dependencies
The `auth` module depends on `crypto` being initialized first.
Import order matters in `src/bootstrap.ts`.Why: Architecture knowledge that isn't obvious from code.
4. Testing Approaches That Worked
## Testing
For API endpoints: Use `supertest` with the test helper in `tests/setup.ts`
Mocking: Factory functions in `tests/factories/` (not inline mocks)Why: Establishes patterns that work.
5. Configuration Quirks
## Config
- `NEXT_PUBLIC_*` vars must be set at build time, not runtime
- Redis connection requires `?family=0` suffix for IPv6Why: Environment-specific knowledge.
What NOT to Add
1. Obvious Code Info
Bad:
The `UserService` class handles user operations.The class name already tells us this.
2. Generic Best Practices
Bad:
Always write tests for new features.
Use meaningful variable names.This is universal advice, not project-specific.
3. One-Off Fixes
Bad:
We fixed a bug in commit abc123 where the login button didn't work.Won't recur; clutters the file.
4. Verbose Explanations
Bad:
The authentication system uses JWT tokens. JWT (JSON Web Tokens) are
an open standard (RFC 7519) that defines a compact and self-contained
way for securely transmitting information between parties as a JSON
object. In our implementation, we use the HS256 algorithm which...Good:
Auth: JWT with HS256, tokens in `Authorization: Bearer <token>` header.Diff Format for Updates
For each suggested change:
1. Identify the File
File: ./CLAUDE.md
Section: Commands (new section after ## Architecture)2. Show the Change

+## Commands

+| Command | Purpose |
+|---------|---------|
+| `npm run dev` | Dev server with HMR |
+| `npm run build` | Production build |
+| `npm test` | Run test suite |3. Explain Why
Why this helps: The build commands weren't documented, causing confusion about how to run the project. This saves future sessions from needing to inspect
package.json.
Validation Checklist
Before finalizing an update, verify:
- Each addition is project-specific
- No generic advice or obvious info
- Commands are tested and work
- File paths are accurate
- Would a new Claude session find this helpful?
- Is this the most concise way to express the info?
