Project Notes
Maintain a persistent knowledge base about the project. Claude reads this at the start of relevant tasks to have context without you re-explaining.
When to use
- "Remember that we use Postgres, not MySQL"
- "What do we know about the auth system?"
- "Add this to project notes"
- "What conventions do we follow?"
- When starting work on a project area you haven't touched in a while
Paths
| What | Path |
|---|
| Notes directory | $PROJECT_ROOT/notes/ |
| Architecture notes | $PROJECT_ROOT/notes/architecture.md |
| Conventions | $PROJECT_ROOT/notes/conventions.md |
| Decisions log | $PROJECT_ROOT/notes/decisions.md |
How to execute
Reading notes
ls $PROJECT_ROOT/notes/
cat $PROJECT_ROOT/notes/architecture.md
Adding a note
Append to the appropriate file, or create a new topic file:
## [Topic] (YYYY-MM-DD)
**Decision:** [What was decided]
**Context:** [Why this decision was made]
**Alternatives considered:** [What else was considered]
Note categories
| File | What goes here |
|---|
architecture.md | System design, service boundaries, data flow |
conventions.md | Naming, file structure, coding standards |
decisions.md | ADRs — why we chose X over Y |
integrations.md | External services, API keys location, endpoints |
troubleshooting.md | Known issues and their fixes |
Examples
Adding a decision
## Use Redis for caching (2024-03-15)
**Decision:** Use Redis instead of in-memory caching
**Context:** App runs on multiple instances, need shared cache
**Alternatives:** Memcached (less features), in-memory (no sharing)
Adding a convention
## API Response Format
All API endpoints return:
\```json
{
"data": {...},
"error": null,
"meta": {"timestamp": "...", "request_id": "..."}
}
\```
Tips
- Keep notes concise — bullet points over paragraphs
- Include dates — context changes over time
- Link to code —
src/auth/middleware.ts:45 is better than "the auth middleware"
- Delete outdated notes — stale context is worse than no context
