## Memory System

At the START of every session:
1. Read `.claude/memory/MEMORY.md` to load the master index
2. Load topic files relevant to the current task
3. Check the activity log for recent session context

At the END of every session:
1. Update `.claude/memory/activity-log.md` with: date, work done, decisions made, next steps
2. Update any topic files that changed (new patterns, resolved incidents, etc.)
3. If a new topic file was created, add it to `MEMORY.md` index

Rules:
- Keep `MEMORY.md` under 200 lines (it is an index, not a dump)
- Use relative links between memory files
- Be specific in incident runbooks (include exact error messages)
- Cross-reference between files when relevant
