When and How to Recall
NOTE
Having memories is meaningless without using them.
A mechanism to retrieve the right memory at the right time is needed.
Memory Retrieval Patterns
1. Automatic Loading at Session Start
Information in CLAUDE.md is automatically loaded every session. Most reliable, but constantly consumes context budget.
2. Conditional Loading
Like .claude/rules/, memories are loaded under specific conditions (file operations). Budget-efficient.
3. On-Demand Loading
Like Skills, memories are retrieved only when needed. Triggered by user or LLM decision.
4. Loading via External Tools
Memories stored externally are retrieved through MCP servers or memory tools.
Design Principles
- Frequently needed memory → CLAUDE.md (always available)
- Memory tied to file type → Rules (conditional)
- Task-specific memory → Skills (on-demand)
- Long-term knowledge → External memory tools
