Create Memory

Create Memory Files

Track important learnings and decisions in .claude/memory/ files.

When to Use

• Just implemented major feature or system
• Made important architectural decision
• Discovered critical project patterns
• User says "remember this" or "track this"
• Solved complex bug with important learnings
• Established new workflow or standard

After Creating Memory File

1. Add to CLAUDE.md imports:

## [Section Name]

@.claude/memory/new-file-name.md

2. Verify import:

grep "new-file-name" CLAUDE.md

Best Practices

• Be specific - Don't create vague "notes.md" files
• Include examples - Code examples make it memorable
• Date it - Track when learnings happened
• Update existing - Prefer updating existing memory over creating new
• Reference files - Link to actual code files affected
• Mark status - Is this current? Deprecated? In progress?

Memory File Lifecycle

1. Create - When major learning happens
2. Update - As patterns evolve
3. Reference - Import in CLAUDE.md
4. Deprecate - Mark outdated when patterns change
5. Archive - Delete if truly obsolete (rare)

Memory vs Documentation

Memory files are for Claude, not users:

• Internal patterns and decisions
• "Why we do X instead of Y"
• Critical learnings from past mistakes
• Project-specific conventions

Documentation is for users:

• README.md
• API docs
• User guides

Keep them separate.
