Execute extract and use project memories from previous sessions for context-aware assistance. Use when recalling past decisions, checking project conventions, or understanding user preferences. Trigger with phrases like "remember when", "like before", or "what was our decision about".

Memory provides persistent context across Claude Code sessions by storing and retrieving project decisions, user preferences, and coding conventions from a local JSON file. When a new session starts, stored memories load automatically so previously established patterns carry forward without re-explanation.
.claude/memories/project_memory.json (created automatically on first memory save).claude/memories/ directory/plugin install yldrmahmet/claude-never-forgets).claude/memories/project_memory.json using the Read tool. Parse the JSON structure containing timestamped memory entries. See ${CLAUDE_SKILL_DIR}/references/implementation.md for the full retrieval workflow./remember command or through automatic capture of conversation signals.hooks/stop_cleanup.py./memories command| Error | Cause | Solution |
|---|---|---|
| Memory file not found | First session or file deleted | Initialize a new memory file at .claude/memories/project_memory.json with an empty JSON structure |
| Conflicting memories | Multiple entries contradict each other | Apply the most recent memory; suggest cleanup via /forget to remove outdated entries |
| Invalid memory format | File corrupted or manually edited with syntax errors | Back up the existing file, recreate with valid JSON structure, restore recoverable entries |
| Permission denied | File or directory lacks read/write permissions | Check file permissions on .claude/memories/; request necessary access or use an alternative storage location |
Automatic preference recall across sessions:
Session 1:
User: "Always use Vitest instead of Jest for this project"
→ Stored to project_memory.json
Session 2:
User: "Add tests for the auth module"
→ Memory loaded: "use Vitest instead of Jest"
→ Test files created with Vitest syntax automatically
Manual memory management:
/remember "This project uses Tailwind CSS v4 with the Vite plugin"
/remember "Deploy to Cloudflare Workers, not Vercel"
/memories # Lists all stored memories with timestamps
/forget "Vercel" # Removes the Vercel-related memory
Tool rejection captured as correction:
set -euo pipefail
User declines a suggested `npm install` action
→ Memory stored: "User prefers pnpm over npm"
→ Future sessions use pnpm automatically
