Local-first persistent memory CLI for coding agents
Project description
deja
Local-first persistent memory CLI for coding agents. Memories accumulate across sessions, deduplicate automatically, and stay on your machine.
Install
uv tool install deja-cli
Quick Start
deja init # first-time setup
deja setup claude-code # inject memory instructions into Claude Code
Core Commands
Save a memory:
deja save "Always use explicit error handling over try/catch" --type preference
deja save "Auth tokens stored in localStorage, not cookies" --type decision --project myapp
deja save "Prisma migrations fail silently if DB_URL has wrong port" --type gotcha --project myapp
Load at session start:
deja load --project myapp --context "what you're working on"
Search mid-session:
deja search "authentication" --project myapp
Extract memories from a session:
deja save-session --project myapp
