What Deja History does

Deja History searches past AI coding sessions on this machine to recover prior decisions, fixes, and context. Use it before re-debugging or re-implementing something that may already have been solved.

Deja History is cataloged under AI Engineering on DirSkills. Deja History comes from a repository tagged agent-memory, ai-memory, antigravity, bm25 and claude.

Documentation

README

Excerpt

Search deja before re-deriving past work: when the user refers to earlier sessions or decisions, before debugging an error, and before implementing something that may already exist. It searches this machine's own history across every AI coding tool used on it, going back further than deja itself was installed.

If these tools are not available in this session, the same index is reachable through the shell: deja search --json "<query>", deja ctx <query>, deja blame <path> --json.
