deja-vu
Search your past AI coding sessions — Claude Code, Codex, Cursor and 17 more. Indexes the session history they already wrote to disk, including months from before you installed it, and recalls it in any of them. No LLM, no embeddings, one local Go binary.

Why we included this project
Anyone who has watched Claude Code or Codex re-debug something they already fixed months ago will recognize the pain this solves. deja-vu reads the session logs those coding agents already write to disk, builds a local search index, and hands the relevant past decision back to the agent over MCP, with no LLM, no embeddings, just a single Go binary. Because it indexes history that already exists, it is useful from the first install rather than starting empty and recording forward. Recall is triggered automatically at session start, before file edits, and after failed commands, with keys and tokens stripped as the index is built. Teams that want their coding agents to stop repeating past mistakes without shipping session data to a third-party service will find this a practical option.
