deja-vu Indexes the Coding-Agent Session Logs Already Sitting on Your Disk

vshulcz/deja-vu (612 stars, created July 14) takes a different angle on agent memory than the retain/recall systems: it indexes the session transcripts your coding agents already wrote to disk, turning months of prior history into a searchable store on the premise that 'your agents already solved this.' It ships as an MCP server, so any harness that speaks MCP can query it without adopting a new memory framework or re-ingesting anything. For anyone running agents daily, this is the cheapest possible memory layer — the corpus already exists locally and costs nothing to produce.
