About
A free local plugin that runs tool output in a local sandbox, keeps the full output in a per-project SQLite index, and gives the agent only the part it asks for — median reply 99.4% smaller on big outputs. Works with 10 coding agents. Plugin free forever, zero telemetry, works offline after install.
