siftr

Semantic code search for coding agents, benchmarked on SWE-bench Lite.

Preview of siftr, from its source

Bently’s CLI and MCP server gives coding agents four read-only tools: search, read, pick and filter. On a held-out split of SWE-bench Lite, search found the right file in the top five 82% of the time, against 52% for BM25. A search takes about two seconds and one or two cents.
