SummarySkillFlow is an open multi-stage retrieval pipeline (dense retrieval, two cross-encoder rerankings, LLM selection) that pulls relevant skills from ~35K community-contributed SKILL.md files for coding agents. On SkillsBench it raises Pass@1 from 9.2% to 16.4%; on Terminal-Bench it shows high use but no gain, indicating corpus quality matters.
Why it mattersConcrete open-source retrieval stack for agent skill libraries, with measured gains and a candid null result on a second benchmark that exposes when retrieval alone is not enough.
