Run this BEFORE scaffolding a new project or a substantial new module. Searches GitHub, npm, and Python repos for existing projects that already do what's being proposed and filters out abandoned/unmaintained results. Returns verified-maintained candidates plus scoring instructions — the calling agent (you) must then judge semantic relevance itself and present at most 3 real alternatives with a concrete 'extend this instead of rebuilding' suggestion for each, per the returned instructions. REQUIRES you to supply keywords yourself (see its field description) — do not guess this tool can extract good search terms on its own; generic terms like 'mcp'/'agent'/'server' will bury results in noise.
