declick compiles an OpenAPI spec, an MCP server, a database or a web page into named shell verbs the model loads one at a time, each returning a single envelope with five exit codes. Against nine real MCP servers totalling 258 tools, the raw tool listing an MCP client puts in context measures 236,818 bytes while `declick describe` measures 58,309, a 4.1x reduction reproducible with `node scripts/bench-tokens.mjs`.
