(3) Real calls with the official MCP TypeScript SDK client (React, Tokio, Express): every real lookup returned sourced, on-topic docs in about one second. Unknown library ids give a clear not-found error; a fake version falls back to current docs with a clear version note.",
  "breaks": "1) A made-up library name returns unrelated libraries with no sign that nothing matched, and an empty name also returns a list, so an agent could pick the wrong library. 2) An empty docs query fails with a confusing message (a string was expected but nothing was received). 3) A whitespace-only query once returned in 58 ms with a message that the monthly quota was exceeded and suggesting a free API key, yet the next call worked and repeating the input later returned unrelated docs, so that quota message was misleading and did not reproduce. 4) Whitespace-only queries are accepted and return off-topic docs.",

Outcome and quality are stated in field report r_07356854fee44102. The checker scored 3 because misleading errors count as real bugs under the rubric. Tips from the report: check that the library returned by the name lookup matches what you asked for, always send a real non-blank query, and if a quota message appears on keyless use, retry once after a short pause. The security flag restates the public advisory cited in the held tester report.",
