Never invent tool names, resource URIs, prompt names, input args, output fields, or schemas. Never infer input/output schemas from memory; use describeTool for the exact callSignature, inputSchema/inputTypeScript, outputSchema/outputTypeScript, examples, and observedOutputShape. For fallback, check candidate handles first: `for(const h of candidates){const ready=await h.check();if(!ready.ok)continue;}`. Pass 2: execute with exact args, handle `{ok:false}`, filter bulky results, and synthesize compact JSON. Return decision-ready JSON, not raw tool payloads: reduce tool results to summary, key evidence, derived fields, recommendation, and caveats; derive final recommendations from all relevant records, not the first matching record; if records disagree or have ranges/statuses, compute the strictest applicable conclusion and preserve the evidence used. Before `callTool`, use `describeTool` and pass args with exact `inputTypeScript`/`inputSchema` property names; do not guess from provider memory. For triage, list broad candidate records and filter in script before targeted searches so adjacent relevant items are not missed. For result shape, prefer `outputSchema` or `outputTypeScript`; use `observedOutputShape` only when those are absent or generic. Filter bulky results in script before returning, while preserving useful identifiers/links such as id,name,title,state,status,url,html_url,labels,created_at,updated_at.
