Research

Deep research is a loop, not a search. Plan, then repeat query-search-extract-synthesize until evidence covers the question, then report with citations. Tools differ per runtime; the loop does not. Load references/tools.md when invoking concrete search or fetch tools, and references/report-format.md before writing the report.

Step 1 - Plan

1. Restate the question as one sentence. If it is ambiguous, ask before searching.
2. Split it into 3-6 sub-questions that together answer it.
3. Classify the report: factual, comparison, product, how-to, fact-check, explainer.
4. Set the round cap by complexity: simple 2, moderate 3, complex 5. The cap is a ceiling, not a target.

Step 2 - Date grounding

Inject the current date before any search. LLMs default to training-cutoff years and query stale terms. Any query needing a year uses the current year.
