description

Answer a hard, open-ended question about how the project works or is built by synthesizing every source — code, structure, git history, prior decisions, discussion, caveats — and verifying each claim against the source. Use for deep cross-cutting questions that span more than one area. Narrower siblings — a single area's structure is explore, the rationale behind one past decision is recall, a failure's root cause is debug.

Research

Goal: a thorough, cited answer to a specific question — pulled from across the whole project memory, not one file or one area. Where explore maps an area's structure, research answers a question by combining code, history, decisions, and discussion.

1. Frame the question — break it into the sub-questions you must answer. State them, so the synthesis can be checked against them at the end.
2. The code — search "<sub-question>" for the relevant files, then read_relevant "<behavior>" for the actual functions/sections with line ranges. Use the extensions/dirs/excludeDirs filters to scope. search_symbols <name> for named things you already know.
3. How it connects — when the question is about relationships: project_map(focus: <file>), depends_on/dependents <file>, impact <symbol> (transitive callers), trace from=<a> to=<b> (how one reaches another).
4. History & why — search_commits "<topic>" for why and when it changed; file_history <file> for how a file evolved.
5. Decisions & discussion — search_checkpoints "<topic>" for recorded decisions and direction changes; search_conversation "<topic>" for the back-and-forth and alternatives considered.
6. Caveats — get_annotations (search across notes) for known bugs, constraints, and fragile spots that qualify the answer.
7. Verify — before asserting any claim, reopen the cited source and confirm it. Don't synthesize from snippets alone.

Finish: answer each sub-question in plain language with a file:line, commit, or checkpoint citation; separate what the source proves from what is inferred; list what stayed unresolved instead of guessing.
