Runs in five phases: interview to establish scope, decompose the topic into angles, research each angle in parallel, synthesize a cited report, then deliver it.

Phase 1 — Interview

Interview the user relentlessly until the topic is fully pinned. Cover:

The core question or topic
Scope boundaries (what's in, what's explicitly out)
Known context or prior work to skip
Desired depth (quick overview vs. exhaustive)
Output preference: inline report in the conversation, or written to files in a directory (get a directory path)

Ask one question at a time. If a question can be answered by exploring the project, do that instead of asking.

Stop only when scope is unambiguous and output preference is confirmed.

Phase 2 — Decompose

Break the topic into research angles (typically 3–6) — enough to cover the topic's distinct facets, with minimal overlap between angles, without spreading any single researcher too thin to reach depth. For each angle, state:

deep-research
