Codex Deep Research

Use this skill when the user is asking for research rather than a normal answer. Typical triggers include:

• comparisons, evaluations, and recommendations
• market scans, competitive analysis, and landscape research
• questions where current information materially affects the answer
• requests that need citations, trade-offs, risks, or explicit source quality

Do not force the full workflow onto simple factual questions. First decide whether the task truly needs deep research.

Quick start

1. Rewrite the request into a compact internal research brief.
2. Browse early and prefer current, verifiable sources.
3. Stay single-agent unless there is a real quality benefit to parallel work.
4. If complexity is high, delegate distinct sub-questions to a small number of sub-agents using the sub-agent template.
5. Deliver a complete research report in the current conversation unless the user explicitly asks for a shorter format.
6. Only save files when the user asks or the result is clearly worth preserving after the in-session report is complete.
