Deep Research

This orchestrates OpenAI's o4-mini-deep-research model to handle comprehensive research tasks with web search. It's clever about prompt enhancement: if you throw it something brief like "latest AI trends," it asks 2-3 clarifying questions about scope and depth before running the actual research. Saves everything to timestamped files for reproducibility. The workflow is token-efficient because deep research takes 10-20 minutes, so it just blocks and waits rather than polling for status updates. Best for when you need actual investigation with sources, not just a quick answer. The technical versus general research detection is a nice touch for tailoring follow-up questions.

Deep Research Skill

Purpose

This skill enables comprehensive, internet-enabled research on any topic using the OpenAI Responses API with web search (default model gpt-5.6-sol, override with --model or DEEP_RESEARCH_MODEL). o3-deep-research and o4-mini-deep-research were scheduled for shutdown on 2026-07-23 and are no longer the default. It intelligently enhances user research prompts through interactive clarifying questions, ensures research parameters are saved for reproducibility, and executes deep research with full web search capabilities.
