What it does

When installed, this skill tells the agent to research a complex question more thoroughly than usual. It expands the question into focus areas, scans several kinds of sources (such as Exa search, GitHub, arXiv papers, blogs and documentation), groups notes by theme, and then writes a structured answer. The answer includes a short summary, key findings, a pros and cons table, recommendations, and a list of sources.

Great for

  • Developers comparing frameworks, languages or tools before choosing one
  • Analysts preparing market or competitor overviews
  • Students or researchers who want a first structured survey of a topic with sources listed

Skip it if

  • Quick factual questions, where the extra steps add time without value
  • Situations needing verified, up-to-date facts without checking: the skill only instructs the agent to gather sources, and the agent may still summarise inaccurately or miss recent material
  • Legal, medical or financial decisions, where the output is a synthesis and should be checked by a qualified professional

Try asking

  • “Research the trade-offs between PostgreSQL and MongoDB for a high-write analytics app and list sources”
  • “Compare three open-source vector databases for a small team, with a pros and cons table”
  • “Survey recent papers and blog posts on retrieval-augmented generation and summarise the main findings”
