Researches a question, evaluates its own findings, and iterates until the answer is complete and cited.

Summary

The Deep Search Agent takes a research question, searches the web, and then critiques its own findings — re-searching to close gaps until the question is fully answered. It returns an answer grounded only in the sources it found, with a citation for every claim. Reach for it whenever a single search isn't enough and you need a verified, sourced answer.

Installation

$ pnpm dlx shadcn@latest add @agentcn/eve/deep-search

Customization

  • Search provider. Searches run through the Bright Data SERP API — real-time, unblocked results billed per successful request. Set BRIGHTDATA_API_KEY (and optionally BRIGHTDATA_SERP_ZONE). Edit agent/tools/web_search.ts to point at a different provider — keep the input/output shape.
  • Bound the iterations. Add a max-rounds guard in instructions.md so the agent stops after N search rounds.
  • Swap the model. Edit agent/agent.ts — anthropic/claude-sonnet-4-6 for deeper synthesis, anthropic/claude-haiku-4-5 for speed.
  • Add scraping. Add a scrape_url tool so the agent can read full pages, not just search snippets.
