Install the Deep Research skill

A community skill: it installs from its own repository and your agent runs the project's instructions locally with your own model. SkillGild lists it and credits the author; nothing runs on SkillGild.

  1. With the SkillGild CLI (needs git). It clones 199-biotechnologies/claude-deep-research-skill and copies the skill folder into the right place for your agent; use --agent codex, cursor or gemini-cli for other clients.

    Terminal
    skillgild install deep-research --agent claude-code
  2. Manual copy.

    Terminal
    git clone https://github.com/199-biotechnologies/claude-deep-research-skill.git ~/.claude/skills/deep-research
  3. Or copy the folder yourself from 199-biotechnologies/claude-deep-research-skill into ~/.claude/skills/deep-research/ for Claude Code, ~/.agents/skills/ for Codex, ~/.cursor/skills/ for Cursor or ~/.gemini/skills/ for Gemini CLI, then start a new session.

Questions

How do I install the Deep Research skill in Claude Code?

Run skillgild install deep-research --agent claude-code: the SkillGild CLI clones 199-biotechnologies/claude-deep-research-skill and copies the skill folder into ~/.claude/skills/deep-research. You can also use the project's own commands shown above, or copy the folder yourself. Use --agent codex, cursor or gemini-cli for other clients.

Is Deep Research free and open source?

The 199-biotechnologies/claude-deep-research-skill repository does not include a license file at the time of listing, so treat it as all rights reserved by the author until one is added. SkillGild lists and links it; it does not host or redistribute the files.

Which agents does Deep Research work with?

The project lists Claude Code. It is a plain Agent Skills folder (SKILL.md plus supporting files), so any client that reads that format can load it.

Does Deep Research run on SkillGild?

No. Deep Research is a community skill: your agent runs its instructions locally with your own model, and SkillGild lists, credits and installs it. Hosted SkillGild skills are marked differently and run through the SkillGild MCP server.

What does Deep Research need to work?

Optional search provider keys (Brave, Serper, Exa, Jina, Firecrawl). Everything else is the usual: a coding agent that loads skills and the folder installed where that agent looks for it.
