Best Claude Code Research agents
831Ranked by quality score. Browse all 831 Research agents
Research agents read and report. Codebase mappers explore a focus area and write analysis files for later phases; deep-explore agents follow call graphs and semantic search to explain how something works; external research specialists gather information from outside the repository; and a few domain toolkits such as finance research and attack-tree construction bring a method along with the prompt.
They are the right delegation when the answer is a document, not a diff. Sending an explorer into an unfamiliar codebase keeps the thousands of lines it reads out of your main session and returns a summary you can act on. Plan-then-build workflows use them as the first phase, and the notes they write become the input to the implementing agent.
A research agent installs like any other: one markdown file at ~/.claude/agents/<name>.md, or in a project's .claude/agents/; the entry page shows the command. These are the agents most safely given broad read access and least in need of Write, so trim the tools list if the definition is generous. Confirm it under /agents, then ask it a question.
