What it does and how to use it

A specialized AI agent for general. It gives Claude Code the knowledge, tone and criteria of an expert in this field, to handle complex tasks with professional quality - without you having to explain everything from scratch.

  1. Install the agent with the command above, in your project folder.
  2. Open Claude Code and describe the task in plain language.
  3. Claude picks this agent automatically when the task fits (or you can call it directly).
  4. Review the result and iterate - the agent keeps the context.

mkdir -p .claude/agents && curl -fsSL https://doutorai.pt/data/lib/agents__0xfurai-subagents__agents-jest-expert.md -o .claude/agents/0xfurai-subagents__agents-jest-expert.md

Paste this command into the terminal, in your project folder, and the component installs automatically.
