Ready-to-use subagent files for Claude Code. Copy any agent file to your project's .claude/agents/ directory (or to ~/.claude/agents/ for personal use across all projects) and it becomes available immediately.
Install a single agent into your project:
cp agents/code-reviewer.md .claude/agents/Install all core agents into your project:
mkdir -p .claude/agents
cp agents/*.md .claude/agents/Install agents from a category:
mkdir -p .claude/agents
cp agents/language-specialists/*.md .claude/agents/Install an agent for personal use across all projects:
mkdir -p ~/.claude/agents
cp agents/code-reviewer.md ~/.claude/agents/Reload agents without restarting Claude Code:
/agents
Use an agent directly:
Use the code-reviewer agent to review my recent changes.
Trigger auto-delegation - agents with "use proactively" in their description will be selected automatically when you describe a matching task:
Review this code for security issues before I open a PR.
These 12 agents ship with the repo at the top level of agents/.

- Agents listed in
.claude/agents/(project scope) are committed to git and shared with your team. - Agents in
~/.claude/agents/(user scope) are personal and available in every project. - The
descriptionfield controls when Claude auto-delegates. Be specific about trigger conditions. - You can install agents from any category subdirectory - just copy the
.mdfiles to.claude/agents/. - Community agents use standard Claude Code agent format with frontmatter (name, description, tools, model).
