Installation

These subagents are automatically available when placed in ~/.claude/agents/ directory.

Usage

Automatic Invocation

Claude Code will automatically delegate to the appropriate subagent based on the task context and the subagent's description.

Explicit Invocation

Mention the subagent by name in your request:

"Use the code-reviewer to check my recent changes"

Subagent Format

Each subagent follows this structure:

---
name: subagent-name
description: When this subagent should be invoked
tools: tool1, tool2  # Optional - defaults to all tools
---

System prompt defining the subagent's role and capabilities

Best Practices

1. Let Claude Code delegate automatically - The main agent knows when to use each subagent
2. Use explicit invocation for specific needs - When you want a particular expert's perspective
3. Combine multiple subagents - Complex tasks may benefit from multiple specialists

Contributing

To add a new subagent:

1. Create a new .md file following the format above
2. Use lowercase, hyphen-separated names
3. Write clear descriptions for when the subagent should be used
4. Include specific instructions in the system prompt
