## /CLAUDE.md
# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Project Overview
This is a curated collection of Claude Code subagent definitions - specialized AI assistants for specific development tasks. Subagents are markdown files with YAML frontmatter that Claude Code can load and use.
## Repository Structure
```
categories/
01-core-development/ # Backend, frontend, fullstack, mobile, etc.
02-language-specialists/ # Language/framework experts (TypeScript, Python, etc.)
03-infrastructure/ # DevOps, cloud, Kubernetes, etc.
04-quality-security/ # Testing, security auditing, code review
05-data-ai/ # ML, data engineering, AI specialists
06-developer-experience/ # Tooling, documentation, DX optimization
07-specialized-domains/ # Blockchain, IoT, fintech, gaming
08-business-product/ # Product management, business analysis
09-meta-orchestration/ # Multi-agent coordination
10-research-analysis/ # Research and analysis specialists
```
## Subagent File Format
Each subagent follows this template:
```yaml
---
name: agent-name
description: When this agent should be invoked (used by Claude Code for auto-selection)
tools: Read, Write, Edit, Bash, Glob, Grep # Comma-separated tool permissions
---
You are a [role description]...
[Agent-specific checklists, patterns, guidelines]
## Communication Protocol
[Inter-agent communication specs]
## Development Workflow
[Structured implementation phases]
```
### Tool Assignment by Role Type
- **Read-only** (reviewers, auditors): `Read, Grep, Glob`
- **Research** (analysts): `Read, Grep, Glob, WebFetch, WebSearch`
- **Code writers** (developers): `Read, Write, Edit, Bash, Glob, Grep`
- **Documentation**: `Read, Write, Edit, Glob, Grep, WebFetch, WebSearch`
## Contributing a New Subagent
When adding a new agent, update these files:
1. **Main README.md** - Add link in appropriate category (alphabetical order)
2. **Category README.md** - Add detailed description, update Quick Selection Guide table
3. **Agent .md file** - Create the actual agent definition
Format for main README: `- [**agent-name**](path/to/agent.md) - Brief description`
## Subagent Storage in Claude Code
| Type | Path | Scope |
|------|------|-------|
| Project | `.claude/agents/` | Current project only |
| Global | `~/.claude/agents/` | All projects |
Project subagents take precedence over global ones with the same name.
## /CONTRIBUTING.md
# Contributing to Awesome Claude Subagents

1. **Choose the right category** - Place your subagent in the most appropriate category folder
2. **Test your subagent** - Ensure it works with Claude Code
3. **Update required files** - When adding a new agent, you must update:
- **Main README.md**: Add your agent to the appropriate category section in alphabetical order
- **Category README.md**: Add detailed description, update Quick Selection Guide table, and if applicable, Common Technology Stacks
- **Your agent .md file**: Create the actual agent definition following the template
4. **Submit a PR** - Include a clear description of the subagent's purpose
### Subagent Requirements
Each subagent should include:
- Clear role definition
- List of expertise areas
- Required MCP tools (if any)
- Communication protocol examples
- Core capabilities
- Example usage scenarios
- Best practices
### Required Updates When Adding a New Agent
When you add a new agent, you MUST update these files:
1. **Main README.md**
- Add your agent link in the appropriate category section
- Maintain alphabetical order
- Format: `- [**agent-name**](path/to/agent.md) - Brief description`
2. **Category README.md** (e.g., `categories/02-language-specialists/README.md`)
- Add detailed agent description in the "Available Subagents" section
- Update the "Quick Selection Guide" table
- If applicable, add to "Common Technology Stacks" section
3. **Your Agent File** (e.g., `categories/02-language-specialists/your-agent.md`)
- Follow the standard template structure
- Include all required sections
### Versioning Requirements for Plugin Updates
When you modify existing plugin content, you MUST bump versions so users can receive updates via `claude plugin update`.
1. **Bump category plugin version**
- File: `categories/<category>/.claude-plugin/plugin.json`
- Increment `version` whenever any `*.md` file in that category changes.
2. **Keep marketplace plugin versions in sync**
- File: `.claude-plugin/marketplace.json`
- Update the corresponding plugin entry version to match the category plugin version.
### Adding a Tool
Tools are Claude Code skills that enhance the catalog experience (discovery, browsing, management).
1. **Create a folder** in `tools/` with your tool name
2. **Include required files**:
- `README.md` - Installation and usage documentation
- Command files (`.md`) - One per command, with YAML frontmatter
- Helper scripts (`.sh`, `.py`) - Shared utilities if needed
3. **Follow skill best practices**:
- Use descriptive `name` and `description` in frontmatter
- Include trigger phrases in descriptions
- Handle errors gracefully with user-friendly messages
4. **Update the main README.md** - Add your tool to the 🧰 Tools section
5. **Test locally** before submitting

## 🤖 Understanding Subagents
Subagents are specialized AI assistants that enhance Claude Code's capabilities by providing task-specific expertise. They act as dedicated helpers that Claude Code can call upon when encountering particular types of work.
### What Makes Subagents Special?
**Independent Context Windows**
Every subagent operates within its own isolated context space, preventing cross-contamination between different tasks and maintaining clarity in the primary conversation thread.
**Domain-Specific Intelligence**
Subagents come equipped with carefully crafted instructions tailored to their area of expertise, resulting in superior performance on specialized tasks.
**Shared Across Projects**
After creating a subagent, you can utilize it throughout various projects and distribute it among team members to ensure consistent development practices.
**Granular Tool Permissions**
You can configure each subagent with specific tool access rights, enabling fine-grained control over which capabilities are available for different task types.
### Core Advantages
- **Memory Efficiency**: Isolated contexts prevent the main conversation from becoming cluttered with task-specific details
- **Enhanced Accuracy**: Specialized prompts and configurations lead to better results in specific domains
- **Workflow Consistency**: Team-wide subagent sharing ensures uniform approaches to common tasks
- **Security Control**: Tool access can be restricted based on subagent type and purpose
### Getting Started with Subagents
**1. Access the Subagent Manager**
```bash
/agents
```
**2. Create Your Subagent**
- Choose between project-specific or global subagents
- Let Claude generate an initial version, then refine it to your needs
- Provide detailed descriptions of the subagent's purpose and activation triggers
- Configure tool access (leave empty to inherit all available tools)
- Customize the system prompt using the built-in editor (press `e`)
**3. Deploy and Utilize**
Your subagent becomes immediately available. Claude Code will automatically engage it when suitable, or you can explicitly request its help:
```
> Have the code-reviewer subagent analyze my latest commits
```
### Subagent Storage Locations
| Type | Path | Availability | Precedence |
|------|------|--------------|------------|
| Project Subagents | `.claude/agents/` | Current project only | Higher |
| Global Subagents | `~/.claude/agents/` | All projects | Lower |
Note: When naming conflicts occur, project-specific subagents override global ones.
## 📖 Subagent Structure
Each subagent follows a standardized template:
```yaml
---
name: subagent-name
description: When this agent should be invoked
tools: Read, Write, Edit, Bash, Glob, Grep
model: sonnet
---
You are a [role description and expertise areas]...
[Agent-specific checklists, patterns, and guidelines]...
## Communication Protocol
Inter-agent communication specifications...
## Development Workflow
Structured implementation phases...
```
### Tool Assignment Philosophy
### Smart Model Routing
Each subagent includes a `model` field that automatically routes it to the right Claude model — balancing quality and cost:
| Model | When It's Used | Examples |
|-------|----------------|----------|
| `opus` | Deep reasoning — architecture reviews, security audits, financial logic | `security-auditor`, `architect-reviewer`, `fintech-engineer` |
| `sonnet` | Everyday coding — writing, debugging, refactoring | `python-pro`, `backend-developer`, `devops-engineer` |
| `haiku` | Quick tasks — docs, search, dependency checks | `documentation-engineer`, `seo-specialist`, `build-engineer` |
You can override any agent's model by editing the `model` field in its frontmatter. Set `model: inherit` to use whatever model your main conversation is using.
### Tool Assignment Philosophy
Each subagent's `tools` field specifies Claude Code built-in tools, optimized for their role:
- **Read-only agents** (reviewers, auditors): `Read, Grep, Glob` - analyze without modifying
- **Research agents** (analysts, researchers): `Read, Grep, Glob, WebFetch, WebSearch` - gather information
- **Code writers** (developers, engineers): `Read, Write, Edit, Bash, Glob, Grep` - create and execute
- **Documentation agents** (writers, documenters): `Read, Write, Edit, Glob, Grep, WebFetch, WebSearch` - document with research
Each agent has minimal necessary permissions. You can extend agents by adding MCP servers or external tools to the `tools` field.
## 🧰 Tools
