## What it does

This skill provides reference guides and instructions for setting up isolated Claude Code sub-agents. It covers interactive setup with `/agents`, CLI definitions via `--agents`, and Markdown configuration files inside `.claude/agents/` or `~/.claude/agents/`. The skill operates using `Read`, `Write`, and `Bash`.

Agents are configured with YAML frontmatter specifying `name`, `description`, `tools`, and `model`, followed by a markdown system prompt. The reference maps Haiku to fast searches, Sonnet to general tasks by default, and Opus to deep reasoning. Project-level definitions in `.claude/agents/` take priority over global files in `~/.claude/agents/`, which ensures team settings override local user defaults.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill sub-agents -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/sub-agents/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/sub-agents/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill sub-agents -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/sub-agents/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill sub-agents -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/sub-agents/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install parcadei/Continuous-Claude-v3 sub-agents
```

2. **Manually: put the files in place**
- File: `.github/skills/sub-agents/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill sub-agents -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/parcadei/Continuous-Claude-v3 --path .claude/skills/sub-agents
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/sub-agents/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill sub-agents -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/parcadei/Continuous-Claude-v3/tree/HEAD/.claude/skills/sub-agents/SKILL.md

## When to use it
- configure sub-agents with custom system prompts and isolated contexts
- restrict tool access for specialized review or debugging workflows
- assign specific models (Haiku, Sonnet, Opus) across different tasks
- chain agents together to run multi-step code analysis and fixes

## Example prompts
- How do I create a sub-agent for code review?
- Configure agent tools and pick the right model
- What built-in agents exist in Claude Code?

# Sub-Agents Reference

Create specialized AI agents with isolated contexts for specific tasks.

## When to Use

- "How do I create a sub-agent?"
- "Configure agent tools"
- "What built-in agents exist?"
- "Agent model selection"
- "Agent chaining patterns"

## Quick Start

### Interactive (Recommended)
```bash
/agents
```
Opens menu to create, edit, and manage agents.

### Manual Creation
```bash
mkdir -p .claude/agents
cat > .claude/agents/reviewer.md << 'EOF'
---
name: reviewer
description: Code review specialist. Use proactively after code changes.
tools: Read, Grep, Glob, Bash
model: sonnet
---

You are a senior code reviewer focusing on quality and security.

## Review Checklist
- Code clarity and naming
- Error handling
- Security vulnerabilities
- Test coverage
EOF
```

### CLI-Based
```bash
claude --agents '{
  "reviewer": {
    "description": "Code reviewer",
    "prompt": "Review for quality and security",
    "tools": ["Read", "Bash"],
    "model": "sonnet"
  }
}'
```

## Agent File Format

```yaml
---
name: agent-name
description: When/why to use this agent
tools: Read, Edit, Bash      # Optional, inherits all if omitted
model: sonnet                 # sonnet, haiku, claude-opus-4-5-20251101, inherit
---

```

## Configuration Fields

| Field | Required | Options |
|-------|----------|---------|
| `name` | Yes | lowercase, hyphens |
| `description` | Yes | When to use |
| `tools` | No | Tool list (inherits all if omitted) |
| `model` | No | `sonnet`, `haiku`, `claude-opus-4-5-20251101`, `inherit` |

## Built-In Agents

| Agent | Model | Tools | Purpose |
|-------|-------|-------|---------|
| General-purpose | Sonnet | All | Complex multi-step tasks |
| Plan | Sonnet | Read-only | Plan mode research |
| Explore | Haiku | Read-only | Fast codebase search |

## Model Selection

| Model | Speed | Best For |
|-------|-------|----------|
| Haiku | Fastest | Search, quick lookups |
| Sonnet | Fast | Most tasks (default) |
| Opus | Slower | Complex reasoning |

## Tool Combinations

```yaml
# Code Reviewer (read-only)
tools: Read, Grep, Glob, Bash

# Debugger
tools: Read, Edit, Bash, Grep, Glob

# Implementer
tools: Read, Write, Edit, Bash, Glob
```

## Example Agents

### Code Reviewer
```yaml
---
name: code-reviewer
description: Reviews code for quality and security. Use after code changes.
tools: Read, Grep, Glob, Bash
model: sonnet
---

Review code for:
- Security vulnerabilities
- Code quality issues
- Missing error handling
- Test coverage gaps

Output findings by priority: Critical > Warning > Suggestion
```

### Debugger
```yaml
---
name: debugger
description: Debug errors and test failures.
tools: Read, Edit, Bash, Grep, Glob
model: inherit
---

Debugging process:
1. Capture error details
2. Identify failure location
3. Form hypotheses
4. Test and verify
5. Implement fix
```
