## Component Types & Validation Rules

### 1. AGENTS (cli-tool/components/agents/)

**Format**: Markdown (`.md`) with YAML frontmatter

**Required Fields**:
- `name`: kebab-case identifier
- `description`: Clear, comprehensive description of capabilities
- `tools`: Comma-separated list (Read, Write, Edit, Bash, etc.)
- `model`: Model version (sonnet, haiku, opus, inherit)

**Content Requirements**:
- Clear system prompt explaining the agent's role
- Specific focus areas or capabilities
- Best practices and guidelines
- No hardcoded secrets or API keys

**Validation Checklist**:
- [ ] YAML frontmatter is valid and complete
- [ ] Name uses kebab-case (lowercase with hyphens)
- [ ] Description is clear and specific (not generic)
- [ ] Tools are specified appropriately
- [ ] Content provides detailed instructions
- [ ] No hardcoded secrets (API keys, tokens, passwords)
- [ ] No absolute paths (use relative paths like `.claude/scripts/`)
- [ ] File is in correct category directory

**Example Structure**:
```markdown
---
name: frontend-developer
description: Frontend development specialist for React applications and responsive design
tools: Read, Write, Edit, Bash
model: sonnet
---

You are a frontend developer specializing in modern React applications...
```

### 2. COMMANDS (cli-tool/components/commands/)

**Format**: Markdown (`.md`) with YAML frontmatter

**Required Fields**:
- `allowed-tools`: Specific bash commands permitted (e.g., `Bash(git add:*)`)
- `argument-hint`: Usage syntax showing expected arguments
- `description`: Clear command purpose

**Content Requirements**:
- Command usage examples
- Current state queries (using `!` syntax for dynamic values)
- Options and flags documentation
- Error handling guidance

**Validation Checklist**:
- [ ] YAML frontmatter is valid and complete
- [ ] Name uses kebab-case
- [ ] `allowed-tools` specifies permitted commands
- [ ] `argument-hint` shows clear usage syntax
- [ ] Description is specific and actionable
- [ ] Examples demonstrate proper usage
- [ ] No hardcoded secrets
- [ ] No absolute paths

**Example Structure**:
```markdown
---
allowed-tools: Bash(git add:*), Bash(git status:*), Bash(git commit:*)
argument-hint: [message] | --no-verify | --amend
description: Create well-formatted commits with conventional commit format
---

# Smart Git Commit

Create well-formatted commit: $ARGUMENTS
```

### 3. HOOKS (cli-tool/components/hooks/)

**Format**: JSON (`.json`) + optional supporting scripts (`.py`, `.sh`)

**Required Fields**:
- `description`: Hook purpose and behavior
- `hooks`: Object with event types (PreToolUse, PostToolUse, etc.)

**Hook Configuration**:
- `matcher`: Tool pattern ("*", "Bash", "Read", "Write", etc.)
- `type`: "command", "script", or "python"
- `command`: Command to execute

**Validation Checklist**:
- [ ] JSON is valid and properly formatted
- [ ] Name uses kebab-case
- [ ] Description explains hook behavior
- [ ] Hook matchers are valid tool names
- [ ] Commands reference correct paths
- [ ] Supporting scripts exist if referenced
- [ ] Supporting scripts have correct extensions (.py, .sh)
- [ ] No hardcoded secrets in JSON or scripts
- [ ] Scripts use relative paths

**Example Structure**:
```json
{
  "description": "Prevent direct pushes to protected branches",
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Bash",
        "hooks": [
          {
            "type": "command",
            "command": "python3 \"$CLAUDE_PROJECT_DIR\"/.claude/hooks/script.py"
          }
        ]
      }
    ]
  }
}
```

**Supporting Scripts Validation**:
- If hook references a `.py` or `.sh` file, verify it exists in the same directory
- Script names should match the hook name pattern
- Scripts must be executable for `.sh` files
