scaffold

name: scaffold description: | Component scaffolding toolkit for creating skills, agents, commands, and hooks within the unified wicked-garden plugin. Generates complete, valid structures that pass validation out-of-the-box. Use when creating new domain components, setting up boilerplate, or ensuring proper structure from the start.

Scaffold Tool

Quick-start generator for wicked-garden domain components.

Purpose

Generates production-ready component structures within the unified plugin:

• Skills - SKILL.md with proper YAML frontmatter and refs/ directory
• Agents - Agent .md files with tools and frontmatter
• Commands - Slash commands with YAML frontmatter
• Hooks - hooks.json entries with Python scripts

All scaffolded components pass validation immediately.

Usage

Interactive Mode

python .claude/skills/scaffolding/scripts/scaffold.py

# Interactive prompts:
# > Component type? (skill/agent/command/hook)
# > Domain? (crew, engineering, platform, ...)
# > Name? (kebab-case)
# > Description?

# Result:
# Skill created: skills/crew/my-skill/
# Namespace: wicked-garden:crew:my-skill

Command Line Mode

# Skill
python .claude/skills/scaffolding/scripts/scaffold.py skill \
  --name my-skill \
  --domain crew \
  --description "What this skill does"

# Agent
python .claude/skills/scaffolding/scripts/scaffold.py agent \
  --name my-agent \
  --domain platform \
  --description "What this agent does" \
  --tools "Read,Write,Bash"

# Command
python .claude/skills/scaffolding/scripts/scaffold.py command \
  --name my-command \
  --domain engineering \
  --description "What this command does"

# Hook
python .claude/skills/scaffolding/scripts/scaffold.py hook \
  --event PreToolUse \
  --script validate-tool-use \
  --description "Validates tool usage"

Generated Paths

Components are placed in domain-specific subdirectories:

wicked-garden/                    # Plugin root
├── skills/{domain}/{name}/       # Skills
│   └── SKILL.md
├── agents/{domain}/{name}.md     # Agents
├── commands/{domain}/{name}.md   # Commands
├── hooks/scripts/{name}.py       # Hook scripts
└── hooks/hooks.json              # Hook bindings (updated)

Naming Conventions

• Commands: wicked-garden:{domain}:{command} (colon-separated)
• Agents: wicked-garden:{domain}/{agent} (slash for agent path)
• Skills: wicked-garden:{domain}:{skill} (colon-separated)

Command Template Selection

When scaffolding a command, the tool checks if agents/{domain}/*.md exists:

• If agents exist: Uses command-with-agent.md template with Task(subagent_type=...) dispatch
• If no agents: Uses inline command.md template

This ensures new commands follow the delegation standard from the start.

Skill Template

Hook Template

hooks.json

{
  "hooks": [
    {
      "event": "{event}",
      "script": "scripts/{script-name}.py",
      "description": "{description}",
      "enabled": true
    }
  ]
}

Hook Script

#!/usr/bin/env python3
"""
{Event} hook for {plugin-name}.

Exit codes:
  0 - Success, continue
  2 - Blocking error (message sent to Claude)
  Other - Non-blocking error (logged)
"""

import sys
import json
import os

def main():
    # Read hook data from stdin
    try:
        data = json.loads(sys.stdin.read())
    except json.JSONDecodeError:
        print("Error: Invalid JSON input", file=sys.stderr)
        sys.exit(1)

    # Hook logic here
    # Access: data['tool'], data['arguments'], data['context']

    # Example validation
    if data.get('tool') == 'Bash':
        command = data.get('arguments', {}).get('command', '')
        if 'rm -rf /' in command:
            print("Blocked dangerous command: rm -rf /")
            sys.exit(2)  # Block execution

    # Allow execution
    sys.exit(0)

    main()

Valid Domains

The 16 domains in wicked-garden:

Workflow & Intelligence: crew, smaht, mem, search, jam, kanban Specialist Disciplines: engineering, product, platform, qe, data, delivery, agentic, persona

Domains are discovered dynamically from commands/ — new domains are valid immediately.

Best Practices

Naming

• Use kebab-case for all names
• Max 64 characters
• No reserved prefixes (claude-code-, anthropic-, official-)
• Plugin names should start with wicked- for marketplace consistency

Structure

• Put reusable logic in scripts/
• Use commands/ for user-facing operations
• Use skills/ for Claude expertise
• Use agents/ for specialized subagents

Documentation

• Write clear, concise descriptions
• Include usage examples
• Document dependencies
• Explain configuration options

Security

• All scripts should use ${CLAUDE_PLUGIN_ROOT} for paths
• Quote shell variables: "$VAR"
• Validate input before processing
• No hardcoded secrets
