Migration Guide

OpenClaw → Claude Code

# Convert SKILL.md to skill.json
import json
import yaml

with open('SKILL.md') as f:
    content = f.read()
    
# Extract frontmatter
frontmatter = yaml.safe_load(content.split('---')[1])

skill_json = {
    'name': frontmatter['name'],
    'version': frontmatter['version'],
    'permissions': convert_permissions(frontmatter.get('permissions', [])),
    'tools': build_tools_from_instructions(content)
}

with open('skill.json', 'w') as f:
    json.dump(skill_json, f, indent=2)

VS Code → Cursor

# Update package.json structure
jq '.manifest = .contributes | del(.contributes)' package.json > manifest.json

# Convert activation events to permissions
# Update TypeScript implementation for Cursor
