output-style-to-plugin

Convert deprecated Claude Code output style markdown files into properly structured plugins using SessionStart hooks. This skill handles the complete conversion process automatically, requiring only essential information from the user.

When to Use This Skill

Use this skill when:

• Converting an existing output style .md file to plugin format
• Migrating from the deprecated outputStyle configuration to the plugin system
• Setting up a new plugin-based output style from scratch
• User asks to "convert output style to plugin" or similar migration requests

Conversion Workflow

Step 1: Gather Required Information

Ask the user for essential information before starting the conversion. Use the AskUserQuestion tool to collect:

1. Output Style File: Path to the existing output style .md file
2. Plugin Name: Identifier for the plugin (suggest kebab-case version of file name)
3. Plugin Description: Brief description (can extract from output style frontmatter if present)
4. Version: Default to "1.0.0" for initial conversion
5. Author Name: Plugin author's name
6. Author Email (optional): Author's email address

Example questions:

Question: "What is the path to your output style markdown file?"
Question: "What would you like to name this plugin? (e.g., 'my-output-style')"
Question: "Brief description of this output style?"
Question: "Author name for the plugin?"
Question: "Author email? (optional, press Enter to skip)"

Step 2: Check for Existing Marketplace

Before creating a new marketplace, check if the user has an existing marketplace they want to use:

1. Ask: "Do you have an existing marketplace you'd like to add this plugin to?"
2. If yes:
   • Ask for marketplace path
   • Read the existing marketplace/.claude-plugin/marketplace.json
   • Extract marketplace name and owner information
   • Plan to add plugin entry to existing plugins array
3. If no:
   • Collect marketplace information:
     • Marketplace name (suggest based on user context)
     • Owner name (suggest same as plugin author)
     • Owner email (suggest same as plugin author email)
   • Plan to create new marketplace structure
