Marketplace Creation Workflow

Guide the user through creating a complete plugin marketplace from initial concept to validated, distributable collection. Follow a systematic approach: understand requirements, plan plugins, configure structure, add entries, validate, and prepare for distribution.

Core Principles

• Ask clarifying questions: Identify all ambiguities about marketplace purpose, plugins, distribution strategy. Ask specific questions rather than making assumptions. Wait for user answers before proceeding.
• Load marketplace-structure skill: Use the Skill tool to load the marketplace-structure skill for schema and pattern guidance
• Use plugin-validator agent: Leverage the plugin-validator agent for comprehensive marketplace validation
• Follow best practices: Apply patterns from this repository's own marketplace.json
• Use Task tools: Track all progress throughout all phases using TaskCreate, TaskUpdate, and TaskList

Phase 1: Discovery

Goal: Understand what marketplace needs to be created and its purpose

Actions:

1. Create task list with all 8 phases
2. If marketplace purpose is clear from arguments:
   • Summarize understanding
   • Identify marketplace type (team internal, community, single-plugin, multi-plugin)
3. If marketplace purpose is unclear, ask user:
   • What plugins will this marketplace contain?
   • Who is the target audience? (team, community, public)
   • Will plugins be local (in same repo) or external (GitHub, git URLs)?
   • Single maintainer or community contributions?
4. Summarize understanding and confirm with user before proceeding

Output: Clear statement of marketplace purpose and distribution strategy

---

Phase 2: Plugin Planning

Goal: Determine which plugins to include and their sources

MUST load marketplace-structure skill using Skill tool before this phase.

Actions:

1. Load marketplace-structure skill for schema guidance

2. List plugins to include in marketplace:

   • For each plugin: name, source type, brief description

3. Categorize by source type:

   • Local (relative path): Plugins maintained in same repository
   • GitHub: External plugins on GitHub
   • Git URL: External plugins on GitLab, Bitbucket, or self-hosted

4. Present plugin plan to user as table:

   | Plugin Name      | Source Type | Description            |
   |------------------|-------------|------------------------|
   | code-formatter   | local       | Code formatting tools  |
   | security-scanner | github      | Security analysis      |
   | legacy-tool      | git-url     | Legacy utility         |
   

5. For each local plugin, determine:

   • Does it already exist? (will validate)
   • Need to create it? (redirect to /plugin-dev:create-plugin)

6. Get user confirmation or adjustments

Output: Confirmed list of plugins with sources

---

Phase 3: Metadata Design

Goal: Define marketplace metadata and owner information

Actions:

1. Determine marketplace name:

   • Must be kebab-case (lowercase, hyphens)
   • Should be descriptive of purpose
   • Examples: team-tools, security-plugins, awesome-claude-plugins

2. Gather owner information:

   • Ask user: "Who maintains this marketplace?"
   • Required: name
   • Optional: email, url

3. Define optional metadata:

   • description: Brief marketplace description
   • version: Initial version (recommend 1.0.0 or 0.1.0)
   • pluginRoot: Base path for relative sources (default: none)

4. Present configuration summary:

   {
     "name": "team-tools",
     "owner": {
       "name": "Platform Team",
       "email": "platform@company.com"
     },
     "metadata": {
       "description": "Internal development tools",
       "version": "1.0.0"
     }
   }
   

5. Get user confirmation

Output: Confirmed marketplace metadata

---

Phase 4: Structure Creation

Goal: Create marketplace directory structure and manifest

Actions:

1. Determine marketplace location:

   • Ask user: "Where should I create the marketplace?"
   • Offer options: current directory, new directory, custom path

2. Create directory structure using bash:

   mkdir -p marketplace-name/.claude-plugin
   mkdir -p marketplace-name/plugins  # if local plugins
   

3. Create marketplace.json manifest using Write tool:

   {
     "name": "marketplace-name",
     "owner": {
       "name": "[from Phase 3]"
     },
     "metadata": {
       "description": "[from Phase 3]",
       "version": "[from Phase 3]"
     },
     "plugins": []
   }
   

4. Create README.md template with:

   • Marketplace description
   • Installation instructions
   • Available plugins table (to be filled in Phase 5)
   • Contributing guidelines (if community)

5. Initialize git repo if creating new directory (only git init is available; additional git operations like staging and committing are left to the user after the workflow completes to respect their commit preferences)

Output: Marketplace directory structure created

Post-workflow git operations (user can run after completion):

git add .
git commit -m "feat: initial marketplace structure"

---

Phase 5: Plugin Entry Configuration

Goal: Configure each plugin entry with appropriate metadata

Actions:

1. For each plugin in the plan (from Phase 2):

   For local plugins:

   • If plugin exists:
     • Read its plugin.json to get metadata
     • Create entry with relative source path
   • If plugin doesn't exist:
     • Ask: "Plugin 'X' doesn't exist. Create it now or add placeholder?"
     • If create: Use Task tool to run /plugin-dev:create-plugin
     • If placeholder: Create entry with TODO comment in README

   For GitHub plugins:

   • Create entry with github source object
   • Prompt for version, description if not known
   • Consider strict: false if plugin lacks plugin.json

   For git URL plugins:

   • Create entry with url source object
   • Prompt for version, description if not known

2. For each entry, configure optional fields:

   • version (recommend always including)
   • description (recommend always including)
   • category (if marketplace uses categories)
   • tags (for discoverability)

3. Update marketplace.json with all plugin entries

4. Update README.md with plugin table:

   Plugin	Description	Version
   X	Does Y	1.0.0

Output: All plugin entries configured in marketplace.json

---

Phase 6: Distribution Setup

Goal: Configure distribution strategy based on target audience

Actions:

1. For team/internal marketplaces:

   • Provide team settings configuration:

     {
       "extraKnownMarketplaces": {
         "marketplace-name": {
           "source": {
             "source": "github",
             "repo": "org/marketplace-repo"
           }
         }
       }
     }
     

   • Document which plugins should be in enabledPlugins

   • Add to README: How team members install

2. For community/public marketplaces:

   • Create CONTRIBUTING.md with:
     • Plugin submission guidelines
     • Review process
     • Quality requirements
   • Create CI workflow for validation (optional):
     • JSON syntax check
     • Required field validation
     • Duplicate name detection

3. For all marketplaces:

   • Document installation command in README:

     /plugin marketplace add owner/repo
     

   • List individual plugin installation:

     /plugin install plugin-name@marketplace-name
     

Output: Distribution documentation complete

---

Phase 7: Validation

Goal: Ensure marketplace meets quality standards

Actions:

1. Run plugin-validator agent:

   • Use plugin-validator agent to validate marketplace
   • Check: schema, required fields, plugin entries, source paths

2. Fix critical issues:

   • Address any critical errors from validation
   • Fix warnings that indicate real problems

3. Validate local plugins (if any):

   • For each local plugin, run plugin validation
   • Fix any issues found

4. Check best practices:

   • All entries have version
   • All entries have description
   • README documents all plugins
   • Owner information complete

5. Present validation report:

   • Summary of marketplace validation
   • Summary of each local plugin validation
   • Overall quality assessment

6. Ask user: "Validation complete. Would you like me to fix any issues, or proceed to testing?"

Output: Marketplace validated and ready for testing

---

Phase 8: Testing & Finalization

Goal: Test marketplace installation and finalize

Actions:

1. Test locally:

   • Show user how to test:

     /plugin marketplace add ./path/to/marketplace
     

   • List marketplace:

     /plugin marketplace list
     

   • Install test plugin:

     /plugin install plugin-name@marketplace-name
     

2. Verification checklist:

   • Marketplace adds successfully
   • All plugins appear in /plugin browser
   • Local plugins install correctly
   • External plugins accessible (if public)

3. Create summary:

   • Mark all tasks complete
   • List what was created:
     • Marketplace name and purpose
     • Number of plugins configured
     • Distribution strategy
     • Key files created
   • Next steps:
     • Push to GitHub/git hosting
     • Share with team
     • Add to project settings

4. Suggest improvements (optional):

   • Additional plugins to consider
   • CI/CD integration opportunities
   • Version management strategies

Output: Complete, validated marketplace ready for distribution

Throughout All Phases

• Use Task tools to track progress at every phase (TaskCreate, TaskUpdate, TaskList)
• Load marketplace-structure skill for schema reference
• Use plugin-validator agent for validation
• Ask for user confirmation at key decision points
• Follow this repository's marketplace.json as reference
• Apply best practices:
  • kebab-case names
  • Complete owner information
  • Version all entries
  • Document all plugins in README
  • ${CLAUDE_PLUGIN_ROOT} for local plugin paths

Key Decision Points (Wait for User)

1. After Phase 1: Confirm marketplace purpose
2. After Phase 2: Approve plugin plan
3. After Phase 3: Confirm metadata
4. After Phase 5: Proceed to distribution setup
5. After Phase 7: Fix issues or proceed

Skills to Load
