Validation Process

Step 1: Structure Validation

Check directory structure:

plugins/{category}-{name}/
├── .claude-plugin/
│   └── plugin.json       # Required
└── knowledge/
    └── *.md              # At least one file

Checklist:

• Directory name matches {category}-{name} pattern
• .claude-plugin/ directory exists
• plugin.json file exists
• knowledge/ directory exists
• At least one .md file in knowledge/

Step 2: plugin.json Validation

Required fields:

{
  "name": "string (must match directory name)",
  "version": "string (semver format)",
  "description": "string (1-2 sentences)",
  "author": {
    "name": "string",
    "email": "string (valid email)"
  },
  "knowledge": ["./knowledge/"]
}

Checklist:

• name matches directory name exactly
• version follows semver (e.g., "1.0.0")
• description is present and concise
• author.name is "Violet Platform Team"
• author.email is "[e-mail]"
• knowledge array includes "./knowledge/"

Step 3: Content Validation

Check knowledge files for category-specific requirements:

Agent plugins must have:

• Role section
• System Prompt section
• Scope definition
• Process/workflow steps
• Output format
• Trigger conditions
• Customization guidance

Workflow plugins must have:

• Numbered phases
• Trigger for each phase
• Actions for each phase
• Outputs for each phase

Skill plugins must have:

• Core principles
• Patterns with examples
• Anti-patterns

Domain plugins must have:

• Overview
• Data models
• Key workflows

Platform plugins must have:

• Overview
• API patterns
• Authentication info
• Rate limiting

Stack plugins must have:

• Stack overview
• Project structure
• Code patterns with examples

Step 4: Marketplace Entry Validation

Check .claude-plugin/marketplace.json:

• Plugin has entry in marketplace
• Entry path matches actual plugin path
• Description matches plugin.json description

---

Testing Process

Load Test

1. Enable plugin in a test project's .claude/settings.json:

{
  "enabledPlugins": {
    "{plugin-name}@violet": true
  },
  "extraKnownMarketplaces": {
    "violet": {
      "source": {
        "source": "github",
        "repo": "violetio/violet-ai-plugins"
      }
    }
  }
}

2. Start a new Claude Code session
3. Verify plugin knowledge is available
4. Test that Claude responds appropriately to triggers

Behavior Test

For agents:

• Ask Claude to act as the agent role
• Verify it follows the system prompt
• Check output matches specified format

For workflows:

• Walk through each phase
• Verify triggers work correctly
• Check outputs are produced

Common Issues

Structure Issues

Issue	Fix
Missing plugin.json	Create with required fields
Wrong directory name	Rename to match {category}-{name}
Empty knowledge/	Add at least one .md file
Name mismatch	plugin.json name must match directory

Content Issues

Issue	Fix
Missing required sections	Add sections per category
No examples	Add CORRECT/WRONG code examples
Too vague	Make content specific and actionable
No anti-patterns	Add what NOT to do

Loading Issues

Issue	Fix
Plugin not loading	Check settings.json format
Knowledge not available	Verify knowledge path in plugin.json
Wrong marketplace	Check extraKnownMarketplaces config

---

Quality Gates

A plugin is ready for deployment when:

Required:

• All structure validations pass
• All plugin.json validations pass
• All content validations for category pass
• Marketplace entry exists
• Load test successful

Recommended:

• Behavior test completed
• Reviewed by another team member
• README updated with plugin
