SCOPE:

Validating plugin structure and required fields
Testing plugin loading in projects
Verifying knowledge content quality
Checking consistency with patterns
Identifying issues before deployment

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 "platform@violet.io"
[ ] 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

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"
      }
    }
  }
}

Start a new Claude Code session
Verify plugin knowledge is available
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 |

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
