A Claude Code plugin follows this structure:

├── .claude-plugin/
│ └── plugin.json # Plugin metadata
├── agents/ # Optional: Specialized agents
│ └── agent-name.md
├── skills/ # Optional: Reusable skills
│ └── skill-name.md
├── hooks/ # Optional: Lifecycle hooks
│ ├── hooks.json # Hook configuration
│ └── hook-name.md # Hook implementation
└── README.md # Plugin documentation
Required fields in .claude-plugin/plugin.json:
{
"name": "plugin-name",
"displayName": "Human Readable Name",
"description": "Brief description of plugin purpose",
"version": "1.0.0",
"category": "discipline|tooling|domain|other"
}
Categories:
discipline: Software engineering practices (TDD, code review, etc.)tooling: Development tools and workflowsdomain: Domain-specific knowledge (e.g., React, Python)other: Everything elseAll agents MUST include valid YAML frontmatter:
---

Skills can be invoked from agents or used standalone.
Define hooks in hooks/hooks.json:
{
"hooks": [
{
"name": "hook-name",
"path": "hook-name.md",
"triggerEvent": "Stop|SubagentStop|Start",
"matchQuery": ".*"
}
]
}
Trigger events:
Stop: Before main agent completesSubagentStop: Before subagent completesStart: When agent/subagent startsmatchQuery: Regex to match user queries (use ".*" for all)|| exit 2 to fail hard on errorsQuality enforcement (Stop/SubagentStop):
# Ensure Quality
Before finishing:
1. Run validation tools
2. Verify all checks pass
3. Show proof of validation
4. Do NOT complete if checks fail
Setup validation (Start):
# Verify Environment
Before starting:
1. Check required dependencies
2. Validate configuration
3. Confirm setup complete
All plugins MUST pass claudelint validation:
uvx --from 'git+https://github.com/stbenjam/claudelint' claudelint .
Common claudelint checks:
All markdown files MUST pass markdownlint:
npx -y markdownlint-cli2 --fix .
Use .markdownlint.json for configuration:
{
"default": true,
"MD013": false,
"MD033": false,
"MD041": false
}
Common rules:
ALWAYS run both validators before completing work:
.claude/plugins/Before releasing a plugin:
Add plugin to .claude-plugin/marketplace.json:
{
"plugins": [
"path/to/plugin-name",
"other/plugin"
]
}
Use relative paths from the marketplace file location.
Ensure your plugin is discoverable:

Common issues and solutions:
This plugin includes quality enforcement hooks that run automatically:
ensure-plugin-quality: Runs on main agent completionensure-subagent-plugin-quality: Runs on subagent completionThese hooks ensure:
CRITICAL: Never complete work if validation fails. Fix errors first.
