Validate Plugin

Validate that a plugin follows the correct Claude Code plugin format.

When to use

After creating or modifying a plugin, run validation to catch structural issues before publishing.

Checks performed

1. Directory structure — .claude-plugin/plugin.json exists at plugin root
2. plugin.json schema — required fields present (name, description, version)
3. Skills — each skill in plugin.json.skills has a matching skills/<name>/SKILL.md
4. Commands — each command in plugin.json.commands has a matching commands/<name>.md
5. Agents — each agent in plugin.json.agents has a matching agents/<name>.md
6. SKILL.md frontmatter — each skill has name, description, and allowed-tools
7. Agent frontmatter — each agent has name, description, and model
8. No files in wrong locations — skills/commands/agents not inside .claude-plugin/
9. MCP tool references — tools in allowed-tools are valid mcp__claude-flow__* identifiers
