Plugin Validator

Overview

Validates Claude Code plugin structure, JSON schemas, frontmatter format, security compliance, and marketplace catalog consistency. Runs the same checks as the CI pipeline to catch issues before committing.

Prerequisites

• Read access to the target plugin directory and repository-level .claude-plugin/marketplace.extended.json
• jq installed for JSON validation (jq empty <file>)
• grep and find available on PATH for pattern scanning
• ./scripts/validate-all-plugins.sh available at the repository root

Instructions

1. Identify the target plugin path from context or user request. Default to the current working directory if the path contains a .claude-plugin/ subdirectory.
2. Validate required files exist (see ${CLAUDE_SKILL_DIR}/references/validation-checks.md):
   • .claude-plugin/plugin.json present and valid JSON.
   • README.md present and non-empty.
   • LICENSE file present.
   • At least one component directory exists (commands/, agents/, skills/, hooks/, or mcp/).
3. Validate plugin.json schema:
   • Confirm all required fields: name (kebab-case), version (semver x.y.z), description, author.name, author.email, license, keywords (array, minimum 2).
   • Reject any fields not in the allowed set (name, version, description, author, repository, homepage, license, keywords).
4. Validate frontmatter in all component files:
   • Commands (commands/*.md): require name, description, model (one of sonnet, , ).
