validate-marketplace

What problem does it solve?

This skill automates validation of a Claude Code marketplace repository to surface inconsistencies between marketplace.json, individual plugin.json files, SKILL.md declarations, and README catalog entries. It helps maintainers detect missing plugins, version mismatches, orphan entries, inaccurate skill counts, and naming convention violations before publishing or updating the marketplace.

Core Features & Use Cases

• Cross-file consistency checks: Verify each plugin has a marketplace entry and each marketplace entry maps to an actual plugin directory.
• Metadata and documentation validation: Confirm versions match between plugin.json and marketplace.json, ensure SKILL.md frontmatter contains required fields, and validate README catalog completeness and skill counts.
• Use Case: When preparing a marketplace update, run this skill to produce a pass/fail report that pinpoints missing or mismatched entries so maintainers can fix issues before users encounter installation errors.

Quick Start

Run validate-marketplace to scan the repository and produce a validation report listing passes and failures for marketplace.json, plugin.json, SKILL.md frontmatter, naming conventions, and README catalog entries.
