FAQPage Schema
How do I create and validate a marketplace.json file for Claude Code plugins?▼

Marketplace.json files organize multiple Claude Code plugins with metadata, dependencies, and source locations. This Skill provides Nushell scripts to initialize a marketplace.json template, validate schema compliance, and check plugin entries, dependencies, and environment variable resolution across local, GitHub, and URL sources in one workflow.

What schema and fields are required in a Claude Code plugin marketplace?▼

A marketplace.json requires marketplace metadata, plugin entries with name, version, license, and dependencies fields, source format specification (local, GitHub, or URL), and strict mode configuration. This Skill documents the complete schema and enforces validation of all required fields and plugin-entry integrity.

Can I detect circular or missing dependencies in my plugin marketplace?▼

Yes. This Skill includes Nushell validation scripts that perform end-to-end dependency checks across all plugin entries, identifying circular dependencies and missing references before you publish your marketplace.

How do I organize multiple Claude Code plugins with different sources in one marketplace?▼

Define each plugin entry with its source format—local paths, GitHub repositories, or URLs—and declare dependencies between plugins. This Skill automates validation of the entire structure and environment-variable path resolution across mixed source types.
