How do I keep my local JSON schemas in sync with the anthropics marketplace?▼

To keep local JSON schemas in sync, this Skill re-analyzes the official anthropics/claude-plugins-official marketplace. It extracts top-level keys, source formats, and category values, then automatically updates your local marketplace.json and plugin.json schemas to ensure compatibility.

What does schema synchronization do when the marketplace changes?▼

Schema synchronization identifies discrepancies between the official repository and local schemas. It reports new fields, changed formats, and updated values, then modifies your local marketplace.schema.json and plugin.schema.json files to reflect the official structure.

How do I validate my local plugin manifests against the latest schemas?▼

To validate local plugin manifests, this Skill fetches the latest marketplace.json, updates your local JSON schemas, and then verifies the integrity of both the updated schemas and your local plugin.json files to prevent validation errors.

Can I use this to find missing fields in my plugin.json manifest?▼

Yes, you can use this to find missing fields. It compares your local plugin.json against the official anthropics marketplace, reporting differences in top-level keys, lspServer shapes, tag values, and author shapes to ensure your manifest is complete.
