What happens if there is a schema error in my catalog?

The Marketplace Manager automatically runs integrity checks and validation scripts (like jq syntax checks) to identify missing commas, invalid field types, or duplicate plugin names.

Can I manually edit the marketplace.json file?

No, marketplace.json is auto-generated. You should always edit marketplace.extended.json and use the Marketplace Manager to sync the changes.

What is the two-catalog system managed by this skill?

The system uses marketplace.extended.json as the source of truth containing full metadata, while marketplace.json is an auto-generated, sanitized subset used for CLI performance.

How does the skill handle new plugin additions?

When you mention adding a plugin, the skill reads the plugin's metadata, creates the entry in the extended catalog, runs the sync script, and validates the output automatically.
