Can I manually edit the generated marketplace.json file?

No, marketplace.json is regenerated during the sync process. You should always perform edits in marketplace.extended.json and let the Marketplace Manager skill sync the changes.

What is the difference between marketplace.extended.json and marketplace.json?

The extended file is the manual source of truth containing full metadata like featured status and pricing, while the standard file is a sanitized, CLI-compatible subset generated automatically for distribution.

How does the skill ensure catalog integrity?

It performs multiple checks including JSON syntax validation, duplicate name detection, source path existence verification, and ensuring all required metadata fields are present.

What happens if a sync fails due to a schema error?

The skill identifies the specific error—such as a missing comma or invalid field type—using JQ validation and provides a report so you can fix the source file before retrying.
