marketplace.json must conform to the marketplace schema

Error

Rule Details ​

This rule validates marketplace.json files against the official Claude Code marketplace schema. A valid marketplace.json requires a name, owner (with name), and plugins array. Each plugin entry must have a name and source. The rule checks JSON syntax, schema conformance, and that each plugin entry has the required fields.

Incorrect ​

marketplace.json missing required owner field

json
{
  "name": "my-marketplace",
  "plugins": []
}

Plugin entry missing required source field

json
{
  "name": "my-marketplace",
  "owner": { "name": "Dev Team" },
  "plugins": [
    { "name": "my-plugin" }
  ]
}

Correct ​

Valid marketplace.json with relative path source

json
{
  "name": "my-marketplace",
  "owner": { "name": "Dev Team" },
  "plugins": [
    {
      "name": "my-plugin",
      "source": "./plugins/my-plugin",
      "description": "A useful plugin"
    }
  ]
}

Valid marketplace.json with GitHub source

json
{
  "name": "my-marketplace",
  "owner": { "name": "Dev Team" },
  "plugins": [
    {
      "name": "my-plugin",
      "source": { "source": "github", "repo": "owner/repo" }
    }
  ]
}

How To Fix ​

Ensure marketplace.json has the required fields: name (string), owner (object with name), and plugins (array). Each plugin entry needs name and source. See the official docs.
