   Tool `hub_repo_search` accepts unconstrained string input· hub_repo_searchunconstrained input

   The following string parameter(s) have no `maxLength` constraint: `author`, `query`. Unbounded strings let an attacker stuff arbitrary payloads through the tool, including indirect-injection content.

   fix: Add a `maxLength` to each string property, or constrain with an `enum` or `pattern`. Most legitimate tool inputs fit under a few hundred bytes.

   The following string parameter(s) have no `maxLength` constraint: `config`, `split`. Unbounded strings let an attacker stuff arbitrary payloads through the tool, including indirect-injection content.
