| Checked | Without skill | With skill |
|---|---|---|

The instructions your model reads when the skill loads.
This skill has an invalid agent type. Agent must be a built-in (Explore, Plan, general-purpose) or a custom kebab-case name. Invalid_Agent is rejected because underscores are not allowed; use hyphens for kebab-case format.
