What
When the model tries to invoke a built-in CLI command as a skill, it now receives a clear error explaining the distinction.
Details
- Error message: "[name] is a [type] command, not a skill. Ask the user to run /[name] themselves — it cannot be invoked via the [tool] tool."
- Prevents confusion between built-in slash commands and skill invocations
