Pull request overview
Updates the chat prompt “skill” parsing and validation behavior to better align skill identity with its containing folder and to relax header requirements while maintaining model-invocation safety.
Changes:
- Change
getCleanPromptName()forSKILL.md(case-insensitive) to return the parent folder name instead ofSKILL. - Relax skill header validation to allow omitted
name/description, but require a description when certain invocability attributes are set. - Exclude skills without a description from the “model-invocable skills” set used for automatic instructions, and update tests accordingly.
