Support files under references/, templates/, assets/, and scripts/ are progressive-disclosure data loaded through skill_view(..., file_path=...). They should not be treated as standalone skills during discovery or collision checks. This prevents archived skill packages or support markdown files inside a real skill from shadowing active skills with the same name while still allowing top-level categories named scripts/templates/assets/references. Tests cover: - pruning nested SKILL.md files inside skill support directories - preserving support-named top-level categories - avoiding skill_view collisions from support markdown - keeping archived package SKILL.md files accessible only through file_path
