This table is not valid Markdown because it starts each row with double pipes (||). Use single | delimiters so it renders correctly. Also consider making the skill entry a link (e.g., to skills/sponsor-finder/SKILL.md) and using the skill name instead of a generic SKILL.md label to improve readability.
