what is this for? I couldn't find it in the skill spec.

[thisisatharva-rh]

so cursor (my platform right now) requires these. description is used to decide whether to include the skill and globs are patterns - when relevant, cursor will pull this skill into context. i want to make this skill agnostic to dev editors; planned as future work
