📝 Walkthrough

Walkthrough

The skill-creator entry in the skills map within skills.json is updated to point to a new GitHub ref. The target string format is also adjusted by removing the .git suffix. All other entries (rstack-skill-evaluator, pr-creator) and the surrounding structure, including the selfSkill flag, remain unchanged.

In `@skills.json`:
- Line 6: The skill-creator dependency path reference in skills.json is
incorrect. The path /skills/skill-creator does not exist in the
anthropics/skills repository at commit 57546260929473d4e0d1c1bb75297be2fdfa1949.
Verify the actual directory structure in the anthropics/skills repository at
that commit to determine the correct path where skill-creator is located, then
update the path value in the skill-creator entry to reference the correct
location.
