Top fixes — ranked by score impact

✗ VERIFY-01 Evals or tests present
SKILL.md:1the skill works → no evals/, tests/, or verification section found
No way to prove the skill does what it claims.
Fix Add an evals/ folder (test prompts + expected outcomes) and a '## Verify' step in the body.
⚠ SAFETY-03 No destructive auto-invocation
SKILL.md:25auto-invocable (no disable-model-invocation) → performs a destructive action ("Delete")
Skill appears to "Delete" but the model can auto-invoke it — a destructive action could fire without the user asking.
Delete
Fix If this action is destructive/irreversible, set `disable-model-invocation: true` so it only runs when explicitly invoked.
