Top fixes — ranked by score impact

✗ STRUCT-05 Supporting-file references resolve
SKILL.md:15references `references/detailed-guide.md` → no such file or directory in the skill
Reference to `references/detailed-guide.md` does not resolve to a file in the skill directory.
references/detailed-guide.md
Fix Add the missing file(s), fix the path, or remove the dead reference.
✗ 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:30auto-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.
⚠ TRIGGER-03 Invocation cues in the description
SKILL.md:1description will match user requests → no explicit cue ('use when …', 'triggers on …', quoted user phrases) found
Pure what-it-does prose — the model has to guess when to invoke it.
AI-powered presentation generation via the 2slides API — create slides from t…
Fix State the trigger explicitly: 'Use when the user says "…", "…", or wants to …'.
