Top fixes — ranked by score impact

✗ SAFETY-01 No hardcoded secrets

skill.md:167— → matches Connection string with password pattern

Possible hardcoded secret (Connection string with password) — post************************************}@

post************************************}@

Fix Remove the secret from source, rotate it, and reference it via an environment variable instead.

✗ 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:43auto-invocable (no disable-model-invocation) → performs a destructive action ("deploy")

Skill appears to "deploy" but the model can auto-invoke it — a destructive action could fire without the user asking.

deploy

Fix If this action is destructive/irreversible, set `disable-model-invocation: true` so it only runs when explicitly invoked.

⚠ TOKEN-01 Body under line/token budget

skill.md500-line guidance → 525 lines

SKILL.md is 525 lines — over the ~500-line guidance. ~5,726 tokens (rough est.); ~$0.0172 per load at $3/Mtok reference rate.

Fix Move heavy reference material into supporting files and link to them (progressive disclosure), keeping SKILL.md lean.

⚠ TOKEN-02 Progressive disclosure

skill.mdeverything inlined in SKILL.md → 521 body lines, 0 supporting files

Large SKILL.md (521 lines) with no supporting files — all of it loads every time the skill fires.

Fix Move heavy reference material into supporting files and link to them, so the model loads it only when needed.
