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.
skill.md500-line guidance → 533 lines
SKILL.md is 533 lines — over the ~500-line guidance. ~4,773 tokens (rough est.); ~$0.0143 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.
skill.mdeverything inlined in SKILL.md → 529 body lines, 0 supporting files
Large SKILL.md (529 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.
