How to audit agent skills before installing (2026 checklist)

Best Agent Skills covers agent skills for readers comparing real purchase risk — not gallery demos. This page (audit-skills-security-2026) answers the decision behind “How to audit agent skills before installing (2026 checklist)” with a buyer checklist you can finish in one sitting.

Quick rule: Before installing a skill: read SKILL.md, list files in scripts/, verify license and author (Anthropic, Vercel, Trail of Bits first). Never run blind scripts on production repos.

How buyers usually interpret “agent skills”

People landing here usually already shortlisted Anthropics Skills and Static Analysis (Trail of Bits). The open question is renewal, exit, and whether Skill Creator should stay as a control. Nearby interest we track editorially includes agent skills — use it as a prompt, not as proof.

Two traps that still waste money on agent skills

Trap A — auto-update without diff review. Ask for written proof on Anthropics Skills before any annual. If the answer is a slide deck, stop.

Trap B — skill that reads the whole monorepo. Reproduce the failure on Static Analysis (Trail of Bits) with the same workload. If Skill Creator is cleaner on that single test, keep it on the sheet.

Field note (Atlanta)

A solo founder in Atlanta almost prepaid Anthropics Skills after a polished demo. They reran the same job on Static Analysis (Trail of Bits), captured renew price and cancel URL the same day, and kept Skill Creator as a quiet third column. The annual wait saved a quarter of wasted seats.
