@haydenschmittyCapturedClaude Code / Skills

Exact instruction

Identify the target: haydenschmitty's free Claude skill that audits a codebase against 300+ common mistakes (UI/UX, performance, security). Do NOT install it yet.
Research it first — what the skill actually does, who haydenschmitty is, what access it needs to run unattended for hours, and whether it's safe and reputable. Use the Find the Resource search string to locate it.
Present the findings for review, and install ONLY after explicit approval.
Once approved and installed: run it on the codebase to audit across UI/UX, performance, and security; it runs uninterrupted for several hours (e.g. start it before bed and review in the morning).
