vannifr/nfr-gap-audit
Use when running a systematic, self-directed skill-and-NFR audit on a website/web-app project — discovering skills from Tessl and VoltAgent, identifying non-functional-requirement gaps (performance, accessibility, security, SEO, testing, privacy, i18n, ...), and planning/implementing improvements in small, verified, committed phases. Trigger on "skill audit", "NFR audit", "audit this project for skills/gaps", "what skills am I missing", or before starting a multi-phase quality-improvement effort on a site.
