# Web Usability Conformity ## Purpose Use this skill to **reach** and **maintain** web usability and accessibility conformity. Default technical target: **WCAG 2.2 Level A + AA** (same technical content as **ISO/IEC 40500:2025 Edition 2.0**). Also report mapping to **EN 301 549** clause 9, **BITV 2.0**, and **BFSG**. **Honesty bound:** “100% conformity” means every applicable A+AA success criterion has a defined test path and a recorded verdict (`pass` / `fail` / `not applicable` / `needs human confirmation`). It does **not** mean axe-core or HTML validation alone is sufficient. This skill is not a certified BITV-Test and is not legal advice. ## When to use - Audit a URL, local app, or frontend code for WCAG / BITV / BFSG readiness - Fix accessibility and understandability defects, then retest - Add Playwright + DOM regression checks so conformity is maintained - Report which norms are met, partially met, or out of scope ## When not to use - As a substitute for a formal accredited accessibility audit or legal opinion - To enforce gender-inclusive language (Gendern) — see guardrails - To claim AAA conformity unless the user explicitly expands scope - To redesign UX for conversion aesthetics alone (use a UX skill for that) ## Required references Read before judging findings: 1. `references/norms-mapping.md` — WCAG 2.2, ISO/IEC 40500, EN 301 549, BITV 2.0, BFSG 2. `references/sc-matrix.md` — every A+AA success criterion and how to test it 3. `references/understandabil
