Asked for accessible DSFR accordion markup: the skill pulled the exact official structure (section.fr-accordion > h3.fr-accordion__title > button.fr-accordion__btn[aria-expanded][aria-controls] + div.fr-collapse) straight from its bundled code.md and accessibilite.md, which a from-memory answer has no way to reproduce correctly; the catch is the README's own manual git-clone instructions are stale and would install a broken (2-levels-too-deep, undiscoverable) skill folder.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 5/5
- Output vs. baseline 9/10
- Docs & honesty 2/5
What Design System Francais (DSFR) does
Bundles synced documentation (index/accessibilite/code/design.md + working HTML examples) for 23 DSFR components used on French government websites, so Claude can answer with the exact fr-* class names, ARIA pattern and RGAA 4.1 accessibility requirements instead of guessing. Triggers when the user asks to implement a DSFR component, needs RGAA guidance, or is building a French government site.
