 We're not pedantic about formatting (Prettier on save is fine), but two rules are non-negotiable because they show up in the prompt stack and the user-facing API:
 
 1. **Single quotes in JS/TS.** Strings are single-quoted unless escaping makes them ugly. The codebase is already consistent — please match.
-2. **Comments in English.** Even if the PR is translating something into 中文, code comments stay in English so we can keep one set of greppable references.

 The **Skill** dropdown groups by mode (Prototype / Deck / Template / Design system) and shows the default skill per mode with a `· default` suffix. Bundled skills:
 
 - **Prototype** — `web-prototype` (generic), `saas-landing`, `dashboard`, `pricing-page`, `docs-page`, `blog-post`, `mobile-app`.
-- **Deck / PPT** — `simple-deck` (single-file horizontal swipe) and `magazine-web-ppt` (the `guizang-ppt` bundle from [`op7418/guizang-ppt-skill`](https://github.com/op7418/guizang-ppt-skill) — default for deck mode, ships its own assets/template + 4 references). Skills with side files get an automatic "Skill root (absolute)" preamble so the agent can resolve `assets/template.html` and `references/*.md` against the real on-disk path instead of its CWD.

 Pair a skill with a design system and a single prompt produces a layout-appropriate prototype or deck in the chosen visual language.
