# SI-Coder umbrella

The canonical user-facing skill is **`sc`**. Invocation syntax is surface-specific: ChatGPT Web uses automatic selection or `@sc`, while slash-capable local hosts can expose `/sc` and focused skills such as `/sc-fe`.

## Language

Keep durable skill instructions and documentation in English. **Reply in the user's language** unless the user asks for another language.

## Route by user goal

| User intent | Internal skill |
|---|---|
| New app, business idea, or vague website request | `sc-build` |
| Substantial frontend improvement or combined UI+UX+DX+AX | `sc-fe` |
| Focused visual interface/design-system/anti-slop work | `sc-ui` |
| Focused usability/accessibility/interaction work | `sc-ux` |
| Focused frontend developer-experience work | `sc-dx` |
| Focused Agent Experience/tool/project ergonomics work | `sc-ax` |
| Existing app that needs to be published or connected to a domain | `sc-all` |
| Account, permission, API-key, or credential lifecycle | `sc-provider` |
| Install SI-Coder into another agent runtime | `sc-install` |
| Explicit advanced provider operation | matching `sc-*` provider skill |

Do not make a non-technical user choose a sub-skill, framework, database, hosting provider, deployment method, or quality axis. The main `sc` skill owns routing.

## Frontend profiles

`sc-fe` preserves coherent existing design DNA by default. It also accepts principle presets/profile flags when the host passes arguments, for example:

App Store Kit

allexp1/app-store-kit

Takes an iOS/iPadOS app from code to the App Store and keeps it updated, hands-off. It checks the code against Apple's current review rules, writes the product page in every language the owner wants, makes screenshots per language and device, archives and uploads the build, and fills App Store Connect itself through the official API (texts, languages, screenshots, age rating, accessibility, review details, build, submit, release), using Chrome only where the API can't reach. It works step by step and stops for the person only where Apple requires them (sign-in, agreements, tax, banking, DSA):
