# Si Coder > SI-Coder umbrella skill. Build, improve, and publish web apps from plain-language goals for non-technical users. Route through sc, sc-build, sc-fe, sc-all, sc-provider, or focused UI/UX/DX/AX/provider skills while keeping technical choices and secrets behind a safe abstraction layer. - Skill: `rahmanef63/si-coder` (Agent Skill, multi-file: 13 files) - Install (CLI): `npx skillmds@latest add rahmanef63/si-coder` - Raw SKILL.md: https://api.skillmd.com/api/skills/rahmanef63/si-coder/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: rahmanef63 (https://skillmd.com/u/rahmanef63) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/rahmanef63/si-coder --- # 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: ```text /sc-fe --apple improve settings /sc-fe --workbench audit the desktop shell /sc-fe --profile baton-desktop refine the inspector /sc-fe --save-profile baton-desktop ``` Built-in named reference presets include `apple`, `workbench`, `linear`, `notion`, `vercel`, `material`, `editorial`, and `terminal`. They are ergonomic/design references only; never copy proprietary assets or pixel-clone another product. Explicit scope exclusions are hard locks across all frontend work. ## Non-technical default UX Lead with the outcome and hide the plumbing. A valid request can be: > `Create a booking app for my salon and put it on my domain.` Normally SI-Coder should choose the stack, data service, hosting route, repository strategy, deployment method, frontend quality route, and domain mechanics automatically. Rules: 1. Ask only for product/business decisions that cannot be inferred. 2. Ask one question at a time. 3. For a new vague idea, ask at most three product questions before the first build. 4. Never ask normal users to choose technology by default. 5. Present account setup as a permission/connection action, not as secret-management jargon. 6. Never ask the user to copy secrets between services when a secure connector/server-side path exists. 7. Report progress in product terms: build → frontend quality → prepare data → publish → connect domain → verify. 8. Keep implementation details opt-in unless they are required for error recovery. ## Product discovery Use `sc.product.interview` when available to enforce the discovery limit. Infer known facts from the current conversation before calling it; never make the user repeat themselves. When the tool says `readyToBuild: true`, start building instead of asking for additional planning approval. ## Publishing Use the `sc-all` skill for the runtime-first publish flow. `sc-all` delegates user-facing frontend quality to `sc-fe` before final verification when applicable. - Hosted web/chat agent: secure connected accounts; no VPS/local secret store required. - Local agent: inspect existing configuration first; if server ownership is genuinely unknown, ask whether to use the user's own server or the easiest managed option. The user-facing response should prefer the tool's `userPlan` field. Route/provider diagnostics are advanced details. ## Safe access handoff Never ask for a raw password, API key, token, or deploy key in chat or tool JSON. When local access is required, always provide: ```text Create at : Instructions: Save with : Stored in : Continue : ``` Hosted agents should prefer the secure connection URL returned by the connector. ## Completion A publish is not complete until the public app, domain, HTTPS, core user flow, and applicable frontend quality/interaction checks are verified. After a meaningful milestone, provide exactly one stable next-step block: ```text [rekomendasi] Next : Why : Needs : If you want : ``` Keep the literal `[rekomendasi]` marker, but write the block content in the user's language. ## Portability The `skills/` directory is the Agent Skills SSOT. A portable skill's canonical source is a directory containing `SKILL.md`. For distribution, SI-Coder also builds `.skill` ZIP packages from that source; never hand-edit the generated package. Important skill identities: - `skills/sc/SKILL.md` → `sc` - `skills/sc-build/SKILL.md` → `sc-build` - `skills/sc-all/SKILL.md` → `sc-all` - `skills/sc-fe/SKILL.md` → `sc-fe` - `skills/sc-ui/SKILL.md` → `sc-ui` - `skills/sc-ux/SKILL.md` → `sc-ux` - `skills/sc-dx/SKILL.md` → `sc-dx` - `skills/sc-ax/SKILL.md` → `sc-ax` - `skills/sc-provider/SKILL.md` → `sc-provider` - `skills/sc-install/SKILL.md` → `sc-install` Invocation is surface-specific: Claude Code supports slash commands; ChatGPT Web currently documents automatic skill use and explicit skill/plugin selection; Codex uses its current skill-selection/invocation UX. Packaging as `.skill` does not create a custom ChatGPT Web slash command.
