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:
/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:
- Ask only for product/business decisions that cannot be inferred.
- Ask one question at a time.
- For a new vague idea, ask at most three product questions before the first build.
- Never ask normal users to choose technology by default.
- Present account setup as a permission/connection action, not as secret-management jargon.
- Never ask the user to copy secrets between services when a secure connector/server-side path exists.
- Report progress in product terms: build → frontend quality → prepare data → publish → connect domain → verify.
- 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:
Create at : <official provider URL>
Instructions: <minimum useful permission guidance>
Save with : <safe SI-Coder handoff>
Stored in : <protected local store>
Continue : <verification/continuation action>
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:
[rekomendasi]
Next : <one highest-value next step>
Why : <one sentence>
Needs : <prerequisites or "nothing from you yet">
If you want : <what SI-Coder will do next>
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→scskills/sc-build/SKILL.md→sc-buildskills/sc-all/SKILL.md→sc-allskills/sc-fe/SKILL.md→sc-feskills/sc-ui/SKILL.md→sc-uiskills/sc-ux/SKILL.md→sc-uxskills/sc-dx/SKILL.md→sc-dxskills/sc-ax/SKILL.md→sc-axskills/sc-provider/SKILL.md→sc-providerskills/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.
