stitch::code-to-design

Convert frontend code (Vite, React, Angular, Vue, etc.) to a Stitch Design by chaining static HTML extraction, design system extraction, and file upload. **ALWAYS** use this skill when the user's intent is to move existing web apps or React/Angular/Vue components into Stitch (e.g., requests to "save", "migrate", or "upload"). You must use this skill even for simple "save" operations, as it is the only way to ensure the design system is extracted and assets are properly linked.

Code to Design

Transform your existing frontend code (React + Vite, Next.js, Angular, Vue, etc.) into a Stitch Design so you can iterate and improve it using Stitch.

This skill orchestrates three other skills in sequence:

extract-static-html: Extract a single self-contained HTML file from your build output or running dev server (e.g., Vite dev server or Angular CLI ng serve).
extract-design-md: Analyze the source code (including Angular angular.json, external .html templates, theme files, and components) to create a design system (DESIGN.md).
upload-to-stitch: Upload that HTML file and the design system to your Stitch project.

Workflow

Follow these steps to convert your existing code.

Prerequisites

A running local dev server (e.g. npm run dev, ng serve) OR a built web application directory containing index.html and assets.
Target Stitch projectId (use list_projects if unknown).

Steps

1. Extract Self-Contained HTML

Delegate to the extract-static-html skill to generate a standalone HTML file. Read skills/extract-static-html/SKILL.md for detailed instructions and script usage.

Expected output: A single file like /path/to/extracted/standalone.html.

2. Verify HTML (Optional — User-Driven)

After extraction, inform the user of the output file path so they can manually verify in a browser if desired. Do not block on verification — proceed directly to Step 3.

If the user reports issues after reviewing, fix them before continuing.

3. Extract Design System (File)

Delegate to the extract-design-md skill to analyze the project's source files (components, stylesheets, theme configs) and produce a design system. Read skills/extract-design-md/SKILL.md for the full analysis workflow.

Write .stitch/DESIGN.md following the extract-design-md skill's output structure.

4. Upload DESIGN.md and Create Design System in Stitch

Delegate to the manage-design-system skill to upload the DESIGN.md and create the design system in Stitch. Read skills/manage-design-system/SKILL.md for the full workflow (upload script usage, create_design_system_from_design_md call, and required schemas). Pass --generated-by 'stitch::code-to-design' when uploading.

5. Upload HTML to Stitch

Use the same upload-to-stitch skill's script to upload the extracted HTML file. Read skills/upload-to-stitch/SKILL.md for detailed instructions and script usage.

You will need:

The path to the standalone HTML file generated in Step 1.
Your Stitch API Key (same key used in Step 4).
The target projectId.
The --generated-by argument set to 'stitch::extract-static-html'.
The --title argument set to the route path of the page (e.g., '/dashboard', '/settings/profile', '/inbox') so that the screen name/title in Stitch clearly identifies its route in the application.
