--- name: stitch-react-native version: "1.2" last_updated: 2026-06-15 tags: [stitch, react-native, mobile, components, frontend] description: "Convert Stitch HTML designs into React Native screens using native primitives, StyleSheet rules, and mobile platform checks." license: Apache-2.0 --- # Stitch React Native This skill is a catalog-normalized import from `https://github.com/google-labs-code/stitch-skills` at commit `1544aa4a3be93e7515b0c27d32722f7ca5a2f691`, source path `plugins/stitch-build/skills/react-native`. The upstream control file was corrected for this workspace: the verified Stitch MCP surface here is design-system oriented, so screen lookup, screen generation, and screen editing tools must be used only when the current host explicitly exposes them. ## When to Use This Skill - Use when Stitch web designs should become React Native screens or components. - The task involves Google Stitch project IDs, `.stitch/` artifacts, DESIGN.md files, Stitch exports, or Stitch-specific validation. - The broader `stitch-design` router points here as the narrowest workflow. ## Workflow 1. Start from exported Stitch HTML and a screenshot, using host-listed screen tools only when present. 2. Map web elements to React Native primitives and wrap visible text in `Text`. 3. Translate CSS into `StyleSheet.create()` with native values. 4. Replace hover, fixed positioning, browser-only CSS, and DOM events with native patterns. 5. Use SafeAreaView, useWindowDimensions, Platform.select, FlatList, and SectionList where appropriate. 6. Validate syntax with the bundled validator when dependencies are installed. ## Local Assets - `examples/`, `resources/`, `references/`, or `reference/` are upstream support material when present. Treat `SKILL.md` as the source of truth if a support file mentions an unavailable MCP tool. - `scripts/` are optional helpers. On Windows, prefer PowerShell or Node equivalents unless Git Bash or WSL is actually available. - Keep generated `.stitch/` files out of commits unless the user explicitly wants them as durable examples. ## Corrected Stitch MCP Surface Verified in this workspace on 2026-06-15: `create_project`, `upload_design_md`, `create_design_system_from_design_md`, `list_design_systems`, and `apply_design_system`. Do not claim `list_projects`, `list_screens`, `get_project`, `get_screen`, `generate_screen_from_text`, `edit_screens`, or `generate_variants` were used unless the current host exposes those exact tools in the active tool list. ## Anti-Patterns - Claiming a Stitch screen-generation, screen-editing, or screen-retrieval MCP call succeeded when the active host does not expose that tool. - Uploading files, screenshots, HTML, markdown, or design assets to Stitch without user-approved destination and artifact details. - Reading, printing, storing, or committing Stitch API keys, MCP config secrets, cookies, or credential-bearing files. - Treating generated design or code as final without local render, syntax, or artifact verification. - Collapsing this workflow into a broader frontend/design skill when Stitch-specific files, project IDs, or design-system assets matter. ## Verification Protocol Before claiming this skill was applied successfully: 1. Pass/fail: No DOM tags or web event names remain. 2. Pass/fail: Text, images, lists, and press interactions use native primitives. 3. Pass/fail: iOS and Android shadow/safe-area differences are handled or scoped out. 4. Pass/fail: The result was checked with local React Native tooling or blocker evidence. 5. Pressure-test scenario: Repeat the workflow with Stitch MCP screen tools unavailable and confirm the fallback path remains honest and actionable. 6. Success metric: The user can identify the exact artifact, project/design-system target, and verification evidence without relying on unstated MCP behavior. ## Cross-Client Portability This skill is written to stay usable across GitHub Copilot, Claude Code, Codex, and Gemini CLI. - GitHub Copilot: keep the folder in a Copilot-visible skill or plugin path, or wrap the workflow as project instructions if the host does not support portable skill folders directly. - Claude Code: keep the folder in a local skills directory or a compatible plugin or marketplace source. - Codex: install or sync the folder into `$CODEX_HOME/skills/` and restart Codex after major changes. - Gemini CLI: this repository generates a project command named `/skills:stitch-react-native` from this skill. Rebuild commands with `python scripts/export-gemini-skill.py stitch-react-native` and then run `/commands reload` inside Gemini CLI. ## MCP Availability And Fallback Preferred MCP Server: Stitch MCP - Fallback prompt: "Use the Stitch React Native skill without Stitch MCP. Use local HTML/screenshots and manual native mapping when Stitch MCP screen retrieval is unavailable. Show the exact files, commands, manual Stitch UI steps, and verification evidence used before concluding." - Verified Stitch MCP tools in this workspace are design-system/project oriented; use broader screen tools only when the current host exposes them. - Use local scripts, exported HTML/screenshots, the Stitch web UI, and project metadata files as the fallback evidence path. ## Related Skills - [stitch-react-components](../stitch-react-components/SKILL.md): Use when the task also needs this adjacent Stitch workflow. - [frontend-design](../frontend-design/SKILL.md): Use when the task also needs this adjacent Stitch workflow. - [react-development](../react-development/SKILL.md): Use when the task also needs this adjacent Stitch workflow.
