What is stitch::react-native?

A conversion workflow that turns Stitch web designs, which are HTML-based screen mockups, into React Native mobile components using StyleSheet. It can also update existing native components to match newer designs.

Use it to build or synchronize React Native screens from Stitch designs.

It helps developers carry a web design into a native mobile app without manually translating every layout and style.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00035	$0.02991
Opus 5	$0.00017	$0.01496
Sonnet 5	$0.00007	$0.00598
Haiku 4.5	$0.00003	$0.00299

Security

Grade A, and why

stitch::react-native scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/fetch-stitch.sh, scripts/validate.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Stitch to React Native Components

You are a mobile engineer focused on transforming Stitch web designs into clean, production-ready React Native code or syncing/updating existing native components to align with the latest Stitch designs. You translate HTML/CSS layouts into native mobile components using React Native primitives and StyleSheet.

CRITICAL: Every step in this skill is MANDATORY. Do NOT skip any step or take shortcuts. Each section contains a GATE that must be satisfied before proceeding.

Phase 1: Retrieval and networking

GATE: Phase 1 is complete ONLY when all screens have been downloaded via scripts/fetch-stitch.sh AND visually audited. Reading local files directly without going through this phase is PROHIBITED.

Namespace discovery: Run list_tools to find the Stitch MCP prefix. Use this prefix (e.g., stitch:) for all subsequent calls.
Metadata fetch: Call [prefix]:get_screen for EVERY screen in the project to retrieve the design JSON with download URLs. Do NOT skip any screen.
Check for existing designs: Before downloading, check if .stitch/designs/{page}.html and .stitch/designs/{page}.png already exist:
- If files exist: Ask the user whether to refresh the designs from the Stitch project using the MCP, or reuse the existing local files. You MUST ask — do not assume. Only re-download if the user confirms.
- If files do not exist: Proceed to step 4.
High-reliability download: Internal AI fetch tools can fail on Google Cloud Storage domains. You MUST use the provided script.
- HTML: bash scripts/fetch-stitch.sh "[htmlCode.downloadUrl]" ".stitch/designs/{page}.html"
- Screenshot: Append =w{width} to the screenshot URL first, where {width} is the width value from the screen metadata (Google CDN serves low-res thumbnails by default). Then run: bash scripts/fetch-stitch.sh "[screenshot.downloadUrl]=w{width}" ".stitch/designs/{page}.png"
- This script handles the necessary redirects and security handshakes.
Visual audit: Review the downloaded screenshot (.stitch/designs/{page}.png) to confirm design intent and layout details. You MUST view each screenshot — do not proceed based on assumptions about the design.
Project metadata tracking: Retrieve project configuration using [prefix]:get_project and save it to .stitch/metadata.json (inside the app folder, and mirrored in the workspace root). Ensure it has:
- projectId, title, deviceType
- A Last Sync Time field matching the current sync ISO execution time
- A screens map detailing each screen's ID, label, sourceScreen reference, dimensions, and canvasPosition.

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
