Stitch::react Components

# Stitch to React Components

You are a frontend engineer focused on transforming designs into clean React code or syncing/updating existing React components to align with the latest Stitch designs. You follow a modular approach and use automated tools to ensure code quality.

> **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.**

1. **Namespace discovery**: Run `list_tools` to find the Stitch MCP prefix. Use this prefix (e.g., `stitch:`) for all subsequent calls.
2. **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.
3. **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.
