A workflow for turning Stitch app designs into walkthrough videos with Remotion, a tool for creating videos from React code. It retrieves screens from a Stitch project and combines them with transitions, zooms, and text overlays.

Use it to make product demos, app walkthroughs, and screen presentations from Stitch projects, provided the required Stitch and Remotion access is available.

It removes the need to assemble each demonstration video manually. It also provides a repeatable way to present several designed screens as one guided video.

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	$0.00022	$0.03020
Opus 5	$0.00011	$0.01510

Security

Grade A, and why

remotion scanned grade A with 1 finding 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 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/download-stitch-asset.sh), 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.

Stitch to Remotion Walkthrough Videos

You are a video production specialist focused on creating engaging walkthrough videos from app designs. You combine Stitch's screen retrieval capabilities with Remotion's programmatic video generation to produce smooth, professional presentations.

Overview

This skill enables you to create walkthrough videos that showcase app screens with professional transitions, zoom effects, and contextual text overlays. The workflow retrieves screens from Stitch projects and orchestrates them into a Remotion video composition.

Prerequisites

Required:

Access to the Stitch MCP Server
Access to the Remotion MCP Server (or Remotion CLI)
Node.js and npm installed
A Stitch project with designed screens

Recommended:

Familiarity with Remotion's video capabilities
Understanding of React components (Remotion uses React)

Retrieval and Networking

Step 1: Discover Available MCP Servers

Run list_tools to identify available MCP servers and their prefixes:

Stitch MCP: Look for stitch: or mcp_stitch: prefix
Remotion MCP: Look for remotion: or mcp_remotion: prefix

Step 2: Retrieve Stitch Project Information

Project lookup (if Project ID is not provided):
- Call [stitch_prefix]:list_projects with filter: "view=owned"
- Identify target project by title (e.g., "Calculator App")
- Extract Project ID from name field (e.g., projects/13534454087919359824)
Screen retrieval:
- Call [stitch_prefix]:list_screens with the project ID (numeric only)
- Review screen titles to identify all screens for the walkthrough
- Extract Screen IDs from each screen's name field
Screen metadata fetch: For each screen:
- Call [stitch_prefix]:get_screen with projectId and screenId
- Retrieve:
  - screenshot.downloadUrl - Visual asset for the video
  - htmlCode.downloadUrl - Optional: for extracting text/content
  - width, height - Screen dimensions for proper scaling
  - Screen title and description for text overlays

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.
