DEDUPEDWho it is forMaintainer or creator who wants a quick explainer video for a GitHub project without editing footage
The problemExplaining how a repo works takes a written walkthrough most visitors never read.
The outcomeA short explainer video for a repo where the architecture scenes come from diagrams drawn by the skill.
What you need first
- An Agent Skills compatible host such as Claude Code, Codex, Cursor, Qoder, GitHub Copilot, Gemini CLI, Cline, Windsurf or Amp
- Node.js for the npx install command
- A browser to open the generated HTML file
- Optional: a public website URL for brand onboarding
Steps
- Install the video tooling the way the field post describes: claude plugin marketplace add heygen-com/hyperframes
- Run: claude plugin install hyperframes@hyperframes
- Run: npx skills add cathrynlavery/diagram-design
- Ask Claude Code to read the repo README, plan the scenes and draw the diagrams, then render the video.
Prompt for your agent
Make a 45-second explainer video for this GitHub repo: <repo URL>. Read the README, state in one sentence what it does, use diagram-design for the architecture scenes, and tell me which scenes you were least sure about.
Caveat. The video side depends on a separate project (HyperFrames) with its own requirements. The prompt shape comes from a community post, not this README, so expect to adjust it.

More with diagram-design
- Draw an architecture diagram for your README without a design tool Describe your app in plain words and get a clean HTML and SVG diagram to drop into your README.
- Draw the plan before your agent writes the code Ask for a flow or sequence diagram of a proposed change and approve the design first.
- Draw your agent setup: tools, data flows and approval points Diagram which tools your AI agent can call, where data moves and where a human must approve.
- Map an unfamiliar repo's components before you change it Have your agent read a codebase and draw its parts and connections so you can orient before editing.
- Make every diagram match your website's colors and fonts Give the skill your site URL once and every later diagram uses your palette and fonts.
- Redraw an old Mermaid or draw.io diagram in a cleaner style Import an existing Mermaid, draw.io or Excalidraw file and get it back as a polished editorial diagram.
- Add light motion to a diagram that explains steps in order Turn on optional motion so a process diagram reveals its steps one after another.
