PDFs age the day you export them. A short Loom-style walkthrough plus a sandbox URL respects how engineers evaluate tools: they click, they break things, they decide.
What a good demo contains
- One “happy path” under five minutes.
- Explicit scope of what is mocked vs. real API.
- Clear next step: trial, call, or custom build request.
On the marketplace, look for products with embedded video and labeled gallery shots — that’s the same philosophy extended to the card UI.
