DOP 359: Demos in the Age of AI Agents

#359: When was the last time you sat through a 30-minute product demo and walked away actually knowing anything? You would learn more from five minutes hands-on than an hour of watching someone else drive.

Now you have help. An agent can watch the 30-minute video, play in the sandbox, read every page of the docs, and come back before you finish your coffee with a verdict - tried it, does not work, next. The agent is the new tire kicker. So if you are a vendor, an open source maintainer, or the person building the internal app nobody outside the building ever sees, the demo you have been giving is aimed at a buyer who already left the room.

Your job now is to make life easier for agents. An MCP server, a CLI, skills, an AGENTS.md file, not blocking your own site with Cloudflare when someone’s agent tries to read your pricing. Everything that makes a product easy for an agent would have made it easier for a human all along. We just never bothered, because we had months to burn. Now the clock runs in minutes and every corner we cut is suddenly on fire.

Three kinds of demo, three different answers. The vendor sales demo is off-putting before it starts - if a website says book a call to try it, Viktor is already gone. Open source barely needs a demo at all: a good README, a quick start, an AGENTS.md, and the agent assembles a demo tailored to your stack, your database, your questions, instead of some generic happy path. Internal is where it gets good, and it might be the one that matters most since exactly zero apps ship without customization. Viktor’s bar: stop showing me plans, show me the thing running. Sit the stakeholder down and build it live while you talk. Three days to a prototype instead of 300 pages of PRD.

Sandboxes first, demos second - if you cannot spin up a sandbox, you did not build it right. And demo the failure modes, not the happy path, because resiliency is the real selling point now. Disks still fill up. No amount of AI magic empties them for you.
