Make your agent play the game before it says done

What you end up with

Speed and real testing are different things: a scripted test can pass while the controls a player uses are broken.

What you get

• A plain-language summary of the workflow
• A fill-in prompt template
• What to watch out for
• A link to the original source

Who it is for

Builders who already use AI agents and want a proven workflow they can copy into their own project.

Works with

Solid chips: the agent is named in this listing's own tools list. Dashed chip: Plain Markdown, so it also pastes into other agents such as Grok Bot, Hermes, OpenClaw or Muse. We list those as compatible by format only, not as tested.

Tools needed

Cost to run: Free with the agent plan you already use.
Time to result: One working session

How it works

1. Read what they did

   Skim the source post linked below, then the summary on this page.

   Expected: You know the setup and the one rule that made it work.

2. Fill in the template

   Copy the prompt and replace every [bracketed] value with your own project details.

   Expected: A prompt that fits your project.

3. Run it once and check

   Run it on a small task first and confirm the result yourself before you trust it on real work.

   Expected: One verified run.

Sample prompt from the pack

Build [game] with [features]. When it runs, play it yourself using the same inputs a player would use (keyboard or touch), not by setting positions in code. Complete [one full round]. Report any control, camera or collision bugs you hit, fix them, and replay before you say done.

# Make your agent play the game before it says done

PaperChase agent use case (free feed entry), version 1.0. Source: [@theSethian](https://x.com/theSethian/status/2110440063821545479), 2026-10-14.

## What they did

On 2026-10-14 @theSethian gave both agents the same prompt: a neon track, an AI opponent, a lap timer, three laps, then drive a full race to prove it works. Claude Code finished in 1 minute 43 seconds using a scripted driver that moved the car through code. Grok Bot took about 16 minutes, played with the game's own controls, found the steering was reversed on its first test, fixed it, and completed all three laps.

## Worth knowing

Speed and real testing are different things: a scripted test can pass while the controls a player uses are broken. Both testers lost to the AI car they wrote. The takeaway line from the post is worth putting in any game prompt.
