Observed in the wild: the agent received access to a cloud computer pointed at one live app. It was instructed to click through core user flows several times a day like a new user, log anything broken or confusing, and draft fix PRs. In the first 48 hours it located a real signup flow bug on a specific untested screen size.

Why it matters
Coding agents are moving from autocomplete to doing whole tasks: reading a codebase, making a plan and changing many files. This case is a concrete example of where that works in practice. It is one of 106 sightings filed under Software Development on Agent Sightings (number 45 by interest), and one of 85 involving Grok Bot.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Grok Bot or any similar agent and adjust the details to your situation.
In this repo, use a bot as a QA intern on a live app. Read relevant code, apply a minimal patch, run available checks, and summarize the diff. Stop before merge or deploy.
The prompt breaks down into 3 steps you can check as the agent works:
- In this repo, use a bot as a QA intern on a live app.
- Read relevant code, apply a minimal patch, run available checks, and summarize the diff.
- Stop before merge or deploy.
Tip: Work on a fresh branch, ask for a plan before edits, and review the diff and test results before merging.
