Figure out why the live app is broken
“It works on my laptop but production is slow, crashing or throwing alerts.”
An agent that can read logs, metrics and config is a fast first responder. Let it investigate and propose; a human approves rollbacks and fixes.
Fix it yourself in 3 steps
- Gather what you have: the error or alert, when it started, and what changed recently (deploys, config).
- Give the agent read-only access to logs and metrics and ask for ranked root-cause guesses with evidence.
- Pick the most likely cause, have it propose the smallest fix or rollback, and you run it.
Copy this prompt
Production issue: [symptom], started around [time]. Recent changes: [deploys/config]. Using read-only access to logs and metrics, list the top 3 likely causes, each with the evidence you found and how to confirm it. Propose the smallest fix or rollback for the top one. Don't change anything in production — stop and wait for my approval.
Fill in the [brackets]. Each prompt says when the AI should stop, so it doesn't wander off.
