Replit Agent Stuck or Looping? Prompts That Unstick It
Quick answer: Is your Replit Agent stuck in a fix-break loop or repeating the same error? Use these practical steps and copy-paste prompts to get it moving again.
The symptom
The Agent keeps "fixing" the same error, undoes its own changes, or repeats steps without making progress. Often the same stack trace shows up in the Console after every attempt.
Why it happens
- The real error is hidden. The Agent only sees part of the log.
- The task is too big, so the Agent changes many files at once.
- The context is full of failed attempts that steer it the wrong way.
- An environment problem (a missing secret, port, or package) is being treated as a code bug.
Steps to unstick it
- Stop the loop. Pause the Agent instead of letting it keep spending attempts.
- Roll back. Use Replit's checkpoints/rollback to return to the last working state.
- Get the real error. Run the app yourself, then copy the first error and the full stack trace from the Console.
- Check the environment. Confirm that Secrets exist for every required API key, that the server listens on
0.0.0.0and the expected port, and that dependencies are installed. - Ask a narrow question. Give the Agent one bug at a time.
- Start fresh if needed. A new chat with a clean summary often beats a long, polluted thread.
Copy-paste prompts
Diagnose before changing anything
Do not edit any files yet. Here is the exact error and stack trace: [paste]. Explain the root cause in 3 sentences and list which single file needs to change.
Limit the blast radius
Fix only this error. Change at most one file. Don't refactor, rename, or reinstall packages. Show me the diff before applying.
Break the loop
You have tried the same fix several times. List each approach you tried and why it failed, then propose a different approach.
Check the environment first
Before changing code, verify: the required env vars exist in Secrets, the server binds to 0.0.0.0 on the configured port, and all imported packages are installed. Report what's missing.

FAQ
Does rolling back delete my work? It returns code to that checkpoint, so copy anything you want to keep first. Should I let the Agent keep trying? If it hasn't made progress after two or three attempts, stop and narrow the task.
