A developer used Claude Cowork to inspect an API site, explain the trouble, and make direct code fixes after another agent kept making things worse.

What they did
They ran Claude Cowork on a laptop and let it work inside the project much like a remote IT helper. When Replit’s agent kept mangling simple updates, they switched to Claude Cowork and had it dig into the site’s code and correct the problems by hand.
How it went
The API website ended up fixed after the repeated failures with the other agent. The post does not spell out the exact edits, timing, or technical limits, so the repair process itself is not fully documented.
Tips
For this kind of task, ask the agent to explain the issue in plain language before it changes anything. Keep a checkpoint before any action that cannot be rolled back, and review the edits as they go.

Try it yourself with Claude Cowork

I need help with my API site at [project folder or URL]. First, inspect the code and tell me what is most likely causing [specific error or broken behavior] in simple terms. Then propose the smallest safe fix and wait for my approval before editing files. After you make changes, show me exactly what you changed and ask me to confirm the site works before you do anything irreversible, including deleting files, sending data, or submitting changes.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
