Describe the Bug
When I ask Claude Opus 4 to fix a specific part of my code (e.g. “Correct the off‑by‑one error in this loop”), it ignores the scope of my request, repeats the same suggestions in a loop, and never delivers a working solution—even after multiple prompts. I haven’t been charged yet because I blocked the transaction, but I’d like to resolve this before any payment goes through.
Steps to Reproduce
Open a new session in Cursor.ai using Claude Opus 4.
Paste a code snippet and prompt: “Please fix only the off‑by‑one error in this loop.”
Observe that the model:
Echoes identical text verbatim across responses
Adds unrelated commentary outside the requested scope
Never converges on a corrected code snippet
Sign out, create a fresh Cursor account, subscribe again, and repeat steps 1–3.
Expected Behavior
The model applies the requested change once and returns corrected code.
It respects “inside‑scope” instructions without redundant repetition.
The session ends after delivering a valid solution—no endless loops.
