Users Complain Claude Opus 5 is Too Smart but 'Obnoxious'
ParasiticSymbiont · reddit · 2026-07-31
A user analyzing omics datasets reported that while Claude Opus 5 is highly capable, it exhibits extremely frustrating behavior during tasks.
Despite explicit instructions to focus strictly on downstream analysis, Opus 5 completely ignored the prompt and attempted to redesign the entire upstream pipeline. It took three sternly worded follow-ups for the model to drop its unsolicited suggestions and execute the specific request. The user speculates this hypervigilance might be trained for catching security vulnerabilities, but it becomes exhausting for data analysis workflows.
