Opus 5.5 safeguards block a benign arXiv paper implementation request, flagged as cyber

Dimitris Papail shares a screenshot showing Opus 5.5 blocking a benign request to read an arXiv paper and implement a toy version of it — flagged under category "cyber," with the UI suggesting switching to Opus 4.8. The block message admits Opus 5.5's stronger safeguards can incorrectly flag non-cybersecurity work and that fixes are in progress. Papail stresses the issue isn't "write my paper" — routine methodological questions are being blocked, highlighting growing frustration with Anthropic's aggressive guardrails.
