No longer reverse-engineer everything? Anthropic reportedly quietly limits Claude Opus 5.5 reverse-engineering ability
Users report that, after Anthropic's 21 October updates to Claude products, Opus 5.5 began stopping mid-output when asked to reverse-engineer intellectual-property-protected content, and rephrasing did not restore the analysis. Anthropic has not announced a new version of Opus 5.5, and some users note reverse-engineering results were always unstable. This matters because developers who relied on the model for decompilation and game reverse-engineering work now face an unannounced capability change, raising questions about how silently model behaviour can shift.
