Read original source →arstechnica.com

A rule named "tengu_heron_brook" in Claude Code 2.1.314 (released Oct 30) tells Claude to build original or genre games but not recreate a specific existing game, even if renamed. Anthropic engineer Addy Osmani confirmed two sentences were added to Opus 5.5's prompt because using Claude to infringe IP violates usage policy.
