Anthropic Loosens Claude Code Rules After IP Filter Blocks Original Game Projects
From marketbrief.now
AI;DR
Anthropic updated Claude Code to version 2.1.317, allowing the tool to reference existing video game titles when describing mechanics or genre for original projects, while still refusing to recreate existing games. The change follows an Oct. 27 rule that blocked legitimate projects referencing external titles, including public domain works, which Addy Osmani acknowledged was too aggressive.
