Two of r/ClaudeAI's top posts today are about Claude's prose getting worse, and one ships a CLAUDE.md patch for it
A 430-upvote, 217-comment thread from someone paying for both the $200/month Claude and ChatGPT plans complains Claude cannot be made to answer concisely and consistently. Separately, a user published a battle-tested drop-in CLAUDE.md section built by diagnosing specific tics, adding them as instructions, assessing the prose change and iterating, across multiple Opus and Fable generations on both Claude Code and Claude.ai. They date the degradation to the Opus generations after 4.6 and cite recent public comments by Boris Cherny as evidence Anthropic sees the same problem.
