Opus 4.7's terser default style breaks down on complex projects. The fix is a custom output style that restores thorough explanations, plus evals to catch this kind of drift on future model releases.

Anyone else feel like Opus 4.7 got noticeably terser in Claude Code, especially on complex work? Took me weeks to realize it wasn’t me. Anthropic’s release notes confirm response length now calibrates to task complexity. Wrote up the fix I landed on: a custom output style that restores thorough explanations without touching the code-writing instructions. Am I the only one? submitted by /u/pablooliva
