Anthropic engineer: crank Claude's effort setting for risky code, dial it down for routine tasks

every · x · 2026-09-25

Every highlights advice from Anthropic's trq212 on Claude's effort setting: raising it gives the model more budget to think, test, and verify. For tasks like an HTML sanitizer—where code can fail in many ways—extra checking is worth the tokens. For coding tasks the model already handles reliably, low or medium effort suffices.
