GPT-5.6 launched and developers immediately hit their usage limits. The fix is not a bigger plan

OpenAI's GPT-5.6 update has caused developers to hit their usage limits, despite claims of improved token efficiency. This is due to stronger models consuming more tokens, often for unnecessary context. To fix this, developers should focus on optimizing their setup and using tools like /checkup to identify waste. Popular skills that help with token and context efficiency include subagent-driven development and context engineering.
