Lobotomized Claude Code and it works better (github.com)

A new development has emerged for Claude Code with the introduction of system-prompt overrides specifically designed for Claude Opus 4.7. This update significantly reduces the size of essential interactive prompts, resulting in a model that processes instructions more literally and efficiently. The overhaul leads to a remarkable reduction in character length—approximately 67% smaller for daily operational prompts—which enhances response speed and reduces drifts caused by conflicting always-on rules. These optimizations streamline the coding experience, allowing the model to communicate and execute tasks more effectively. The significance of this update lies in its potential to improve user interactions with the model, making it less prone to errors from “CAPS” triggers and unnecessary complexity in command execution. Key strategies include eliminating convoluted language in prompts and encouraging parallel processing of tasks. The modification ensures that crucial operational rules are upheld without sacrificing performance, directly impacting how developers utilize AI for coding tasks. This initiative reflects a growing trend in the AI/ML community focused on refining model behavior to enhance practical applications, suggesting a promising direction for future advancements.
