Unclear It is not clear what the rewritten prompt now says or how it changes Claude's behaviour.

What

The system prompt is the set of instructions Claude Code gives Claude before you type anything. The system prompt used in Claude Code's agent-claude setup has been rewritten. It still opens with "You are an interactive agent that helps users with software engineering tasks."

Why

These are Claude's own instructions, so changing them changes how Claude behaves in that setup.
