Tip: --system-prompt-snapshot off renders the system prompt fresh every request while you iterate on it
Claude Code 2.1.267 adds `--system-prompt-snapshot off`, which stops reusing the conversation's recorded system prompt and re-renders it on each request. It exists specifically for iterating on prompt text, since the default snapshot behavior means edits to a system prompt do not take effect mid-conversation. The tradeoff is that it deliberately gives up the prompt-cache prefix stability the rest of the release works to protect, so turn it off again once the prompt settles.
