This two-word prompt keeps Claude Code from rushing ahead

If Claude Code has a habit of charging into code before you have agreed on a plan, PCWorld has a simple fix: start your prompt with “Stay in pencil and paper mode” or just “Pencil and paper mode.” According to senior writer Ben Patterson, that phrase pushes coding assistants to hold off on execution and talk through the work first.

Patterson says he has repeatedly had to hit the stop button when Claude began coding too early, leaving him unsure what had already been changed. He notes that Claude Code, OpenAI’s Codex, and Google’s Antigravity all offer planning modes meant to prevent that behavior, but says those tools do not always behave as expected, and users may forget to enable them.

He says the shortcut works as a plain-language instruction that most chatbots already understand. In one recent Claude Code session, he used this prompt:

“Stay in pencil and paper mode. What would be involved in removing the 'counter' readout in the top header?”

The point, he argues, is to make the intent explicit. Even prompts phrased as “what would be involved” or “how would that work” can still trigger immediate action from Claude Code or Codex.

Patterson adds that the prompt is not limited to coding. He says it can also be used for tasks like drafting a letter or organizing desktop folders when you want analysis before action. Another option is “ask clarifying questions first” or “ask me questions first,” which pushes the assistant to interview you before proceeding. But for a quicker discussion without a long back-and-forth, he says “pencil and paper mode” is the cleaner choice.
