AI coding assistants such as Claude Code, Codex, and Antigravity often begin writing code before users can outline their intentions. This tendency forces developers to interrupt the process and salvage incomplete or unwanted work.
These tools include planning modes intended to prevent premature action. However, those features do not always function as expected, and users may forget to enable them.
A practical workaround is to prepend the phrase “pencil and paper mode” to a prompt. This instruction signals the assistant to discuss approach and scope before generating any code.
The method works across multiple AI chatbots and is not limited to software development. It can be applied to tasks such as drafting documents or organizing files.
Standard phrasing like “what would be involved” does not reliably stop autonomous execution. Explicitly stating “pencil and paper mode” removes ambiguity and keeps the assistant in a consultation phase.
An alternative is “ask clarifying questions first,” which prompts the model to seek input before proceeding. For quick analysis without extended questioning, the pencil and paper approach remains more efficient.
