Show HN: Whiteboard Defense – defend decisions of any system you've shipped (github.com)

A new tool called Whiteboard Defense has been launched, designed to help developers articulate and defend the decisions made by AI agents in customer-facing systems they've deployed. Developed as a skill and plugin for Claude Code, Codex, and OpenCode, it aims to enhance transparency by detailing what decisions were made, who made them, and the defaults that were used. This is particularly significant as AI agents often make numerous unseen decisions based on defaults or habitual patterns, which can create challenges in justifying their behavior to stakeholders. The Whiteboard Defense tool offers a range of commands to generate briefings on AI activities, including instant digests after key tasks, insights into default decisions, and quizzes to assess understanding. By tagging decisions as [USER], [INFERRED], [DEFAULT], or [GUESS], it helps developers prepare for inquiries about why certain choices were made. This capability not only fosters accountability but also encourages a deeper understanding of AI operations, ultimately promoting better design practices. The installation process is straightforward, requiring a single command, making it readily accessible for AI developers looking to enhance their project transparency.
