Ouroboros tool blocks AI coding agents from starting until requests meet clarity threshold

An open-source tool called Ouroboros introduces an 'ambiguity gate' that prevents AI coding agents from generating code until a user's request meets a defined clarity score. The system scores requests across three dimensions — goal clarity, constraint clarity, and success-criteria clarity — and blocks spec generation until the overall ambiguity score falls below 0.2. Each dimension also has its own minimum floor, so strong scores in one area cannot compensate for vagueness in another. Users retain the option to override the gate and force spec generation, making vagueness a deliberate choice rather than an accidental one. The tool aims to shift iteration from the costly post-code review stage to an earlier interview phase, where clarifying a wrong assumption requires only an answered question rather than a discarded implementation.
