Eliminating Cognitive Debt in AI-Assisted Code

AI can write the code.
UnderstandGuard makes sure you understand the change.

Instead of passively skimming AI-generated pull requests, UnderstandGuard conducts an interactive reverse-interview on critical lines. When comprehension is weak, it flags cognitive debt, synthesizes targeted adversarial tests, and provides senior engineering coaching.

Pre-Merge Accountability Check

UnderstandGuard will parse the diff hunks, identify critical state/concurrency mutations, and generate 3 line-specific interview questions for the author.
