NoWreck - AI says it changed the code. NoWreck checks.

NoWreck is a developer tool for verifying claims made by AI coding agents.

AI coding agents can modify a codebase and confidently explain what they changed, but their explanations are not necessarily evidence. NoWreck is designed to independently check those claims against observable changes in the repository.

NoWreck analyzes source files, builds symbol indexes, detects structural changes, parses AI-generated claims, and compares those claims against detected evidence. Each claim is classified as verified, contradicted, or unverifiable rather than being blindly accepted.

The goal is deliberately narrow: NoWreck does not judge whether the code is good, correct, secure, or well-designed. It checks whether the agent's claims correspond to observable changes.

Current development focuses on expanding claim coverage and language support, with future work aimed at making Prompt Mode fully independent by verifying claims against actual before/after repository states rather than evidence derived from the model's own output.

AI can make the change. AI can explain the change. NoWreck checks whether the explanation matches reality.
