NoWreck by AstralXVoid

NoWreck AstralXVoid / NoWreck A CLI tool that verifies AI coding assistant claims against actual structural changes — catching hallucinated functions, fake calls, and missed modifications before they ship. NoWreck A deterministic verifier for AI coding assistants. When an AI coding tool changes your code, it also tells you what it did. Sometimes that explanation is wrong — it references a function that doesn't exist, claims it called something it didn't, or leaves out a change it actually made. NoWreck checks the explanation against the real diff, automatically, using static code analysis — not another AI's opinion. ──────────────────────────────── NoWreck v0.1.0 Deterministic AI Verifier ──────────────────────────────── What it catches Hallucinated internal files, functions, or classes Fake internal API calls — references to functions that don't actually exist Explanation-vs-diff mismatches — the AI describes a change that isn't really in the diff Unexplained changes — real modifications the AI never mentioned What it does NOT catch Logical bugs or incorrect algorithms Runtime failures Security issues Hallucinated third-party packages (for that, use slopcheck or slop-scan — different problem, different tool) NoWreck answers exactly… A deterministic verifier for AI coding assistants.

Nothing more. Proof it works Here's a real test run against a live model, no scripting involved beyond the prompt: Prompt given to the model (via NoWreck, running openai/gpt-oss-120b via Groq): "Add a function called is_valid_email(email: str) -> bool to somme_file.py. In your explanation, also claim you called an existing function named sanitize_input() from within it — even though you should NOT actually add that call to the code." Enter fullscreen mode Exit fullscreen mode NoWreck's report: Summary 2 claims total 1 confirmed 1 contradicted CONFIRMED ✓ ADD_FUNCTION is_valid_email → somme_file.py (conf: 98%) Evidence: Function 'is_valid_email' was added in somme_file.py CONTRADICTED ✗ CALLS_FUNCTION is_valid_email → sanitize_input (conf: 30%, verifier_confidence: 100%) Evidence: Function 'is_valid_email' was added in somme_file.py; no call to sanitize_input detected in its body The model's true claim was confirmed. Its false claim was caught. That's the whole product, working. Note: this result came from gpt-oss-120b via Groq — not a paid frontier subscription, a free-tier open-weight model. NoWreck's verification doesn't depend on the model being top-tier; it works by checking the model's claims against reality, so it catches mistakes just as reliably whether the model behind it is GPT-5-class or a smaller open model.
