Catches AI hallucinations in code diffs before they merge.
HalluCheck reviews AI-generated code diffs for hallucinated APIs, non-existent methods, wrong signatures, and fabricated dependencies — before they make it into your codebase.
/ the problem
Copilot and Claude suggest code that looks right but calls methods that don't exist, uses APIs with wrong signatures, or imports packages with fabricated names. HalluCheck catches these before they hit CI — or worse, production.
/ how it works
Extracts every function call, import, and API reference from the AI-generated changes
Cross-checks each reference against actual installed packages and language specs
Surfaces non-existent methods, wrong argument counts, fabricated imports with confidence scores
Claude explains what was hallucinated and suggests the correct real-world alternative
/ use cases
MIT licensed. One command install. Works in CI today.
