The tool's quality has dropped significantly over the past three months. The AI is taking three times longer to solve problems and is still making many mistakes. Accuracy has decreased by at least 60%. I had to manually fix everything and stop using the prompt. Unfortunately, it used to work very well for me, but now it no longer does.

Really impressed with CodeThreat! It’s great to have a free tool that detects both code vulnerabilities and library risks. The setup was smooth, and it fits well into CI/CD pipelines. Definitely worth checking out!
