PromptSonar is a Visual Studio Code extension that acts as a static scanner for prompt injection patterns (OWASP LLM01), API key leaks, and jailbreak attempts in source code. Analysis runs entirely locally with no calls to an LLM, enabling fast scans without cloud dependency. The tool is described as open source and targets developer teams seeking automated first-pass prompt security review before deployment.
