AgentGuard
A realtime codebase safety layer for AI assisted development
Get picks like this daily. Today's launch numbers, the top launches, AI and tech news, and a daily opportunity pick, straight to your inbox.
AI coding tools can change files in seconds—and silently break code you never touched. AgentGuard is a local-first VS Code extension that monitors changes in real time, highlights potential impact across files, flags suspicious edits to critical logic (auth, permissions, validation, error handling), and tracks new diagnostics. Findings update as issues are fixed. Works with AI coding assistants—no AI API key or cloud account required.

Could you build this?
Partial The VS Code extension shell and real-time file watching are easy to build, but meaningful cross-file impact analysis and reliable detection of risky edits to auth or validation logic need real static analysis that vibe coding won't produce on its own.
What it would actually take: A real version would be a VS Code extension using the file-system and diff APIs, with Tree-sitter or the Language Server Protocol to build a per-language dependency and call graph. The hard part is accurate impact analysis and classifying critical logic across many languages with few false positives. That requires compiler and static-analysis expertise and testing against real codebases.
