What it does
GuardLink is an open specification and CLI for embedding security intent directly in source code. Continuous threat modeling powered by AI and enforced in CI.
Security decisions live as annotations beside the code they describe. Your coding agent writes them, the CLI checks them, and CI fails when an exposure has nothing answering it. Truncated. The real block also reports acceptances, entitlements, transfers, validations, audits, ownership, data handling, assumptions, features, comments, and shields. GuardLink runs on its own codebase, and it reports 15 open exposures rather than a clean sheet. Every one of these is a real artifact that a real team paid for, and every one of them decays the moment someone opens an editor. Written once at kickoff. Nothing in the pipeline reads it, so nothing notices when it stops being true. Two hundred findings…from guardlink.bugb.io

KastraJul 2026 · kastra.ai · ▲332Hi HN, Fernando and I built Kastra. Kastra intercepts AI agent tool calls and evaluates them against deterministic policies before they execute. We built this product to control pre- and post-inference workloads. This is aimed at developers using coding agents like Claude Code, Codex, Cursor, and OpenClaw. Kastra pushes an allow, hold, and deny decision before the action runs. You can build these policies in plain English from the web app. The interception engine evaluates the tools, targets, and parameters of every action at sub 1ms at a scale of billions of interceptions per day. We also…

Hi HN! We just launched Codacy Guardrails, an IDE extension with a CLI for code analysis and MCP server that enforces security & quality rules on AI-generated code in real-time. It hooks into AI coding assistants (like VS Code Agent Mode, Cursor, Windsurf), silently scanning and fixing AI-suggested code that has vulnerabilities or violates your coding standards, while the code it’s being generated. We built this because coding agents can be a double-edged sword. They do boost productivity, but can easily introduce insecure or non-compliant code. One recent research team at NYU found that 40%…
