Contract-Guard
Free and local code, config, dependency and security scanner
What it does
ContractGuard is a local first VS Code extension that finds security and reliability issues in code, configs, queries, Dockerfiles, and dependency files directly inside the editor. It provides inline diagnostics, a dedicated findings explorer, incremental rescans, severity filtering, SARIF and JSON export, dependency vulnerability checks, secret detection, SQL analysis, regex ReDoS detection, and schema drift analysis without requiring external services.

- CGCoder Guard – Protect Your IDE from Malicious Extensions2023 · ▲10
There is a growing problem with VSCode extensions: - they're not sandboxed (yet) - just like double-clicking an .exe file - they don't have a permission model - they auto update - they have built-in persistence - they are installed on developer machines with high-value credentials The recent CircleCI and LastPass incidents were both suspected to originate from a compromised developer machine - which is becoming every organization's Achilles heel in terms of cyber posture So I've been working on a way to help mitigate some of these risks Right now, only an MVP of a "CLI" is available: $ code…

Did you know that VSCode extensions run with full access to your system—including file system, network, and credentials? Worse, dozens of malicious extensions have already made it into the marketplace, silently compromising devices. I am a security researcher and student developer who ran into this problem myself. To help tackle this, I built a 100% free tool (no login required) that scans VSCode (and Cursor/Windsurf) extensions for: - Hidden malware and obfuscated code - Dangerous permissions and API misuse - Vulnerable dependencies and suspicious network connections Users have already…
- FLFree local security checks for AI coding in VSCode, Cursor and Windsurf2025 · ▲43
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%…

Parallel agents, diff reviewer, and multi-model comparisons

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
