Contract-Guard

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.

  Coder 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…

  VSCan - Detect Malicious VSCode Extensions2025 · vscan.dev · ▲52

  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…

  Free 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%…

  Hi HN, I’m experimenting with commit-based code review as an alternative to PR-based review. Instead of analyzing large PR diffs, this reviews each commit incrementally, while context is still fresh. It’s fully configurable and intentionally low-noise, high signal - focused on catching issues that tend to slip through and compound over time. The goal isn’t to replace CI or PR review, but to move some feedback earlier: risky changes hidden in small diffs architectural or consistency drift performance or security footguns Happy to answer questions

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  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…
