About
AgentScan is a free, deterministic security scanner for AI agent skills. It checks a skill directory (Claude Code, Codex, OpenCode, MCP servers) for prompt injection, secrets, network calls, malware patterns, and obfuscation before you install it. Every finding has file:line evidence and a confidence score. It never runs the skill, never uploads anything, and works offline. Free and open source (MIT); Trust Pack adds 90 pre-audited skills via one command.

About
GPT-5.3-Codex-Spark is an ultra-fast coding model designed for real-time collaboration inside Codex. Built as a smaller version of GPT-5.3-Codex, it delivers over 1000 tokens per second when served on low-latency Cerebras hardware. The model is optimized for interactive coding tasks, enabling developers to make targeted edits and see results almost instantly. With a 128k context window, Codex-Spark supports substantial project context while maintaining speed. It focuses on lightweight, precise edits and does not automatically run tests unless prompted. Infrastructure upgrades such as persistent WebSocket connections significantly reduce latency across the full request-response pipeline. Released as a research preview for ChatGPT Pro users, Codex-Spark marks the first milestone in OpenAI’s partnership with Cerebras.
