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 is OpenAI’s most advanced agentic coding model, designed to handle complex professional work on a computer. It combines frontier-level coding performance with advanced reasoning and real-world task execution. The model is faster than previous Codex versions and can manage long-running tasks involving research, tools, and deployment. GPT-5.3-Codex supports real-time interaction, allowing users to steer progress without losing context. It excels at software engineering, web development, and terminal-based workflows. Beyond code generation, it assists with debugging, documentation, testing, and analysis. GPT-5.3-Codex acts as an interactive collaborator rather than a single-turn coding tool.
