When Skills Don't Help: A Negative Result on Procedural Knowledge for Tool-Grounded Agents in Offensive Cybersecurity
Recent research indicates that while AI 'Skills' can improve agent performance in cybersecurity, their benefit diminishes significantly in offensive scenarios, potentially even degrading performance. This is attributed to a lack of 'environment-feedback bandwidth,' where rich, low-latency observations from the environment reduce the need for pre-programmed procedural knowledge. Meanwhile, frontier AI models like Anthropic's Claude Mythos and OpenAI's GPT-5.5-Cyber are demonstrating advanced capabilities in discovering zero-day vulnerabilities and synthesizing exploits, reshaping both offensive and defensive cybersecurity strategies.
