This is exactly the problem that Anthropic hides in their article. Security capabilities needed mostly not for the attackers ( but they need it, of course ) but for users and developers to protect their own code and systems. I do use glm ( from openrouter and abliteration.ai ), and kimi model for security reviews on pull requests. Claude rejected even to edit instruction files. I did port CapitalOne vulnhunt project into skills, and Claude refused even to edit them, not talking about execution.
