title: Show HN: A context-aware permission guard for Claude Code
additional: 🔒 Introducing "nah", a context-aware permission guard that classifies tool calls and applies policies, such as allowing, blocking, or asking for permission, based on the action type, like filesystem_read or git_history_rewrite, providing a scalable and customizable solution to manage permissions without compromising security. By using a deterministic classifier and optional LLM escalation, nah offers a robust and flexible way to control tool access, working out of the box with sane defaults and no dependencies required.
