Show HN: Geiger – See every AI agent on your machine and what it can touch

Geiger is an open-source tool designed to identify and analyze AI agents on a machine, functioning like a "Geiger counter for AI agents." It detects various agents, including Claude Code, Gemini CLI, and GitHub Copilot CLI, across platforms like VS Code, JetBrains IDEs, and browser extensions. For each finding, Geiger reports its origin, capabilities such as EXECUTES or HOLDS-SECRETS, and the evidence path for verification. Built by Atomburst, it has zero runtime dependencies and an MIT license.
