What runs
- A background service and a menu bar item (QuintAgent). There is no Dock icon.
- Two system extensions that record which processes your AI coding agents start, which files they touch and where they connect.
- A small hook inside the coding agents Quint supports (Claude Code, Codex, Cursor, Gemini CLI and others). See Supported agents. The hook tells Quint what the agent is about to do, before it does it.
