Agent Meter shows an amber menu bar alert when an agent pauses for permission and lets users click \"Allow ⏎\" or \"Deny Esc\" inline, previews the latest terminal output of local and SSH sessions, tracks each session's 5-segment context window usage as a percentage, and launches new sessions from a \"+\" menu. The app requires macOS 14.0+, the Rex terminal (other terminal emulators are not supported), and Swift 6.0+, and is built via `zsh scripts/build-app.sh` or `swift build -c release`.", "body_md": "English | [简体中文](https://github.com/amazingyyc/AgentMeter/blob/main/README_zh.md)\n\nA native macOS menu bar CLI Agent monitor (**Rex terminal only**).
