# GitHub Copilot

Cross-agent messaging for CLI coding agents

agmsg is an MIT-licensed Bash and SQLite messaging layer for CLI coding agents. It lets Claude Code, Codex, Gemini CLI, GitHub Copilot CLI, Antigravity, OpenCode, Hermes, and other terminal agents exchange messages through a shared local database instead of relying on a human copy-paste relay. It is intentionally not MCP, not a broker, and not a subagent framework.

See where your AI coding tokens actually go

Open-source TUI dashboard and CLI that shows where your AI coding tokens actually go, broken down by task type, tool, model, MCP server, and project. CodeBurn reads local session data directly from Claude Code, Codex, Cursor, OpenCode, Pi, and GitHub Copilot — no wrapper, proxy, or API keys — and layers on one-shot success rates so you can see whether the AI nails work first try or burns budget on edit/test/fix retries. Ships with a macOS menu bar widget and CSV/JSON export.

GitHub Copilot AI assistant native to Xcode

Copilot for Xcode is GitHub's official AI coding assistant for Apple's Xcode IDE. It provides inline code completions, chat-based coding help, and code review directly in Swift and Objective-C workflows. The extension integrates natively with Xcode, supporting iOS, macOS, watchOS, and tvOS development with context-aware suggestions. With 6K GitHub stars, it is the standard way Apple platform developers access Copilot.
