Phi is a high-performance terminal coding agent built in Go that provides a TUI for running AI-driven coding tasks. It supports sub-agents that run in isolated jobs, hashline-based file edits using anchor tags, a permission gate for destructive tools, and MCP integration without context bloat. The binary is small (~15 MB) and starts quickly, with no Node, Electron, or Python runtime required.
