phi
A minimal terminal coding agent harness in Go
Visit pulseaiclub.github.io ↗What is phi?
phi is a lightweight terminal-based agent framework written in Go that manages AI coding tasks with careful resource management. It features sub-agents for isolated jobs, hashline edits to target specific code locations, permission gates for safety, and MCP server integration without inflating the model context. The ~12 MB binary runs on macOS, Linux, and Windows with support for OpenAI-compatible and Anthropic models.
Designed for developers who want a lean, performant alternative to web-based IDEs, phi emphasizes efficiency and control. It includes in-TUI diff review for staged changes, extensibility via native binaries through the PXB protocol, and skills packaging for reusable procedures. The maker built it in Go to eliminate Node, Electron, and Python runtime dependencies.
