AI coding agents / agent harness
Pi is an AI agent toolkit that provides a unified multi-provider LLM API, agent runtime with tool calling and state management, a TUI library, and an interactive coding agent CLI.
Same problem, same approach. Swapping one for another is a config change, not a rewrite.

These projects were analysed and named pi among their alternatives. The relationship is not symmetric — how pi rates them is a separate judgement, made when pi is analysed in its own right.
