KISS

KISS is a performant agent harness built in Rust, inspired by Pi, designed as a terminal-based coding assistant. It integrates multiple AI model providers (including OpenAI Codex, Anthropic, Meta Muse, and others) and offers features like session persistence, automation of long tasks, subagents, and dynamic workflows. It supports extensibility through Rust, Python, TypeScript, WebAssembly, and RPC interfaces, emphasizing simplicity and control for developers.
