Paseo is an open-source AI agent harness and orchestration framework maintained by the getpaseo project. Designed for managing terminal-based and automated coding workflows, Paseo structures agent execution environments through modular packages, extensible skills, and dedicated execution runtimes. In daily use, Paseo acts as a bridge between LLM providers and developer environments. It uses a structured skills system (supporting standardized skill definitions in directories like `.agents/skills` and `.claude/skills`) and a plugin architecture to provide AI agents with fine-grained access to local tools, repositories, and execution contexts. Developers can configure agent behavior and constraints via project-level configuration files. Paseo differentiates itself through its strong emphasis on reproducibility and containerized runtime support. With built-in Nix environments, Docker configuration, and a modular monorepo architecture, Paseo provides predictable execution boundaries for autonomous agents, preventing uncontrolled side effects on host machines. Paseo is distributed as open-source software under an open license on GitHub. It is actively maintained with support for standard package managers, multi-runtime configurations via Mise, and modern linting infrastructure.
