AGI CLI (agi-cli / agents-cli) is an open-source terminal agent harness and orchestration framework developed by phnx-labs. It provides a modular command-line infrastructure designed to run, manage, and coordinate AI coding agents directly within developer workspaces. In day-to-day operation, AGI CLI coordinates multi-agent routines and tool invocation through a structured CLI environment. The harness leverages project-level configuration and context files (such as CLAUDE.md and GEMINI.md) to integrate with major foundation models including Anthropic Claude and Google Gemini, delegating specific coding and automation tasks across repository workflows. AGI CLI differentiates itself through a modular skills architecture and dedicated configuration surfaces defined under open specifications. Its codebase incorporates native bindings, distinct agent definitions, and reusable skills modules that decouple task execution logic from the underlying LLM harness. The project is fully open source under the phnx-labs organization on GitHub, distributed as a monorepo containing modular npm packages and native CLI tooling.
