CLI-Anything is a meta-framework for generating agent-native CLI interfaces for arbitrary GUI applications. The repository contains 40+ pre-built CLI harnesses (e.g., Blender, GIMP, Audacity, LibreOffice, OBS Studio) each structured as a self-contained Python package under `cli_anything.<name>/`. These harnesses provide a consistent Click-based CLI with `--json` output, interactive REPL mode, session management with undo/redo, and backend abstraction over subprocess or API calls. The project also includes a CLI-Hub package manager, agent plugins for Claude Code, Pi, Codex, Hermes, and a skill generation system. The primary data flow is: agent/user invokes a CLI command → harness translates to subprocess/API calls to the target software → structured output returned. External dependencies are the target software binaries (must be pre-installed). The codebase is well-tested (2,461 tests passing) and actively maintained, though significant code duplication exists across harnesses.
