What problem does it solve? Setting up an agentic engineering harness across multiple AI coding tools (Claude Code, Codex, Antigravity CLI) requires manual configuration of methodologies, hooks, model routing, and quality modes. This Skill guides the installation, configuration, and maintenance of Autopus-ADK so the harness works consistently across platforms. ## Core Features & Use Cases - Guided Installation: Install the harness in Full or Lite mode via auto init, targeting specific platforms like claude-code or codex. - Configuration Management: Explains the autopus.yaml settings for methodology (TDD), hooks, and per-provider quality modes (Ultra/Balanced). - Model Routing Guidance: Documents Opus 5 and Fable 5 model selection, version requirements, and pricing for OMP providers. - Troubleshooting: Diagnose installations with auto doctor, validate config, and reinstall while preserving user edits. - Use Case: A developer wants TDD enforcement and lore commits in both Claude Code and Codex; this Skill walks them through auto init --mode full --platforms claude-code,codex and verifying with auto doctor. ## Quick Start Ask the agent to install the Autopus harness in full mode for Claude Code and Codex, then run auto doctor to verify the setup.
