Harness Integration overview

Harness Integration as a cross-cutting topic - how different agent harnesses integrate with the babysitter SDK for orchestrated workflows. Covers adapter implementations for Claude Code, Codex, Gemini CLI, oh-my-pi (OMP), OpenCode, Pi, Cursor, Copilot CLI, Hermes, and others. Each adapter translates between the unified AgentAdapter interface and the native CLI of its target agent, handling spawn arguments, event parsing (JSONL/SSE/streaming), session management, thinking normalization, and platform-specific behavior. The hooks-mux layer normalizes hook events across harnesses.
