OpenClaw

An agent framework / gateway that wraps the pi-agent-core runtime. It provides:

• RPC surface: agent, agent.wait, and other gateway commands.
• Session management: serialized per-session runs via session lanes + global queue.
• Hook system: both internal gateway hooks and plugin hooks at fine-grained lifecycle points.
• Streaming: bridges pi-agent-core events to structured assistant, tool, and lifecycle event streams.
• Skills: loaded as a snapshot and injected into env + system prompt.

Key concepts

• Agent Loop (OpenClaw) — the core execution path
• Command Queue — queue modes (collect/steer/followup) and lane system
• System Prompt — how the model's prompt is assembled
• Streaming — chunking and block reply behavior
• Compaction — long-context summarization
• OpenClaw Hooks — internal gateway hooks
• OpenClaw Plugin Hooks — plugin-level lifecycle hooks
