Understand OpenClaw by Building One - 7: More Context! More Context!

1. Every Agent Starts as a Loop 2. Gear up Your Agent 3. Pack the Conversation And Carry On 4. Beyond the CLI 5. Many of Them 6. Agents are Running, Your are Sleeping 7. More Context! More Context! All code snippets and working code bases are available at this repo . Multi-Layer Prompts: Context Stacking Getting the system prompt right is actually an non-trivial job. And a lot of pieces are not static. They're assembled from multiple layers, each adding context from different aspects. Identity — Rarely changes (agent's core purpose) Personality — Optional flavor, mostly static Bootstrap — Workspace guide, changes when you switch projects Runtime — Timestamp, session ID — every request Channel — Where the message came from — varies per request class PromptBuilder : def build ( self , state : " SessionState " ) -> str : layers = [] # Layer 1: Identity layers . append ( state . agent . agent_def . agent_md ) # Layer 2: Soul (optional) if state . agent . agent_def . soul_md : layers . appe
