 Standing orders are defined in your [agent workspace](/concepts/agent-workspace) files. The recommended approach is to include them directly in `AGENTS.md` (which is auto-injected every session) so the agent always has them in context. For larger configurations, you can also place them in a dedicated file like `standing-orders.md` and reference it from `AGENTS.md`.

 The system prompt is built in `buildAgentSystemPrompt()` (`system-prompt.ts`). It assembles a full prompt with sections including Tooling, Tool Call Style, Safety guardrails, OpenClaw CLI reference, Skills, Docs, Workspace, Sandbox, Messaging, Reply Tags, Voice, Silent Replies, Heartbeats, Runtime metadata, plus Memory and Reactions when enabled, and optional context files and extra system prompt content. Sections are trimmed for minimal prompt mode used by subagents.
