Discover OpenClaw, the viral open-source assistant that moves beyond chat to control your files, browser, and hardware. Learn how to set up the agentic loop to automate your digital life via WhatsApp, Discord, or shell commands.

The most important step—the one people always skip—is the structured onboarding. Instead of just saying 'Be my assistant,' you should tell the bot to interview you to build a foundational layer of who you are in its memory.
The Brain and Muscle split is a framework used to optimize performance and cost. A powerful "Brain" model, such as Claude Opus, is used for high-level reasoning, planning, and maintaining the assistant's personality. Meanwhile, specialized "Muscle" models handle specific technical tasks, such as DeepSeek Coder for writing scripts or Whisper for transcribing voice notes, ensuring that expensive tokens aren't wasted on simple execution.
Unlike standard chatbots that forget information once a conversation becomes too long, OpenClaw uses a persistent knowledge graph and markdown files to store preferences. It employs a "compaction" strategy to summarize long exchanges, but users are encouraged to be intentional by telling the bot to "commit" specific workflows to memory. Additionally, a "SOUL.md" file allows users to hard-code the assistant's permanent personality and "North Star" principles.
OpenClaw bridges the gap between digital logic and physical movement by integrating with ROS 2 (Robot Operating System). The AI acts as a "decision layer" that interacts with ROS 2 "topics" to see what the robot sees and "services" to execute specific actions, like moving a gripper. This allows the robot to move from following rigid, hard-coded scripts to executing complex missions based on real-time environmental analysis.
Sub-agents are focused, independent workers spawned by the main system to handle specific, narrow goals like scanning emails or reporting the weather. They are primarily used in scheduled "heartbeat" or cron jobs to increase reliability. By delegating tasks to a sub-agent, the main system is protected from crashing if a specific task fails, and the sub-agent can leave a "tangible output" or digital paper trail of its progress in markdown files.
Security hygiene is critical when giving an AI agent shell access to a computer. Users should never put API keys directly into configuration files, opting for environment variables instead. It is also vital to keep the system isolated and avoid granting "root" or elevated privileges. Tools like "openclaw doctor" should be used regularly to check for vulnerabilities, and gateway tokens must be treated with the same level of secrecy as bank passwords.
