Define the Tool Layer in OpenClaw's architecture?

The Tool Layer is the architectural component responsible for actually carrying out the actions an agent decides to take, file access, shell commands, browser automation, and calls to external services.

• Receives dispatched tool calls from the Agent Runtime once the model decides an action is needed
• Executes that action, optionally inside a sandbox if one is configured
• Returns the result back into the conversation so the agent's next reasoning step can factor it in

This is the layer where OpenClaw's real-world capability, and real-world risk, actually materializes, since it's the point where a model's decision turns into an action with real consequences on the host system.
