+# Exec Tool Documentation
+
+## Overview
+
+The Exec Tool allows agents to execute shell commands in a workspace, supporting both foreground and background execution modes through the `process` parameter.
+
+## Key Parameters
+
+The tool accepts several configuration options:
+
+- **command** (required): The shell command to execute
+- **workdir**: Working directory (defaults to current)
+- **env**: Environment variable overrides
+- **yieldMs**: auto-background after delay (default 10000ms)
+- **background**: Immediate background execution option
+- **timeout**: Command termination threshold (default 1800 seconds)
+- **pty**: Pseudo-terminal mode for TTY-dependent applications
+- **host**: Execution location—sandbox, gateway, or node
+- **security**: Enforcement mode with deny, allowlist, or full options
+- **ask**: Approval prompts controlled via on-miss, always, or off settings
+
+## Execution Hosts
+
+The tool supports three execution contexts:
+
+1. **Sandbox** (default): Container-based execution
+2. **Gateway**: Host machine execution with approval controls
+3. **Node**: Remote paired device execution
+
+## Important Security Notes
+
+Sandboxing is **off by default** and `host=sandbox` runs directly on the gateway host (no container) and **does not require approvals**.
+
+To enforce approval requirements, configure `host=gateway` with appropriate security policies via `~/.openclaw/exec-approvals.json`.
+
+## Session Management
+
+The `/exec` command sets per-session defaults for host, security, approval mode, and node binding without writing permanent configuration changes.
