Overview

Sandboxing controls the agent’s ability to interact with your system. It determines which tools are available, which operations need approval, and what actions are blocked entirely.

​
Sandbox Modes

{ "security": { "mode": "unrestricted" } }
  • All tools available
  • No approval required
  • Suitable for: trusted personal environments, development

​
Tool Policies

Fine-grained policies override the global sandbox mode for individual tools: 
{
  "toolPolicies": {
    "exec": {
      "mode": "approval-required",
      "blockedPatterns": [
        "rm -rf",
        "sudo",
        "chmod 777",
        "mkfs",
        "> /dev/"
      ],
      "allowedPaths": [
        "/Users/sem/projects/",
        "/tmp/"
      ]
    },
    "browser": {
      "mode": "allowed",
      "blockedDomains": [
        "banking.example.com",
        "*.internal.company.com"
      ]
    },
    "memory_store": {
      "mode": "allowed"
    },
    "memory_recall": {
      "mode": "allowed"
    }
  }
}

​
Blocked Patterns

The blockedPatterns array uses substring matching against the command string. If any pattern matches, the command is rejected without asking for approval. Common patterns to block:
PatternReason
rm -rf /Prevents recursive deletion of root
sudoPrevents privilege escalation
chmod 777Prevents world-writable permissions
mkfsPrevents filesystem formatting
> /dev/Prevents writing to device files
“ :(){ ::& };: “Fork bomb

​
Approval Flow

When an operation requires approval:
A modal appears with the command or action details. The user clicks “Approve” or “Reject.”
If no approval is received within a configurable timeout (default: 5 minutes), the operation is rejected automatically.

​
Path Restrictions

The allowedPaths array restricts where the exec tool can operate: 
{
  "exec": {
    "allowedPaths": ["/Users/sem/projects/", "/tmp/"]
  }
}
Commands that attempt to access paths outside the allowed list are blocked.

​
Testing Your Sandbox

# Verify current security mode
argent config get security.mode

# Test a command against policies
argent security test "rm -rf /tmp/old-files"
