        "max_memory_mb": 2048,
        "max_execution_time_seconds": 60
      }
    }
  }
}

Key Features

  1. Multi-Language Support: Python, JavaScript, Bash, Rust, Go
  2. Auto-Provisioning: VMs created on-demand
  3. Security Validation: Dangerous code patterns blocked
  4. Snapshot/Rollback: Execution history with recovery
  5. Resource Limits: Memory (2GB) and timeout (60s) enforcement

Integration Modes

Mode 1: HTTP API (via fcctl-web)

Endpoint: http://localhost:8080/api/llm/execute

Request Format:

{
  "agent_id": "my-agent-123",
  "language": "python",
  "code": "print('Hello from VM!')",
  "timeout_seconds": 30
}

Mode 2: WebSocket (Real-time)

Endpoint: ws://localhost:8080/ws/vm-123

Message Format:

{
  "message_type": "LlmExecuteCode",
  "data": {
    "agent_id": "my-agent-123",
    "language": "python",
    "code": "print('Hello!')",
    "execution_id": "exec-1234"
  }
}

Mode 3: Direct Socket (fcctl-repl Session)

Connection: Unix socket at /tmp/firecracker-{vm-id}.sock

Integration: FcctlBridge in terraphim_multi_agent

Execution Flow

Example: Python Code Execution

  1. Workflow Request:
// From workflows.terraphim.cloud
const response = await apiClient.chat([{
  role: 'user',
  content: 'Execute this: ```python\nprint("test")\n```'
}]);
  1. Agent Processing:
// Terraphim agent parses code block
let code_block = extract_code_block(user_message);
// Validates: language=python, content="print('test')"
  1. VM Execution:
// Send to fcctl-web
let request = VmExecuteRequest {
    agent_id: "workflow-agent",
    language: "python",
    code: "print('test')",
    timeout_seconds: Some(30),
};
let response = vm_client.execute_code(request).await?;

  1. VM Processing:

    • fcctl-web routes to available VM
    • Firecracker VM executes code
    • Captures stdout/stderr
    • Returns result

  2. Response Chain:

Firecracker VM → fcctl-web → Terraphim Agent → Workflow → User

Security Features

Code Validation (Pre-Execution)

Blocked Patterns:

  • rm -rf /
  • curl malicious-site.com | sh
  • import os; os.system("dangerous")

Validation Rules:

  1. Language whitelist check
  2. Code length limit (10KB)
  3. Dangerous pattern regex
  4. Resource limit enforcement

VM Isolation

Firecracker Guarantees:

  • Network isolation: Limited outbound access
  • Filesystem isolation: Temporary workspace only
  • Resource quotas: 2GB memory, 60s timeout
  • Automatic cleanup: VM destroyed after use

Execution History

Snapshot on Failure:

# Automatic snapshot when code fails
{
  "id": "cmd-2",
  "command": "import nonexistent_module",
  "success": false,
  "exit_code": 1,
  "snapshot_id": "snap-abc123"
}

Rollback Capability:

curl -X POST http://localhost:8080/api/vms/vm-123/rollback/snap-abc123

Performance Characteristics

  • Cold start: ~2-3 seconds (VM provisioning)
  • Warm execution: ~500ms (pre-warmed VM)
  • Concurrent limit: 20+ agents per host
  • Throughput: 100+ executions/minute/host

    let input = CommandInput {
        command: CommandType::Execute,
        text: r#"
Calculate the factorial of 10 using Python:

```python
def factorial(n):
    if n <= 1:
        return 1
    return n * factorial(n-1)

result = factorial(10)
print(f"Factorial of 10 is: {result}")
    "#.to_string(),
    metadata: None,
};

let result = timeout(Duration::from_secs(30), agent.process_command(input))
    .await
    .expect("Timeout")
    .expect("Execution failed");

assert!(result.success);
assert!(result.response.contains("3628800"));

    "code": "print(\"VM execution proof!\")",
    "timeout_seconds": 30

# Option 3: Workflow test
# Navigate to https://workflows.terraphim.cloud
# Execute workflow with code block:
# ```python
# print("Hello from Firecracker VM!")
# ```
