Code Node

The code node is designed to execute arbitrary JavaScript in an isolated environment. It is currently disabled while Pod VM infrastructure (Kata Containers / Firecracker) is being provisioned.

Code node execution is disabled. Invoking this node will immediately fail the execution with: "Code node execution is currently disabled. Arbitrary code execution requires a dedicated Pod VM for safe sandboxing."

Use the Agent node with the run_javascript tool as an interim solution (requires human approval per run).

Planned Configuration

Once enabled, the node will accept:

Field	Type	Default	Description
`code`	string	—	JavaScript to execute. `input` is bound to `lastOutput`. Must assign to `output`.
`language`	`javascript`	`javascript`	Language (only JavaScript planned initially)
`timeoutMs`	number	`5000`	Execution timeout

Planned Example

const lines = input.split('\n');
output = lines.map(l => l.trim()).filter(Boolean);

Alternative: Agent + `run_javascript` Tool

Until the Code node is available, enable the run_javascript built-in tool on an Agent node:

{
  "model": "claude-haiku-4-5-20251001",
  "instructions": "Run this transformation: {{input.codeRequest}}",
  "tools": ["run_javascript"]
}

Note that run_javascript always requires human approval due to the approval: 'always' policy.
