LLM Task

llm-task is an optional plugin tool that runs a JSON-only LLM task and returns structured output (optionally validated against JSON Schema). This is ideal for workflow engines like Lobster: you can add a single LLM step without writing custom Clawdbot code for each workflow.

​
Enable the plugin

  1. Enable the plugin:
{
  "plugins": {
    "entries": {
      "llm-task": { "enabled": true }
    }
  }
}
  1. Allowlist the tool (it is registered with optional: true):
{
  "agents": {
    "list": [
      {
        "id": "main",
        "tools": { "allow": ["llm-task"] }
      }
    ]
  }
}

​
Config (optional)

{
  "plugins": {
    "entries": {
      "llm-task": {
        "enabled": true,
        "config": {
          "defaultProvider": "openai-codex",
          "defaultModel": "gpt-5.2",
          "defaultAuthProfileId": "main",
          "allowedModels": ["openai-codex/gpt-5.2"],
          "maxTokens": 800,
          "timeoutMs": 30000
        }
      }
    }
  }
}
allowedModels is an allowlist of provider/model strings. If set, any request outside the list is rejected.

​
Tool parameters

  • prompt (string, required)
  • input (any, optional)
  • schema (object, optional JSON Schema)
  • provider (string, optional)
  • model (string, optional)
  • authProfileId (string, optional)
  • temperature (number, optional)
  • maxTokens (number, optional)
  • timeoutMs (number, optional)

​
Output

Returns details.json containing the parsed JSON (and validates against schema when provided).

​
Example: Lobster workflow step

clawd.invoke --tool llm-task --action json --args-json '{
  "prompt": "Given the input email, return intent and draft.",
  "input": {
    "subject": "Hello",
    "body": "Can you help?"
  },
  "schema": {
    "type": "object",
    "properties": {
      "intent": { "type": "string" },
      "draft": { "type": "string" }
    },
    "required": ["intent", "draft"],
    "additionalProperties": false
  }
}'

​
Safety notes

  • The tool is JSON-only and instructs the model to output only JSON (no code fences, no commentary).
  • No tools are exposed to the model for this run.
  • Treat output as untrusted unless you validate with schema.
  • Put approvals before any side-effecting step (send, post, exec).
