LLM Task (plugin)

Adds an optional agent tool llm-task for running JSON-only LLM tasks (drafting, summarizing, classifying) with optional JSON Schema validation.

Designed to be called from workflow engines (for example, Lobster via openclaw.invoke --each) without adding new OpenClaw code per workflow.

Enable

1. Enable the plugin:

{
  "plugins": {
    "entries": {
      "llm-task": { "enabled": true }
    }
  }
}

2. 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 API

Parameters

• prompt (string, required)
• input (any, optional)
• schema (object, optional JSON Schema)
• provider (string, optional)
• model (string, optional)
• thinking (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).

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.
• Side effects should be handled outside this tool (for example, approvals in Lobster) before calling tools that send messages/emails.

Bundled extension note

This extension depends on OpenClaw internal modules (the embedded agent runner). It is intended to ship as a bundled OpenClaw extension (like lobster) and be enabled via plugins.entries + tool allowlists.

It is not currently designed to be copied into ~/.openclaw/extensions as a standalone plugin directory.
