 ### Changes
+- Plugins: add optional llm-task JSON-only tool for workflows. (#1498) Thanks @vignesh07.
 - CLI: restart the gateway by default after `clawdbot update`; add `--no-restart` to skip it.
 - CLI: add live auth probes to `clawdbot models status` for per-profile verification.
 - Docs: add cron vs heartbeat decision guide (with Lobster workflow notes). (#1533) Thanks @JustYannicc.

+---
+
+# 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:
+
+```json
+{
+  "plugins": {
+    "entries": {
+      "llm-task": { "enabled": true }
+    }
+  }
+}
+```
+
+2) Allowlist the tool (it is registered with `optional: true`):
+
+```json
+{
+  "agents": {
+    "list": [
+      {
+        "id": "main",
+        "tools": { "allow": ["llm-task"] }
+      }
+    ]
+  }
+}
+```
+
+## Config (optional)
+
+```json
+{
+  "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
+
+```lobster
+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).

+## JSON-only LLM steps (llm-task)
+
+For workflows that need a **structured LLM step**, enable the optional
+`llm-task` plugin tool and call it from Lobster. This keeps the workflow
+deterministic while still letting you classify/summarize/draft with a model.
+
+Enable the tool:
+
+```json
+{
+  "plugins": {
+    "entries": {
+      "llm-task": { "enabled": true }
+    }
+  },
+  "agents": {
+    "list": [
+      {
+        "id": "main",
+        "tools": { "allow": ["llm-task"] }
+      }
+    ]
+  }
+}
+```
+
+Use it in a pipeline:
+
+```lobster
+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
+  }
+}'
+```
+
+See [LLM Task](/tools/llm-task) for details and configuration options.
+
 ## Workflow files (.lobster)
 
 Lobster can run YAML/JSON workflow files with `name`, `args`, `steps`, `env`, `condition`, and `approval` fields. In Clawdbot tool calls, set `pipeline` to the file path.

+# 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
+`clawd.invoke --each`) without adding new Clawdbot code per workflow.
+
+## Enable
+
+1) Enable the plugin:
+
+```json
+{
+  "plugins": {
+    "entries": {
+      "llm-task": { "enabled": true }
+    }
+  }
+}
+```
+
+2) Allowlist the tool (it is registered with `optional: true`):
+
+```json
+{
+  "agents": {
+    "list": [
+      {
+        "id": "main",
+        "tools": { "allow": ["llm-task"] }
+      }
+    ]
+  }
+}

+
+## Config (optional)
+
+```json
+{
+  "plugins": {
+    "entries": {
+      "llm-task": {
+        "enabled": true,
+        "config": {

+          "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)
+- `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 Clawdbot internal modules (the embedded agent runner).
+It is intended to ship as a **bundled** Clawdbot extension (like `lobster`) and
+be enabled via `plugins.entries` + tool allowlists.
+
+It is **not** currently designed to be copied into
+`~/.clawdbot/extensions` as a standalone plugin directory.
