 The core idea: agents cannot mark tasks complete themselves. They must call `lgtm_ask` with auditable evidence and explicit failure-mode analysis, then a human signs off via `/lgtm <id>`.
 
+Tasks can also carry a separate fresh-perspective robot review from a subagent or other model family. That review is observational only and never completes the task.

 The tool result includes a non-blocking self-check prompt asking whether the evidence directly addresses the `done_criterion` and whether a skeptical reviewer would find it convincing.
 
+### `robot_review_ask`
+
+Attach a fresh-perspective robot review to a task.
+
+Required fields:
+
+| Field | Description |
+|---|---|
+| `taskId` | Task to annotate |
+| `reviewer` | Model/provider/family/class used for the review |
+| `scope` | What the reviewer inspected |
+| `observations` | Concrete observations only. No advice, verdicts, or editorial |
+| `blind_spots` | What the reviewer did not inspect or could not verify |
+
+Use this from a separate subagent or other model when possible. The review is additive: it shows up as `🤖`, is visible in task detail and `/lgtm`, and does not complete the task.
