Review

review/start runs the Codex reviewer for a thread and streams review items. Targets include:

• uncommittedChanges
• baseBranch (diff against a branch)
• commit (review a specific commit)
• custom (free-form instructions)

Use delivery: "inline" (default) to run the review on the existing thread, or delivery: "detached" to fork a new review thread.

Example request/response:

{ "method": "review/start", "id": 40, "params": {
  "threadId": "thr_123",
  "delivery": "inline",
  "target": { "type": "commit", "sha": "1234567deadbeef", "title": "Polish tui colors" }
} }
{ "id": 40, "result": {
  "turn": {
    "id": "turn_900",
    "status": "inProgress",
    "items": [
      { "type": "userMessage", "id": "turn_900", "content": [ { "type": "text", "text": "Review commit 1234567: Polish tui colors" } ] }
    ],
    "error": null
  },
  "reviewThreadId": "thr_123"
} }

For a detached review, use "delivery": "detached". The response is the same shape, but reviewThreadId will be the id of the new review thread (different from the original threadId). The server also emits a thread/started notification for that new thread before streaming the review turn.

Codex streams the usual turn/started notification followed by an item/started with an enteredReviewMode item:

{
  "method": "item/started",
  "params": {
    "item": {
      "type": "enteredReviewMode",
      "id": "turn_900",
      "review": "current changes"
    }
  }
}

When the reviewer finishes, the server emits item/started and item/completed containing an exitedReviewMode item with the final review text:

{
  "method": "item/completed",
  "params": {
    "item": {
      "type": "exitedReviewMode",
      "id": "turn_900",
      "review": "Looks solid overall..."
    }
  }
}

Use this notification to render the reviewer output in your client.
