A second opinion is another agent reading what a session changed and telling you what it would push back on. It runs in the background, cannot edit anything, and its findings land in the session’s diff as held hunk comments. You read them, drop the ones you disagree with, and send the rest to the session that wrote the code.
Start one
There are three places to ask for one:
- History: right-click a session’s row in the History dropdown and pick Second opinion.
- The sidebar: right-click a worktree or a checked out branch and pick Second opinion. It reviews the newest session there that has unreviewed work. With none, the row stays in the menu and says No session here has unreviewed work.
- The Inbox: each Review row has a Second opinion icon at the end of its title, beside Mark reviewed.
A toast names the reviewer when it starts, and another says how many comments it left when it ends, or that it found nothing worth raising. While it runs, the menu items read Second opinion running and the Inbox icon is greyed out. Only one second opinion runs per session at a time.
What the reviewer reads
The reviewer gets the same work the Inbox shows for the session: everything it changed since it was last marked reviewed. With it goes what the session was asked to do in that stretch, so the review is against the task and not just the code.
- Lockfiles (
Cargo.lock,package-lock.json,pnpm-lock.yaml,yarn.lockand the like) are left out of the diff and named instead. - Past 2,000 changed lines, the remaining files are left out and named, and the reviewer can open them itself if they matter.
- A session that changed nothing since its mark, or only lockfiles, has nothing to review, and Tori says so instead of starting.
It is asked for bugs, missed requirements and risky changes, only on lines the session added or changed, and no style nits. A finding on a file the session did not change is dropped.
Read-only
The reviewer runs in the session’s own worktree, in its agent’s read-only mode: plan mode for Claude, the read-only mode for Codex. Tori checks the mode took before it sends anything, and stops the reviewer if it ever leaves it. Any permission it asks for is denied and any question it asks is answered with “nobody is here”, so it never waits on you. It gets 15 minutes, then it is stopped and the run is marked failed.
Only agents with a read-only mode Tori can confirm can review, which today is Claude and Codex. The reviewer’s session is listed in the worktree’s history like any other.
Pick the reviewer
Project settings > Agents > Second opinion picks who reviews in this project:
- A different agent from the session’s, the default: the first enabled agent that can review and is not the agent that wrote the code. When there is none, Tori tells you nobody can give a second opinion.
- An agent and account: that one always reviews, even a session by the same agent. If it is turned off later, Tori refuses and says it is not available.
There is no picker per run. Change the setting to change the reviewer.
The findings
When the session’s diff opens, its findings show up in the held comments count next to your own. Each one carries the reviewer’s name, and a stale tag once its file has changed since the review read it. Stale findings are kept: the line numbers may have moved, but the point usually still stands.
Send routes them by who wrote them:
- Your own comments go to the selected session, as before.
- The reviewer’s comments go to the session it reviewed, whichever session is selected. That session is resumed if it is not open. Each reads Codex (second opinion): the comment, so the agent knows it is not from you.
Remove this comment and Clear dismiss findings for good, and a sent finding does not come back. Findings are kept on disk per project, so they survive closing the diff or quitting Tori, until you mark the session reviewed.
In the Inbox
An Inbox row shows where its second opinion stands, next to its signals:
| Chip | Meaning |
|---|---|
| Second opinion running | The reviewer is still working |
| N second opinion comments | Findings you have not sent or dismissed yet. , stale is added when any of them is stale |
| Second opinion: nothing open | Every finding was sent or dismissed, or there were none |
| Second opinion failed | The reason shows under the chips, for example it timed out, left read-only mode, or answered without its findings |
The second opinion does not change the row’s score.
Mark reviewed deletes the session’s findings: they were about the work you just signed off. A reviewer still running at that moment has its findings thrown away when it finishes. Running a second opinion again replaces the earlier one.
Spending
A reviewer’s turns count toward the project’s spending like any chat. When the project is already at or past its per project ceiling, a second opinion will not start, and the toast says how much was spent of how much. The ceiling is checked only before a run, so a reviewer is never cut off halfway.
