what we call minion internally. So this is … background coding agent. So around 15% of all of the production … go through minion right now. … Once you have for the task that I have really good spec, or I want to do minimal steering, I can hand off that to a minion.

Context. Medisetty is describing Uber's background coding agent, Minion. The word cut after 'production' is pull requests (PRs), which both transcriptions rendered as 'peers'; he says 'PRs' in the next sentence.

How this was checked

Checked against the source by a first reader, then confirmed independently by a second reader who fetched the source without seeing the first reader's notes (Independent review agent (Claude Sonnet), blind second pass from passage text and citation only, no repository access, 2026-11-07).

Whisper transcript, about 51:00 in the text (no captions.md was provided). The source reads 'So this is our background coding agent. So around 15% of all of the production peers go through minion'. The ellipses cover the omitted 'our' and 'peers', a whisper mishearing of PRs. The 'Once you have for the task…' sentence matches.

And since all the requests go through one place, we could also add like audit logging, session traces, and a whole bunch of infrastructure around this. Every model request at Uber goes through this. So there's no model request that doesn't go through this. So that gives us like one single entry point for across all the models.

So like one, for example, one of the things we did is tagging all of our PRs to different categories, like on complexity level, and is it a feature PR bug fix maintenance testing documentation on different categories. And we could see year over year, how is that mix changing? Luckily, like at least like right now, you can see our percentage of feature PRs is going up, our percentage of maintenance PRs is going down.

So it's been really useful, even in our support channels, I would see like someone reports a bug, the on call ask minion, hey, like, … what is the issue and then minion will come back with, oh, this is the root cause, oh, this looks simple enough, let's just fix it right there and then we would like fix it, like there's no, then loop of like adding it to backlog, doing in the next, next thing, like you're able to fix it right there.

And we have this notion of spend tiers. So by default, you get certain … tier, and then we have many levels of tiers. Once you're close to that tier, then you can raise a request to go to the next tier. And you just need a simple manager approval. … But we don't want to restrict engineers … they should be able to spend whatever they need because ultimately we want to … maximize the gain from this.

right now we still require an engineer to review every PR … goes in. … Once the more confidence we get in our risk scoring and we can also back test it with years of data, right? We have all of this data and the more confidence we have in our AI code reviews, then maybe for some class of low risk PRs, we could enable, we call it green lane like auto landing.
