Product Delivery

TL;DR

I helped ship Copilot agent sessions in GitHub Mobile as a cross-platform workflow people could actually use away from their desk. The public surface was the refreshed Copilot tab, session list, native session logs, and in-app follow-up actions. My part lived in the production stretch, in implementation review, cross-platform coherence, and the details that make an agent workflow trustworthy on mobile.

GitHub Mobile: Agent sessions without leaving the app

Publicly, this shipped as a refreshed Copilot tab and native session logs in GitHub Mobile. The product problem was simple to say and hard to get right. People needed to track agentic work, inspect what happened, and take the next action without leaving the app.

Another designer led much of the initiative. I came in where shipped work usually gets harder, around cross-platform coherence, production behavior, edge cases, and the question of whether the experience still made sense once it was real.

The hard part was the handoff

Agentic workflows create a strange handoff. The work is happening somewhere else, but the user still needs to understand progress, state, output, and what to do next.

On mobile, that means the product has to be clear under interruption. A session may be running, completed, blocked, or ready for review. The user may only have a minute. The interface has to answer the obvious questions quickly. What changed, is it still running, and can I act on it?

I focused on the parts where the workflow had to feel native, legible, and reliable under pressure, not merely aligned with a mockup.

Designing across iOS and Android

iOS and Android shouldn't feel identical, but they should still feel like the same product. A lot of cross-platform design work lives in that gap.

I helped keep the experience consistent at the product level while still respecting each platform. The Copilot tab, session list, logs, and follow-up actions needed the same mental model across both apps. The interaction details could still behave like native mobile UI.

Working inside production details

Much of my contribution happened close to implementation. I reviewed production changes, caught issues that only show up once the experience is running, and made focused code changes where that helped unblock the work.

I care most about this part of the work. Once the feature exists in code, you can see whether the state filters actually make sense, whether session logs stay readable, whether loading and empty states explain enough, and whether the product still communicates the right thing under pressure.

What had to hold up

My focus wasn't adding more surface area. It was protecting the value of the workflow as it moved through production.

The experience needed clear hierarchy, sensible defaults, resilient states, and enough platform detail to feel like part of GitHub Mobile instead of a feature placed on top of it.

It also helped clarify what GitHub Mobile can own in an agentic workflow. The app doesn't need to become the whole development environment. But it can help people track progress, review outcomes, and take the next step from wherever they are.

Closing

For agent workflows on mobile, the next step has to be clear.

Shipping this was crucial, but my part was making the workflow clear enough that people could trust it on a phone without turning the phone into a worse version of github.com.
