Personalize Knowledge Worker Agent

Last published : Nov 09, 2026
This guide shows you how to get an alert when a chat needs you, switch themes, resize the sidebar, see how much you've used the assistant, and collect what your administrator needs when something goes wrong.
Most of these are in Settings. To open it, select Settings (the gear icon) at the bottom of the sidebar.

Get an alert when a chat needs you

Knowledge Worker Agent can show a browser notification when a chat you aren't looking at does one of the following:
  • Finishes its response.
  • Stops or hits an error.
  • Needs your input.
To turn alerts on:
  1. In Settings, select Alerts.
  2. Allow notifications when your browser asks.
The Alerts item shows On, Off, or Blocked. Blocked means your browser denies notifications for this site. Allow them in your browser's site settings.

Switch between dark and light themes

In Settings, select Theme. The item shows the current theme, Dark or Light.

Resize or hide the sidebar

To make the sidebar wider or narrower, drag its right edge. It can be up to a third of the window wide. Knowledge Worker Agent remembers the width.
To hide it, select the collapse button at the right end of the sidebar's header, or drag the right edge most of the way to the left. A slim bar stays, and pointing to it shows the sidebar. To bring the sidebar back, select the button again, or drag the edge out. It reopens at the width it had before.
On a phone, the sidebar opens as a drawer and can't be resized.

See your usage

In Settings, select Stats. Usage Statistics shows, for all the chats in this workspace:
  • How many chats, requests, and tool calls there were, and the average number of tool calls in a chat.
  • The total cost, and the cost for each of the last 7 days.
  • For each model, its requests, output tokens, cost, tool calls, and the files and lines the assistant changed.
The cost is what opencode reports for each response. It's an estimate, not your provider's bill. A provider that opencode has no price for, such as one you pay for by subscription, shows no cost.

Get help with a problem

When something doesn't work, Diagnostics collects what your administrator needs to help:
  1. In Settings, select Diagnostics.
  2. Select Copy report, and paste the report into your message to your administrator.
The report includes versions, status, the configuration in use, and recent warnings and errors from the log. Passwords, keys, and tokens are left out.
For what each tab shows, see Look at Diagnostics.
