Repository navigation
when experimental.subagent_depth > 1, the GUI navigation breadcrumb breaks into additional tabs. #48515
Description
Description
I have been doing a lot of orchestration work in OpenCode v2 lately, and I have been experimenting with increasing the experimental.subagent_depth to values bigger than 1.
The engine works well and it seems correct.
The GUI however, gets lost when I start clicking the subagent cards when I want to inspect what they are doing.
The way it breaks is that for root-level and level-1, the breadcrumb correctly shows parent and child names in the breadcrumb bar; when I click a subagent at level-1, then instead of the breadcrumb bar correctly updating, it opens a new tab.
One additional information, I am using web mode with sidebar (instead of top tabs).
Plugins
None
OpenCode version
v0.0.0-beta-19425
Steps to reproduce
- Customize
opencode.jsonwithexperimental.subagent_depth > 1 - Create an architecture of subagents in such a way that you got at least 2 levels deep.
- Start and navigate until you decide to open a second-level deep agent for inspection.
- New tab shows up.

Thanks for the report! Nested subagents now stay grouped under the original session tab and show their full breadcrumb path, first released in 2.0.17. Update with
opencode upgradeornpm i -g @opencode/cli@latest(desktop: update the app). Please reopen or comment if navigating deeper subagents still creates extra tabs on that version.
