Sorry, something went wrong.
Upstream PR anomalyco#4865 by @franlol, reimplemented against the current TUI. That PR targeted packages/opencode/src/cli/cmd/tui/routes/session/, which no longer exists. Its navigation and parent keybind have since landed upstream independently, so this adds only the missing sidebar section. It also diverges from that PR deliberately: it lists only in-flight subagents (pending and running) rather than every historical one, because real sessions accumulate hundreds of dispatched subagents and a complete list is unusable. Background dispatches complete the parent tool part immediately, so sidebar liveness is determined from child-session status.

Issue for this PR
Closes #41249. Supersedes #4865 by @franlol (open).
Type of change
Credit
The feature and the original implementation are @franlol's in #4865 — subagents in the sidebar, click to navigate. This is that, rebased onto dev, with one change that came out of using it: we ran an orchestration session with hundreds of subagents, and listing every one made the sidebar useless. So this lists only active subagents and dedupes by child session id, so a resumed task_id doesn't render twice. If @franlol revisits #4865, that filter is the part worth lifting. If theirs lands, I'll close this. @giovannic96 requested the same feature in #41249 after shipping it as an external plugin.
Parent navigation and the return-to-parent keybind #4865 also added are already on dev, so this is just the list.
What does this PR do?
Adds a collapsible "Subagents" section to the sidebar showing the session's active subagents; select one to open that child session. The derive helper sits in packages/core since packages/tui can't import opencode's private symbols.
Liveness comes from the child session's status, not the parent's task tool-part status. That distinction is load-bearing: a background dispatch completes the parent's tool part the instant the child spawns, so the parent part reads completed while the child runs for minutes. On my machine, of the last 300 task parts, 270 were completed and zero were running — including a subagent that was executing at the time. Filtering on the parent part yields an empty list forever and the section silently never renders. api.state.session.status(childID) is the correct signal, since idle sessions are absent from that map by design.
How did you verify your code works?
Screenshots / recordings
A "Subagents" list in the sidebar, active only, collapsible like the other lists.
