🟡 Medium Layers/OpenCodeAdapter.ts:2245
A related child session.updated overwrites the parent thread name with the sub-agent's title. The broadened routing lets the event reach openCodeEventSessionTitle(event) and emit thread.metadata.updated for context.session.threadId; only run that title mirror when isParentEvent is true.

A related child `session.updated` overwrites the parent thread name with the sub-agent's title. The broadened routing lets the event reach `openCodeEventSessionTitle(event)` and emit `thread.metadata.updated` for `context.session.threadId`; only run that title mirror when `isParentEvent` is true.
ApprovabilityVerdict: Would Approve Macroscope's review found this PR approvable — This is a focused OpenCode adapter bug fix that maps existing child-session events into the established Agents panel lifecycle and leaves execution, schemas, and deployment behavior unchanged. A remaining risk is that child session updates can currently mirror a child title onto the parent thread name. Not approved because:

first completion, skip subsequent terminal events without deleting

Thanks for the PR. We're not taking changes to the orchestration and provider layers right now: that part of the server is being rewritten for V2, and merging into the current code would either conflict with or be thrown away by that work. Closing for now. If this is still an issue once V2 lands, please reopen (or open a fresh PR against the new code) and we'll take a proper look. |
OpenCode reports spawned sub-agents as child sessions, but the adapter only forwarded their tool and request events. Because it did not emit the shared task lifecycle events, the Agents panel had no roster entries and the activity appeared only in the chat.
Translate related child-session create, update, and delete events into task lifecycle events. This lets the existing Agents panel show OpenCode sub-agents with their title and running/completed state without changing the chat timeline behavior.
Includes focused OpenCode adapter coverage; all 110 adapter tests pass.
