 ### Notes on behavior
 
 - The new session keeps the fresh prompt as its user-turn text and immediately starts working. On-disk state (git status, staged or uncommitted changes) carries over because it is the same project directory.
-- By default the original session is left running and its full transcript remains in the session tree — the clean context lives in the child session. The handoff prompt includes the parent session ID so both you and the model know where to read the earlier conversation.
-- `abort_current: true` freezes the original session after the new one is started. Because abort cancels the current agent turn, the tool's returned text may not be delivered to the old session — the side effects (create + prompt) complete first.
+- The original session is always left running and its full transcript remains in the session tree — the clean context lives in the child session. The handoff prompt includes the parent session ID so both you and the model know where to read the earlier conversation.
 - `disable_compaction_continue` (default `true`) rejects the synthetic "continue" turn opencode would append after a compaction, so a compaction that does slip through never silently continues. Set it to `false` to keep stock behavior.
