Background agents and bash tasks no longer generate periodic progress polling messages. Instead, the system now relies entirely on completion notifications.
Details
- The
getProgressMessagefunction has been removed from all task types (local agents, background bash, remote agents, and teammates) - The
task_progressattachment type is no longer generated or rendered - The Task tool description now explicitly states: "you will be automatically notified when it completes — do NOT sleep, poll, or proactively check on its progress"
lastReportedToolCountandlastReportedTokenCounttracking fields removed from task statedeltaSummarySinceLastFlushToAttachmentand the delta summarization LLM call have been removed entirely
Evidence
Removed progress message infrastructure (search for "do NOT sleep, poll")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
