Never Use TaskOutput

TaskOutput floods the main context window with agent transcripts (70k+ tokens).

Rule

NEVER use TaskOutput tool. Use Task tool with synchronous mode instead.

Why TaskOutput reads full agent transcript into context This causes mid-conversation compaction Defeats the purpose of agent context isolation Pattern

WRONG - floods context

Task(run_in_background=true) TaskOutput(task_id="...") // 70k tokens dumped

RIGHT - isolated context, returns summary

Task(run_in_background=false) // Agent runs, returns summary
