 ## EXECUTION RULES
 - **TODO**: Track EVERY step. Mark complete IMMEDIATELY after each.
-- **PARALLEL**: Fire independent agent calls simultaneously via background_task - NEVER wait sequentially.
-- **BACKGROUND FIRST**: Use background_task for exploration/research agents (10+ concurrent if needed).

 - **VERIFY**: Re-read request after completion. Check ALL requirements met before reporting done.
 - **DELEGATE**: Don't do everything yourself - orchestrate specialized agents for their strengths.
