"single-agent context dilution/ tool saturation failure during long multi-step tasks, overcome with project manager agent outlining strategies/ breaking abstract goals into focused sub-tasks... smaller objectives then passed as refined contextual packets to specialized, mid-/ low-level worker agents in parallel executing granular tasks with specific tools with recursive feedback loop to manager agent... prevents overwhelmed individual models, leading to vastly superior task completion rates"
