[frontier] Monolithic agent becomes unreliable as it accumulates state and context across many subtasks

Decompose the agent into a lightweight orchestrator that spawns ephemeral, single-purpose micro-agents for each subtask. Each micro-agent gets a focused prompt, minimal context, and a single tool set. It executes, returns a result, and is destroyed. The orchestrator manages the overall workflow and aggregates results.

Journey Context:
Monolithic agents that handle everything in one long conversation accumulate state, confuse their context window with unrelated task history, and become increasingly unreliable as the session grows. The swarm pattern \(demonstrated in OpenAI's Swarm framework\) decomposes work into ephemeral micro-agents. Each micro-agent is: \(1\) single-purpose with a focused system prompt, \(2\) given only the context it needs \(not the entire conversation\), \(3\) equipped with only relevant tools \(reducing confusion\), \(4\) destroyed after completing its task \(no state accumulation\). The orchestrator is a thin routing layer that hands off between agents. Tradeoff: more LLM calls total \(each handoff is a new conversation\), and the orchestrator must serialize context between agents. But the reliability gain is dramatic: each micro-agent operates in a clean, focused context window, dramatically reducing hallucination and confusion. This pattern is winning in production because reliability scales while monolithic agent reliability degrades.
