[frontier] Single-agent context windows overflow when handling complex research-to-code workflows

Use Anthropic's cookbook pattern of specialized sub-agents \(Triage, Research, Coding\) with explicit message passing via tool results rather than shared state

Journey Context:
Monolithic agents fail at complex workflows because they mix concerns \(researching APIs, writing code, checking style\) causing context pollution. Anthropic's 2025 multi-agent patterns advocate for strict role separation where each agent has a narrow system prompt and toolset. The critical architectural decision is avoiding shared mutable state; instead, Agent A \(Research\) terminates with a structured output that Agent B \(Coding\) receives as a fresh user message. This prevents 'identity confusion' where agents forget which role they're playing. The pattern requires careful design of the handoff schema to ensure critical context isn't lost, but scales better than single-agent approaches. It differs from LangGraph's state machines by being stateless between transitions, which reduces side-effect bugs.
