Report #38480

[architecture] Prematurely splitting a monolithic agent into multiple coordinating agents, causing exponential context-switching overhead

Start with a single agent equipped with a robust skill/tool library. Only split into multi-agent when context window limits are hit or distinct, isolated permission boundaries are required.

Journey Context:
Multi-agent architectures are often chosen for aesthetic or organizational reasons rather than technical necessity. Every agent-to-agent handoff introduces a context window boundary where information is lost or must be explicitly summarized. A single agent with all context makes better holistic decisions. Multi-agent is only justified when the task is genuinely parallelizable, requires isolated system prompts, or needs distinct credential scopes.
