Report #8237

[architecture] Prematurely splitting a system into multiple agents, causing context fragmentation and routing failures

Start with a single agent equipped with a skill library \(tools\). Only graduate to a multi-agent architecture when you hit context window limits, need fundamentally different system prompts/personas, or require parallel execution.

Journey Context:
'Multi-agent' sounds sophisticated, but routing a task to the right agent is itself an LLM call that can fail. Every handoff loses nuance and context. A single agent with well-defined tools maintains full conversational context and avoids routing errors. Multi-agent is only justified when the system prompts conflict \(e.g., a strict code reviewer vs a creative code writer\) or when tasks must run in parallel to save time.
