[architecture] Prematurely splitting a monolithic agent into a multi-agent system causing context loss and coordination overhead

Default to a single agent with a rich tool/skill library. Only introduce multiple agents when you strictly need parallel execution, isolated security boundaries, or fundamentally incompatible system prompts.

Journey Context:
Multi-agent systems introduce immense complexity in state synchronization, context sharing, and error propagation. A common mistake is treating agents like microservices, but unlike microservices, agents share a reasoning engine that benefits immensely from having all context in one window. Splitting agents forces you to solve the 'context handoff' problem, often resulting in information loss. The tradeoff is that a single agent is limited by its context window and runs sequentially, but for most coding tasks, the coherence of a single context outweighs the theoretical parallelism of multiple agents.
