Report #85306

[architecture] Prematurely splitting a monolithic agent into multiple agents causing context fragmentation and orchestration overhead

Default to a single agent with a robust skill/tool library; only split into multiple agents when context windows overflow, distinct system prompts are strictly required, or security/trust boundaries mandate isolation.

Journey Context:
The 'more agents = better' fallacy leads to complex orchestrators, lost shared context, and brittle handoffs. A single agent maintains a unified context window and can seamlessly chain tools. Splitting is only justified when the cognitive load \(prompt complexity\) exceeds a single model's capacity, or when you need strict permission isolation \(e.g., a 'planner' that cannot execute code vs an 'executor' that can\).
