[architecture] When to use multiple agents vs a single agent with a skill library

Default to a single agent with tools/skills. Only introduce multiple agents if you need isolated context windows, distinct system prompts, or parallel execution of independent tasks.

Journey Context:
Developers often over-decompose tasks into multiple agents, mimicking human organizational charts. This introduces routing errors, context loss during handoffs, and latency. A single agent with a well-defined tool suite maintains a unified context, avoiding the telephone game of state passing. Multi-agent is only justified when the context required for one sub-task would overwhelm the primary agent's window, or when strict permission boundaries \(e.g., read-only vs. write-only\) are needed.
