[architecture] Context fragmentation and loss of coherence when splitting a complex coding task across multiple agents

Default to a single agent with a rich tool/skill library. Only graduate to multi-agent when tasks require fundamentally conflicting system prompts, isolated permissions, or exceed context window limits.

Journey Context:
Multi-agent is often over-engineered for coding. Every inter-agent message costs tokens and loses nuance. A single agent maintains the entire mental model of the codebase in one context window. Multi-agent is only justified by hard boundaries \(e.g., a planner vs an executor with restricted file-write permissions\), not just to divide and conquer a monolithic task.
