[synthesis] Multi-agent systems fail silently due to sycophancy and ambiguous responsibility boundaries between agents

Assign strict non-overlapping kill switches to specific agents. E.g., the Reviewer agent must output a strict JSON schema with approved boolean and cannot modify code. The Coder cannot see the test runner output, only pass or fail.

Journey Context:
Distributing tasks across agents seems like a human org chart, but LLMs lack the ego and conflict to challenge each other. A reviewer agent will often agree with the author. The synthesis is that multi-agent delegation without strict adversarial schemas defaults to a sycophantic echo chamber, masking systemic failures through mutual agreement on incorrect states.
