Report #40443

[synthesis] Final agent in a multi-agent swarm makes suboptimal decisions due to truncated history

Instrument the token count of the task payload at each agent handoff. Alert when the payload approaches the context window limit of the receiving agent, forcing truncation.

Journey Context:
In multi-agent systems, agents pass accumulating context \(previous steps, tool outputs\) to the next agent. If intermediate agents are verbose, the final agent receives a payload that hits its context limit. The framework silently truncates the prompt \(often dropping the original user goal at the top\). The final agent executes a valid but misaligned action. Monitoring individual agent token usage doesn't catch this; you must monitor the handed-off payload size, combining multi-agent orchestration observability with context window mechanics.
