Report #13376

[architecture] Multi-agent systems making N sequential tool calls for a batch operation instead of one aggregated call, causing extreme latency

Provide agents with batch-capable tools and explicitly instruct them in their system prompt to aggregate operations, rather than looping over individual items.

Journey Context:
LLMs naturally think step-by-step. If an agent needs to update 10 files, it will often invoke a write\_file tool 10 times sequentially. In a multi-agent setup, this latency is compounded. By providing a write\_files\_batch tool and prompting the agent to use it, you collapse N round-trips into 1. The tradeoff is that batch tools are less flexible, but the latency reduction is critical for orchestration.
