Report #55158

[agent\_craft] Agent latency is high because it waits for file reads and searches to complete sequentially

For independent tool calls \(file reads, grep, ls\), explicitly instruct the model to use parallel\_tool\_calls \(OpenAI\) or parallel tool\_use blocks; structure the system prompt to recognize tool independence \(e.g., 'If you need multiple files, request them all at once'\)

Journey Context:
By default, agent frameworks often implement a while loop: think -> call tool -> wait -> think again. This serializes independent operations. If the agent needs to read 3 files to understand a bug, doing this sequentially adds 3x latency. Modern APIs \(OpenAI's parallel\_tool\_calls parameter, Anthropic's tool\_use\) support batched tool calls in a single response. However, the model won't use this unless the system prompt explicitly primes it to batch independent requests. The tradeoff is complexity in handling the results \(all come back at once\), but for latency-critical agents, this is essential.
