Report #53485

[agent\_craft] Agent makes sequential tool calls for independent operations, causing unnecessary latency

Implement parallel tool dispatch: analyze the dependency graph of required information; if tools have no data dependencies \(e.g., reading two different files\), batch them in a single LLM call using the API's multi-tool invocation feature.

Journey Context:
Naive ReAct \(Reasoning \+ Acting\) loops generate one thought, call one tool, wait, get result, repeat. This is slow for tasks like 'read config.json and read package.json to compare versions.' The correct pattern is to request both reads in parallel. Modern APIs \(OpenAI, Anthropic\) support passing multiple tool calls in one response. The agent framework should: \(1\) Parse the LLM's plan to identify independent operations, \(2\) Allow the LLM to emit multiple tool\_use blocks in one turn, \(3\) Execute them concurrently, \(4\) Return results in a single message with multiple tool\_result blocks. This cuts latency from O\(n\) to roughly O\(1\) for independent operations. Tradeoff: Complexity in error handling \(what if one of 5 parallel calls fails?\). Alternative: Sequential is simpler to debug but unacceptable for latency-sensitive tools.
