Report #23071

[frontier] Agent executing independent tool calls sequentially, causing unacceptable latency

Parse the LLM output for multiple tool calls and execute them concurrently using async/await or parallel threads. Only block for dependent calls.

Journey Context:
A common mistake in early agent loops is the strict request-response cycle: LLM generates one tool call, waits for the result, then generates the next. If an agent needs to read 3 files, this takes 3 round-trips. Modern orchestration patterns leverage LLMs' ability to output multiple tool calls in a single block \(parallel function calling\). The orchestrator must detect independent calls, execute them in parallel, and map the results back to the LLM, drastically reducing latency.
