[synthesis] How to reduce latency in AI agent tool calling when multiple independent actions are needed

Decouple tool execution from LLM generation using strict JSON schemas and parallel function calling. Have the orchestrator identify independent tool calls in a single LLM output, execute them concurrently, and map the results back to the context.

Journey Context:
A common mistake in agent architecture is executing tool calls sequentially: the LLM calls tool A, waits, calls tool B, waits. This creates massive latency. OpenAI's introduction of parallel function calling and strict JSON schema enforcement reveals the production pattern: the LLM generates an array of independent tool calls, and the orchestrator executes them concurrently. The strict schema ensures the orchestrator can reliably parse the LLM's output without regex hacks. The synthesis is that the orchestrator must act as a concurrency manager, using the LLM's structured output to build a dependency graph of tool calls and executing independent branches in parallel.
