Report #93048

[synthesis] Parse free-form LLM text output to determine agent actions and extract structured parameters

Use native tool calling / function calling APIs as the primary agent loop primitive. Define tools with typed JSON schemas, let the model return structured tool invocations, and route execution through a tool dispatcher. Never parse action intent from unstructured text.

Journey Context:
Early agent frameworks \(original ReAct implementations, early AutoGPT\) parsed actions from free-form text output using regex or string matching. This is fragile—models vary output format, edge cases break parsers, and there's no type safety. The industry has converged on native tool calling APIs \(OpenAI function calling, Anthropic tool use\) as the architectural primitive. This convergence is visible across every major AI product: Cursor's tool use for file operations, Perplexity's structured search invocation, v0's component generation with typed parameters. The key insight from cross-referencing these products: tool calling APIs provide a structured, typed, parseable output format specifically trained for action invocation, eliminating an entire class of parsing errors. The tradeoff is tighter coupling to specific model providers' APIs, but the reliability gain is overwhelming. If you need model portability, abstract the tool-calling interface behind a provider-agnostic layer rather than falling back to text parsing. The OpenAI Swarm framework codifies this pattern explicitly.
