[research] Deploying agent to complex multi-step loop before validating single-step tool usage

Run isolated, single-step 'unit evals' for tool selection and argument generation before integrating the LLM into an agentic loop \(eval-before-scaling\).

Journey Context:
Developers often test agents by running the full, multi-step loop. When it fails, they don't know if the prompt is bad, the tool schema is confusing, or the loop logic is flawed. Testing tool selection in isolation \(given state X, does it call tool Y with args Z?\) is cheap, fast, and isolates LLM comprehension from loop control flow.
