[research] Impossible to tell if an agent failed due to a bad plan or a bad tool execution

Split evals into two phases: 1\) 'Plan eval' \(given the state, did the agent choose the right next tool?\), 2\) 'Execution eval' \(given the tool output, did the agent parse it correctly?\).

Journey Context:
Treating agent runs as a single black box makes debugging a nightmare. If an agent calls the wrong API, it's a planning failure. If it calls the right API but ignores the error message, it's an execution/reasoning failure. Separating these in your eval suite allows you to target prompt fixes precisely—either fixing the system prompt \(planning\) or the few-shot examples \(execution\).
