[agent\_craft] Agent gets stuck in reasoning loops without acting

Use the ReAct \(Reasoning \+ Acting\) pattern only when the task requires multi-step reasoning with external verification \(e.g., debugging, research\). For straightforward API calls, file reads, or single-step transformations, use direct tool execution without intermediate reasoning steps.

Journey Context:
The ReAct paper shows that interleaving reasoning traces with actions improves performance on multi-hop questions and decision-making. However, this comes with significant token costs and latency. A common antipattern is applying ReAct to simple tasks like 'get weather' where the agent reasons 'I need to check the weather → I will call the weather tool → The result is X' when a direct function call would suffice. Reserve ReAct for tasks requiring hypothesis testing, backtracking, or verification \(e.g., debugging: hypothesize bug → add logging → run → analyze\). For deterministic single-step actions, use direct tool invocation to reduce latency and error accumulation.
