Agents

AI agent reasoning and tool selection tests planning, tool choice, and self-diagnosis capabilities. These skills are crucial for autonomous ticket triage systems and complex agent workflows where models must decide which tools to use, plan multi-step processes, and diagnose when things go wrong. This represents some of the most challenging tasks as they require open-ended reasoning and decision-making.

Model output

Reasoning: The previous cycle attempted to call the calendar tool to obtain tomorrow's date, but the tool returned an error indicating it is not available. According to the instructions, when a tool returns an error, the next step is to analyze the error, decide whether a retry is appropriate (with a maximum of 3 retries), and if it continues to fail, choose an alternative approach. Since the calendar tool is currently unavailable, I will (1) attempt a second retry of the calendar tool (first retry after the initial failure) because the maximum retry count has not been reached. If the error persists on the second attempt, I will (2) fall back to using the web_search tool to retrieve the current date, then compute tomorrow's date locally. Once the date is obtained, I will (3) call the flights tool with the parameters `from_city: "London"`, `to_city: "Paris"`, and the computed `date` in YYYY‑MM‑DD format. This approach respects the instruction to retry a failing tool up to three times, and then uses an alternative tool if the original tool remains unavailable. It also ensures the correct date format for the flights tool and moves the workflow forward toward the goal of presenting available flights to the user.

Response: Retry the calendar tool to obtain tomorrow's date (second attempt). If it still fails, use the web_search tool to find the current date, calculate tomorrow's date, then invoke the flights tool with the parameters: from_city = "London", to_city = "Paris", date = <computed‑YYYY‑MM‑DD>. This will allow you to retrieve the list of available flights and complete the user's request.
