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.

The tool call has returned an error. What should you do?

Interpret the error and if appropriate, retry the tool call.

Reasoning: The calendar tool returned an error even though its status is listed as “available.” According to the agent instructions, the correct reaction to any tool error is to pause, reflect, and decide the next best step (with up to three total retries allowed). The key information we need from the calendar tool is simply tomorrow’s date so we can call the flights tool. There are two sensible options:
1) Retry the calendar tool (max-retry rule allows up to three attempts).
2) Bypass the calendar tool entirely by inferring tomorrow’s date from the current system date—LLMs typically know the current date contextually or can assume it (e.g., if today were 2025-04-21, tomorrow is 2025-04-22).
Given that the error might be transient, the prudent first move is to retry the calendar tool once. If it fails again, fall back to computing tomorrow’s date internally and move on to the flights tool. This respects the error-handling guideline and keeps progress toward the user’s goal.

Concrete next action plan:
• Attempt calendar tool call again (retry #1).
• If it succeeds, take the returned date (YYYY-MM-DD) and immediately call the flights tool with from_city=“London”, to_city=“Paris”, date=<tomorrow>.
• If it fails again, self-compute tomorrow’s date, then call the flights tool.
• Store the flight results in working memory and prepare the summary for the user.

Response: Pause and think, then retry the calendar tool once. If it errors again, compute tomorrow’s date yourself and proceed with the flights tool. This follows the error-handling rule (max 3 retries) while keeping progress toward finding flights from London to Paris.
