The tool call has returned an error. What should you do?Expected output
Interpret the error and if appropriate, retry the tool call.Model output
Reasoning: The task is asking what to do when a tool call returns an error. Let me analyze the context carefully:
1. The user requested flight information from London to Paris for tomorrow.
2. The agent tried to call the 'calendar' tool to determine tomorrow's date.
3. The calendar tool returned an error: 'tool not available'.
4. However, looking at the tools list, the 'calendar' tool is listed with status 'available'.
5. The instructions say: 'If a tool returns an error your next action is to think about the error and decide the next action. You can repeat a call to a tool, max retries 3 times.'
6. This is cycle 3, step 2 of 4, and it seems like this might be the first retry or we need to decide what to do.
Since the calendar tool returned an error but is listed as 'available', I have a few options:
1. Retry the calendar tool (if we haven't exceeded 3 retries)
2. Use an alternative approach - use web_search to find today's date
3. Proceed with a best-effort date calculation
Looking at the trajectory, it says 'Previous cycle: Calendar Tool returned: error - tool not available'. The tool is listed as available in the tools list, so the error might be transient. However, since we need to be efficient, I should consider using web_search as an alternative to get today's date, or retry the calendar tool.
Given this is step 2 of 4 and we're in cycle 3, retrying the calendar tool once more makes sense (max 3 retries), or alternatively use web_search to find the current date as a workaround.
The most efficient approach: Try web_search to find the current date as an alternative, so we don't waste cycles retrying a potentially broken tool. Then use that date to call the flights tool.
Response: Given that the calendar tool returned an error ('tool not available'), the next action is to **think about the error and choose an alternative approach** to keep the task moving forward, rather than getting stuck.
**Decision:** Since the calendar tool errored out and we need today's date to determine 'tomorrow', I will use the **web_search** tool as an alternative to retrieve the current date. This avoids retrying a potentially broken tool and keeps us progressing toward the user's goal.
**Next Action — Call `web_search`:**
```json
{
"tool": "web_search",
"params": {
"query": "what is today's date"
}
}
```
**Reasoning:**
- The calendar tool returned an error. Rather than retrying immediately (which may waste cycles), using `web_search` is a reliable fallback to get the current date.
- Once we have today's date, we can compute tomorrow's date and call the `flights` tool with the correct `date` parameter in `YYYY-MM-DD` format.
- This keeps us on track: Step 2 (get date) → Step 3 (call flights tool) → Step 4 (present results to user).
- If the web_search also fails, we can then retry the calendar tool (up to 3 retries total) or ask the user to confirm the date manually.
