TL;DR

The research subagents are getting stuck due to invalid request errors and safety restrictions when trying to access certain domains, such as 'reddit.com', which is blocked by the user agent.

Guidance

• The errors indicate that the subagents are trying to access domains that are not allowed due to safety restrictions or are blocked by the site owners.
• The invalid_request_error messages suggest that the request to 'reddit.com' is being blocked, and the McpToolCallError message indicates a safety restriction.
• To mitigate this issue, consider configuring the subagents to avoid accessing blocked domains or to use a different user agent that is allowed to access these domains.
• Review the support article linked in the error message (https://support.anthropic.com/en/articles/8896518-does-anthropic-crawl-data-from-the-web-and-how-can-site-owners-block-the-crawler) for more information on how to handle blocked domains.

Example

No code snippet is provided as the issue is related to configuration and domain access rather than code.

Notes

The provided information is truncated, and the full error log may contain additional details that could help diagnose the issue. The solution may require adjustments to the subagents' configuration or the user agent used to access the domains.

Recommendation

Apply a workaround by configuring the subagents to avoid accessing blocked domains or using a different user agent. This is because the issue is related to safety restrictions and blocked domains, and a workaround can help mitigate the problem until a more permanent solution is found.
