TL;DR

The issue is likely caused by the _strip_blocked_tools function removing the "delegation" toolset, which is necessary for sub-agents to dispatch grandchild agents, and a workaround may involve modifying this function to allow the "delegation" toolset when MAX_DEPTH=2.

Guidance

• Review the _strip_blocked_tools function to understand why it removes the "delegation" toolset and consider modifying it to exempt this toolset when MAX_DEPTH=2.
• Investigate the MAX_DEPTH setting and its relationship with the "delegation" toolset to determine if there's a configuration change that can resolve the issue.
• Check the blocked_toolset_names set in the _strip_blocked_tools function to see if it can be modified to not include "delegation" under certain conditions.
• Consider adding a conditional statement to the _strip_blocked_tools function to handle the "delegation" toolset differently when MAX_DEPTH=2.

Notes

The issue seems to be related to the interaction between the _strip_blocked_tools function and the MAX_DEPTH setting, but without more information about the desired behavior and the context in which this code is deployed, it's difficult to provide a more specific solution.

Recommendation

Apply workaround: Modify the _strip_blocked_tools function to conditionally allow the "delegation" toolset when MAX_DEPTH=2, as this seems to be the most direct way to address the issue described.
