…ases Non-Claude models consistently send "agent" or "agent_type" instead of "subagent_type" when calling the task tool, causing repeated Zod validation failures. Accept all three parameter names with a clear precedence order: subagent_type > agent > agent_type. Fixes anomalyco#20804 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Issue for this PR
Fixes #20804
Type of change
What does this PR do?
Non-Claude models (MiniMax, Gemini, Qwen) send
agentoragent_typeinstead ofsubagent_typewhen calling the task tool. Zod rejects these becausesubagent_typeis the only accepted parameter name and it's required. Models retry in a loop (20+ times in my testing) without ever guessing the right name.The fix makes
subagent_typeoptional and addsagentandagent_typeas optional aliases. A new exportedresolveAgentType()function normalizes these to a single value at the top ofexecute()with clear precedence:subagent_type>agent>agent_type. If none are provided, it throws the same error as before.This is the minimal change — one source file and one test mock updated. The resolver is a pure function with no side effects.
