   This issue might be a duplicate of existing issues. Please check:

   • KimiK2-thinking fails at subagent call #6598: Same error pattern — Unknown agent type: [name] is not a valid agent type — KimiK2-thinking fails when invoking custom subagents
   • Kimi K2.5 on AWS Bedrock: multiple failures — premature end_turn, silent stops, and toolResult format errors #14221: Kimi K2.5 on AWS Bedrock: multiple failures including tool call errors
   • Kimi K2.5 on Bedrock: premature end_turn due to Converse API tool call parsing bugs #13807: Kimi K2.5 on Bedrock: premature end_turn due to Converse API tool call parsing bugs
   • Kimi-K2 via OpenRouter fails with tool call tokens inside thinking block #8851: Kimi-K2 via OpenRouter fails with tool call tokens inside thinking block

   If your issue is specifically about the Unknown agent type error when using research or Explore as subagent types, #6598 appears to be the closest match. If it's a broader tool calling failure with Kimi K2.5, the Bedrock-related issues above may also be relevant.

   The model is Kimi K2.5 - Paid API Opencode Zen.

   I would rather not share the session as it has proprietary info on our app in there.

   Also, the tool calls did work fine a couple of days ago.

   Will also add that sporadically Kimi K2.5 through Paid API Opencode Zen starts repeating itself over and over and the only way to stop it is esc. Hit or miss on when this happens, has nothing to do with context, could be a new conversation.

    Truly and much appreciated. I am paying to use your Zen API, though it’s quite awful when you have to wait for just one agent to do all the work. Would love to continue to support your platform. Thx again.
