Invalild tool + execution aborted

[yoobi]

Description

I am using auggie ACP with opencode because auggie is not yet in the provider list (I already made a request for that #10216).
Overall it is working correctly but recently I got this issue after a prompt. Not sure how to qualify it

⚙ invalid [tool=acp.acp_provider_agent_dynamic_tool, error=Model tried to call unavailable tool 'acp.acp_provider_agent_dynamic_tool'. Available tools: invalid, read, glob, grep, task, webfetch, todowrite, todoread, skill.]

Steps to reproduce

1. Add auggie as acp (maybe it'll do the same with other acp)
2. I have an agent such as (not sure if it is because of the agent or not)

  edit: false
  read: true

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

• Why does opencode frequently encounter tool calling errors when using claude. #9532: Why does opencode frequently encounter tool calling errors when using claude. - Same error pattern: 'Model tried to call unavailable tool' errors suggesting the model is being given tools that are not available in the ACP environment

Feel free to ignore if this doesn't match your specific case.

I used glm5 in aisp and moore, also had this problem. But glm4.7 is all right.
