fix: crash when sending tool_result with anthropic and google #34

miyamo2 · 2025-04-23T23:30:43Z

v0.7.0 does not work properly when using the anthropic model or google model.
This is because the role must be user to send a content block containing a tool_result type in anthropic and google.

Continue the conversation by sending a new message with the role of user, and a content block containing the tool_result type and the following information:

https://docs.anthropic.com/en/docs/tool-use.

Also, there are only user and model roles in gemini, and tool does not seem to exist.

role string
Optional. The producer of the content. Must be either 'user' or 'model'.

Thank you.

In v0.7.0

  I'll search to find out what MCP stands for using Brave's web search, since this could have multiple meanings depending on the context.

  Assistant:


  Based on the search results, MCP can stand for several different things depending on the context:

  1. Model Context Protocol - A recent open standard designed by Anthropic to help AI assistants interact with data and tools
  2. Microsoft Certified Professional - A certification from Microsoft
  3. Microsoft Certified Partner - An independent company providing Microsoft-related products or services
  4. Male Chauvinist Pig (informal, derogatory)
  5. Master Control Program (in computing contexts)

  Given that you're asking this question in the context of the available tools which include "mcp-restaurant-order", it's most likely referring to "Model Context Protocol" which is the system
  that
  enables AI assistants to interact with external tools and services, like the restaurant ordering system we have access to.

I've tested setting the role to "user" and that works as well (using a corporate wrapper service around Azure OpenAI). So perhaps it's fine to change it to "user" for all providers?

miyamo2 · 2025-04-24T06:15:04Z

So perhaps it's fine to change it to "user" for all providers?

First, the original role:user was changed to role:tool in the v0.7.0 release.
Wasn't this changed with an intention?

cmd/root.go

It was changed by my commit, as that's the recommendation for the wrapper service I'm using. Since OpenAI is blocked in my network (even the website and documentation 🤦) I can't verify whether OpenAI is recommending it as well.

But I've just checked that it works fine with role = user for me, so likely it isn't required.

miyamo2 · 2025-04-24T21:27:19Z

There are only user and model roles in gemini, and tool does not seem to exist.

role string
Optional. The producer of the content. Must be either 'user' or 'model'.

https://ai.google.dev/api/caching?authuser=5&hl=en#Content

Also, OpenAI chat completion only defines 3 roles.

user
developper(system)
assistant

https://platform.openai.com/docs/api-reference/chat/create

However, there seems to be a tool role in ollama.

role: the role of the message, either system, user, assistant, or tool

Anyway, I could be sure: Google crash too.
