What's Wrong?

Claude keeps crashing when I ask it to stop in the middle of a task.

What Should Happen?

Claude should be able to stop and adjust to me clarifying what I want, this has only started with I assume this latest version update

Error Messages/Logs

Internal error: API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"messages.7.content.3: `tool_use` ids must be unique"},"request_id":"req_011CVnyAb6xg2PwTEZcTJVGA"}

Steps to Reproduce

User

Why do I keep getting this response?

Internal error: API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"messages.7.content.4: tool_use ids must be unique"},"request_id":"req_011CVnxfPVtvxDuz6hfsfCFt"}

Assistant

This error indicates that you're sending duplicate tool_use IDs in a request to the Anthropic API. Each tool use within a message must have a unique ID.

Common causes:

  1. Reusing tool_use blocks - You might be accidentally duplicating a tool call block when constructing the message
  2. Copy-paste errors - Copying an entire tool_use block and forgetting to change/remove the ID
  3. Loop/iteration issues - Code that generates tool calls in a loop might be reusing the same ID
  4. Message construction logic - When building the messages array, you might be including the same tool_use content multiple times

How to debug:

Let me help you investigate. Can you share:

  • The code that's making the API call?
  • Or the file/function where you're constructing the messages array?

I can search your codebase for API calls if you'd like:

**Tool Call: grep "messages.content.tool_use" Status: Completed

No files found

**Tool Call: grep "anthropic.messages.create" Status: Completed

No files found

*Tool Call: grep "tool_use.id" Status: Completed

No files found

Assistant

The searches didn't find obvious API integration code. Could you:

  1. Point me to the file where this error occurs?
  2. Or paste the code snippet that's making the API call?

Once I see the code, I can identify exactly where the duplicate tool_use IDs are being created.

User

You are making the api call, it's a reponse I keep getting when I talk to you

Assistant

Ah! I understand now - this is an error I'm generating when making API calls on your behalf. This is a bug in Claude Code itself.

This error means that when I'm trying to make parallel tool calls (calling multiple tools in a single response), I'm somehow generating duplicate IDs for the tool_use blocks.

Possible workarounds:

  1. Avoid triggering parallel tool calls - Try to phrase requests in a way that only requires one tool at a time
  2. Report the bug - This is definitely a bug in Claude Code that should be reported at https://github.com/anthropics/claude-code/issues

What might be triggering it:

Looking at my previous response, I made 3 parallel Grep calls in a single message. This is likely when the duplicate ID issue occurred.

To help debug this:

  • Does this happen consistently when you ask certain types of questions?
  • Did it just start happening in this conversation, or have you seen it before?
  • Does it occur when I try to call multiple tools at once?

For now, you could try:

  • Asking me to do one thing at a time
  • Restarting the conversation with /clear

This is definitely a bug in Claude Code's tool invocation system that the developers should investigate. Would you like me to help you gather more details to include in a bug report?

User

Ok, so we talked about you clarifying what I wanted first and you didn't do taht. You also tried to make a ts file in my ruby app, so of course I asked you to stop and clarify

Assistant

You're absolutely right - I apologize for that. I should have:

  1. Asked clarifying questions first before making assumptions about what you wanted
  2. Understood your tech stack (Ruby app) instead of assuming TypeScript

This is exactly the kind of situation where I should have used the AskUserQuestion approach or taken time to explore your codebase first to understand the context.

Let me start over properly:

What are you trying to accomplish?

And to better understand your project, let me first check what kind of application this is:
