roles must alternate between "user" and "assistant" error and rate limit

[kpoxo6op]

Hey I have experienced #18 too and I can reproduce it using the latest anthropic-sdk-python v0.30.0.

I have a suspicion that hitting the rate limit may cause 'found multiple "user" roles' error.

Reproducing the issue involves hitting the rate limit so it can be "resolved" magically. It also make it hard to debug and reproduce as we may hit the limit at arbitrary time.

Here is my closest attempt. I have hit the rate limit already, so the first message is rate_limit_error.

Replaced Sonnet with Haiku to work around the rate limit and tried again - everything worked fine:

Claude: Okay, let's create a new Python project structure for a web application. Here's what I'll do:

<thinking>
To create a new Python project structure for a web application, I will use the create_folder and create_file tools. The required parameters are:
- path (string): The path where the folder/file should be created
The optional parameter is:
- content (string): The initial content of the file (only for create_file)

I have all the required information to complete this request, so I can proceed with the tool calls.
</thinking>

Tool Used: create_folder
Tool Input: {'path': 'my-web-app'}
Tool Result: Folder created: my-web-app

Claude: <thinking>
To create a Python project structure for a web application, I will need to create the following folders and files:

1. Root folder: 'my-web-app'
2. Subfolders:
   - 'app': Contains the main application code
   - 'templates': Contains HTML templates for the web pages
   - 'static': Contains static files like CSS, JavaScript, and images
   - 'tests': Contains unit tests for the application
3. Files:
   - 'app/__init__.py': This makes the 'app' folder a Python module
   - 'app/main.py': The main entry point of the application
   - 'requirements.txt': Lists the required Python packages for the project
   - 'README.md': Provides information about the project
</thinking>

Update your Anthropic package

[kpoxo6op]

Looks like I removed pip output accidentally, I am using v0.30.0 https://pypi.org/project/anthropic/

Which version do I need to update to?
