Skill use in v0.71.0 doesn't work

[aivisbr]

According to the API documentation, following code example I could use to run Agent Skills:

import anthropic

client = anthropic.Anthropic()

response = client.messages.create(
    model="claude-sonnet-4-5-20250929",
    max_tokens=4096,
    betas=["code-execution-2025-08-25", "skills-2025-10-02"],
    container={
        "skills": [
            {
                "type": "anthropic",
                "skill_id": "pptx",
                "version": "latest"
            }
        ]
    },
    messages=[{
        "role": "user",
        "content": "Create a presentation about renewable energy"
    }],
    tools=[{
        "type": "code_execution_20250825",
        "name": "code_execution"
    }]
)

But this code doesn't work in version 0.71.0, because I got a TypeError: "TypeError: Messages.create() got an unexpected keyword argument 'container'". It looks like this version still doesn't fully support Agent Skills. Am I right?

I believe it was released as beta, so it should be called like this

+ response = client.beta.messages.create(
- response = client.messages.create(

Thanks @karpetrosyan - client.beta.messages.create worked for me.

Let's not close this until it gets fixed
