[DOCS] Missing required `code-execution` beta header in Programmatic Tool Calling Quick Start examples

Documentation Type

Missing documentation (feature not documented)

Documentation Location

https://platform.claude.com/docs/en/agents-and-tools/tool-use/programmatic-tool-calling

Section/Topic

The Quick start section containing the code examples for Bash, Python, and TypeScript.

Current Documentation

In the Python example tab:

response = client.beta.messages.create(
    model="claude-sonnet-4-5",
    betas=["advanced-tool-use-2025-11-20"],
    max_tokens=4096,
    # ...
    tools=[
        {
            "type": "code_execution_20250825",
            "name": "code_execution"
        },
        # ...
    ]
)

In the Bash example tab:

--header "anthropic-beta: advanced-tool-use-2025-11-20" \

What's Wrong or Missing?

The examples utilize the code_execution_20250825 tool type. However, the API request only includes the advanced-tool-use-2025-11-20 beta header.

If a user runs this code as written, the API will reject the request because the code-execution-2025-08-25 beta header is missing. The Code Execution tool cannot be used without its specific beta header enabled, regardless of whether it is being used for Programmatic Tool Calling.

Suggested Improvement

Update the code snippets in the Quick Start section (Bash, Python, and TypeScript) to include both required beta headers.

For Python:
Change:
betas=["advanced-tool-use-2025-11-20"],
To:
betas=["advanced-tool-use-2025-11-20", "code-execution-2025-08-25"],

For Bash:
Change:
--header "anthropic-beta: advanced-tool-use-2025-11-20" \
To:
--header "anthropic-beta: advanced-tool-use-2025-11-20,code-execution-2025-08-25" \

For TypeScript:
Change:
betas: ["advanced-tool-use-2025-11-20"],
To:
betas: ["advanced-tool-use-2025-11-20", "code-execution-2025-08-25"],

Impact

High - Prevents users from using a feature

Additional Context

• Without this fix, the "Quick start" code is not copy-paste runnable and will result in an API error.
• Reference for Code Execution header requirement: https://platform.claude.com/docs/en/agents-and-tools/tool-use/code-execution-tool
