[DOCS] Skills guide examples include unnecessary prompt-caching-2024-07-31 beta header

Documentation Type

Incorrect/outdated documentation

Section/Topic

Code examples throughout the Skills guide that include beta headers

Current Documentation

Multiple code examples include the prompt caching beta header:

``python betas=["code-execution-2025-08-25", "skills-2025-10-02", "prompt-caching-2024-07-31"], ``

``typescript betas: ['code-execution-2025-08-25', 'skills-2025-10-02', 'prompt-caching-2024-07-31'], ``

``bash -H "anthropic-beta: code-execution-2025-08-25,skills-2025-10-02,prompt-caching-2024-07-31" \ ``

What's Wrong or Missing?

The prompt-caching-2024-07-31 beta header is no longer needed. The prompt caching documentation explicitly states:

"Prompt caching is now generally available, so you no longer need the beta prefix."

The API release notes confirm:

"The 1-hour cache duration for prompt caching is now generally available. You can now use the extended cache TTL without a beta header."

Including this deprecated beta header in examples may confuse developers who wonder why it's present, or cause them to unnecessarily include it in their own code.

Suggested Improvement

Remove prompt-caching-2024-07-31 from all beta arrays in the Skills guide examples:

Before:

betas=["code-execution-2025-08-25", "skills-2025-10-02", "prompt-caching-2024-07-31"],

After:

betas=["code-execution-2025-08-25", "skills-2025-10-02"],

Impact
