The indexed snippet for this X post says that OpenAI published a complete GPT-5.6 prompting guide and that the author translated the developer docs.

Accordingly, this file does not fill in content that could not be accessed; the verifiable official prompting text for GPT-5.6 can be found in the OpenAI Builder guide and AWS guide in the same directory.
