LGTM so far. I assume you will take it out of draft when you want a final review.

Pull request overview
This PR extends Python prompt-injection modeling and tests to cover additional LLM SDK call patterns (OpenAI responses + chat.completions, and Anthropic messages APIs), ensuring the query flags user-controlled data flowing into these prompt construction sinks.
Changes:
- Added new OpenAI prompt-injection sinks for
chat.completions.create(messages[].content)andresponses.create(input/instructions). - Introduced Anthropic prompt-injection sink modeling (system prompts + message content) plus corresponding type modeling.
- Expanded the CWE-1427 PromptInjection query test suite and updated expected results accordingly.

I have a few repos where I'd like the prompt injection to trigger, and I've verified that it at least finds new sources for these:
