@KunalSin9h Need your help. Can you try out xbom tool and help add signatures for popular AI SDK for Python only?

Example: When I can xbom against a Python code repository, it should detect usage of popular AI libraries like OpenAI, Anthropic, Google AI, LangChain etc.

No need to be comprehensive.

• Cover the most popular AI SDKs (for Python)
• Validate with real life applications from GitHub
• Document your experience with the goal that eventually we will have a Signature Contributor's guide for the community

We want the community to own xbom signatures.

@KunalSin9h I see this issue is almost done. Only Transformers signature is pending. Can we add it please so that we have this issue completion for xbom?

@KunalSin9h How much effort is required to get this done?

@abhisek I am doing transformer, read docs but got one issue, which is blocking #45.
