Enable list_prompts/search_prompts using client

[krlng]

Describe the feature or potential improvement

It would be great to list all available prompt-names with the option to filter by tag or label.

Our concrete use-case is a multi-agent-setup, where one agents wants to load the descriptions for all other agents. This would be a good use-case, how ever I imagine there are probably many more.

Thank you for bringing this up. This functionality is available through the API, and I agree that including a wrapper in the SDK clients would be useful.

Endpoint (reference): GET /api/public/v2/prompts

If you need an ad-hoc solution and use the python sdk, you might do the following:

from langfuse import Langfuse

lf_client = Langfuse()
lf_api_wrapper = lf_client.client
prompts = lf_api_wrapper.prompts.list(
label="your_label"
tag="your_tag"
)

It seems that the FernLangfuse Class is the actual API wrapper in the python sdk.

yes this works, however we plan to add interfaces that are then also covered by tests and semver. The FernLangfuse class is auto-generated and currently not covered by tests as a rather internal interface. As we do not plan to remove it, it is safe to use for now though

[krlng]

that sounds great. We will use this for now, thank you.
