AI integrations should follow OTel spec and report the gen_ai.operation.name with the values listed in sentry conventions if applies getsentry/sentry-conventions#225, this PR renames gen_ai.operation so that if one of values applies, then that value MUST be used.

because langchain also has a separate create_agent API: https://docs.langchain.com/oss/python/langchain/agents#static-model

so to me it would seem that we should use chat for individual invokations and invoke_agent if the agent is invoked

AI integrations should follow OTel spec and report the gen_ai.operation.name with the values listed in sentry conventions if applies getsentry/sentry-conventions#225, this PR renames gen_ai.operation so that if one of values applies, then that value MUST be used.

m: isn't this for single llm calls? in that case wouldn't chat be more suitable?

because langchain also has a separate create_agent API: https://docs.langchain.com/oss/python/langchain/agents#static-model
so to me it would seem that we should use chat for individual invokations and invoke_agent if the agent is invoked

Makes sense, i kept going back and forth on this one. having a separate create_agent API settles it

l: I think it would be better to use sets in this method and then just do a lookup in the condition e.g. INVOKE_AGENT_OPS that contains the operations we want to map to invoke_agent
