The post asks about the default response synthesizer for the propertygraph stuff, tagging two community members. The comments suggest that the response synthesizer is the same as all the indexes, and it is the compact response synthesizer. One community member asks if the actual code or prompts are needed, while another wants to create a unique prompt and inquires about documentation for that. Another community member mentions having the graph response as the context string. A link to documentation on getting and setting custom prompts is provided, which may be helpful.
