Hey, one of the creators here. As mentioned in the post, TestGen-LLM (by Meta) focused on Kotlin, and the prompts were very Kotlin-oriented. In Cover-Agent (by CodiumAI) we tried to reimplement Meta's work, and stay mostly similar to the original implementation, although we did a bit improved the prompts. But it isn't generic enough. We believe we know how to improve generality, as we did with our PR-Agent, and here is a rough plan: https://github.com/Codium-ai/cover-agent/issues/13
