This extension is already earning its keep. PromptDC helps me tighten up prompts fast, which translates into better code with fewer reruns. I emailed the developer some feedback and he was super responsive. And the next updates clearly reflected what I mentioned. Feels like a tool that’s actively improving instead of abandoned.
