Show HN: A prompt-to-PRD generator that understands your codebase

Hey HN,

I’ve been experimenting with coding agents for a while, mostly using o3 to plan tasks and Claude Code to execute them. That combo worked surprisingly well, but I realized most people don't have a great setup to make that kind of workflow usable.

So I built a small tool that generates PRDs and feature specs from prompts, grounded in your codebase. It uses an agent (similar to Claude Code) to read your repo and write the docs. That's powered by a separate open-source agent SDK I built.

It’s still early and a bit rough to self-host (you’ll need a DB and LLM proxy), but the repo is open-source if you want to explore or build on it.

Would love feedback on what’s useful or what’s missing, or ideas for evolving this into a broader prototyping or background agent coordination tool.
