Key Points

The author built a “self-healing” PRD system for Claude Code that gathers all necessary PRD information and can review existing code to answer those requirements questions.
The system decomposes the PRD into separate files and progresses to subsequent steps only after earlier parts are completed.
At the end of each part, it reaches out to Codex and performs an independent code review to catch issues.
When applied to an existing project, the feedback loop with Codex helped surface additional problems and automatically opened new PRDs to address them.
Overall, the workflow continuously iterates by scanning for issues while extending the codebase, enabling more reliable planning and implementation cycles.

I went out to create something that would would build prds for me for projects I'm working on.

The core idea it is that it asks for all of the information that's needed for a PRD and it could also review the existing code to answer these questions. Then it breaks up the parts of the plan into separate files and only starts the next part after the first part is complete.

Added to that is that it's reaching out to codex every end of part and does an independent review of the code.

What I found that was really cool is that when I did that with my existing project to enhance it, the system continued to find more issues through the feedback loop with codex and opened new prds for those issues.

So essentially it's running through my code finding issues as it's working on extending it
