For my money it's by far the best Claude Code compliment.
This way of context engineering has definitely been the way to go for me, although I’ve just implemented it myself… using Claude to help generate commands and agents and tweaking them to my liking, lately been using json as well as markdown to share context between steps.
When I'm in the terminal I can call on Agents who can create standardised documents so there is a memory of the product management side of things that extends beyond the context window of Claude.
It guides you through the specification process so that you have extremely tight tasks for Claude to churn through, with any context, documentation and acceptance criteria.
Perhaps there are others similar, but I have found it completely transformative.
An AI tool finding issues in a set of YAML and Markdown files generated by an AI tool, and humans puzzled by all of it.
