My friend Anton put me onto grill-me, and it’s turned out to be genuinely handy — I’ve used it a handful of times now to turn a loose idea into something I can actually commit to. It needs no repo and creates no files, just a structured interview that keeps going in rounds until the vague parts get pinned down.
grill-with-docs is the one I reach for most, though. Same interview format, but it writes what you agree on straight into the repo: a CONTEXT.md glossary as terms resolve, and an ADR under docs/adr/ for anything hard to reverse or worth explaining later. I was already writing ADRs by hand, so this slotted straight into that habit, and now it keeps the format consistent across every repo I touch at work.
I haven’t tried wayfinder yet, but it looks like the natural next step for anything too big for a single grilling session. Instead of a conversation, it charts a multi-session effort as a map of decision tickets on the issue tracker, so nothing gets built until the open questions are actually resolved.
