Where YATFA sits — with sources
Agent tools do different jobs, and most teams use more than one. Here is the map, the facts behind it with primary sources, and where others are genuinely stronger.
Three bets on the same problem
All three start from the same conclusion — one AI doing everything fails. They put the fix in different places.

What YATFA adds beyond the table
Capabilities that don’t fit a row. We describe our side only — we don’t claim others lack them.
Directions cut at execution timeEach slice is cut from main after the last one landed.
Visual draftsRendered directions of your real product; the pick is what gets built.
Escalations with historyA stuck change stops and hands over every attempt — instead of looping.
Trust levels per kind of workTests go ahead; features wait; operations always go to a person.
Reviewed investigationsAnswers re-checked before you see them, with an expiry date.
Knowledge that corrects itselfArticles re-read against the code, with corrections on the record.
Dimension by dimension
Every claim about another product links to its primary source. Filter to see where they are stronger — said plainly, so the rest is believable.
