About
Mackforge Harness Toolbox is a plugin bundle for AI coding tools published by Daniel Mack. Marketplaces we read that list it: 1 (Community GitHub marketplaces). We first saw it on 2026-10-16 and have recorded no change since. As of our marketplace pass on 2026-10-17.
A tested harness for durable work across coding agents: CLAUDE.md/CHECKPOINT.md state files, an orientation gate, an interview-before-you-build gate and other hooks, and fourteen skills that encode the conventions so you never re-explain them.

Want this mark on your plugin in our catalog?
Prove you maintain it with a file in its repository, a file on your domain or a DNS record, and you can show this mark on the card, with live banners for your site and README. How verification works
You also get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and its remote endpoint goes on monitoring as a web service.
Data comes from public marketplace files in GitHub repositories of their authors. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
