Dev Skills is a pack of twelve skills for AI agents that runs the whole product loop: figure out what to build, prove someone wants it, design it, build it, break it on purpose, ship it, answer the support, find the bug, and write down the lesson. Your agent runs the loop; you make the calls. $97 one-time, lifetime access, built by Brad Hart of Make More Marbles from one real product over five months and roughly a hundred and ninety rounds of work.
$97 one-time for the first hundred buyers, then $147. Lifetime access at whatever you paid, and every update free. No subscription: it runs on the AI agent you already have. Thirty-day guarantee. All four skill packs together are $197.
Because the developer isn't the bottleneck. The bottleneck is everything around the developer: deciding what to build, knowing whether anyone wants it, catching what's broken before a customer does, and answering the support afterwards.
Then give it to them. It's nine stages of how a real product gets built and kept alive, written down. Most teams have three of them and improvise the rest.
Yes, and that's the problem. Code is the cheap part now. What's expensive is building the wrong thing beautifully, shipping it without testing it, and finding out from a customer.
One real product, built over five months, roughly a hundred and ninety rounds of work, with every incident and every test written down as it happened.
We built and tested it on Claude Code, and that's the path we support. The skills are plain English files, so any capable agent can read them.
It tells us. Your agent sends a report at the end of a session, that becomes a fix, and the fix ships to you as an update.
No. Your code stays on your machine; nothing in the pack uploads it. The only thing that leaves is the end-of-session gap report your agent sends us: which pack version you ran, your agent's name and version, your OS and machine, your Claude Code version, what you tried and what broke or was missing, the steps and errors, and an optional diff of the fix it would make. Not your code. Your outputs are yours; see the license.
