Start here

The skills run inside the AI tool you already use, on your own work. You don’t need an account on this site.

Two uploads in total: the coach, and the seven Build Cycle skills combined into one file.

  1. Download practice-coach.zip and build-cycle-skills.zip (available with the first release).

  2. In Claude, open Customize → Skills, choose to upload a skill, and pick practice-coach.zip. Don’t unzip it first. Claude expects the zip file itself.

  3. Upload build-cycle-skills.zip the same way.

  4. Check that code execution is turned on in Claude’s settings. Skills need it. On a Team or Enterprise plan, an admin may need to turn it on for you.

  5. Start a new chat and say what you’re working on. Try: “I want to stop rewriting the same weekly update every Friday. Coach me.”

Whether the Free plan supports uploaded skills is still being tested. Paid plans (Pro, Max, Team, Enterprise) do.

  • Your computer unzips the download automatically. Some browsers and Macs do this. Upload the .zip file, not the folder. If you only have a folder, compress it again with the folder itself at the top level.
  • “Skills need code execution.” Turn on code execution in Claude’s settings, or ask your admin.
  • The skill doesn’t kick in. Name it: “use prove-it on this”, or say “coach me”. Each skill also responds to everyday phrasing such as “is this right?” or “I’m stuck”.
  • Too many questions? Say “just do it”. The skill does the task, notes what it skipped, and stops offering for the rest of the session.

A blueprint is a short card for one small build: the smallest useful version, how to check it, and how to break it on purpose to see where it fails.

After that, the skills page lists what each skill does and how to call it, and the concept cards explain the AI ideas the skills use.
