From your idea to a first PRD

Prepare your project and helper

Open the project directory in Claude Code. Use a separate project for edition 4.0 and keep your work from 3.0.

You need Node.js 20+; 10xDevs 4.0 requires 10x-cli 1.22.2 or newer. Run commands through npx @latest — an old global 10x will skip 10x-idea-check. Check the version:

npx @przeprogramowani/10x-cli@latest --version

In the project directory, add both complete helpers — setup and guide, including their references. No login is needed. --tool is required:

npx @przeprogramowani/10x-cli@latest helpers install --tool claude-code

Ask the agent to read .claude/skills/10x-cli-setup/SKILL.md and help prepare the environment. Helpers from 1.22.1+ take lesson setup through all four skills, including 10x-idea-check. Keep an already working installation. If the CLI reports a conflict, preserve your files and inspect it with the helper.

npx @przeprogramowani/10x-cli@latest helpers install --tool copilot

test -s .github/skills/10x-idea-check/SKILL.md

Ready when: The helpers are in your project and the agent can read them.

Get the lesson’s skills

If your CLI session is valid and you have course access, skip login. Otherwise, sign in with a magic link to your course account email:

npx @przeprogramowani/10x-cli@latest auth --method email

Enter your course account email. Open the magic link in your inbox; the terminal waits for confirmation.

npx @przeprogramowani/10x-cli@latest auth --method circle

Fetch the whole m1l1 lesson from 10xDevs 4.0 — not just init/shape/prd. A full get also writes 10x-idea-check. Dry-run first (it writes nothing), then get without that flag:

npx @przeprogramowani/10x-cli@latest get m1l1 --course 10xdevs4 --tool claude-code --lang en --dry-run

npx @przeprogramowani/10x-cli@latest get m1l1 --course 10xdevs4 --tool claude-code --lang en

Confirm the skill is in the project directory. A missing file means an old helper, a three-skill get, or a CLI below 1.22.1 on a filtered setup:

test -s .claude/skills/10x-idea-check/SKILL.md

If the test fails, add 10x-idea-check on its own via npx @latest (1.22.2 or newer for 10xdevs-4). --dry-run still writes nothing — after the preview, run it without that flag:

npx @przeprogramowani/10x-cli@latest get m1l1 --type skills --name 10x-idea-check --course 10xdevs4 --tool claude-code --lang en --dry-run

npx @przeprogramowani/10x-cli@latest get m1l1 --type skills --name 10x-idea-check --course 10xdevs4 --tool claude-code --lang en

Or ask the agent to read .claude/skills/10x-cli-guide/SKILL.md. Give it this goal — the list must include 10x-idea-check:

Help me download the complete 10x-idea-check, 10x-init, 10x-shape and 10x-prd skills for lesson m1l1 in 10xDevs 4.0, in English, for Claude Code. Show the proposed changes first. Do not skip 10x-idea-check.

Check the references with guide as well: 10x-idea-check (examples, assessment-guide, 4.0 dates) and the PRD schema in the 10x-shape directory, plus the separate lesson rules. One SKILL.md file is not the complete set.

Ready when: You have 10x-idea-check, init, shape and prd with their supporting files.

Work through your idea

In the lesson, 10xCards addresses the time it takes to create flashcards. Use that example or an idea of your own. First ask the agent to use the downloaded 10x-init: it prepares context while preserving existing files.

Next, use 10x-shape with the agent. Answer its questions about the user, problem and scope, then read the recorded decisions before continuing.

Ready when: Your notes describe the user, problem and agreed MVP scope.

Write the PRD and check the result

Ask the agent to use 10x-prd with your shape notes. Open both documents: do they describe the same user and problem? Does the PRD preserve the agreed scope and what you are leaving out for now?

Ready when: You have two consistent documents for the next part of the course.

The lesson requires an account with access to 10xDevs 4.0. This page does not grant access.
