Recreated prompt

The source didn't share its exact prompt, so we wrote one from what it describes. The result shown is the source's, not ours.

What the prompt labels mean

The person didn't share their exact words, so we wrote this from what they described. We haven't tested it, and they didn't use this exact version.

Using the course brief below (visual style, module structure, tone and content rules), make this week's interactive lesson for my 10-year-old on [TOPIC, E.G. BIKE SAFETY]. Include a welcome screen, the basics, a step-by-step skills walkthrough, a safety checklist, a 'what to do if something goes wrong' module, a short quiz and a certificate, all in one self-contained HTML file.

This prompt has blanks to fill in, like [PASTE COURSE BRIEF]. We'll copy it instead of filling it in, so you can edit it before you send.

The source used Claude and Claude Cowork, which can take actions in a browser or app. These are general chat tools, so results may differ, and a normal chat may only give you a plan.

Optional stronger version

Our rewrite with extra checks. The poster didn't test it.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: A short, engaging safety lesson for my child that I can reuse as a weekly format.

Questions to ask me first:
- How old is your child, and what topic is this week?
- What does your child already know about it?
- Do you have a saved course brief, or should we write one first?

Inputs (fill in or confirm):
- Child's age: [AGE]
- Topic: [E.G. FIRE SAFETY]
- What they already know: [NOTES]
- Course brief: [STYLE, MODULES, TONE]

Rules:
- Keep the language right for the child's age.
- Make the 'what to do if something goes wrong' module the most careful part.
- Use one self-contained HTML file with no live API calls.
- Note anything a parent should demonstrate in person.

Checkpoint: Show the module outline before building the full lesson.

If you get stuck: If a safety step is uncertain, point to a trusted source rather than guessing.

Verify before you finish: The quiz answers match the lesson content, and the file opens offline.

Output: One HTML lesson file plus a short note for the parent.

Done when: My child can work through this week's lesson on their own.

Outcome

Matthew M wanted to teach Matthew's 10-year-old son practical safety and life skills, starting with swimming confidently and what to do if something goes wrong in the water, but writing a polished lesson from scratch every week wasn't sustainable. With Claude, Matthew first built one interactive HTML swim-safety course with its own colors, fonts and a progress tracker styled like pool lanes, split into a welcome screen, basics, a skills walkthrough, a safety checklist, an emergency module, a quiz and a certificate. A version that called the Claude API live from inside the page only worked while open in Claude.ai and sometimes failed to generate a section cleanly, so they switched approach: Claude wrote the course format up as a reusable brief. Each week Matthew pastes the brief and a new topic, such as bike or fire safety, into Claude Cowork and gets back a finished, self-contained HTML lesson to hand over, with no app to maintain.
