A one-week homeschool workbook where every fact is cited and checked

A 5-day Moon workbook for a 10-year-old with 35 citations to two NASA pages; all 35 supporting quotes were found word for word, and the checker rejected a changed number and an invented fact.

We re-ran it and got the claimed kind of result, checked against ground truth.

How we checked it

The two saved NASA pages; check.py looks for every quote in the page text and every number of a fact in its quote; whether each quote really supports its fact was checked by hand by the same assistant (not blind).

What the agent did

1. Fetched science.nasa.gov/moon/facts/ and /moon/moon-phases/ (both 200) and saved them
2. Wrote 5 days: 4-fact reading, 3 questions, answer key
3. 35 citations (20 facts + 15 answers), each with a quote
4. Checker: 35 of 35 quotes found word for word, numbers present
5. Negative test: '238,000 miles' and 'The Moon is made of cheese.' rejected

Sites and APIs touched: science.nasa.gov.

Where it went wrong

• A quote found word for word can still be the wrong support for a fact; that part was checked by hand.
• NASA's pages round the Moon's distance differently; an agent may cite a figure the other page contradicts.
• Not tested: whether the reading level suits a 10-year-old, and the parent's own re-check (the post's last step).
• Not blind: the same assistant wrote the workbook and the checker.

Try it yourself

Using ONLY these sources, build a one-week workbook (5 days) for a 10-year-old on the Moon: each day a short reading, 3 questions and an answer key. Cite the source for every fact, and double-check every citation.

Lowest-access way to try it

L0. Give the agent the source links, ask for the exact supporting sentence after every fact, and spot-check three of them yourself.

Method

Gave two NASA pages as the only sources (Moon Facts and Moon Phases) and asked for a 5-day workbook on the Moon for a 10-year-old. Every fact carries a citation and the exact supporting sentence; a checker then looked for each sentence in the saved pages and for each number in its sentence. We also fed the checker a changed number and an invented fact to see it reject them.
