How every printable and game is checked

Every page is about its title

Renders the paid and free printables and counts pages that look finished but are not about what their title says — a word search of CAT DOG FISH under any title, a word bank chosen for no topic, Grade 1 addition in a Grade 6 pack. Each kind of defect has a small budget; going over it fails the change.

No generator gives up too often

When a generator cannot find real content for a page's subject it prints something general instead, such as a research organiser. No generator may do that on more than 5% of the pages it makes, and paid pages are counted on their own so they cannot hide behind free ones.

npm run check-fallbacks

The word lists follow the rules

Validates the authored word lists that feed vocabulary, word search, word-bank and fill-in-the-blank pages.

npx tsx scripts/check-topic-terms.ts

Art pages match their titles

Catches art and music pages whose layout does not fit the title — a colouring page that printed a study organiser instead of a picture.

npm run check-art

Packs do not repeat themselves

For every pack sold, it fails when the share of pages that are the same exercise with the items shuffled goes over its ceiling, when a pack ships fewer pages than it advertises, or when a pack reaches its page count by repeating a sheet. It also lists, for a person to review, text that runs outside its box and pages that print their own title where the content belongs.

npm run check-shop

Bundle prices add up

A bundle must cost less than its parts bought separately, its stated saving must never round in our favour, and a bigger group tier must cost less per family than a smaller one.

npm run check-offers

Word problems have sensible answers

Runs the word-problem generator over every title in the catalogue at every grade it appears in, and fails on “NaN”, a negative number of apples, a 0.333… answer, or a line that runs off the box.

npm run check-word-problems

Every algebra question is re-solved

Runs each practice generator over thousands of seeds and solves every question again independently. The answer must be exact, a tap question must contain the right answer exactly once, and the stream must not be a few questions on repeat.

npm run check-algebra

Every Genius Room challenge can be solved

Mazes are walked, coin amounts are proved reachable, and every multiple-choice answer is checked for being the only right one — and no challenge may ask the same question twice.

npm run check-genius

Every game round can be won

Builds every round of every game board and checks it can be finished: the target is reachable and the answer is among the choices. It also fails a board whose eight rounds repeat each other too much, and two games in the same grade and subject that play identically.

npm run check-games

180 different school days

Every take-home day must name a topic that exists, and every one of a grade's days must be genuinely different.

npm run check-takehome

Links to printables resolve

Every printable linked by hand from elsewhere on the site must still exist, so a featured row cannot point at a deleted page.

npm run check-slugs

Page titles and headings are whole

Fails on “undefined” in a title, a doubled brand name, a missing or doubled main heading, a description cut off mid-word, or a page far over its size budget.

npm run check-onpage

Pre-K lessons never ask a child to read

Every preschool and kindergarten writing lesson must have a spoken prompt and must not show its answer as text, because the child cannot read yet.

npm run check-prek-writing
