How we write and check our guides

What you will find

Each guide answers a specific task with an example, a worksheet, a prompt, or code you can inspect. All guides are readable without an account and downloadable as text. The free library is useful on its own; a purchase is not required to complete the examples.

How the work is made

This first edition was drafted and edited with AI assistance. The examples, prompts, and code are original editorial materials. Fictional examples are labeled. They are not customer results or recorded model outputs. We do not imply a human expert reviewed a guide when that review has not happened.

Sources and limits

Technical explanations use primary documentation. U.S. mortgage-document guides refer to the Consumer Financial Protection Bureau and keep calculations tied to explicit fictional assumptions. Those guides organize documents and questions; they do not assess affordability, recommend a loan, or interpret legal compliance.

References support the documented behavior and definitions discussed. Our worksheets and editing methods are original practical suggestions, not claims that the reference organizations endorse SkillStall. Prices, product capabilities, and rules can change; check the current original source before relying on a changeable fact.

What we check

We check article identity, source links, internal links, downloadable text, arithmetic examples, metadata, and the site’s rendered behavior. Storefront and code tests do not establish that a skill activates natively in every AI app or that every model output will be accurate.

Artwork

The illustrations are original generated editorial collages. They are decorative metaphors, not photographs of people, properties, customer outcomes, or evidence. Diagrams and calculators label their assumptions and keep the underlying information visible as text.

Updates and corrections

Dates reflect this edition’s publication or substantive revision. We do not refresh dates just to make unchanged guides look new. If you find an error, keep the guide URL and the sentence or calculation involved. A public correction contact will be added when the project’s email is configured.
