Sourced answers to everyday "why is my…" questions — health, pets, home, plumbing, tech, cars.
Scored across 5 tools
Each tool has a distinct role: search_articles finds articles, get_article retrieves one by slug, list_topics enumerates categories, and list_calculators/list_quizzes cover separate interactive content types. Descriptions explicitly link get_article to search_articles output, reducing confusion.
All names follow a consistent verb_noun snake_case pattern (get_article, list_calculators, list_quizzes, list_topics, search_articles). The convention is predictable across the entire set.
Five tools are well-scoped for a read-only content-discovery server: one search, one retrieval, one taxonomy lister, and two parallel interactive-content listers. No tool feels extraneous or missing at this size.
The surface covers all apparent content types—articles, calculators, quizzes, and topics—with search, retrieval, and browsing support. Because calculators and quizzes are intentionally client-side, no additional get/details tools are needed.
Get the direct answer, the causes the article covers, and its FAQ for one article, by slug (from search_articles). Returns a summary, not the full text — the article URL has the complete step-by-step fix and the sources.
Inputs: slug, query.
Find WhyIsMy.org's free interactive calculators, checkers and estimators (dosage, health, eldercare cost, pet, home and car tools). Both arguments are optional: omit everything to browse, pass query and/or category to narrow. Each result is a one-line teaser plus a link — the calculators are interactive and compute a personalized result client-side in the user's browser, so send the user to the URL for their result instead of estimating it yourself.
Inputs: limit, query, category.
Find WhyIsMy.org's free ten-question quizzes (health, tech, cars, home and eldercare topics) with instant explanations and a certificate of completion. Both arguments are optional: omit everything to browse, pass query and/or category to narrow. Each result is a one-line teaser plus a link — a quiz is interactive and scores the user in their own browser, so send the user to the URL to take it instead of answering the questions yourself.
Inputs: limit, query, category.
List the subject areas covered on WhyIsMy.org with an article count for each. Takes no arguments. Use the returned slugs as the topic argument to search_articles.
Inputs: no named parameters.
Find WhyIsMy.org articles answering a "why is my…" question. Returns titles, summaries and URLs. Both arguments are optional: omit query to browse, pass topic to bias results toward one subject area. The returned summaries are partial — send the user to the article URL for the full diagnosis, fixes and cited sources.
Inputs: limit, query, topic.
