Browse every defined term, see where it applies, and follow it across regulations. Definitions are derived artifacts, regenerated from the primary legal-text corpus. Where more than one rulebook defines a term, every regime-scoped variant is kept — the cross-rulebook collision index and article-scoped usage indexes are exposed under [`/api/definitions/`](https://github.com/jakesenfti/micawtf/tree/main/api/definitions/index.json) and [`/api/rulebooks/:law/article-definitions.json`](https://github.com/jakesenfti/micawtf/tree/main/api/rulebooks/mica/article-definitions.json). ## By rulebook 227 definitions across 12 rulebooks.

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://www.mica.wtf/definitions/definitions/readme.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
