Rules for creating and editing changeset files in .changeset/ — which @doenet/* packages to list, packages that must never appear, one-directional propagation, the private-flag trap, and changeset file format. Use whenever adding or editing a .changeset/*.md file.
Get the DoenetML source behind a beta.doenet.org / doenet.org activityViewer link. The pages are a client-rendered SPA, so fetching the URL (WebFetch/curl) returns an empty shell — call the content JSON API instead. Use when asked to read, extract, or reference the DoenetML of a Doenet activity link.
Author DoenetML documentation under packages/docs-nextra/ within the Diátaxis framework (Tutorials, Guides/how-to, Reference, Concepts/explanation) — which section a page belongs in, the concept↔guide split pattern, MDX structure, example fences, the AttrPropDisplay machinery, prose vs example math, and the schema/index files that reference pages must keep in sync.
Write and revise DoenetML activities using docs-nextra patterns, with explicit guardrails for how DoenetML differs from PreTeXt.
Write and revise PreTeXt documents using the official guide, with explicit guardrails for how PreTeXt differs from DoenetML.
