io.github.actualbudget/actual/writing-actual-docs

Use whenever creating, updating, editing, drafting, restructuring, or fixing documentation in the Actual Budget repo — specifically anything under `packages/docs/` (the Docusaurus site published at actualbudget.org/docs) or any change to `.md` / `.mdx` files in that package. Trigger for asks like "add a doc page for X", "update the FAQ", "write a guide for the new feature", "document this setting", "fix the docs about Y", "add a contributing page", or any work on the docs site, even when the user does not explicitly mention style, structure, or conventions. Actual's docs follow strict Docusaurus conventions (front matter, heading levels, image placement and naming, admonition syntax, Title Case, tone of voice, spelling allowlist) and writing them without consulting the project's style guide reliably produces output that fails review and needs to be redone.
