What problem does it solve? Xojo is obscure enough that most code examples online use the removed API 1.0 rather than current API 2.0, so AI agents recalling Xojo facts from memory produce deprecated or wrong code. This skill gives the agent a local, grep-able copy of the official Xojo documentation so every class, property, method, and event is looked up instead of recalled. ## Core Features & Use Cases - Local documentation mirror: Downloads the official documentation archive and converts it into Markdown, with classes.tsv and members.tsv indexes covering over two thousand pages and fifteen thousand members. - Deprecation lookup: Each index row records deprecation flags, the release that deprecated the symbol, its replacement, and hazard notes about changed index bases, epochs, and error models. - Project file format references: Documents the .xojo_project, .xojo_code, .xojo_window and other text project formats, plus blank starter projects for Desktop, Console, Web, iOS, and Android. - Deprecated API checker: scripts/check-deprecated.py scans Xojo source files and reports API 1.0 symbols with their replacements, usable as a command-line tool or a Claude Code hook. - Use Case: While writing Xojo code, the agent greps members.tsv to confirm DesktopListBox.RowCount exists and is current, reads the class page for its exact signature, and avoids the deprecated ListBox.ListCount form. ## Quick Start Ask the agent to look up a Xojo class or method in the local documentation before writing or reviewing any Xojo code.
