Vendored from upstream, pinned at SHA 7765fae. One file lives next to this note:

  • galaxy.xsd — the structured source. Agents and casting should consume this when authoring or validating Galaxy tool wrapper XML, tool tests, output assertions, macros, inputs, outputs, help, citations, and configfile blocks. Sync is manual.

When to consult: authoring or validating tool.xml wrappers, translating tool parameters into Galaxy XML, defining outputs or discovered datasets, writing wrapper tests, or choosing valid Galaxy assertion elements and attributes. Do not use this for author-galaxy-tool-wrapper, which emits UDT YAML.
