references/in this document is written relative to this document (for examplereferences/...) — the form GitHub resolves when someone opens the file in a browser. Theread_filetool resolves the same string against the skill that owns it, so the agent and a human reader reach one file. When adding new skill docs, always use the relative form, and keep reference paths unique across skills: a path two skills both carry is reported as ambiguous rather than guessed.
