The guidance for this skill ships with the Diffusion Studio app, so it always matches the installed version. Read it from there and trust it over memory; it belongs to the app, so never edit it.
The docs live inside the app bundle at Diffusion Studio.app/Contents/Resources/docs (usually under /Applications). Start with skills/editor.md and follow it for the rest of the session. It links to the tool and JSX reference, guides, runnable examples, and the brand kit in the same folder.
The app exposes its tools through an MCP server (media_probe, capture, check, …). The dapi CLI provides the same tools from a shell: dapi media grab corresponds to media_grab.
If neither the Diffusion Studio tools nor dapi is available, or the app is not installed, read installation.md.
