Writing Obsidian's Own File Formats

JSON Canvas is the open infinite-canvas format — nodes, edges and groups on a whiteboard, not the graph view of links between notes. Bases is the database feature built into Obsidian since 1.9, with views, filters and formulas in .base files; it is not the third-party Dataview. The CLI skill covers plugin and theme development. Defuddle strips web pages to clean markdown; the author says the point is saving tokens. OpenCode users: clone the whole repo into the skills directory — copying only the inner folder will not install — then restart.
