Obsidian Dev Rules

Obsidian is extended two ways: plugins (TypeScript against the Obsidian API) and themes/snippets (CSS). This skill mirrors the official developer docs at https://docs.obsidian.md so you can build and review Obsidian plugins/themes without re-fetching. The API ships as the obsidian npm package; the canonical starting point is the obsidian-sample-plugin.

When to use this skill

• Building, debugging, or reviewing an Obsidian plugin (lifecycle, commands, settings, UI, views).
• Reading/writing notes via the Vault API; manipulating the active note via the Editor API.
• Subscribing to events, registering Markdown post-processors / code-block processors, or CodeMirror 6 editor extensions.
• Building a theme (CSS variables, theme.css, manifest) or snippets.
• Releasing/submitting a plugin or theme to the community directory.
