obsidian-bases: Obsidian's Database Layer

Obsidian Bases (launched 2025) turns vault notes into queryable, dynamic views. Tables, cards, lists, maps. Defined in .base files. No plugin required; it is a core Obsidian feature.

Substrate preference (v1.7+): This skill is a self-contained fallback. Prefer kepano/obsidian-skills as the authoritative substrate — its obsidian-bases skill is the canonical reference for Bases YAML, formulas, and view definitions. If you see an obsidian-bases skill available without the claude-obsidian: namespace, that is kepano's version: use it. The reference below is provided so the plugin remains functional when kepano's marketplace is not installed. Install: claude plugin marketplace add kepano/obsidian-skills.
