## What it does

The skill teaches Claude to handle `.base` files — YAML documents that describe dynamic views over notes in an Obsidian vault. One file can hold several views, shared filters, formulas, property settings and custom summaries. Claude builds the whole file, not fragments of it.

The schema is spelled out: global filters built from `and`, `or` and `not`, the `formulas`, `properties` and `summaries` sections, and a list of views typed `table`, `cards`, `list` or `map`. Each view takes `limit`, `groupBy`, its own filters, an `order` list of properties and summaries. There is also a reference for comparison operators, note, file and formula properties, the `this` keyword, and functions from `if()` and `date()` to `icon()` and `escapeHTML()`.

Formulas derive values from properties: arithmetic, conditionals, string and date formatting. Dates add and subtract with units such as `1M`, `7d` or `2h`. The skill only produces YAML — if Bases are not enabled in your vault, Obsidian is what renders the result, so check that first.
