Obsidian Bases

If you're building databases in Obsidian using the Bases plugin, this skill lets Claude create and edit those .base YAML files directly. It handles the full spec: table/card/list views, nested filters with and/or/not logic, formulas that compute values from properties, grouping, and custom summaries. The syntax is pretty involved,filters can nest recursively, formulas support date arithmetic and conditionals, and there's a whole function library for string manipulation and date formatting. Most useful when you're generating complex views programmatically or need Claude to update filters and formulas without you writing YAML by hand. The skill includes the complete schema and function reference, so Claude knows what's valid.

Obsidian Bases Skill

This skill enables skills-compatible agents to create and edit valid Obsidian Bases (.base files) including views, filters, formulas, and all related configurations.

Overview

Obsidian Bases are YAML-based files that define dynamic views of notes in an Obsidian vault. A Base file can contain multiple views, global filters, formulas, property configurations, and custom summaries.

File Format

Base files use the .base extension and contain valid YAML. They can also be embedded in Markdown code blocks.

Complete Schema

# Global filters apply to ALL views in the base
filters:
  # Can be a single filter string
  # OR a recursive filter object with and/or/not
  and: []
  or: []
  not: []

# Define formula properties that can be used across all views
formulas:
  formula_name: 'expression'

# Configure display names and settings for properties
properties:
  property_name:
    displayName: "Display Name"
  formula.formula_name:
    displayName: "Formula Display Name"
  file.ext:
    displayName: "Extension"

# Define custom summary formulas
summaries:
  custom_summary_name: 'values.mean().round(3)'
