Obsidian Bases

If you're using Obsidian Bases to create database-like views of your notes, this skill lets Claude generate and edit .base files with proper YAML structure. It handles the full schema: table/card/list views, nested filters with and/or/not logic, formulas for computed properties, grouping, and custom summaries. The filter syntax alone is worth having this around, since getting the recursive structure right by hand gets tedious fast. Also covers all the file properties, date arithmetic, and string functions you can use in formulas. Basically turns Claude into someone who actually knows the Bases schema instead of guessing at YAML that might work.

Obsidian Bases Skill

This skill enables Claude Code 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)'
