# Obsidian Bases

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.

## When to Use This Skill

- Creating database-like views of notes in Obsidian
- Building task trackers, reading lists, or project dashboards
- Filtering and organizing notes by properties or tags
- Creating calculated/formula fields
- Setting up table, card, list, or map views
- Working with .base files in an Obsidian vault

## File Format

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

## Complete Schema

```yaml
# 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)'

# Define one or more views
views:
  - type: table | cards | list | map
    name: "View Name"
    limit: 10                    # Optional: limit results
    groupBy:                     # Optional: group results
      property: property_name
      direction: ASC | DESC
    filters:                     # View-specific filters
      and: []
    order:                       # Properties to display in order
      - file.name
      - property_name
      - formula.formula_name
    summaries:                   # Map properties to summary
