What are Obsidian Bases?

Obsidian Bases are YAML-based files that define dynamic, database-like views of notes in an Obsidian vault, allowing for tables, cards, and list views based on file metadata and frontmatter.

Do I need a specific plugin to use these files?

Yes, while this skill helps you write the code, you need the 'Bases' plugin installed in your Obsidian vault to render and interact with the resulting .base files.

Can this skill create complex filters?

Yes, the skill supports nested logical operators (and, or, not) to filter notes by specific tags, folder locations, internal links, or custom frontmatter properties.

Does it support mathematical calculations?

Absolutely. The skill can implement formulas for arithmetic, conditional logic, date formatting, and string manipulation, as well as summary functions like Average, Sum, and Standard Deviation.

What file types does this skill work with?

It primarily manages files with the .base extension but can also help configure Obsidian Markdown files where these database views might be embedded in code blocks.

Productivity & Workflow

Architects and manages dynamic database-like views in Obsidian using .base file configurations.

About

This skill enables Claude Code to master the Obsidian Bases ecosystem, allowing for the creation and editing of .base files that transform static notes into interactive databases. It provides comprehensive support for defining multi-modal views—including tables, cards, lists, and maps—alongside complex logical filtering and custom formula properties. Whether organizing a research vault or building a project management dashboard, this skill ensures that your Obsidian metadata is structured, filtered, and summarized with precision using valid YAML syntax and advanced expression logic.

Key Features

Construct complex, nested filters using and/or/not logical operators.
Define custom formulas for computed properties using date, string, and numeric functions.
Implement automated data summaries like Average, Sum, Median, and Range.
37 GitHub stars
Configure global and view-specific properties and display settings.
Generate valid .base YAML files with support for all view types (Table, Cards, List, Map).

Use Cases

Developing a financial or time-tracking system using custom formulas to calculate totals and averages.
Building a centralized project dashboard that aggregates and filters tasks from across an entire vault.
Creating a visual media gallery using the Cards view to display book covers and metadata.
