Obsidian Bases

What it does

This skill enables an AI agent, specifically Claude Code, to create and edit Obsidian Bases (.base files). Obsidian Bases are YAML-based configuration files that define dynamic views of notes within an Obsidian vault, allowing for structured organization and filtering of information. The skill supports creating views, filters, formulas, property configurations, and custom summaries within these Base files.

When to use it

• Creating database-like views of your notes in Obsidian.
• Building task trackers, reading lists, or project dashboards using note properties.
• Filtering and organizing notes based on specific tags or properties.
• Generating calculated fields (formulas) within your note organization system.

Key capabilities

• Creation and editing of valid .base files.
• Defining global filters that apply to all views in a Base file.
• Creating formulas for use across multiple views.
• Configuring display names and settings for properties.
• Defining custom summary formulas.
• Generating various view types: table, cards, list, or map.

Example prompts

• "Create an Obsidian Base to track my reading list, with columns for title, author, status (read/unread), and date started."
• "Generate a Base file that filters notes tagged 'project' and displays them in a card view sorted by due date."
• "Write a formula property called wordCount that calculates the number of words in each note."

Tips & gotchas

• Obsidian Bases are written in YAML, so proper formatting is crucial for validity.
• The skill works best with Claude Code as it’s specifically designed to handle .base file syntax and structure.
