This skill enables Claude Code to create and edit valid Obsidian Bases (.base files) including views, filters, formulas, and all related configurations.
Works with
AI-first code editor with Composer
Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionobsidian-basesExecute the skills CLI command in your project's root directory to begin installation:
Fetches obsidian-bases from davila7/claude-code-templates and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate obsidian-bases. Access via /obsidian-bases in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

This skill enables Claude Code to create and edit valid Obsidian Bases (.base files) including views, filters, formulas, and all related configurations.
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.
Base files use the .base extension and contain valid YAML. They can also be embedded in Markdown code blocks.
# 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 formulas
property_name: Average
Filters narrow down results. They can be applied globally or per-view.
# Single filter
filters: 'status == "done"'
# AND - all conditions must be true
filters:
and:
- 'status == "done"'
- 'priority > 3'
# OR - any condition can be true
filters:
or:
- 'file.hasTag("book")'
- 'file.hasTag("article")'
# NOT - exclude matching items
filters:
not:
- 'file.hasTag("archived")'
# Nested filters
filters:
or:
- file.hasTag("tag")
- and:
- file.hasTag("book")
- file.hasLink("Textbook")
- not:
- file.hasTag("book")
- file.inFolder("Required Reading")
