Create and edit Obsidian Bases (.base files) with views, filters, formulas, and summaries. Use when working with .base files, creating database-like views of notes, or when the user mentions Bases, table views, card views, filters, or formulas in Obsidian.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Obsidian Bases Skill
## Workflow
1. **Create the file**: Create a `.base` file in the vault with valid YAML content
2. **Define scope**: Add `filters` to select which notes appear (by tag, folder, property, or date)
3. **Add formulas** (optional): Define computed properties in the `formulas` section
4. **Configure views**: Add one or more views (`table`, `cards`, `list`, or `map`) with `order` specifying which properties to display
5. **Validate**: Verify the file is valid YAML with no syntax errors. Check that all referenced properties and formulas exist. Common issues: unquoted strings containing special YAML characters, mismatched quotes in formula expressions, referencing `formula.X` without defining `X` in `formulas`
6. **Test in Obsidian**: Open the `.base` file in Obsidian to confirm the view renders correctly. If it shows a YAML error, check quoting rules below
## Schema
Base files use the `.base` extension and contain valid YAML.
```yaml
# Global filters apply to ALL views in the base
filters:
# Can be a single filter string
# OR a recursive filter object with exactly ONE key: and, or, or not
and:
- 'status == "active"'
- not:

The line at the top of this page pins the label git:20260919.d351127, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
