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.

# Obsidian Bases Skill
## Mindset
Obsidian Bases is a YAML-driven query layer over vault notes. Think of `.base` files as live database views, not static tables — they compute and filter in real time against note frontmatter. The key discipline: define your data model in note properties first, then build views on top of it.
**When to apply:** Creating dynamic views of vault notes by tag, folder, or property; building task trackers, reading lists, or dashboards; or when the user asks for table, cards, or list views in Obsidian.
**When NOT to apply:** One-off note organisation, static Markdown tables, or displaying content that does not come from frontmatter properties.
Consider starting with a simple filter and single table view, then optionally adding formulas and multiple views once the data model is validated.
## 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

The line at the top of this page pins the label git:20260316.13efaab, 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.
