obsidian-bases makes your assistant create and edit .base files, which are YAML files that show your notes as a table, cards, a list or a map. It follows a six-step workflow: create the file, define scope with filters, add formulas, configure views, validate the YAML and references, then open the file in Obsidian to confirm it renders.

It covers filter syntax with and, or and not, note, file and formula properties, formula functions, the Duration type, default summary formulas and embedding a base in a note. It includes three full examples: a task tracker, a reading list and a daily notes index. A troubleshooting section covers YAML quoting. It bundles a functions reference and no scripts.

Good for

Obsidian users building database-like views of their notes
People who want task trackers or reading lists as a base
Anyone debugging YAML or formula errors in a .base file

Questions

What does the obsidian-bases skill do?

It writes and edits Obsidian Bases files. Those are .base YAML files that give you database-like views of your notes.

How do I install the obsidian-bases skill?

Use the install box at the top of this page.

Does it need the Obsidian CLI?

The SKILL.md does not mention the CLI. It creates the .base file in your vault and ends by asking you to open it in Obsidian to check that the view renders.

What does it get wrong most often?

The skill names common issues itself: unquoted strings with special YAML characters, mismatched quotes in formulas, and referencing a formula that is not defined. It also warns that Duration values do not support division then round.

How is it different from obsidian-markdown?

The kepano/obsidian-skills README lists obsidian-markdown for .md files with wikilinks and callouts, and obsidian-bases for .base files. See the obsidian-markdown page.

Is the obsidian-bases skill safe to install?

It bundles one reference file and no scripts, and names no API key. It creates or edits .base files in your vault, so keep a backup of your vault.
