Obsidian Bases

Use this as a compact workflow and fallback syntax reference. Prefer a separately installed kepano/obsidian-skills obsidian-bases skill, then the current official Bases syntax, for detailed or version-sensitive fields and functions.

Answer design and syntax questions read-only. For a requested .base edit, resolve the user vault and use one inspected transaction; never write the file directly.

Resolve the installed product root from this skill's own location, not from the vault or current working directory:

PRODUCT_ROOT=/absolute/path/to/installed/claude-obsidian
CORE="$PRODUCT_ROOT/scripts/claude-obsidian.py"
test -f "$CORE"

Every ../wiki/references/ link in this file resolves the same way, relative to this skill's own directory under $PRODUCT_ROOT, never relative to the selected vault's wiki/ directory.

Workflow

1. Inspect representative note properties and any existing .base file.
2. Define the smallest filter that selects the intended notes.
3. Add formulas only for values that must be computed.
4. Choose views and display order. Do not assume a view type or option is supported by the user's Obsidian version or installed plugins.
5. Validate YAML, expression quoting, property names, formula references, and null handling.
6. Preview the complete file and expected result set before a mutation.
7. If an edit was requested, read operation-transactions.md, keep the .base file under wiki/, and build one claude-obsidian.transaction.v1 bundle with operation_type: base. Inspect it, then set APPROVAL_SHA256 to the returned approval_sha256 only after review and apply once:
