      description: Returns all tags found across all files in the vault, drawn from both inline (`#tag`) and frontmatter tag syntax. Each tag is returned without the `#` prefix. Hierarchical tags (e.g. `work/tasks`) also contribute a count to every parent prefix (e.g. `work`), mirroring how Obsidian displays tag counts in its sidebar.
