List markdown notes in the Obsidian vault, sorted by last modified (newest first). Optionally restrict to a subfolder.

Read a note from the vault. Returns the parsed frontmatter and the markdown body.

Create a new markdown note (parent folders are created automatically). Fails if the note exists unless overwrite is true.

Append text to a note. With 'heading', the text is inserted at the end of that heading's section (the section is created if missing).

Edit a note by exact string replacement. Fails if old_text is not found, or is ambiguous without replace_all.

Update a note's YAML frontmatter by key: merge set values (added or overwritten) and delete remove keys. The note body is left untouched.

Full-text search across the vault (case-insensitive), with optional tag and frontmatter filters. With only a tag/frontmatter filter and no query, lists all matching notes. Pass regex: true to interpret the query as a regular expression.

Move or rename a note, then rewrite [[wikilinks]] and markdown links in every other note so they keep resolving.

Delete a note safely by moving it to the vault's .trash folder (Obsidian's trash convention).

Find notes that link to a given note, via [[wikilinks]] (with #heading/|alias) or ](note.md) markdown links.

Get today's daily note, creating it from a template if needed. Pass 'date' (YYYY-MM-DD) for another day. Notes live in the folder set by OBSIDIAN_DAILY_DIR (default 'Daily').

Get a note's heading outline (level/text/line) and total line count, without reading the full body. Skips '#' characters inside fenced code blocks.

Create a note from a template. Templates live in the folder set by OBSIDIAN_TEMPLATE_DIR (default 'Templates'). Replaces {{date}} (today, YYYY-MM-DD), {{title}} (the new note's filename), and any {{name}} passed in variables; other {{...}} placeholders are left untouched.
