Search the vault's markdown files.

Read a note by wiki-link name (e.g. 'icegate') or vault-relative path (e.g. 'notes/icegate.md'). Returns the resolved path and full content.

Graph neighborhood of a note: resolved outgoing [[wiki-links]], unresolved link targets, backlinks (notes linking here), and up to 10 notes sharing frontmatter tags.

Run read-only SQL (DuckDB dialect; SELECT/WITH only) over the vault metadata index. The index is rebuilt from the files — it is never a source of truth.

Schema: notes(path, name, title, type, tags VARCHAR[], aliases VARCHAR[], date, status, frontmatter JSON, modified TIMESTAMP, size, body /* full note text — SELECT specific columns, not * /) links(source / path /, target / wiki-link name as written */)

Examples: SELECT type, count() FROM notes GROUP BY type ORDER BY 2 DESC SELECT path, title FROM notes WHERE list_contains(tags, 'memory') SELECT target, count() n FROM links GROUP BY target ORDER BY n DESC LIMIT 20 SELECT path, json_extract_string(frontmatter, '$.status') FROM notes WHERE type = 'projects'

Most recently modified notes, optionally filtered by type.

Create an atomic idea note in notes/ (one idea per note, template frontmatter enforced). Use for durable ideas/insights worth keeping — search first to avoid duplicating an existing note; link related notes in the content with [[wiki-links]]. Fails if the note already exists.

Surgically correct an existing note by exact string replacement.

old_text must occur exactly once in the note's current text — read_note first and copy the passage verbatim, adding surrounding lines if it is not unique. Works anywhere in the file, frontmatter included. Prefer this over update_note for corrections: it cannot drop text you did not quote.

Rename a note to a new title. The file becomes slugify(new_title).md in the same directory, the first H1 heading is set to the new title, and [[wiki-links]] to the old name anywhere in the vault are rewritten to the new one (|alias and #heading forms preserved). Fails if a note with the target name already exists. Returns old_path, path, links_rewritten.

Rewrite a note's entire body. The frontmatter block is preserved verbatim (use edit_note to change frontmatter). Everything below it is replaced with content — read_note first and carry forward anything that should survive. For targeted corrections use edit_note instead.

Add an open action item to the vault inbox (the source of truth for all open action items). Use for tasks/follow-ups, not ideas or status.

Append a timestamped entry to today's journal Log — for decisions, conclusions, work accomplished, and key insights as they happen.

Force a rebuild of the metadata index from the files on disk. Returns note and link counts.
