Function appendToNote

appendToNote(
    vault: Vault,
    args: {
        content: string;
        path?: string;
        separator?: string;
        title?: string;
    },
): Promise<{ appended_bytes: number; mtime: string; path: string }>
Append content to the end of an existing note, with a configurable separator.

Resolves the target by path or title (same fuzzy-match as wikilinks). The default separator is "\n\n" — a blank line — so appends read as a new paragraph. Pass separator: "" for raw concatenation. WRITE TOOL — only registered when the server is started with --enable-write.
Parameters
- vault: Vault
  The vault. Must allow writes.
- args: { content: string; path?: string; separator?: string; title?: string }
  One of path or title is required. content is the text to append. separator defaults to "\n\n".
Returns Promise<{ appended_bytes: number; mtime: string; path: string }>
{ path, mtime, appended_bytes } — the appended byte count includes the separator.
Throws
If the vault is read-only or the target can't be resolved.

Throws
If path resolves outside the vault.
Example
```
await appendToNote(vault, {
  path: "Journal/2026-05-15.md",
  content: "Afternoon: shipped v3.6.0-rc.3",
  separator: "\n\n## "
});
```
