# Edit just one part of a note

Until now, fixing one bullet meant resending the whole note. Three new modes on `notes-update` change that.

`insert_after` and `insert_before` slip new text in right after or before a snippet you point at. Useful for adding a line under a heading without touching the rest.

`replace_find` swaps a unique snippet for new text. Pass an empty `replace_with` and the snippet gets deleted cleanly.

Every anchor has to match exactly once. If it appears twice, or not at all, the call errors and the note stays untouched. No silent edits to the wrong place.

**Why this matters:** most edits are small. A typo. A stale link. A new bullet under a section. Now your AI can make that edit with one short call instead of resending two thousand words.
