* Overview
|
|
Structural manipulation tools for Org-mode files. This skill handles reading, writing, and modifying Org files at the AST level: finding headlines by ID or title, setting properties and TODO states, adding new headlines, generating UUIDs, and converting ASTs back to Org text. It also implements the privacy filter — when reading an Org file, it strips headlines tagged with ~@personal~ (or any tag in ~bouncer-privacy-tags~) and rejects files with matching ~#+FILETAGS:~.
