 Layout references in `create_layout.parent_layout_id`, `add_layout_placeholder.layout_id`, `add_slide`, `insert_slide`, `set_slide_layout`, and `list_layout_placeholders` accept either a layout id or a layout name. Name matching prefers exact id, then exact name, then case-insensitive name.
 
+Use `list_masters` when you only want layouts with `kind: "master"` instead of the full mixed layout list.
+
 `insert_slide` accepts `index` or `after_slide_index`. If neither is provided, the new slide is inserted immediately after the active slide, or appended if no active slide is set yet.

 Comment threads are supported through `set_comment_author`, `add_comment_thread`, `add_comment_reply`, `toggle_comment_reaction`, `resolve_comment_thread`, and `reopen_comment_thread`. Thread anchors resolve as `th/<thread_id>`, and comment records appear in both `inspect` and `to_proto`.
 
+Use `list_comment_threads` for an explicit collection payload and `get_comment_thread` when you already know the thread id.

+Example list comment threads:

+
+Example get comment thread:
+`{"artifact_id":"presentation_x","actions":[{"action":"get_comment_thread","args":{"thread_id":"thread_1"}}]}`
+
 Charts support richer series metadata plus `update_chart` and `add_chart_series`, including legend, axis, data-label, marker, fill, and per-point override state.
 
 Exported PPTX files embed Codex metadata so rich text, comment threads, and advanced table/chart state round-trip through `export_pptx` and `import_pptx` even when the base OOXML representation is lossy.
