Nine hooks. Position values (offset, cursor, from, to) are UTF-16 code-unit offsets into the markdown source as persisted on disk.

docs.selectDoc

Open the given file path in the docs editor for this applet and focus it. Fails if the docs editor is not mounted.

Params: { resource_id: string; pane_id?: string; path: string } - path is relative to the applet folder. Returns: { opened_path: string } Permission: docs:read Handler: Frontend

docs.createDoc

Create a new markdown doc at the given path with optional initial content. Fails if the path already exists (no silent overwrite). Emits an activity log.

Params: { resource_id: string; path: string; content?: string | null } Returns: { path: string } Permission: docs:write Handler: Rust

docs.getOpenedFile

Return the file currently open in the docs editor: path, current buffer content, dirty state, and cursor position.

Params: { resource_id: string; pane_id?: string } Returns: { path: string | null; content: string; is_dirty: boolean; cursor: number } - path: null if no file is open. Permission: docs:read Handler: Frontend

docs.moveCursor

Move the cursor in the opened file to the given character offset.

Params: { resource_id: string; pane_id?: string; offset: number } Returns: { cursor: number } (clamped if out of bounds) Permission: docs:write - cursor moves are visible interactive state changes. Handler: Frontend

docs.searchOpened

Search the currently opened file’s buffer for a query. Returns match ranges as character offsets.

Params: { resource_id: string; pane_id?: string; query: string; regex?: boolean; case_sensitive?: boolean } Returns: { matches: Array<{ from: number; to: number }> } Permission: docs:read Handler: Frontend

docs.search

Grep across markdown files in the docs applet’s folder.

Params: { resource_id: string; query: string; regex?: boolean; case_sensitive?: boolean; max_results?: number | null } Returns: { matches: Array<{ path: string; line: number; snippet: string }> } Permission: docs:read Handler: Rust

docs.getSelection

Return the current selection range as character offsets plus the selected text.

Params: { resource_id: string; pane_id?: string } Returns: { from: number; to: number; text: string } - from === to means empty selection (caret). Permission: docs:read Handler: Frontend

docs.setSelection

Select a range of the opened file by start and end character offsets. Clamped to document length.

Params: { resource_id: string; pane_id?: string; from: number; to: number } Returns: { from: number; to: number } - the resulting (clamped) selection. Permission: docs:write Handler: Frontend

docs.insertAtSelection

Replace the current selection with the given text. If there is no selection, insert at the cursor.

Params: { resource_id: string; pane_id?: string; text: string } Returns: { cursor: number } Permission: docs:write Handler: Frontend
