lark-whiteboard

Run lark-cli whiteboard +query with the --whiteboard-token, --output_as image, and --output path parameters. The command saves a preview image of the whiteboard to the specified file, and you can add --overwrite to replace an existing file.

Use lark-cli whiteboard +update with --input_format set to mermaid or plantuml and pass the code via --source, either from a file with @path or from stdin with -. Add --overwrite to replace all existing whiteboard content.

Fetch the document with the lark-doc +fetch command and parse the <whiteboard token="xxx"/> tag from the returned markdown. When creating new whiteboards via docs +update, the tokens are returned in the data.board_tokens field.

Code export with --output_as code only works when the whiteboard contains exactly one PlantUML or Mermaid diagram. If there are zero or multiple nodes, the response reports that code export is unavailable; use --output_as image or raw instead.

The raw OpenAPI node format suits only simple edits like changing text or colors, since hand-writing the JSON is discouraged. For complex diagrams such as architecture, swimlane, or funnel charts, generate content with the whiteboard-cli DSL and pipe it into +update.
