 ## Output Formats
 
-All built-in commands support `--format` / `-f` with `table` (default), `json`, `yaml`, `md`, and `csv`.
+Registry-backed commands, `opencli list`, and `opencli plugin list` support `--format` / `-f` with `yaml` (default), `json`, `plain`, `md`, and `csv`. Terminal rich layout is removed; text formats stay available.
 
 ```bash
 opencli bilibili hot -f json    # Pipe to jq or LLMs
+opencli bilibili hot -f plain   # Plain text response
 opencli bilibili hot -f csv     # Spreadsheet-friendly
 opencli bilibili hot -v         # Verbose: show pipeline debug steps
