Unclear It is unclear whether any plugin currently causes this field to be sent.
What
Some programs embed Claude Code and show its conversation in their own window. For a message that a plugin sent, these programs can now receive a plugin_prompt field. It holds the plugin's name and the text of its prompt or command, so the program can show that message under the plugin's name. A plugin is an add-on that extends Claude Code.
Why
Programs built on Claude Code can show prompts that plugins send more cleanly, labelled with the plugin they came from.
