Comment

Comment a pull request.

The comment action allows Mergify to post a comment on your pull request when certain conditions are met.

The comment action is a powerful tool that can provide automated responses to various events in your pull request workflow. By customizing the conditions and the message, you can create a more interactive and responsive experience for your contributors.

Parameters

Key name	Value type	Default
`bot_account`	template
Mergify can impersonate a GitHub user to comment a pull request. If no `bot_account` is set, Mergify will comment the pull request itself.
`message`	template
The message to write as a comment.
