A GitHub App that educates users about the correct use of GitHub reactions, and deletes new reaction comments, such as +1.

How It Works

The app detects if a new comment consists solely of emojis and shortcodes used in GitHub reactions. A matching comment is either replaced with the message set in reactionComment and deleted after a day, or it is deleted immediately, if reactionComment is set to false.


  1. Install the GitHub App
  2. Create .github/reaction.yml based on the template below


Create .github/reaction.yml in the default branch to enable the app. The file can be empty, or it can override any of these default settings:

# Configuration for reaction-comments -

# Issues and pull requests with these labels accept reaction comments.
# Set to `[]` to disable
exemptLabels: []

# Replace matching comments with this message, `{user}` is a placeholder
# for the comment author. Set to `false` to disable
reactionComment: >
  :wave: @{user}, did you mean to use a [reaction]( instead?

# Limit to only `issues` or `pulls`
# only: issues

# Optionally, specify configuration settings just for `issues` or `pulls`
# issues:
#   exemptLabels:
#     - party-parrot

# pulls:
#   reactionComment: false

# Repository to extend settings from
# _extends: repo
