A GitHub App that deletes reaction comments, such as +1, and encourages the use of GitHub reactions.

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 for the intended repositories
  2. Create .github/reaction.yml based on the template below

If possible, install the app only for select repositories. Do not leave the All repositories option selected, unless you intend to use the app for all current and future repositories.


Create .github/reaction.yml in the default branch to enable the app, or add it at the same file path to a repository named .github. 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, `{comment-author}` is an
# optional placeholder. Set to `false` to disable
reactionComment: >
  :wave: @{comment-author}, 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
