A GitHub App that deletes +1 comments, 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 special 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
