Hi @riprasad,

Image pull request is created from compared branch ‘depbot’ to base branch. Typically workflow can be skipped with below methods:

1. Use on.pull_request.branches/branches-ignore to limit the base branch. code sample as below:

on: 
  pull_request:
    branches-ignore: 
      - master                                 # pull request to master branch, event will NOT be triggered.

2. Add if expression in worklfow yaml, eg: skip the job if pull request comes from user dephot. The limitation is the workflow will be listed in the actions tab but the job is skipped.

on: [pull_request]
jobs:
  job1:
    if: github.actor!= 'depbot'   # ignore the pull request which comes from user depbot.

Note: you can change the if expression according to your needs.

3. If you don’t like whatever pull_request from depbot branch, you can comment out the pull_request event or delete it from yaml file, or even disable all github actions from repo setting- Actions tab.

You can pick one according to your needs.

Thanks.
