You can use GitHub Actions to comment on or close issues that have been inactive for a certain period of time.
This tutorial demonstrates how to use the actions/stale action to comment on and close issues that have been inactive for a certain period of time. For example, you can comment if an issue has been inactive for 30 days to prompt participants to take action. Then, if no additional activity occurs after 14 days, you can close the issue.
In the tutorial, you will first make a workflow file that uses the actions/stale action. Then, you will customize the workflow to suit your needs.
Choose a repository where you want to apply this project management workflow. You can use an existing repository that you have write access to, or you can create a new repository. For more information about creating a repository, see Creating a new repository.
In your repository, create a file called .github/workflows/YOUR_WORKFLOW.yml, replacing YOUR_WORKFLOW with a name of your choice. This is a workflow file. For more information about creating new files on GitHub, see Creating new files.
Copy the following YAML contents into your workflow file.
name: Close inactive issues
on:
schedule:
- cron: "30 1 * * *"
jobs:
close-issues:
runs-on: ubuntu-latest
permissions:
issues: write
pull-requests: write
steps:
- uses: actions/stale@v10
with:
days-before-issue-stale: 30
days-before-issue-close: 14
stale-issue-label: "stale"
stale-issue-message: "This issue is stale because it has been open for 30 days with no activity."
close-issue-message: "This issue was closed because it has been inactive for 14 days since being marked as stale."
days-before-pr-stale: -1
days-before-pr-close: -1
repo-token: ${{ secrets.GITHUB_TOKEN }}
Customize the parameters in your workflow file:
on.schedule to dictate when you want this workflow to run. In the example above, the workflow will run every day at 1:30 UTC. For more information about scheduled workflows, see Events that trigger workflows.days-before-issue-stale to the number of days without activity before the actions/stale action labels an issue. If you never want this action to label issues, set this value to -1.days-before-issue-close to the number of days without activity before the actions/stale action closes an issue. If you never want this action to close issues, set this value to -1.stale-issue-label to the label that you want to apply to issues that have been inactive for the amount of time specified by days-before-issue-stale.stale-issue-message to the comment that you want to add to issues that are labeled by the actions/stale action.close-issue-message to the comment that you want to add to issues that are closed by the actions/stale action.Commit your workflow file to the default branch of your repository. For more information, see Creating new files.
Based on the schedule parameter (for example, every day at 1:30 UTC), your workflow will find issues that have been inactive for the specified period of time and will add the specified comment and label. Additionally, your workflow will close any previously labeled issues if no additional activity has occurred for the specified period of time.
Note
The schedule event can be delayed during periods of high loads of GitHub Actions workflow runs. High load times include the start of every hour. If the load is sufficiently high enough, some queued jobs may be dropped. To decrease the chance of delay, schedule your workflow to run at a different time of the hour.
You can view the history of your workflow runs to see this workflow run periodically. For more information, see Viewing workflow run history.
This workflow will only label and/or close 30 issues at a time in order to avoid exceeding a rate limit. You can configure this with the operations-per-run setting. For more information, see the actions/stale action documentation.
actions/stale action, like closing inactive pull requests, ignoring issues with certain labels or milestones, or only checking issues with certain labels, see the actions/stale action documentation.
