add stalebot - #277
Conversation
📝 WalkthroughWalkthroughAdded a GitHub Actions workflow that marks inactive pull requests stale after 30 days and closes them after 60 days. The workflow supports scheduled and manual runs, excludes issues and selected pull requests, and limits processing to 100 operations. ChangesStale pull request automation
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The new workflow may fail to process pull requests because it lacks required issue permissions, and updates to stale issues may remove their labels despite the stated configuration. These bounded correctness and operational issues should be fixed before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

days-before-issue-stale and days-before-issue-close to set
remove-issue-stale-when-updated to false, preventing updated stale issues from
being un-staled.
- Around line 19-20: Update the workflow job permissions alongside

actions/stale permissions issues write pull requests write issue thresholds -1 documentation
💡 Result:
The actions/stale workflow is a widely used tool for managing inactive issues and pull requests [1][2]. Because GitHub's architecture treats all pull requests as issues for the purpose of certain API operations, the action requires specific, often broad, permissions to function correctly [1][3][4]. Required Permissions To operate correctly, the action generally requires write access to both issues and pull requests, even if you are only attempting to manage one or the other [1][3][4]. At a minimum, many configurations require the following in your workflow file: permissions: actions: write issues: write pull-requests: write If you enable the delete-branch option, you must also include contents: write [1][5][6]. Key Considerations for Permissions 1. API Limitations: The action initiates by calling the List repository issues API, which returns a combined list of issues and pull requests [3][4]. Even in repositories where Issues are disabled, the workflow will often fail if it lacks at least issues: read or issues: write permissions because it cannot properly enumerate the items to process [3][4]. 2. "Resource not accessible": If you receive an error stating Resource not accessible by integration when the action attempts to label, comment on, or close an item, it almost always indicates that the workflow lacks the necessary write permissions for issues or pull-requests [7][4]. Threshold Documentation The behavior of the stale action is governed by several threshold settings, which can be configured in your workflow's with block [8][9]: - days-before-issue-stale / days-before-pr-stale: The number of days of inactivity before an item is marked as stale [8][9]. - days-before-issue-close / days-before-pr-close: The number of days to wait after an item has been marked as stale before it is automatically closed [8][9]. - operations-per-run: A critical setting to prevent hitting GitHub API rate limits; it defaults to 30 but can be adjusted if your repository has many items to process [8][2]. For complex setups, such as those involving branch protection rules or stacked pull requests, additional permission or configuration tuning may be necessary to resolve sporadic "Insufficient permissions" errors [5]. Always ensure your workflow includes the recommended permissions provided by the official action repository to avoid common runtime failures [1][7][2].

actions/stale v11 remove-issue-stale-when-updated default behavior days-before-issue-stale -1
💡 Result:
In the actions/stale action, the default behavior for the remove-issue-stale-when-updated option is true [1]. When this is set to true (or left as the default), the action will remove the stale label from an issue if the issue is updated (e.g., a new comment is added) after it has been marked as stale [2][1][3]. Regarding the days-before-issue-stale input, there is no hardcoded numeric default value specific to issues in the action itself; rather, it is designed to override the general days-before-stale setting [2][4]. The general days-before-stale option has a default value of 60 days [2]. If days-before-issue-stale is not explicitly provided in your workflow configuration, the action will fallback to the value set in days-before-stale [2][4].

Disable issue-side un-staling.
remove-issue-stale-when-updated defaults to true, so an updated stale issue can lose its stale label despite the -1 thresholds. Set it to false.
