Add stale-PR automation: mark stale at 3 weeks, close at 6 weeks of inactivity - #714
Conversation
Mark PRs with no activity for 3 weeks as stale, and close them after 6 weeks of total inactivity. Any activity — a comment, a push, or a maintainer removing the stale label — resets the clock. Issues are not affected. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

📝 WalkthroughWalkthroughAdded a GitHub Actions workflow that marks pull requests stale after 21 inactive days and closes them after another 21 days. The workflow excludes issues and supports scheduled or manual execution. ChangesStale pull request automation
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The workflow is a localized CI-only change, but it depends on actions/stale@v9, whose Node.js 20 runtime is scheduled to lose GitHub-hosted runner support in fall 2026; without an upgrade, stale-PR automation may stop running after that transition. The PR is mergeable with explicit owner follow-up to move to v11.0.0. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

GitHub Actions Node.js 24 runner migration Node.js 20 removal fall 2026 actions/stale v10 v11 compatibility
💡 Result:
GitHub Actions has undergone a mandatory migration from Node.js 20 to Node.js 24 during 2026 [1][2]. Key Migration Details: - Node.js 24 became the default runtime for GitHub Actions runners on June 16, 2026 [1][3]. - Node.js 20 removal is scheduled for the fall of 2026 [1][2]. After this removal, actions still configured to use Node.js 20 will fail [1][4]. - While temporary opt-out mechanisms (e.g., ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true) were available following the June 16 default-switch, these are strictly limited and will cease to function once Node.js 20 support is entirely removed from the runners [1]. Compatibility with actions/stale: - actions/stale v10.0.0 was the first release to upgrade the runtime from Node.js 20 to Node.js 24 [5][6]. - Compatibility with this version requires runners to be version v2.327.1 or later [5][6]. - actions/stale v11.0.0, released on July 28, 2026, further migrated the action to ESM (ECMAScript modules) and updated dependencies [7][8]. Users are advised to use the latest v11.x versions to ensure full compatibility with the Node.js 24 runtime environment [7][9]. Recommendation: Users should audit their workflows to ensure all actions are updated to versions that support Node.js 24 [1]. For actions/stale specifically, upgrading to v11.0.0 or later is recommended to maintain support and benefit from updated dependencies and ESM implementation [7].

Update actions/stale to v11.0.0.
actions/stale@v9 uses Node.js 20. Node.js 20 support will be removed from GitHub-hosted runners in fall 2026. actions/stale@v11.0.0 uses Node.js 24 and requires runner v2.327.1 or later.
Proposed fix

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Adds
.github/workflows/stale.yml— the repository's first GitHub Actions workflow on the code branches — usingactions/stale@v9on a daily schedule (02:30 UTC) plusworkflow_dispatchfor manual runs:stalelabel and an explanatory comment.closed-stale(reusing the repo's existing label).stalelabel (an unlabel event counts as an update, andremove-stale-when-updated: truealso auto-drops the label on new activity).days-before-issue-stale/close: -1).The workflow carries an explicit
permissions:block (issues: write,pull-requests: write— PR labels/comments go through the issues API) since the repo has no workflow-permissions baseline yet.Why
PRs accumulate without activity and there is currently no lifecycle policy or automation. This keeps the PR queue reflective of active work while giving authors a 3-week warning and an easy reset (any comment/push, or a maintainer removing the label).
Note:
schedule/workflow_dispatchrun from the default branch (develop), so the automation goes live as soon as this merges. Review activity that happens only on the internal GitLab mirror does not reset the timer — a GitHub-side comment or label removal does.Related issues
None.
API and compatibility impact
None. CI-only change; no code, build, or packaging impact.
