Utils

Script	Purpose
.github/utils/utils.sh	Includes comment_issue (type 15), set_size_label (type 21), set_pr_milestone (type 22), set_issue_milestone (type 23), move_pr_issue_to_next_milestone (type 24), delete_actions_cache (type 30), get_job_url (type 44)
.github/utils/webhook_utils.sh	Webhook message helpers

utils.sh Type Quick Reference

Type	Operation
15	Comment on issue
21	Set PR size label
22	Set PR milestone
23	Set issue milestone
24	Move PR/issue to next milestone
30	Delete actions cache
44	Get GitHub Actions job URL

Common Tasks

1. Change PR size label rules

bash ./.github/utils/utils.sh --type 21 \
    --github-repo "${{ github.repository }}" \
    --github-token "${{ env.GITHUB_TOKEN }}" \
    --pr-number "${{ github.event.pull_request.number }}"

The rule logic lives in utils.sh function set_size_label, typically classifying diffs into size/XS through size/XXL.

2. Add a new cherry-pick target branch

Configure target branches and trigger labels in pull-request-cherry-pick-auto.yml. Notes:

• Trigger labels usually look like cherry-pick release-x.y.
• On failure, the workflow creates a comment to alert maintainers.

3. Adjust issue auto-comments

comment-issue.yml calls utils.sh --type 15. To change comment content, update the comment_issue function or workflow parameters.

4. Delete actions cache

bash ./.github/utils/utils.sh --type 30 \
    --github-repo <repo> \
    --github-token <token>
