/auto-approve-konflux-prs

Name

utils:auto-approve-konflux-prs

Synopsis

/utils:auto-approve-konflux-prs <target-repository>

Description

The command automates the approval of open PRs created by the red-hat-konflux[bot] for the given repository.

It filters all open PRs from the given repository, checks whether the PR already has /lgtm and /approve comments, verifies that all required checks (CI jobs or other mandatory checks) have passed, and if any labels/comments are missing and all checks succeed, posts /lgtm and /approve comments to trigger approval.

This ensures that PRs are only auto-approved if all required checks succeed and the author is red-hat-konflux[bot], reducing the risk of approving failing or unauthorized changes.

Arguments

• $1 – target-repositories (required): GitHub repository in OWNER/REPO format.
  • Example: openshift/multiarch-tuning-operator.

Implementation

The command executes the following workflow:

1. Restrict Author

The command only processes PRs authored by red-hat-konflux[bot]. If a PR from any other author is encountered, it reports an error such as below:

⚠️ Only PRs from red-hat-konflux[bot] can be automatically processed

and exits.

2. Get Open PRs

Fetch all open PRs authored by red-hat-konflux[bot] for the specified repository:

gh pr list --repo <target-repository> --author app/red-hat-konflux --state open --json number,title,baseRefName,labels

• Extract: number,title,baseRefName,labels

3. Check CI Status and Labels

For Each PR::

1. Fetch detailed PR information:

gh pr view <PR_NUMBER> --repo <target-repository> --json statusCheckRollup,labels

• Extract: statusCheckRollup,labels
• Handle errors: If PR is inaccessible, log warning and skip

2. Verify all required checks:

• Verify all required checks have "conclusion": "SUCCESS"
• If any check has failed or is pending(except one pending tide job), skip adding /lgtm or /approve and log:

⚠️ Skipping PR #<PR_NUMBER>: CI checks not all passed

3. Inspect labels:

   • Check for lgtm label
   • Check for approved label

4. Add missing labels via comments:

   • If /lgtm is missing, post a comment /lgtm
   • If /approve is missing, post a comment /approve
   • If both are missing, post a single comment containing both commands.

5. Log each action:

✅ Added /lgtm and/or /approve to PR #<PR_NUMBER>: <PR_TITLE> (merge into <MERGE_BRANCH>)

Return Value

• Claude agent text: Summary of processed PRs and actions taken.
• Side effects:
  • Comments posted to PRs to trigger /lgtm and /approve.
  • Progress updates for multiple PRs.

Examples

1. Process all open PRs from red-hat-konflux[bot] in a repository:
