Description

The contributor reputation check workflow failed in Sync risk comment because gh api does not support --arg. That caused the step to exit before it could update or dedupe the marker comment.

This update moves marker parameterization to jq (jq -r --arg marker ...) while keeping the same comment matching logic.

Pull request overview

Fixes the “Sync risk comment” step in the contributor reputation check workflow by removing the unsupported gh api --arg usage and moving marker parameterization into jq.

Changes:

• Replace gh api --jq ... --arg ... with a jq --arg ... pipeline to avoid gh api marker-argument failures.
• Add duplicate-marker cleanup logic to delete extra matching comments and keep one canonical thread.

• The comment here says it is keeping one canonical comment thread, but the loop below deletes all matching marker comments when risk drops below MEDIUM. This is a documentation mismatch that could confuse future maintenance.

              # Keep one canonical comment thread by removing all matching comments
              # when risk drops below MEDIUM.
