+Automated PR review script for sonic-net/sonic-mgmt.
+
+This script finds all open PRs filed in the last N days (default: 3),
+reviews each one against the standard PR template requirements, and
+posts a comment summarizing any missing or incomplete sections.
+
+A comment is only posted once per PR (idempotent: won't re-comment if
+the bot has already reviewed this PR).
+
+Required environment variables:
+  GITHUB_TOKEN     - GitHub token with read/write access to pull requests
+  GITHUB_REPOSITORY - Repository in "owner/repo" format (set by GitHub Actions)
+
+Optional environment variables:
+  DAYS_BACK        - Number of days to look back (default: 3)
