+# Monthly SKU catalog refresh.
+#
+# Runs on the 1st of each month at 09:00 UTC and on manual dispatch.
+#
+# Does two things:
+#   1. `--refresh`: pulls latest PAYG prices from Oracle's public API,
+#      updates kb/pricing/oci-sku-catalog.yaml, and opens a PR if anything
+#      changed.
+#   2. `--discover`: reports SKUs present in the API but absent from the
+#      catalog (filtered to serviceCategory values already curated).
+#      If new SKUs are found, opens a Gitea issue listing them by category
+#      for manual review.
+#
+# Token:
+#   Uses the auto-provisioned secrets.GITHUB_TOKEN (Gitea Actions provides this
+#   per-run, scoped to this repo, GitHub-Actions-compatible). No manual secret
+#   configuration required. The explicit `permissions:` block below grants the
+#   scopes needed to push a branch, open a PR, and open an issue.
