+# kilocode_change - new file
+# Standalone smoke test — checks out kilo-bench and runs a small set of
+# Harbor eval tasks against the latest published CLI (or a specific version).
+#
+# Tasks:  hello-world (~$0.01), log-summary-date-ranges (~$0.13)
+# Expected total: < $0.50, < 15 min wall clock
+#
+# Triggers:
+#   - workflow_dispatch: manually from Actions tab (optionally pass a CLI version)
+#   - push to main: automatically after every merge
+#
+# Required secrets:
+#   KILO_API_KEY         — Kilo Gateway key
+#   KILO_ORG_ID          — Kilo org ID
+#   BENCH_GITHUB_TOKEN   — PAT with contents:read on Kilo-Org/kilo-bench (private repo)
