+
+Add a scoped `CliConfig` service for customizing the built-in global flags used by CLI command runners.
+
+For example, provide an explicit list that omits `GlobalFlag.LogLevel` to remove the built-in `--log-level` flag:
+
+```ts
+import { Effect } from "effect"
+import { CliConfig, Command, GlobalFlag } from "effect/unstable/cli"
+
+const program = Command.run(command, { version: "1.0.0" }).pipe(
+  Effect.provide(
+    CliConfig.layer({
+      builtIns: [
+        GlobalFlag.Help,
+        GlobalFlag.Version,
+        GlobalFlag.Completions
+      ]
+    })
+  )
+)
+```
