+- b521571: Added `runCli` for creating executable CLI packages from a fixed collection of directly imported CLI modules, with validation for conflicting command paths. The single-module `runCliModule` helper is now deprecated.

+## Custom CLIs
+
+Use `runCli` to create an executable CLI from a fixed set of directly imported modules:
+
+```ts
+import { runCli } from '@backstage/cli-node';
+import buildModule from '@backstage/cli-module-build';
+import testModule from '@backstage/cli-module-test-jest';
+import packageJson from '../package.json';
+
+runCli({
+  modules: [buildModule, testModule],
+  name: packageJson.name,
+  version: packageJson.version,
+});
+```
+
+The caller owns module selection. The runner does not discover modules or apply module overrides.
