 # @tailor-platform/function-types
 
-## Usage
+**Deprecated.** These types are now built into [`@tailor-platform/sdk`](https://www.npmjs.com/package/@tailor-platform/sdk), which exposes the same `tailor.*` / `tailordb.*` runtime surface plus typed wrappers you can import directly instead of relying on ambient globals. New projects should use `@tailor-platform/sdk` instead of this package; existing projects should migrate using the steps below.
+
+This package will no longer receive updates for new runtime APIs (e.g. it never picked up `tailor.aigateway.get()`, while `@tailor-platform/sdk` will keep gaining new runtime APIs).
+
+## Migrating to `@tailor-platform/sdk`
+
+1. Add `@tailor-platform/sdk` and remove this package:
+
+   ```sh
+   npm i -D @tailor-platform/sdk
+   npm uninstall @tailor-platform/function-types
+   ```
+
+   If your project already depends on `@tailor-platform/sdk` (e.g. for `tailor.config.ts`, resolvers, or workflows), you can skip the install step.
+
+2. Update `tsconfig.json` to load the runtime globals from the SDK instead:
+
+   ```diff
+     {
+       "compilerOptions": {
+   -      "types": ["@tailor-platform/function-types"]
+   +      "types": ["@tailor-platform/sdk/runtime/globals"]
+       }
+     }
+   ```
+
+3. No other code changes are required. The global `tailor.*` and `tailordb.*` identifiers keep the same names and shapes (including the legacy capitalized `Tailordb.Client`, which `@tailor-platform/sdk` also keeps around for compatibility with this package).
+
+### Prefer typed imports over ambient globals (optional)
+
+Instead of relying on the ambient `tailor` / `tailordb` globals, `@tailor-platform/sdk/runtime` exposes the same APIs as regular imports, which is easier to trace and doesn't require the `tsconfig.json` `types` change above:
+
+```typescript
+import { iconv, secretmanager, idp, workflow, context, authconnection, file } from "@tailor-platform/sdk/runtime";
+
+const secret = await secretmanager.getSecret("my-vault", "API_KEY");
+```
+
+### Known gap: `tailor.aigateway`
+
+`@tailor-platform/sdk` does not yet expose a runtime equivalent of `tailor.aigateway.get(name)`. If your code uses it, keep this package installed alongside `@tailor-platform/sdk` for that one namespace until the SDK adds support, or reach out to the SDK team if you need this migrated sooner.
+
+## Legacy usage (this package)
 
-Install package.
 ```sh
 npm i -D @tailor-platform/function-types
 ```
 
-Add types to `tsconfig.json`.
-```
+```json
 {
-  ...
   "compilerOptions": {
-    ...
     "types": ["@tailor-platform/function-types"]
   }
 }
