+
+  Provider tools (e.g. `anthropic.tools.webSearch`) were being converted to plain function tools in `toolsToModelTools`, stripping `type: 'provider'`, `id`, and `args`. This caused providers like Anthropic Gateway to not recognize them as provider-executed tools.

 # @workflow/builders
 
+## 5.0.0-beta.1
+
+### Major Changes
+
+- [#1662](https://github.com/vercel/workflow/pull/1662) [`89d242f`](https://github.com/vercel/workflow/commit/89d242fae2233c52153315d63e1eacb4c0ca5527) Thanks [@TooTallNate](https://github.com/TooTallNate)! - **BREAKING CHANGE**: Remove `isWorkflowSdkFile` path-based serde exclusion. Serde discovery now uses AST-level verification via SWC detect mode across all integration paths (esbuild plugin, Next.js deferred builder, Next.js loader). This allows class definitions with serde symbols in SDK packages like `@workflow/core` to be discovered and bundled correctly.

+  - Broaden `importParents` tracking to all imports (not just file extensions) so `parentHasChild()` works through bare specifier imports
+  - Include `workflow/runtime` in discovery inputs so SDK serde classes like `Run` are always discovered
+  - Bundle node_modules deps instead of externalizing with broken relative paths

Step bundles, workflow bundles, and webhook bundles now emit ESM format by default, preserving native `import.meta.url` support and eliminating the need for CJS polyfills. Fully-bundled ESM output includes a `createRequire` banner to support CJS dependencies that use `require()` for Node.js builtins. The intermediate workflow bundle (which runs inside `vm.runInContext`) remains CJS as required by the VM execution model.

+  - Use `enhanced-resolve` with ESM conditions to resolve bare specifiers from the original source file's location
+  - Only rewrite specifiers that can't resolve from the app directory (transitive SDK deps)
+  - Add `enhanced-resolve` to pnpm catalog and use `catalog:` in both packages
