+# Cross-repository references for the apify-factory review (apify/ai-developer, `review-references`).
+version: 1
+
+instructions: |
+  This repository is the Apify SDK for Python, the library for building Actors in Python. It is built
+  on the Python API client and on Crawlee for Python, and it mirrors the Apify SDK for JavaScript. For
+  every behaviour the pull request adds or changes, check three things: that it uses the API client's
+  methods, models and exceptions as they are (the SDK defines none of its own), that it fits the
+  Crawlee interface it builds on, and that it matches what the JS SDK does for the same operation
+  (ignore differences caused by different language idioms and style). Back every finding with the
+  reference file and line; the review links them to the commit it read.
+
+references:
+  - repository: apify/apify-client-python
+    instructions: |
+      The API client this SDK calls. Compare every client call the pull request makes or changes with
+      the method it calls: parameters, defaults, return shape, exceptions.
+  - repository: apify/crawlee-python
+    instructions: |
+      The framework this SDK extends: configuration, storage clients and their models, storages, events,
+      request loaders, the service locator. Compare what the pull request implements or overrides with
+      the interface or base class it builds on.
+  - repository: apify/apify-sdk-js
+    instructions: |
+      The JS SDK this one mirrors. Compare the changed Python behaviour with its JS counterpart:
+      parameters and defaults, what it returns, and how it handles errors.

 - **Errors** — `apify.errors` only re-exports the exceptions from `apify_client.errors`; the SDK defines no error classes of its own, and API calls raise the client exceptions unchanged.
 - Response and data models (`Run`, pricing info, webhook representations) come from `apify-client`; the SDK doesn't define its own. The platform env-var enums (`ApifyEnvVars`, `ActorEnvVars`) live in `apify._consts`.
