+# Copilot Instructions for UiPath Python SDK
+
+Purpose:
+- Always use `**get_httpx_client_kwargs()` when creating `httpx.Client` or `httpx.AsyncClient` to ensure correct SSL, proxy, timeouts, and redirects.
+
+Guidance for Copilot:
+- When suggesting `httpx.Client(` or `httpx.AsyncClient(`, include `**get_httpx_client_kwargs()`.
+- If the user omits it, suggest the corrected version or insert a warning comment.
+
+Preferred patterns:
+```python
+import httpx
+from uipath._utils._ssl_context import get_httpx_client_kwargs
+
+client = httpx.Client(**get_httpx_client_kwargs())
+async_client = httpx.AsyncClient(**get_httpx_client_kwargs())
+
+default_client_kwargs = get_httpx_client_kwargs()
+client_kwargs = {
+    **default_client_kwargs,
+    "base_url": base_url,
+    "headers": my_headers,
+}
+client = httpx.Client(**client_kwargs)
+async_client = httpx.AsyncClient(**client_kwargs)
+```
+
+Anti-patterns (avoid):
+```python
+client = httpx.Client()              # ❌ Missing **get_httpx_client_kwargs()
+async_client = httpx.AsyncClient()   # ❌ Missing **get_httpx_client_kwargs()
+```
+
+Warning to insert if correction isn’t applied:
+```python
+# WARNING: Use httpx.Client/AsyncClient with **get_httpx_client_kwargs() for proper SSL/proxy configuration.
+```
+
