+- Use type hints for all functions, return values, and dataclass fields
+- Use `httpx.AsyncClient` for HTTP requests; do not use `requests`
+  or `aiohttp`
+- Use `await asyncio.sleep()` for delays; do not use `time.sleep()`
+- Return dataclasses for HTTP responses, not raw dictionaries
+- Follow PEP 8 style conventions

+# Prompts
+
+Copy-paste these into Cursor and Windsurf in order while following the tutorial.
+
+## 1. Set up the project
+
+```
+Set up a Python project in this directory following standard Python
+packaging conventions:
+- Create a virtual environment
+- Install httpx==0.28.1 and pytest==9.0.2
+- Add a tests/ directory
+- Use the directory name as the package name
+- Only include the dependencies explicitly listed here
+```
+
+## 2. Write the async fetch function
+
+```
+Create a file called `fetcher.py` and write an async function
+called fetch_json that:
+- Takes a URL string and an optional integer max_retries (default 3)
+- Uses httpx.AsyncClient to fetch JSON from the URL
+- Retries up to max_retries times with exponential backoff (1s, 2s, 4s)
+  on any httpx.HTTPError
+- Returns the JSON response as a typed dataclass called FetchResult
+  with fields: url (str), status_code (int), and data (dict[str, Any])
+- Uses proper type hints throughout
+```
+
+## 3. Generate tests
+
+Before sending this prompt, open `fetcher.py` and replace
+`await asyncio.sleep(delay)` with `time.sleep(delay)`, then add
+`import time` at the top. Save the file.
+
+```
+Create tests/test_fetcher.py with pytest tests for fetch_json that:
+- Test successful fetch returns correct FetchResult
+- Test fetch retries twice then succeeds
+- Test fetch raises after exhausting retries
+- Test two concurrent fetches complete in <4s
+  (one with 1s+2s retry delays, one instant)
+- Test fetch can be cancelled during retry delay
+Use httpx.MockTransport for mocking.
+```
+
+## 4. Plan-mode prompt
+
+Switch each editor to its Plan mode before sending:
+
+```
+Add a retry_budget parameter to fetch_json that limits the total
+cumulative wait time across all retries.
+```
+
+## 5. Autocomplete starter snippet
+
+Type this into a file and let each editor complete it:
+
+```python
+@dataclass
+class RetryMetadata:
+    attempts_made: int
+# ...
+```
+
+## 6. Manual review (Windsurf Ask mode)
+
+```
+Review fetcher.py for bugs and lint issues and summarize what you find.
+```
