[route] 'calculate_average crashes on an empty list, where is the bug?'
   -> kind=bug (The user reports that calculate_average crashes on an empty list and asks where the bug is. A crash on a valid input (empty list) is a defect in the code, most likely a division by zero or an unguarded index access, so it is classified as a bug report.)
   -> This one's already fixed — not a live bug. In `src/utils.py`, the original defect was that `calculate_average` divided `total / len(numbers)` unconditionally, causing a `ZeroDivisionError` on `[]`. The fix (already in place, per CHANGELOG.md) adds an `if not numbers: return 0.0` guard before the division, so the empty-list case short-circuits and never reaches `len(numbers)` as a divisor.

[route] 'What is the difference between a list and a tuple in Python?'
   -> kind=question (The user is asking a conceptual question about Python: the difference between lists and tuples. It is not reporting a defect, and it is not requesting documentation changes. It seeks an explanation, so it is classified as a question.)
   -> A list is mutable (can be changed after creation) and defined with `[]`, while a tuple is immutable (cannot be changed after creation) and defined with `()`.

Let me take a quick look at the project files to ensure accuracy.

---

- **Overview**: This project is a small Python demo built to showcase the Claude Agent SDK, containing a simple application (`src/app.py`) and a set of helper functions (`src/utils.py`).
- **Project Structure**: The `src/` directory holds the core application code (`app.py`) and shared utility functions (`utils.py`), while `tests/` contains the corresponding unit tests (`test_utils.py`).
- **Usage**: Run the app directly with `python src/app.py`, or import the utilities in your own code with `from src.utils import <function_name>` and call them as needed.
- **Testing**: Run the full test suite from the project root using `pytest tests/`.
- **Known Issues / Notes**: `src/app.py` intentionally contains a SQL injection vulnerability as a deliberate, educational flaw for demo purposes and should **not** be treated as production-ready code.

[vote] votes=[False, False, False] -> majority safe=False
   - safe=False: app.py has a SQL injection vulnerability (f-string interpolated query in find_user) and a hardcoded live API key, both unsafe for production.
   - safe=False: It hardcodes a live API key in source and builds SQL via unparameterized string interpolation, exposing it to credential leakage and SQL injection.
   - safe=False: It hardcodes a live API key in source and builds a SQL query via f-string interpolation, exposing a secret and a SQL-injection vulnerability.
