Code Review

This pull request introduces a minimal Flask application skeleton. A critical security vulnerability has been identified regarding the weak default SECRET_KEY configuration, which could lead to session hijacking if not properly set in a production environment. Additionally, an improvement is suggested for correctly using the python-dotenv dependency to load environment variables, making the application easier to run.

[Copilot]

Using a hard-coded default SECRET_KEY ("change-me") is unsafe because it can lead to predictable session/signature keys if the env var is omitted. Prefer failing fast when SECRET_KEY is missing, or generate a random secret for local dev while requiring an explicit value in non-debug/production environments.

Suggested change

	app = Flask(__name__)
	app.config["SECRET_KEY"] = os.environ.get("SECRET_KEY", "change-me")
	import secrets
	app = Flask(__name__)
	secret_key = os.environ.get("SECRET_KEY")
	if not secret_key:
	# In debug mode, generate a random secret key for local development.
	if os.environ.get("FLASK_DEBUG", "0") == "1":
	secret_key = secrets.token_urlsafe(32)
	else:
	raise RuntimeError("SECRET_KEY environment variable must be set in production.")
	app.config["SECRET_KEY"] = secret_key

[Copilot]

The debug flag parsing only treats the literal string "1" as true; values like "true"/"True"/"yes" will be treated as false. Consider a more permissive boolean parse to reduce configuration surprises.
