Code Review

Review all the code changes you just made for this task. Be thorough and systematic.

What to check

1. Correctness: Are there any bugs, logic errors, or off-by-one mistakes?
2. Edge cases: What happens with empty inputs, null values, boundary conditions?
3. Error handling: Are errors caught and handled appropriately? Are error messages helpful?
4. Naming: Are variables, functions, and files named clearly and consistently?
5. Complexity: Is there unnecessary complexity? Can anything be simplified?
6. Duplication: Is there copy-pasted code that should be extracted?
7. Tests: Are there adequate tests? Do they cover edge cases and error paths?
8. Security: Any obvious security issues (hardcoded secrets, unsanitized input, etc.)?
