Can I use specific Python libraries like NumPy or Z3?

Yes, the solver supports any Python libraries. It even includes instructions to update your requirements.txt if you introduce new dependencies during the solving process.

Do I need an Advent of Code account to use this skill?

Yes, you must have a valid session cookie from adventofcode.com stored in an AOC_SESSION environment variable to fetch personal inputs and submit answers.

What happens if my code takes too long to run?

The skill uses a 30-second timeout for local execution. If a solution exceeds this, the skill provides performance optimization tips like memoization and specialized data structures to help you refactor.

How does the skill handle Part 2 of the daily puzzle?

The skill follows a mandatory re-fetch protocol. Once Part 1 is solved and accepted, it re-downloads the puzzle description to capture the Part 2 requirements before implementing the next solution.
