I built a small CLI tool called elf to make Advent of Code workflows simpler. It helps with input fetching and caching, safe answer submission, viewing your progress, and reading private leaderboards.

Features • input fetching with caching • guardrails to prevent duplicate or invalid submissions • private leaderboard viewer in table json or model formats • status calendar and guess history viewer • optional Python API for scripting
