This is Hacker News done right for automation. It installs a Go CLI that syncs stories and comments into local SQLite, then gives you commands no other HN tool has: `since` shows exactly what moved on the front page between syncs, `velocity` tracks a story's rank trajectory over time, `controversial` finds high-debate threads by comment-to-point ratio, and `pulse` graphs topic mentions across days. The hiring commands mine multiple Who-is-Hiring threads for language trends and repeat posters. You also get offline full-text search over your growing local corpus and per-user traction stats. If you're building agents that need to track HN signal over time instead of just fetching today's top 30, the snapshot history makes queries that would otherwise require constant API hammering trivial.
