Star Trajectory

Classifies GitHub repos into growth phases (launch, accel, sustain, maturity) and projects whether they'll hit 100 stars in 48 hours, all from anonymous API calls with zero dependencies. Exposes a single classify_repo tool over stdio that returns phase, velocity metrics, driver vs burst signals, and a three-level lean (HIT/BORDERLINE/MISS) instead of fake probabilities. The project scores itself publicly in PREDICTIONS.md with a running track record of hits and misses. Pairs naturally with fake-star-audit to filter out purchased growth. Useful when you're triaging trending repos in Claude and want transparent heuristics instead of a black box, or when you need to know if a project's momentum is real before recommending it.
