🔥 Full roast
🔥 I dug through every metric and found literally nothing to roast: your Equinox/Diffrax/jaxtyping trio defines the JAX ecosystem, 777 merged PRs with zero filler, only 2 follows so no simp-league follow
patrick-kidger — 100.00/100 · GOD (Legendary · Hall of Fame)
TL;DR: A legendary open-source maintainer who built the core JAX scientific computing stack (Equinox, Diffrax, jaxtyping) from scratch, with zero detectable filler work, no PR farming, and a contribution volume that makes most professional devs look like part-timers. The only flaw is that he left me nothing to roast.
| Dimension | Score | Notes |
|---|---|---|
| Account maturity | 10/10 | 8.62 years old, 10 years of active contributions, last active today |
| Original project quality | 17.1/18 | 13,567 total stars across 49 non-empty original repos, top repo Equinox scores 0.95 quality with 2,914 stars; no star inflation, no profile/config repos gulling up the star count |
| Contribution quality | 29/27 | 777 merged PRs out of 838 total, only 2 maintainer-closed unmerged PRs, 11 self-closed external PRs, 32 self-closed own-repo PRs; recent external PRs are 100% substantive, no Hacktoberfest-style filler work |
| Ecosystem / maintenance impact | 19.7/20 | 619 PRs + 1,806 commits into 15 popular repos (including 33 PRs/20 commits to JAX itself, 326 PRs/847 commits to Equinox); the 568 contributions without file-level samples are just coverage gaps, not quality issues, and the all-time totals are massive |
| Community influence | 8/8 | 2,904 followers vs only 2 following, zero follower farming, no simp-league follow-for-follow schemes; the follower count is earned entirely from shipping usable libraries |
| Activity authenticity | 16.9/17 | 1,768 contributions in the last year, active across 4 activity types, last active today, no bot-like contribution spikes or templated PR flooding |
Red flags None detected. No PR farming, no trivial external contribution spam, no star inflation, no templated PR flooding, no suspicious closure patterns.
Score calibration No extra adjustment. The base score accurately reflects the account's outstanding contribution quality and volume, with no overlooked signals requiring a bump or haircut.
Verdict Prioritize. This is a top-tier open-source contributor whose work is foundational to the JAX scientific computing ecosystem; worth engaging, supporting, or featuring without reservation.
