ZhanYF — 61.70/100 · NPC (Average · Unremarkable)
TL;DR: A low-profile contributor whose handful of legitimate high-star PRs can't hide a barren home repo portfolio and a follow-simp ratio that prioritizes visibility over actual output.
| Dimension | Score | Notes |
|---|---|---|
| Account maturity | 8.8/10 | ~5 years old account with 6 active contribution years, though 47 days of radio silence suggests your open-source habit runs on a battery that's constantly dying |
| Original project quality | 5.7/18 | 10 original repos, 1 combined star, only veritymobile (quality score 0.8) has any real content; the rest are config dumps, personal bookmarks, or digital dead weight |
| Contribution quality | 17.4/27 | 15 of 17 PRs merged, with 1 maintainer-closed unmerged PR and 1 self-closed external PR; 6 recent merged PRs are trivial fixes, 54% of external PRs orbit docs/site/config tweaks, so your review queue luck is better than your PR substance |
| Ecosystem / maintenance impact | 18.2/20 | 7 PRs and 9 commits across 6 popular repos totaling ~48k stars, with 3 verified core code contributions to seL4, capnproto and evremap — this is the only part of your profile that doesn't look like resume padding |
| Community influence | 1.7/8 | 2 followers, 21 following, a 10.5:1 follow-to-follower ratio that makes your influence smaller than the typo you fixed in DearPyGui's demo script |
| Activity authenticity | 9.9/17 | Only 6 contributions all last year, 3 activity types total, and 47 days of no recent commits — your open-source presence is sparser than your repo star counts |
| Red flags |
- Your 10 original repos have a combined 1 star, with only veritymobile containing meaningful content; the rest are config dumps, personal bookmarks, or empty shells.
- 54% of your recent external PRs are docs/site/examples/config tweaks rather than core engineering work, and 6 of your 15 recent merged PRs are trivial fixes (typos, broken links, config updates) on high-star projects.
- You follow 21 accounts but have only 2 followers, a 10.5:1 ratio that signals you're curating other people's work far more than building your own audience.
- 47 days with no recent contributions, and only 6 total contributions in the last year, makes your active contributor status feel performative at best. Score calibration No extra adjustment. The base score already accounts for your sparse home turf, docs-heavy external PRs, and low community footprint, with no positive bump for your top original repo since its 1 star reflects almost no real user adoption. Verdict Normal average contributor with a handful of legitimate high-star PRs, but no meaningful personal project footprint to back up your GitHub presence — you're the open-source temp worker who shows up for small tasks at big companies but has no office of your own.
