🔥 Full roast
🔥 14-year GitHub account with only 8 total stars, home repos full of personal configs and ignored demos, nearly half your external PRs are trivial patches, leeching big projects' star counts for clout —
penglei — 71.10/100 · SOLID (Solid · Trustworthy)
TL;DR: Long-time GitHub user with legitimate all-time contributions to major open-source projects, but home repo star count is near-zero and nearly half your external PRs are trivial window dressing on other people's code.
| Dimension | Score | Notes |
|---|---|---|
| Account maturity | 10/10 | 14.7 years registered, active across 16 contribution years, 2116 contributions last year with 0 days since last activity — veteran tenure that puts most devs to shame, even if your own repos haven’t benefited from it. |
| Original project quality | 7.2/18 | 19 original repos with only 8 total stars, max 2 stars per repo, top repo is a personal Nix config (nix-configs, quality score 0.85) — your best work is a personal dotfile collection with less traction than a niche meme account. |
| Contribution quality | 13.5/27 | 6 merged PRs out of 18 total, 5 maintainer-closed unmerged PRs, 6 self-closed external PRs, 45% maintainer rejection rate — your PR hit rate is worse than a spam cold call, and you close more external PRs yourself than get merged. |
| Ecosystem / maintenance impact | 20/20 | 12 PRs + 3 commits across 8 popular repos (all-time), including golang/go (134,885 stars) and NixOS/nixpkgs (25,283 stars) — you’ve landed real changes in some of the most widely used open-source projects on GitHub, a genuine track record that can’t be faked with config tweaks. |
| Community influence | 4.5/8 | 45 followers, 42 following — your follower-to-following ratio is nearly 1:1, you’re not exactly building a crowd, just following as many people as follow you. |
| Activity authenticity | 15.9/17 | 2116 contributions last year, 3 activity types, 16 active contribution years — activity volume is genuine and consistent, no signs of botting or fake contribution farming, even if most of it isn’t making your own repos any more popular. |
Red flags
- Quality of 9 all-time popular-repo contributions is unconfirmed: only 3 of your 15 total popular-repo contributions have file-level verification, though no negative indicators are present for the un-sampled work.
Score calibration No extra adjustment. The base score already priced in your 45% maintainer PR rejection rate and near-zero home repo star count.
Verdict Normal, trustworthy contributor with a proven track record of real changes in major open-source projects, but your strength is patching other people’s code, not building your own audience or traction for your own work.
