🔥 9-year OSS veteran who channels 90% of his PRs into his own CTF team site, can't even hit 130 total stars across all his niche waifu tools, and probably leverages his Web3 anti-fraud expertise to avoi

sahuang — 78.60/100 · SOLID (Solid · Trustworthy)

TL;DR: Genuine niche open-source contributor with a strong track record of substantive contributions to high-star projects and personal CTF/community tools, no farming or red flags; low star count on personal projects stems from niche focus rather than low quality.

DimensionScoreNotes
Account maturity10/10Registered 9.33 years, active across 10 contribution years
Original project quality9.9/1811 non-empty original repos, total 128 stars, top project priconne-rainbow-fart has 50 stars; niche CTF/anime tool focus limits mass star appeal
Contribution quality24.9/27145 merged PRs out of 149 total PRs; 0 maintainer-closed unmerged PRs, 4 author-closed external PRs, 0 author-closed own-repo PRs; only 3 trivial PRs in recent 50 PR sample
Ecosystem / maintenance impact11.5/204 substantive PRs to popular repos all-time: 2 PRs to ★44,987 milvus, 2 PRs to ★491 milvus-sdk-java (contributions made during tenure at Milvus)
Community influence6.8/8311 followers, 57 following (healthy ~5.5:1 follower ratio, no follow-farming behavior)
Activity authenticity14.5/17534 contributions in the last year, last activity 4 days ago, no templated PR flood (templated PR ratio 7%, flood suspect = false)
Red flags: None
Manual adjustment: +1, the original project quality subscore is underpenalized for niche project focus: CTF challenge repos, anime voice packs, and game bots have inherently lower mass appeal, so low star counts do not reflect low project quality.
Verdict: Normal, recommended for collaboration on CTF, Web3 security, or niche tooling projects.
