tyemirov/pinguin holds a health index of 48 out of 100, placing it in the Weak band. It scores highest on Vitality (86/100) and lowest on Community & Adoption (21/100). It was last updated 1 day ago. A single contributor accounts for most of its recent work.

overall / 100

Weak

Software health index

Metrics are grouped into weighted categories on one standardized 1–100 scale. Overall starts as their weighted mean, calibrated against the distribution of the public record so bands carry percentile meaning; when public evidence triggers the High-Risk Jurisdiction Policy, the rating is adjusted and receives an At Risk ceiling of 34.

Exceptional93-100The record's top tier (≈ top 5%); essentially all checked criteria met

Excellent80-92Strong across the board; minor gaps

Good65-79Healthy; gaps are limited and manageable

Moderate50-64Acceptable with notable gaps; review recommended

Weak35-49Material weaknesses across several areas

At Risk20-34Significant weaknesses; adoption warrants caution

Critical1-19Severe problems (abandoned, single-maintainer, no hygiene)

Score profile

Each axis is a category. The shape matters more than the average — a healthy subject fills the whole shape, while a spike-and-crater profile means strength in one dimension is masking risk in another.

The weighted overall 49 is calibrated to 48 on the published index scale (record calibration 2026-08-02).

How it's scored

9.5/35	Direct dependencies free of known advisories — 1 affected: google.golang.org/grpc v1.78.0 (critical 9.1)
0/25	Indirect dependencies free of known advisories — transitive set not separable from development and test dependencies in this scope

affected_packages	6
assessed_packages	66
unassessed_packages	0
affected_by_severity	critical 2, moderate 2, unknown 2
direct_affected_packages	1

Excluded from scoring (no data or not applicable): Indirect dependencies free of known advisories. Remaining weights renormalized. Matched 66 resolved dependencies against OSV. This repository publishes no package the index resolves, so the repository dependency graph was assessed instead. That graph mixes development and test pins with shipped dependencies, so only the declared runtime dependencies are scored; transitive findings are reported as context and excluded from the score. Reachability is not analyzed.

AI Readiness

How well is the repo equipped to be developed and maintained with AI coding agents? Carries a deliberately small weight (4%): agent tooling is a real maintenance signal, but a repository with none can still reach 100/100.

Dependency advisories 6

This repository publishes no package the index resolves, so its own dependency graph was assessed — 66 packages, which also include development and test pins that never ship: 6 carry known advisories, of which 1 are direct.

Package	Version	Relation	Severity	Advisories	Fixed in
google.golang.org/grpc	`v1.78.0`	direct	critical	4	`1.82.1`
golang.org/x/crypto	`v0.46.0`	indirect	critical	27	`0.52.0`

golang.org/x/text	`v0.32.0`	indirect	unknown	1	`0.39.0`

An advisory means the version recorded in the dependency graph falls inside an advisory’s affected range. Reachability is not analysed, and the graph includes development and test pins — a finding may concern tooling rather than shipped software.

Spotted something off in this report, or have thoughts to share? Wrong measurements, missed tooling, ideas, questions — anything is welcome. Every message is read and gets a response.

Scores are signals, not warranties. They reflect publicly visible practices on GitHub — not a code audit, and not a security guarantee.

Missing data is excluded and weights renormalized, never scored as zero. Methodology is versioned and open: metrics v2.10.0, schema v0.34.0 — full methodology · metrics wiki.
