tokio-rs / valuable
tokio-rs/valuable holds a health index of 29 out of 100, placing it in the At Risk band. It scores highest on Community & Adoption (66/100) and lowest on Vitality (24/100). It was last updated 106 days ago. A single contributor accounts for most of its recent work.
29
overall / 100Software 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.
29
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).

Abandonment alert
Work has arrived and nobody has attended to it
no human commit in 563 daysautomated commits excludedpull requests left unansweredissues left unansweredOpenSSF Scorecard reports it unmaintainedcontinuous integration brokenOverall rating: At Risk ceiling
Silence alone is never the finding — a small, finished library may need no commits for years. This alert requires both: no human commit for a long time, and obligations the project is visibly not discharging. Automated commits do not count as maintenance.

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.

When each star and fork was added, collected from GitHub and bucketed by day. Cumulative growth sits directly above the daily additions it is made of, so the two read against each other: steady organic accretion looks nothing like an abrupt, short-lived burst. Where that difference is measurable, it is reported as growth authenticity.

Dependency advisories 2
Installing crates:valuable@0.1.1 pulls in 60 packages, direct and transitive: 2 carry known advisories, of which 0 are direct dependencies.
| Package | Version | Relation | Severity | Advisories | Fixed in |
|---|---|---|---|---|---|
| atty | 0.2.14 | indirect | low | 3 | — |
| serde_cbor | 0.11.2 | indirect | unknown | 1 | — |
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.

}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 v2.3.1, schema v0.30.0 — full methodology · metrics wiki.
How one result sits in the wider record: aggregate statistics — crates.io.
