project-openan / a2a-t-sdk-java
project-openan/a2a-t-sdk-java holds a health index of 77 out of 100, placing it in the Good band. It scores highest on Vitality (83/100) and lowest on Security (45/100). It was last updated today. 3 contributors account for most of its recent work.
77
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.
77
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 66 is calibrated to 77 on the published index scale (record calibration 2026-08-02).

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 3
Installing maven:net.openan.a2a-t.sdk:a2a-t-llm@1.1.1 pulls in 28 packages, direct and transitive: 3 carry known advisories, of which 1 are direct dependencies.
| Package | Version | Relation | Severity | Advisories | Fixed in |
|---|---|---|---|---|---|
| com.fasterxml.jackson.core:jackson-databind | 2.20.1 | direct | high | 11 | 3.2.3 |
| com.fasterxml.jackson.core:jackson-core | 2.20.1 | indirect | high | 4 | 3.2.3 |
| org.apache.commons:commons-lang3 | 3.14.0 | indirect | moderate | 1 | 3.18.0 |
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.
