msgpack / msgpack-cli
MessagePack implementation for Common Language Infrastructure / msgpack.org[C#]
msgpack/msgpack-cli holds a health index of 44 out of 100, placing it in the At risk band. It scores highest on Community & Adoption (64/100) and lowest on Vitality (19/100). It was last updated 736 days ago. A single contributor accounts for most of its recent work.
44
overall / 100Software health index
Metrics are grouped into weighted categories on one standardized 1–100 scale. Overall starts as their weighted mean; when public evidence triggers the High-Risk Jurisdiction Policy, the rating is adjusted and receives an At risk ceiling of 49. AI Readiness sits outside the overall score.
44
Excellent85-100Exemplary; meets essentially all checked criteria
Good70-84Healthy; minor gaps
Moderate50-69Acceptable with notable gaps; review recommended
At risk30-49Significant weaknesses; adoption warrants caution
Critical1-29Severe 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.
