syberant / ncollide
2 and 3-dimensional collision detection library in Rust
syberant/ncollide holds a health index of 19 out of 100, placing it in the Critical band. It scores highest on AI Readiness (60/100) and lowest on Community & Adoption (12/100). It was last updated 2612 days ago. A single contributor accounts for most of its recent work.
19
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.
19
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 28 is calibrated to 22 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 2612 daysautomated commits excludedreleases stalledOpenSSF Scorecard reports it unmaintained
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.
