mozilla / source-map
Consume and generate source maps.
mozilla/source-map holds a health index of 68 out of 100, placing it in the Moderate band. It scores highest on Community & Adoption (89/100) and lowest on AI Readiness (49/100). It was last updated 1 day ago. A single contributor accounts for most of its recent work.
68
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.
68
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.

Excluded from scoring (no data or not applicable): Indirect dependencies free of known advisories, No advisories left outstanding. Remaining weights renormalized. Matched 196 resolved dependencies against OSV. 6 could not be assessed — no resolved version, an unsupported ecosystem, or beyond the reported package list. 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? An independent, experimental badge — weight 0.0, so it is surfaced on its own and does not affect the overall health score.

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 9
This repository publishes no package the index resolves, so its own dependency graph was assessed — 196 packages, which also include development and test pins that never ship: 9 carry known advisories, of which 0 are direct. 6 could not be assessed — no resolved version, an unsupported ecosystem, or beyond the reported package list.
| Package | Version | Relation | Severity | Advisories | Fixed in |
|---|---|---|---|---|---|
| flatted | 3.2.7 | indirect | critical | 2 | 3.4.2 |
| brace-expansion | 1.1.11 | indirect | high | 3 | 5.0.7 |
| cross-spawn | 7.0.3 | indirect | high | 1 | 7.0.5 |
| js-yaml | 4.1.0 | indirect | high | 3 | 4.3.0 |
| minimatch | 3.1.2 | indirect | high | 3 | 10.2.3 |
| semver | 6.3.0 | indirect | high | 1 | 7.5.2 |
| underscore | 1.13.6 | indirect | high | 1 | 1.13.8 |
| ajv | 6.12.6 | indirect | moderate | 1 | 8.18.0 |
| word-wrap | 1.2.3 | indirect | moderate | 1 | 1.2.4 |
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 v1.13.0, schema v0.26.0 — full methodology · metrics wiki.
How one result sits in the wider record: aggregate statistics — npm, crates.io.
