sammcj / mermaid-check
Native Golang Mermaid Parser and Linter
sammcj/mermaid-check holds a health index of 60 out of 100, placing it in the Moderate band. It scores highest on AI Readiness (89/100) and lowest on Community & Adoption (37/100). It was last updated 7 days ago. 2 contributors account for most of its recent work.
60
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.
60
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.

Dependency advisories

How it's scored

| 0/25 | Indirect dependencies free of known advisories — transitive set not separable from development and test dependencies in this scope |

Inputs used

| assessed_packages | 4 |
| unassessed_packages | 0 |
| affected_by_severity | unknown 1 |
| direct_affected_packages | 0 |
Excluded from scoring (no data or not applicable): Indirect dependencies free of known advisories, No advisories left outstanding. Remaining weights renormalized. Matched 4 resolved dependencies against OSV. 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.

Direct dependencies 1
| Registry | Package | Version constraint | Manifest |
|---|---|---|---|
| Go | github.com/fatih/color | v1.19.0 | go.mod |
All dependencies 4
Full resolved dependency set from the GitHub dependency graph: 1 direct and 3 indirect (transitive) packages. The transitive closure is complete when the repository commits a lockfile.
| Registry | Package | Version | Relation |
|---|---|---|---|
| Go | github.com/fatih/color | v1.19.0 | direct |
| Go | github.com/mattn/go-colorable | v0.1.14 | indirect |
| Go | github.com/mattn/go-isatty | v0.0.22 | indirect |
| Go | golang.org/x/sys | v0.43.0 | indirect |
Dependency advisories 1
This repository publishes no package the index resolves, so its own dependency graph was assessed — 4 packages, which also include development and test pins that never ship: 1 carry known advisories, of which 0 are direct.
| Package | Version | Relation | Severity | Advisories | Fixed in |
|---|---|---|---|---|---|
| golang.org/x/sys | v0.43.0 | indirect | unknown | 1 | 0.44.0 |
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.

}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 v0.27.0 — full methodology · metrics wiki.
How one result sits in the wider record: aggregate statistics — Go.
