jaseci-labs / jac
The Jac Programming Language -- the only language you need to build anything (full stack app, device driver, video game, website, whatever). One self-contained binary; One language; Codegens to Python bytecode, JavaScript, and native machine code.
jaseci-labs/jac holds a health index of 77 out of 100, placing it in the Good band. It scores highest on Vitality (96/100) and lowest on Security (53/100). It was last updated today. A single contributor accounts 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; 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.
77
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.

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

Inputs used

| assessed_packages | 40 |
| unassessed_packages | 6 |
| affected_by_severity | critical 1, high 6, moderate 2 |
| direct_affected_packages | 1 |
Excluded from scoring (no data or not applicable): Indirect dependencies free of known advisories. Remaining weights renormalized. Matched 40 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.

OpenSSF Scorecard 4.9 / 10

Dependency advisories 9
This repository publishes no package the index resolves, so its own dependency graph was assessed — 40 packages, which also include development and test pins that never ship: 9 carry known advisories, of which 1 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 |
|---|---|---|---|---|---|
| cryptography | 46.0.5 | indirect | critical | 5 | 48.0.1 |
| starlette | 0.52.1 | direct | high | 10 | 1.3.1 |
| click | 8.3.1 | indirect | high | 1 | 8.3.3 |
| mcp | 1.26.0 | indirect | high | 3 | 1.28.1 |
| pyjwt | 2.12.1 | indirect | high | 9 | 2.13.0 |
| python-multipart | 0.0.22 | indirect | high | 12 | 0.0.31 |
| urllib3 | 2.6.3 | indirect | high | 4 | 2.7.0 |
| idna | 3.11 | indirect | moderate | 2 | 3.15 |
| pydantic-settings | 2.13.1 | indirect | moderate | 1 | 2.14.2 |
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 v0.16.0 — full methodology · metrics wiki.
How one result sits in the wider record: aggregate statistics.
