yob / pdf-reader
The PDF::Reader library implements a PDF parser conforming as much as possible to the PDF specification from Adobe.
yob/pdf-reader 的健康指数为 100 分中的 59 分，处于「中等」区间。 其得分最高的类别是Community & Adoption（76/100），最低的是AI Readiness（40/100）。 最近一次更新在 6 天前。 近期的大部分工作由 1 位贡献者完成。
59
总分 / 100软件健康指数
指标归入加权类别，统一采用 1–100 量表。总体分先取类别加权平均；当公开证据触发高风险司法辖区政策时，评级会按政策调整，并设置 49（有风险）的上限。AI 就绪度不计入总体分。
59
优秀85-100堪称典范；基本满足所有检验标准
良好70-84健康；仅有轻微不足
中等50-69可接受，但存在明显不足；建议进行审查
存在风险30-49存在重大薄弱环节；采用时应保持审慎
危急1-29问题严重（项目被弃置、仅有单一维护者、缺乏基本工程规范）
评分画像
每条轴代表一个类别。形状比平均值更重要——健康的对象会填满整个图形，而“一峰一谷”式画像意味着某一维度的优势正掩盖另一维度的风险。

依赖安全公告 0
该仓库未发布可被索引解析的包，因此评估的是其自身的依赖图——共 2 个包，其中也包含从不交付的开发与测试版本固定：0 个存在已知公告，0 个为直接依赖。 有 13 个无法评估——没有已解析的版本、生态系统不受支持，或不在所列包清单之内。
没有已知公告影响已评估的依赖。
公告表示依赖图中记录的版本落入某条公告的受影响范围。可达性未经分析，且依赖图包含开发与测试的版本固定——某项发现可能只涉及工具链而非交付的软件。
