Build a bounded Agent Skill catalog across explicit discovery scopes and report collisions before loading instruction bodies.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<a id="skill-catalog-builder"></a> # 技能目录构建器 当智能体宿主需要跨多个技能目录进行确定性发现时，使用此技能。 1. 阅读 `references/discovery-contract.md`。 2. 审查 `assets/scope-policy.json` 中的宿主策略示例；不要假设其中的顺序普遍适用。 3. 运行 `python3 scripts/build_catalog.py project=PATH user=PATH`，按优先级从高到低列出范围。 4. 激活技能前，检查 JSON 中的 `collisions` 和 `omitted` 数组。 5. 仅加载所选 SKILL.md 的正文。只有正文明确引用时，才加载直接引用文件。 发现阶段绝不执行包内脚本。绝不依靠偶然的文件系统顺序，从优先级相同的重复项中做选择。 返回目录预算、选中条目、冲突解决结果和省略项。

How to install
mdr add cluster1900/ai-engineering-from-scratch-zh/skill-catalog-builder@sha256:86257c0b357c6759The line at the top of this page pins the label git:20261018.7f40741, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
