Design and test explicit human, implicit model or agent, programmatic application, bounded skill-composition, and harness activation policies for an Agent Skill catalog.
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-invocation-router"></a> # 技能调用路由器 当宿主需要可审计的激活策略，而不是一个不加区分的 `invocable` 标记时，使用此技能。 1. 阅读 `references/invocation-model.md`，对请求渠道分类。 2. 将 `assets/host-policy.json` 视为适配器配置示例进行审查，不要将其当作可移植标准。 3. 运行 `python3 scripts/simulate_invocation.py --policy assets/host-policy.json --actor ACTOR --name NAME --description DESCRIPTION --query QUERY [--explicit-name NAME] [--caller-name NAME] [--depth N] [--user-invocable true|false] [--disable-model-invocation true|false]`。 4. 对人工、应用、技能或运行框架请求，要求使用发现到的准确名称，以及相应渠道的允许列表。 5. 对技能调用方，还要求调用方身份、无循环的目标，以及有界的组合深度。 6. 对模型或自主智能体请求，先移除按执行者或已识别宿主扩展规则判定为不合格的候选项。 7. 仅对剩余描述评分。选择最匹配的合格候选项；若没有合格候选项超过阈值，则不选择。 8. 返回 JSON 决策，包含适配器、渠道、评分和策略原因。 激活只会加载指令，并不批准工具调用、文件系统修改、网络访问、秘密使用或包内脚本执行。

How to install
mdr add cluster1900/ai-engineering-from-scratch-zh/skill-invocation-router@sha256:27cdabc7012fa789The line at the top of this page pins the label git:20261018.8261244, 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.
