semantic-contract SKILL.md skillA
semantic-contract from echoyue-lp/echo-agent is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add echoyue-lp/echo-agent/semantic-contract@git:20260908.7e2cb50Pins git:20260908.7e2cb50 in mdr.lock. Pin the fingerprint instead.

提供语义材料版本 1 的唯一对象、引用、状态、风险视角和结构校验合同；仅在其它语义 Skill 要读写语义对象， 或用户要求检查语义材料格式与合同漂移时使用，不负责普通代码审查。.
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
# 语义材料合同 本 Skill 是当前仓库语义对象格式的唯一入口。它不判断业务行为是否正确，也不创建运行时存储或调度器。 结构校验需要 `uv`，或已安装 PyYAML 的 Python 3.9 及以上版本；环境不满足时报告缺口，不跳过校验。 ## 输入 - 仓库根绝对路径； - 操作：读取合同、校验现有 `semantic/`，或运行校验器自测； - 可选的另一个合同文件绝对路径，用于跨仓一致性检查。 ## 工作流 1. 需要创建、更新或解释语义对象时，读取 `references/semantic-artifact-contract.md`。 2. 需要校验磁盘材料时，在本 Skill 根目录运行 `uv run scripts/verify_semantic.py --root <仓库根绝对路径>`。 3. 修改校验器后运行 `uv run scripts/verify_semantic.py --self-test`。 4. 同时修改两个仓库的合同后，对两个合同文件做字节一致性检查；不一致时不得继续写对象。 ## 输出 返回合同版本、校验范围、错误列表、退出码和不能证明的内容。结构通过只代表材料可解析且引用完整， 不代表行为正确、审查充分或仓库没有缺陷。

How to install
mdr add echoyue-lp/echo-agent/semantic-contract@sha256:723a74cefe6c1cc4The line at the top of this page pins the label git:20260908.7e2cb50, 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.
