lld-writer is agent-read markdown (skill) from testany-io/testany-agent-skills: Write LLD, Low-Level Design, 写详细设计。Use when: PRD/HLD/API Contract 完成后需要写模块设计、接口设计、实现级技术方案。 也用于既有相关文档的有限增量更新。.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# LLD Writer 执行前读取 [工作流执行约定](../../references/workflow-execution.md)：先取证再提问、按实际工具能力回退，并从本次安装位置定位资源。 > **语言规则**：默认跟随用户输入语言；用户显式指定时以用户指定为准；不要因为本 `SKILL.md` 是中文而强制输出中文；`TRACEABILITY-METADATA` 的字段名、枚举值、ID、comment markers 始终保持英文。若本 skill 使用模板或派发子任务，继续传递同一个 `output_language`。详见 `../../references/language-policy.md`。 你是一个低层设计（LLD）写作助手。你的目标是把 HLD/Contract 的决策落地为可实现的设计细节，并通过模块化模板确保不漏关键工程约束。 ## 先选工作模式 - `formal_design`：用户要求完整新功能文档或正式全量准出，执行下文完整流程、模板、追溯和适用门禁。 - `bounded_change`（`amendment`）：在已有有效基线和明确授权的变更范围内，读取 [有限增量规则](../../references/document-amendments.md)，直接执行“读取基线与授权 -> 核对影响边界 -> 修改获授权增量 -> 检查差异与验证 -> 交付范围限定的结果”。不回补全套历史文档，不把草稿或自检升级为批准。 - 模式由实际职责、信任、契约、失败语义与批准范围决定，不按行数/文件数判断。“两行修改”改变权限边界仍需对应有权 Owner 决策。 下文全量模板、全局覆盖矩阵与整套前置文档是 `formal_design` 的要求；有限增量沿用既有工件格式、有效批准及相关追溯，不因缺某种历史文件格式自动改成新项目启动。 ## 核心原则 | 原则 | 说明 | |------|------| | **承接 PRD/HLD/Contract** | LLD 只能细化，不得新增边界或改写契约 | | **Contract 是事实源** | LLD 只引用，不重定义接口 | | **基于证据** | 技术现状/既有能力必须有依据；缺失就 AskUserQuestion | | **模块化组合** | LLD = Core + Add-ons + Profile + Guardrails | | **Guardrails 最高优先级** | 项目约束文档优先于个人偏好 | | **先做 Guardrails trigger check** | 若本次 LLD 反向暴露项目级约束缺口，先判断是否必须更新 Guardrails | | **复用优先** | 优先复用已有模块/共享服务/第三方方案 | …

How to install
mdr add testany-io/testany-agent-skills/lld-writer@git:20260914.a55b8c5mdr add testany-io/testany-agent-skills/lld-writer@sha256:0065b568cfc55b12Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
