briefbound-code-structure-guard skillA
briefbound-code-structure-guard is agent-read markdown (skill) from ccdawn/codex-skills: Use when active development or explicit refactoring has concrete code-structure risk: a source file is accumulating independently changing responsibilities, a class/component/function is hard to navigate or test, repeated changes touch distant sections, or the user asks to split a giant file; do not use for line count alone, generated/vendor/migration/schema/fixture files, or cohesive modules that remain easier to maintain together..
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
# Briefbound 代码结构守卫 ## 目标 防止本轮开发继续制造多职责巨型文件。只提取稳定职责，不为压低行数制造薄包装、转发层或碎片目录。 ## Briefbound task contract - Context Boundary: 已对齐结果、当前开发 owner、目标文件、相邻模块、调用方、测试和允许写入范围。 - Output Contract: `STAY / CHECK / SPLIT` 判断；必要时完成最小职责拆分，并保持公共行为和验证证据。 - Allowed Action: 读取目标、调用方和测试；在授权 scope 内提取代码并验证；不重写模块、改变公共行为或全仓扫描。 - Success Evidence: 目标行为保持，提取单元具有可说明的职责和依赖边界，相关测试/类型/构建检查通过，且没有新增无价值抽象。 - Stop Condition: 行数是唯一信号、文件仍保持单一内聚职责、拆分会扩大用户范围、缺少行为保护，或需要公共 API/架构取舍。 - Route Out: 当前开发 owner、`briefbound-planning`、`briefbound-pr-review`、`briefbound-simplification-audit`、`briefbound-development-cleanup`、`briefbound-router` 或 BLOCKED。 ## 统一调用契约 - 只处理 Briefbound task contract 范围；不匹配时回 `briefbound-router` 或当前 owner，不接管功能、Bug、性能或普通审查。 - 用户可见内容默认中文，只报结构决策、修改、证据和风险；保留代码、命令、路径、API、skill 名和枚举；Route Out 仅以 Briefbound task contract 为准；有自然闸门时末行 `下一步建议: <一个具体动作>`，否则声明继续已授权工作。 ## 三档结构闸门 - `STAY`：职责内聚且修改位于同一行为边界。继续开发，不输出结构报告。 - `CHECK`：接近项目阈值、修改跨远距离区段或可能形成第二职责。检查 imports/exports、状态所有权、调用方和测试；证据不足即 `STAY`。 - `SPLIT`：至少存在两个独立信号，例如多个领域/层/生命周期混在一起、不同部分独立变化或复用、测试与所有权边界可分、反复修改造成导航或合并冲突。由本 skill 完成最小拆分。 优先使用项目规则；没有规则时，`函数约 75 行、类/组件约 300 行、源文件约 500 行` 只能触发 `CHECK`，不能单独触发 `SPLIT`。手写源文件超过约 800 行时优先检查，仍按职责判断。 …

How to install
mdr add ccdawn/codex-skills/briefbound-code-structure-guard@git:20260916.292b0acmdr add ccdawn/codex-skills/briefbound-code-structure-guard@sha256:34df835913c2960fPin 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.
