briefbound-bdd-tdd-development skillA
briefbound-bdd-tdd-development is agent-read markdown (skill) from ccdawn/codex-skills: Use when an already-defined new behavior or high-risk implementation contract needs a failing test before implementation, or the user explicitly requests TDD; diagnosed bugs stay with briefbound-bug-review, while simple or mechanical work uses targeted verification..
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 紧凑 BDD/TDD ## 目标 只对已明确的新行为或高风险实现契约使用最小 RED/GREEN 闭环，不承担未知根因诊断，不生成仪式性文档、逐步旁白或代理审查链。 ## Briefbound task contract - Context Boundary: 已确定的预期行为、owned surface、保护边界、测试锚点和验证命令。 - Output Contract: 最小实现、RED/GREEN 证据、相关验证和剩余风险。 - Allowed Action: 只改证明当前行为所需的生产代码与测试，不扩 scope。 - Success Evidence: RED 证明缺失/回归，GREEN 证明实现，相关回归检查通过。 - Stop Condition: 预期不清、测试不能证明目标、边界冲突、需扩范围或高风险授权。 - Route Out: 当前 owner、`briefbound-score-loop`、下一个已授权任务、`briefbound-development-cleanup`、`briefbound-pr-review`、`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` 或更具体 owner，复合任务不吞其他 owner。 - 用户可见内容默认中文；保留技术字面量；只报产出、证据与风险；Route Out 仅以 Briefbound task contract 为准；有自然闸门（需用户裁决、批准或被外部阻塞）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。 ## 模式闸门 按子任务判断，不给整个请求贴 TDD 标签。机械替换、样式/文案、普通配置、生成代码、小适配，或已有验证足够时直接轻量实现。 Bug、异常、失败测试或构建失败由 `briefbound-bug-review` 主责；可测性能目标/回归由 `briefbound-performance-engineering` 主责。两者即使使用 RED/GREEN 也不加载本 skill。只有预期行为和 owning surface 已明确的新增/变更契约，或用户明确要求 TDD，才由本 skill 主责。 分数下降、metric 未提升、candidate reject 或 online worse 是实验结果，不是 TDD RED，返回 `briefbound-score-loop`。只有预期输入输出明确的 harness/parser/schema/seed/shape/NaN/打包 bug 留在这里。 …

How to install
mdr add ccdawn/codex-skills/briefbound-bdd-tdd-development@git:20260916.292b0acmdr add ccdawn/codex-skills/briefbound-bdd-tdd-development@sha256:e805b722f55b64aaPin 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.
