Use when a change touches an external contract surface - REST/GraphQL endpoints, request/response schemas, DB schema, events, or CLI arguments - and needs design, breaking-change analysis, versioning, or a migration path; do not use for general implementation planning, code review, or feature coding.
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
# Briefbound API Contract ## 目标 保护对外契约面：接口、schema、事件和 CLI 参数的每一次变更都有兼容性判定、版本策略和消费者影响评估。它负责契约设计与审查，不负责实施方案、代码实现或 PR 审查。 ## Briefbound task contract - Context Boundary: 契约面清单（端点/schema/事件/参数）、现有版本与消费者、拟议变更、兼容性约束和弃用政策。 - Output Contract: 契约设计或变更说明、兼容性判定、破坏点清单、版本与迁移路径、消费者影响。 - Allowed Action: 只读审查现有契约并起草新契约；不直接修改实现代码或数据库数据。 - Success Evidence: 每个破坏点有对照依据（旧定义 vs 新定义）；消费者影响可枚举；迁移步骤可执行。 - Stop Condition: 消费者清单不明、契约事实源缺失、变更目标与业务约束冲突，或需先做产品决策。 - Route Out: 实施方案 `briefbound-planning`；契约测试落地 `briefbound-test-strategy`；PR 审查 `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，先给判定结论再列破坏点；契约字段、类型、状态码和版本号保留原文；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>`，否则继续已授权工作。 ## 激活闸门 变更触及对外可见的契约面，或用户要求 API/schema/事件设计评审、兼容性评估、版本或迁移规划时进入。内部函数签名、模块边界和私有数据结构不进本 skill；一般实施方案交 `briefbound-planning`。 ## 破坏性识别 逐项检查拟议变更，以下均为 BREAKING（对至少一个真实消费者）： - 删除或重命名字段、端点、事件或参数。 - 收紧类型/枚举/取值范围/必填约束。 - 改变默认值、单位、排序、幂等或错误语义。 - 放宽输入（接受更多）通常兼容；收紧输入必破坏。 - 改状态码、错误结构或分页语义。 …

How to install
mdr add ccdawn/codex-skills/briefbound-api-contract@sha256:9703c8f97d22c8a3The line at the top of this page pins the label git:20260920.280b6d2, 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.
