briefbound-performance-engineering skillA
briefbound-performance-engineering is agent-read markdown (skill) from ccdawn/codex-skills: Use when an explicit performance goal, measurable regression, unresolved hot path, large workload, concurrency/cache/streaming decision, or latency/throughput/CPU/memory/I/O/bundle budget needs profiling and evidence-backed optimization; do not use for routine development, speculative cleanup, or an already-located N+1/local inefficiency whose batch fix and deterministic count verification are clear to the current owner..
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 性能工程 ## 目标 用最小测量找到真正限制结果的瓶颈，只保留收益超过噪声与复杂度成本的优化。普通开发不经过本 skill。 ## Briefbound task contract - Context Boundary: 已确认的性能目标或强信号、代表性负载、owning surface、现有指标/benchmark/profile、正确性契约和允许写入范围。 - Output Contract: baseline、主要瓶颈、最小优化、同负载对比、取舍、正确性验证和必要的回归保护。 - Allowed Action: 读取相关代码和运行证据，执行有界 benchmark/profile，修改已授权 scope 并运行相关验证；不自动安装全局工具、不压测生产、不扩大产品行为。 - Success Evidence: 相同负载下有可比较的 before/after，收益超过测量噪声或目标已满足，且正确性验证通过。 - Stop Condition: 没有性能强信号、无法建立安全负载、瓶颈不在可改范围、需要高风险架构取舍、收益不足以抵偿复杂度，或目标已经满足。 - Route Out: 当前开发 owner、`briefbound-bug-review`、`briefbound-pr-review`、`briefbound-development-cleanup`、`briefbound-router` 或 BLOCKED。 ## 统一调用契约 - 只处理 Briefbound task contract 范围；不匹配时回最具体 owner。用户可见内容默认中文，保留指标、命令、路径、API 和工具名。 - 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。 - 不把性能工程变成固定开发阶段，也不要求用户逐步确认已授权的测量、优化和验证。 ## 三档边界 Briefbound Router 使用 `FAST / CHECK / PROFILE`： - `FAST`：低频、低规模、机械修改，直接开发和验证，不输出性能检查。 - `CHECK`：当前 owner 静默处理已定位的 N+1、循环 I/O、重复全量计算、隐藏高阶复杂度和无界增长；批量修复及查询/调用次数断言仍是确定性验证，不加载本 skill、不建 benchmark，也不因“发现问题”切到 bug owner。只有存在已观察到的故障、正确性回归或待诊断根因时才路由 `briefbound-bug-review`。 …

How to install
mdr add ccdawn/codex-skills/briefbound-performance-engineering@git:20260916.292b0acmdr add ccdawn/codex-skills/briefbound-performance-engineering@sha256:4de3facc6e12255dPin 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.
