Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00060 | $0.01961 |
| Opus 5 | $0.00030 | $0.00981 |
| Sonnet 5 | $0.00012 | $0.00392 |
| Haiku 4.5 | $0.00006 | $0.00196 |
Grade A, and why
briefbound-feature-reuse-research scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Briefbound Feature Reuse Research
目标
在复杂功能进入方案制定前,先做只读复用研究:搜索相关项目、库、模块、官方示例和成熟实现,评估是否值得复用、改造、只参考,或自研。
本 skill 不写代码、不安装依赖、不把外部代码直接复制进项目。它输出一个可交给 briefbound-planning 的复用决策。
Briefbound task contract
- Context Boundary: 用户目标、当前项目可复用点、网络/本地搜索范围、排除范围、许可证和依赖边界。
- Output Contract: 搜索范围、候选评估、复用决策、Implementation Boundary、Verification Strategy 和 planning handoff。
- Allowed Action: 只读搜索和只读本地代码/文档检查;不安装依赖、不运行外部代码、不复制外部代码、不扩大用户未确认范围。
- Success Evidence: 当前项目复用点已查,候选有链接或本地证据,许可证/集成风险已判断,复用决策能作为
briefbound-planning输入。 - Stop Condition: 无法搜索、许可证不明、需求不清、复用会改变用户未确认范围、需要安装/试跑/复制外部代码。
- Route Out: 原开发 owner、
briefbound-planning、继续复用研究、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,完成只报状态、产出、证据和剩余风险;代码、命令、路径、错误原文、API/协议、skill 名和枚举保留原样;Route Out 仅以 Briefbound task contract 为准,末行写
下一步建议: <一个具体动作>。
进入条件
使用前确认:
- 用户目标是新增功能、模块、能力、工作流、复杂 UI、集成、解析器、编辑器、搜索、可视化、导入导出、算法或可复用子系统;
- 功能复杂度足以影响方案选择,且外部生态可能已有成熟实现;
- 搜索结果会改变实现路径、依赖选择、风险、成本或验证方式;
- 允许联网搜索。若当前不能联网,说明限制,并用本地已有依赖、文档和代码做降级研究。
至少需要一个强信号:成熟领域引擎/协议/标准、重要新依赖、跨模块子系统、项目内无稳定模式、用户明确要求外部复用,或 QUICK 搜索可显著避免高成本自研。文件数量和“网上可能有项目”不算强信号。
不使用本 skill:
- 单点小改、样式调整、普通 bug 修复、机械重构;
- 用户明确要求从零实现;
- 功能高度私有,外部实现没有可比价值;
- 复用只会增加依赖、许可证、维护或集成负担。
研究范围
按功能类型选择 2-4 类来源,不要盲目铺开:
- 官方文档和官方示例:框架、SDK、协议、浏览器/API、平台能力。
- 包管理器生态:npm、PyPI、Cargo、Go modules、Maven、NuGet 等。
- GitHub 项目:相似产品、组件库、插件、参考实现、算法实现。
- 当前项目内复用:已有模块、工具函数、设计系统、服务接口、测试 helper。
- 标准/论文/规范:协议、格式、算法、互操作行为。
优先级:
- 当前项目已有可复用模块;
- 官方推荐库或官方示例;
- 活跃、许可证清晰、测试充分的成熟库;
- 可参考的开源项目设计;
- 自研。
默认先 QUICK:检查项目内复用点,再查看 2-4 个最相关的官方来源、成熟库或 GitHub 项目;决策已稳定就停止,不为凑候选扩大搜索。只有许可证、架构适配或关键能力仍无法判断时才进入 DEEP。
候选筛选
每个候选必须有明确价值,不凑数。最多保留 3-5 个候选。
候选字段:
- Name / Link:名称和来源链接;
- Capability Fit:覆盖目标功能的哪些部分;
- License:许可证是否允许当前项目使用;
- Activity:维护活跃度、近期提交、issue 状态、发布频率;
- Integration Cost:接入成本、依赖体积、框架/语言/运行时兼容;
- Adaptation Cost:需要改造的程度;
- Testability:是否容易写测试和验证;
- Project Fit:是否符合当前架构、代码风格、依赖边界和长期维护能力;
- Risk:供应链、弃维护、过度依赖、API 不稳定、性能或可扩展性风险。
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 10d ago First seen · 146 lines · 60 tokens per session scan A 397569667ea8
briefbound-feature-reuse-research is a skill published in the GitHub repository CCDawn/codex-skills (6 stars, last pushed 28d ago), licensed MIT. It adds 60 tokens to every session and 1,961 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
