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 | $0.00043 | $0.01696 |
| Opus 5 | $0.00022 | $0.00848 |
| Sonnet 5 | $0.00009 | $0.00339 |
| Haiku 4.5 | $0.00004 | $0.00170 |
Grade A, and why
briefbound-planning 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 7d 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 实施规划
目标
把已对齐需求整理成最小可实施方案。规划/任务图只防具体风险;可直接验证的任务留给 owner。
Briefbound task contract
- Context Boundary: 已确认意图、相关代码/文档/测试、owning surface、保护边界、已有决策和会改变方案的外部证据。
- Output Contract: 推荐实施路径、影响面、顺序、风险决策、验证策略,以及必要时同一方案内的最小任务图。
- Allowed Action: 只读分析与方案编写;不修改业务代码,不扩大用户范围,不替专项 owner 执行。
- Success Evidence: 方案能映射到具体文件、行为、依赖和验证,且下一执行者无需重新猜测关键取舍。
- Stop Condition: 需求仍有高影响分叉、owning surface 不清、关键证据缺失、高风险动作未确认或方案不能安全实施。
- Route Out: 当前 owner 或专项 owner 直接实施、
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>。
进入闸门
只在规划 artifact 会被审阅、复用、交接或防止具体错误时进入本 skill,例如:
- 存在会改变行为、架构、兼容性或成本的真实设计选择;
- 涉及跨模块契约、状态迁移、数据、权限、安全、发布或回滚顺序;
- 需要多个 owner、多人/agent 或跨会话协作;
- 用户明确要求先看方案。
以下情况不进入:明确机械修改、单一 owning surface、低风险可逆修复、当前 owner 已能直接实施和验证。文件多不等于需要规划。
规划方法
- 继承 Briefbound Router 的可观察结果、非目标、约束和成功证据,不重新发明需求。
- 只读检查会改变方案的文件、接口、状态、测试、日志和项目规则。
- 先考虑项目内复用和平台原生能力;只有外部候选会实质改变架构、依赖或成本时才进入
briefbound-feature-reuse-research。 - 选择最小充分路径,说明影响文件、关键行为/数据流、实施顺序、保护边界和验证方式。
- 只有 Briefbound Router 判为
PROFILE才携带主指标、负载、baseline/测量和停止目标;FAST/CHECK不增加性能章节。 - 只有真实取舍才给 2-3 个方案;否则给一个推荐路径。
- 内部从 1-3 个最相关视角检查需求覆盖、实施可行性、验证和风险。没有 finding 不输出矩阵;发现缺口直接修订方案。
- 根据剩余工作选择
DIRECT_IMPLEMENTATION、COMPACT_PLAN、TASK_GRAPH或BLOCKED;不要再增加一个仅重复拆分判定的流程阶段。
路由判定
默认 DIRECT_IMPLEMENTATION;需要持久方案但无需真实拆分时使用 COMPACT_PLAN。满足以下条件即可由当前 owner 连续实施和验证:
- 一个主题、一个主要 owner,能放入同一推理上下文;
- 顺序可以在内部维护,不需要独立交付或逐项用户验收;
- 风险和验证可以由同一执行契约覆盖。
只有任一条件成立才在当前方案内使用 TASK_GRAPH:
- 存在多个独立交付物或 owner;
- 有真实先后依赖,后续任务必须消费前一任务的 artifact;
- 某个高风险步骤需要独立验收、回滚或权限闸门;
- 需要并行、分 PR、跨会话交接,或不同任务需要不同验证契约;
- 用户明确要求拆分。
多个文件、较长描述、同机制机械替换、需要测试或普通跨模块修改,本身不触发拆分。NO_SPLIT 是 Briefbound Router/Planning 的内部结论,不需要独立 skill 来证明无需拆分。
TASK_GRAPH 模式
任务图与实施方案一次完成:
- 一个任务只对应一个独立交付物、owner、依赖 artifact、风险闸门或验证契约;测试、文档和配置并入所属功能任务。
- 共享写入面、顺序依赖或共享验证保持串行;只有范围和证据真正独立才并行。
- Critical Path 只保留完成目标必需的任务;可选优化进入 Deferred,不生成当前任务卡。
- 每个任务自行选择
SIMPLE或BDD_TDD。只有确定性行为存在重大回归、状态、数据、权限、迁移或公共契约风险时才使用briefbound-bdd-tdd-development。 - 实验 metric lane 路由
briefbound-score-loop;metric 未提升不等于 TDD RED。 - 默认连续执行 Critical Path,已有执行许可时不逐任务询问。
What ships with it
2 files 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.
- 7d ago First seen · 118 lines · 43 tokens per session scan A 887f8dbba4e0
briefbound-planning is a skill published in the GitHub repository CCDawn/codex-skills (4 stars, last pushed 25d ago), licensed MIT. It adds 43 tokens to every session and 1,696 once invoked, about $0.0002 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.
