briefbound-planning

briefbound-planning is a skill for Claude Code, Codex from CCDawn/codex-skills. It costs 43 tokens per session (1,696 once invoked), scanned A, original, MIT.

A planning procedure for turning agreed software requirements into a reviewable implementation plan. It maps the goal to affected files, behavior, dependencies, risks, protection boundaries, and verification steps.

In plain words
What is it for?
Use it for multi-owner or higher-risk changes that need a persistent plan, dependency order, risk decisions, and a clear way to prove the result works.
Why use it?
It helps teams make important design and sequencing decisions explicit before implementation, especially when work crosses modules or has migration, permission, release, or rollback concerns.

Token cost

What it costs to keep this loaded

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.

Security

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

  1. 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。
  2. 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。
  3. 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
  4. 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。
  5. 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。
  6. 只有真实取舍才给 2-3 个方案;否则给一个推荐路径。
  7. 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。
  8. 根据剩余工作选择 DIRECT_IMPLEMENTATIONCOMPACT_PLANTASK_GRAPHBLOCKED;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 SIMPLEBDD_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 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.

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.
