wwas

wwas is a skill for Claude Code from killvxk/pm-skills-zh. It costs 70 tokens per session (837 once invoked), scanned A, original, MIT.

A format for writing product work items with three parts: why the work matters, what will be built, and how to tell it is complete. WWA means Why, What, and Acceptance criteria.

In plain words
What is it for?
Use it to break a feature into independent backlog items, describe design references, and define high-level acceptance criteria for a sprint.
Why use it?
It connects a task to its purpose while keeping the expected result testable. This helps teams discuss implementation details without losing sight of user or business value.

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

wwas 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.

What it actually says

为什么-做什么-验收标准(WWA)

以「为什么-做什么-验收标准」(Why-What-Acceptance,简称 WWA)格式创建产品待办事项。生成独立、有价值、可测试的工作项,包含战略背景。

适用场景: 编写待办事项、创建产品增量、将功能拆解为工作项,或向团队传达战略意图时。

参数:

  • $PRODUCT:产品或系统名称
  • $FEATURE:新功能或能力
  • $DESIGN:设计文件链接(Figma、Miro 等)
  • $ASSUMPTIONS:关键假设和战略背景

Step-by-Step Process(分步流程)

  1. 定义战略「为什么」 - 将工作与业务和团队目标挂钩
  2. 描述「做什么」 - 保持描述简洁,引用设计文件
  3. 编写验收标准 - 高层次的标准,而非详细规格
  4. 确保独立性 - 工作项可以任意顺序开发
  5. 保持可协商性 - 邀请团队讨论,而非施加约束
  6. 确保有价值 - 每个工作项交付可量化的用户或业务价值
  7. 确保可测试性 - 成果可被观察和验证
  8. 适当分配规模 - 小到足以在一个 Sprint 内估算完成

Item Template(工作项模板)

标题: [将交付的内容]

为什么: [1-2 句话,与战略背景和团队目标挂钩]

做什么: [简短描述和设计链接。最多 1-2 段。是讨论的备忘,而非详细规格。]

验收标准:

  • [可观察结果 1]
  • [可观察结果 2]
  • [可观察结果 3]
  • [可观察结果 4]

Example WWA Item(WWA 工作项示例)

标题: 实现实时消费追踪器

为什么: 用户需要对消费有即时反馈,才能做出有意识的预算决策。这直接支撑我们提升财务意识、减少超支的目标。

做什么: 添加一个实时消费追踪器,在用户记录支出时实时更新。追踪器显示用户当周消费金额与设定预算的对比情况。设计详见 [Figma 链接]。这是我们讨论的备忘——详细规格将在与团队的开发对话中逐步明确。

验收标准:

  • 记录支出后 2 秒内消费总额更新
  • 用进度条直观呈现预算使用进度
  • 用户可以一目了然地看到剩余预算金额
  • 系统正确处理多个支出类别

Output Deliverables(输出交付物)

  • 该功能的完整待办事项集
  • 每个工作项包含「为什么」、「做什么」和「验收标准」三个部分
  • 工作项相互独立,可任意顺序交付
  • 工作项规模适合在一个 Sprint 内估算和完成
  • 团队决策所需的战略背景清晰
  • 包含设计参考,为实现提供指引

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.
