feature-breakdown

feature-breakdown is a skill for Claude Code, Codex from ryanzhao1011/workframe. It costs 41 tokens per session (2,035 once invoked), scanned A, original, MIT.

A guide for breaking a large request into an epic, user stories, and smaller tasks. An epic is a broad goal, a user story describes one independently useful outcome, and a task is a concrete piece of work.

In plain words
What is it for?
Use it to split software features, research projects, client deliverables, or content work into executable steps. It supports workflow, role, data, CRUD, and core-path-first breakdowns, with dependency and value checks.
Why use it?
It makes work easier to estimate, assign, test, and complete in order. It also exposes dependencies and keeps development tasks small enough to finish within a short work period.

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

feature-breakdown 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 4d 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.

功能拆解技能

拆解原则

  1. 粒度控制:推荐 0.5–1 天内可完成;研发执行任务优先 ≤4 小时;非研发任务(调研、内容、交付物)按"可独立验收的交付物"拆
  2. 独立可测:每条 Story 满足 INVEST 全部 6 项
  3. 依赖明确depends_on 字段 + 关键路径标注
  4. 价值优先:先拆高价值 Story,再拆技术支撑任务

非软件项目映射:Epic = 目标/交付物;Story = 阶段成果;Task = 行动项。INVEST 和价值矩阵同样适用,Step 3 技术层可跳过。

拆解流程

第 1 步:确认 Epic 边界

从需求文档中提取 Epic 范围:

Epic: EPIC-{序号}
标题:{一句话描述}
范围:{包含哪些功能模块}
排除:{明确不包含的内容}
来源:modules/<basic>/<sub>/requirements/<req_slug>/(需求资产包)

小型需求(Quick Brief 级别)可跳过此步,直接拆 Story。

第 2 步:选择拆分技术

根据需求特征选择最合适的拆分方式:

技术 适用场景 示例
A. 按工作流步骤 有明确的用户操作流程 操作流程:选择配置→输入内容→设定参数→提交→查看结果
B. 按用户角色 多角色使用同一功能 普通用户的操作视图 / 管理员的配置管理 / 超级管理员的全局设置
C. 按数据类型 涉及多种数据实体 内容数据 / 模板数据 / 用户配额数据
D. 按 CRUD 操作 数据实体的标准管理 模板的创建/查看/编辑/删除
E. 主路径优先 需要快速验证核心假设 先实现最小可用的核心流程,再补充配置和管理功能

决策建议

  • 有明确操作流 → 优先选 A
  • 多角色场景 → 优先选 B
  • 标准 CRUD → 优先选 D
  • 不确定 → 默认选 E(降低风险)

第 3 步:按交付链路拆分 Task

每条 Story 进一步拆分为 Task,按依赖方向排列。选择最贴合项目类型的维度:

维度 适用场景 示例
技术层(软件项目) Web/移动端研发 数据层 → API 层 → 业务层 → UI 层 → 集成层
交付物/里程碑 客户交付、研究类 调研报告 → 方案草稿 → 客户确认 → 终稿交付
内容生产流 内容创作 选题确认 → 初稿 → 审校 → 发布 → 数据复盘
角色流转 跨角色协作 PM 需求 → Dev 实现 → QA 验收
风险假设 有核心不确定性 先验证最高风险假设,再补全路径

第 4 步:工时估算

复杂度 预估工时 典型任务
简单 1-2 小时 简单 CRUD、UI 微调、配置变更
中等 2-3 小时 业务逻辑、数据校验、组件开发
复杂 3-4 小时 复杂交互、外部集成、性能优化
超标 >4 小时 必须继续拆分

第 5 步:价值 vs 工作量矩阵

对拆解后的 Story 进行 2×2 矩阵评估:

                低工作量          高工作量
高价值    │  ★ 优先做        │  计划做(安排迭代)  │
低价值    │  顺手做(填充空闲)│  不做(除非必须)    │

评估维度:

  • 价值:用户影响力 + 战略对齐度 + 业务紧迫性
  • 工作量:开发工时 + 技术风险 + 依赖复杂度

第 6 步:INVEST 验证

对每条 Story 逐项检查:

原则 检查问题 通过?
I ndependent(独立) 不依赖未承诺的其他 Story?
N egotiable(可谈判) 有多种实现方案可选?
V aluable(有价值) 对用户或业务有明确价值?
E stimable(可估算) 团队理解范围,能给出工时?
S mall(足够小) 可在一个迭代内完成?
T estable(可测试) 有可写出验收方向?(详细 AC 由 acceptance-criteria 细化)

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.

feature-breakdown is a skill published in the GitHub repository ryanzhao1011/workframe (4 stars, last pushed 18d ago), licensed MIT. It adds 41 tokens to every session and 2,035 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.
