dev-plan

dev-plan is a skill for Claude Code from Stanshy/AgentHub. It costs 16 tokens per session (1,371 once invoked), scanned A, original, MIT.

A development-plan generator for a numbered sprint, a fixed period of planned development work, and its project.

In plain words
What is it for?
It is for creating sprint plans, API and data-model specifications, feature requirements, a sprint branch, and tracking tables.
Why use it?
It turns an existing proposal into a structured plan and records the technical rules needed for later code review.

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

dev-plan 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 1mo 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.

開發計畫書產生器

G0 通過後,由 L1 產出標準化開發計畫書。

使用方式

/dev-plan <sprint-number> <project-name>

參數

  • $0: Sprint 編號
  • $1: 專案名稱

執行步驟

  1. 讀取對應的提案書: !cat proposal/sprint$0-proposal.md 2>/dev/null || echo "找不到 Sprint $0 提案書"

  2. 讀取開發計畫書範本: !cat .knowledge/templates/dev-plan.md.template 2>/dev/null || echo "範本未找到"

  3. 建立規範文件(若不存在則建立,已存在則跳過):

    ⚠️ 規範文件是 Code Review「對規範」的比對對象,缺少 = Review 品質打折。 必須在 dev-plan 產出時一併建立,不得延後。

    mkdir -p .knowledge/specs
    

    建立以下三個檔案(內容從提案書 + 技術方案提取):

    檔案 內容 來源
    .knowledge/specs/api-design.md API 端點清單、請求/回應格式、錯誤碼 提案書需求 + 技術方案
    .knowledge/specs/data-model.md 資料表定義、欄位型別、關聯、索引 技術方案 DB 設計
    .knowledge/specs/feature-spec.md 功能規格、用戶流程、邊界條件、驗收標準 提案書功能清單

    每個檔案格式:

    # {標題}
    
    > 版本: v1.0 | Sprint {N} | 最後更新: {YYYY-MM-DD}
    
    ## 概述
    {簡述}
    
    ## 詳細規格
    {具體內容}
    
  4. 建立 Sprint Branch:

    BASE=$(git rev-parse --abbrev-ref HEAD)   # 記錄當前 base branch(main / master / 其他)
    git checkout -b sprint-$0
    

    若 sprint-$0 branch 已存在,輸出警告並跳過(冪等)。 $BASE 將寫入 dev-plan metadata,供 /sprint-close 使用。

  5. 產出 proposal/sprint$0-dev-plan.md,包含:

    • 需求摘要(來自提案書)
    • 技術方案
    • 檔案變更清單
    • 介面設計(如需要)
    • 第 5 節:規範文件索引(指向 .knowledge/specs/ 下的三個檔案)
    • 第 6 節:任務拆解表(含依賴圖)
    • 驗收標準
    • 異常處理
    • 時程預估
    • 第 10 節:預建空表格(任務完成紀錄 / Review 紀錄 / Gate 紀錄)

第 10 節格式(強制)

⚠️ 此區域的表頭名稱與欄位順序被系統 parser (parseDevPlanSection10) 嚴格依賴。 不得更改表頭名稱、欄位順序、或子標題名稱。

## 10. 任務與審核紀錄(備查)

> 每個任務完成後記錄結果,每次 Review/Gate 通過後記錄決策。本區作為 Sprint 完整稽核軌跡。

### 任務完成紀錄

| 任務 | 完成日期 | 結果 | 備註 |
|------|---------|------|------|
| T1 | | | |
| T2 | | | |
(依第 6 節任務清單預建所有任務行)

### Review 紀錄

| Review 步驟 | 日期 | 結果 | Review 文件連結 |
|------------|------|------|---------------|
| UI 圖稿 Review | | | |
| 實作 Review | | | |
| 測試 Review | | | |
(依確認流程中的步驟預建行)

### Gate 紀錄

| Gate | 日期 | 決策 | 審核意見 |
|------|------|------|---------|
| G0 | | | |
| G1 | | | |
(依確認流程中的 Gate 預建行,空行 = 未審核)

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.
