SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Excel方眼紙の設計書を毎回手作業で整える負担をなくし、JSON定義から機能追加の設計書を一貫した形式で素早く生成できるようにします。

Core Features & Use Cases

テンプレート駆動生成: 既定のExcelテンプレートを基に、表紙から運用フローまでの構成を自動反映します。
設計情報の構造化: 概要、要件、データモデル、画面設計、API、ルール、開発計画をJSONで整理して出力できます。
図表の組み込み: ER図、遷移図、画面モックアップなどのSVG図を設計書に紐づけて扱えます。
Use Case: 新機能の仕様がまとまったらJSONを作成し、このスキルでそのまま配布可能なExcel設計書に変換します。

Quick Start

JSON定義を用意して、このスキルにExcel設計書の生成を依頼してください。

FAQPage Schema

How do I generate Excel design documents from JSON definitions?▼

To generate Excel design documents from JSON, provide structured JSON inputs containing feature specifications, data models, and APIs to reconstruct a template-aware workbook with deterministic output.

Can I include ER diagrams and screen mockups when generating Excel specs from JSON?▼

Yes, you can include ER diagrams and screen mockups when generating Excel specs by providing optional SVG diagrams in your JSON definitions for direct embedding into the functional design document.

What sections are covered when converting JSON to functional design documents?▼

Converting JSON to functional design documents covers feature specifications, data models, screen designs, APIs, business rules, development plans, and operation flows from a reusable Excel template.

Does this spec generation process require ClosedXML and dotnet-script?▼

Yes, this spec generation process relies on ClosedXML and dotnet-script to apply template-aware sheet reconstruction and produce deterministic Excel workbook outputs from JSON.

What is the best way to standardize feature specifications into Excel without manual formatting?▼

Standardizing feature specifications into Excel without manual formatting is best achieved by structuring design information into JSON and applying a template-driven generation process for consistent workbook output.

Are there limitations to reconstructing Excel sheets from JSON templates?▼

A limitation of reconstructing Excel sheets from JSON templates is that inputs must be strictly structured JSON definitions, and diagram handling is limited to optional SVG formats for deterministic output.
