About this skill
機能設計書作成スキル
このスキルは、高品質な機能設計書を作成するための詳細ガイドです。
前提条件
機能設計書作成を開始する前に、以下を確認してください:
docs/product-requirements.md が作成されている
必須: PRDが以下の場所に存在する必要があります:
ファイルパス: docs/product-requirements.md
機能設計書は、PRDで定義された要件を技術的に実現する方法を詳細化します。
既存ドキュメントの優先順位
重要: docs/functional-design.md に既存の機能設計書がある場合、
以下の優先順位に従ってください:
-
既存の機能設計書 (
docs/functional-design.md) - 最優先- プロジェクト固有の設計が記載されている
- このスキルのガイドより優先する
-
このスキルのガイド - 参考資料
- 汎用的なテンプレートと例
- 既存設計書がない場合、または補足として使用
新規作成時: このスキルのテンプレートとガイドを参照 更新時: 既存設計書の構造と内容を維持しながら更新
出力先
作成した機能設計書は以下に保存してください:
docs/functional-design.md
テンプレートの参照
機能設計書を作成する際は、次のテンプレートを使用してください: ./template.md
詳細ガイド
さらに詳しい作成ガイドは次のファイルを参照してください: ./guide.md
When not to use it
- →When the task is not related to creating or updating functional design documents
Prerequisites
Limitations
- →Only for creating functional design documents
- →Requires an existing product requirements document
How it compares
This skill provides a structured approach with templates and guides, ensuring consistency and alignment with product requirements, unlike a manual process.

mermaid-diagrams
davila7
Comprehensive guide for creating software diagrams using Mermaid syntax. Use when users need to create, visualize, or document software through diagrams including class diagrams (domain modeling, object-oriented design), sequence diagrams (application flows, API interactions, code execution), flowcharts (processes, algorithms, user journeys), entity relationship diagrams (database schemas), C4 architecture diagrams (system context, containers, components), state diagrams, git graphs, pie charts, gantt charts, or any other diagram type. Triggers include requests to "diagram", "visualize", "model", "map out", "show the flow", or when explaining system architecture, database design, code structure, or user/application flows.
create-cli
steipete
Design command-line interface parameters and UX: arguments, flags, subcommands, help text, output formats, error messages, exit codes, prompts, config/env precedence, and safe/dry-run behavior. Use when you’re designing a CLI spec (before implementation) or refactoring an existing CLI’s surface area for consistency, composability, and discoverability.
design-review
