Product builder workflow: research, PRD, tech stack, architecture, UI specs
Use when user wants deep competitor feature analysis. Triggers: "analyze competitor features", "teardown competitors", "what features do competitors have", "competitor deep dive". Requires knowing which competitors to analyze—if unclear, suggest market-research first.
Use when user explicitly wants market research, competitor analysis, or needs help deciding what product to build. Triggers: "do market research", "analyze competitors", "what should I build", "validate this idea", "is there a market for". Do NOT trigger for casual product discussions or when user already has clear requirements.
Use when user explicitly wants to write or create a PRD/product requirements document. Triggers: "write PRD", "create PRD", "document requirements", "define the product". Requires user to have a product direction—if unclear, suggest market-research first.
Use for top-level system architecture after stack decision. Triggers: "system architecture", "module design", "technical architecture". Requires stack.md to exist.

npx claudepluginhub sparktech-ai/skills --plugin product-builderプロダクトの基盤情報(課題仮説・ソリューション・市場スコープ・原体験・ビジネスモデル・競合・差別化)を ユーザーとの対話で掘り下げ、構造化されたドキュメント(product-context.md)として整理するスキル。 「自分のプロダクトって結局何なの?」を一緒に整理する壁打ち相手として機能する。 ペルソナ作成、LP設計、機能優先順位、マーケティング戦略など、 プロダクトの方向性に関わるあらゆる意思決定の「前提情報」を1ファイルにまとめる。 コードベースがあれば自動で読み取れる部分は埋め、残りをユーザーにヒアリングする。 Use when: 「プロダクトを整理したい」「ターゲット整理」「コンテキスト作成」 「ペルソナの前に」「誰向けのプロダクトか整理」「プロダクト情報まとめ」 「product context」「プロダクト定義」「プロダクトの前提」 「product discovery」「誰向け」と言われた時。 新しいプロジェクトの立ち上げ時や、方向性を見直したい時にも使う。 ペルソナ作成スキルを使う前に、まずこのスキルでプロダクトの前提を整理すべき。 Triggers: "product discovery", "product context", "プロダクト整理", "ターゲット整理", "コンテキスト作成", "プロダクト定義", "プロダクトの前提", "ペルソナの前に", "誰向け", "プロダクト情報まとめ", "プロダクトって何", "何を作ってるか整理", "どんな需要があるか"
Guides you through creating a Product Requirements Document (PRD) for a new app or feature.
