    Example session with this skill installed

    I have an idea for a peer-to-peer equipment rental app for photographers. Let's spec this out.

    • Read your context and instructions
    • Compiled the spec blueprint

    I will guide you through the brainstorming phase to define the peer-to-peer rental app. We will start by pinning down the core user experience before moving to the technical architecture.

    Question 1: Who is the primary user for the launch version: professional studios looking to offset costs, or hobbyists looking for specific lenses for a weekend?

    Proposed Architecture Preview

    • Frontend: Next.js with Tailwind CSS for the marketplace UI.
    • Backend: Node.js API with PostgreSQL for complex availability queries.
    • Auth: Clerk or Auth0 for identity and verification.
    • Storage: Stripe Connect for split-payments and escrow.

    Next steps

    1. Answer the user persona question above to define our first requirement.
    2. We will then discuss the "Equipment Verification" flow to prevent fraud.
    3. Once the interview is complete, I will generate the system_spec.md file.

    About this skill

    Stop guessing at requirements and building generic software. This skill replaces vague project ideas with a rigorous, developer-ready implementation roadmap. It forces clarity through a phased discovery process, ensuring every technical decision is rooted in a specific user need before a single line of code is written.

    What it does

    • Interactive Discovery — Conducts a one-question-at-a-time interview to extract non-obvious requirements and constraints.
    • Spec Compilation — Generates a comprehensive technical specification covering architecture, data handling, and error strategies.
    • Architectural Blueprinting — Produces PRDs, TRDs, Mermaid ER diagrams, and detailed user flows for the entire system.
    • Right-Sized Planning — Breaks implementation into a three-pass plan to ensure tasks are neither too broad to review nor too small to be meaningful.
    • Prompt Engineering — Delivers a sequenced series of standalone code-generation prompts for every step of the build.

    How it works

    1. The Interview — Use /spec or describe a new idea to start the interactive brainstorming phase.
    2. The Blueprint — Review the generated technical docs, schema designs, and implementation timeline.
    3. The Execution — Copy the sequenced code-generation prompts into your development environment to build the project step-by-step.

    Frameworks & tools

    This skill is platform-agnostic but excels at designing full-stack applications, REST/GraphQL APIs, and database-driven systems. It uses Mermaid for ER diagrams and standard Markdown for all technical documentation.

    Why this beats prompting it yourself

    Standard prompts often produce generic "To-Do List" style plans that ignore edge cases and scaling constraints. This skill uses a multi-pass refinement logic that forces you to define data relationships and error states before generating code prompts, preventing expensive mid-build refactors.

    Use cases

    • Drafting a full-stack application architecture from a rough business concept.
    • Designing a complex new feature for an existing system without bloating the codebase.
    • Generating a sequenced build-log for junior developers or offshore teams to follow.
    • Creating a stakeholder-ready project timeline and technical roadmap for a greenfield project.

    Known limitations

    This skill is not for bug fixes or minor modifications to existing code. It requires an active discovery phase and is not intended for users who want an instant one-shot scaffold.
