Shipwright Pipeline

Overview

Shipwright converts a plain-English app description into a fully built, tested, and deployment-ready application. It delegates execution to product-agent, an autonomous 9-phase build engine available on PyPI.

Prerequisites

  • Python 3.10+ available in PATH.
  • product-agent installed (pip install product-agent).
  • Node.js 18+ for JavaScript/TypeScript stacks.

Supported Stacks

  • Next.js + Supabase — Full-stack with auth, database, and edge functions
  • Next.js + Prisma — Full-stack with type-safe ORM
  • SvelteKit — Lightweight full-stack with Svelte
  • Astro — Content-focused static and hybrid sites

Instructions

  • Gather the app description from the user. Ask clarifying questions if the description is vague.
  • Confirm the target stack. If none specified, recommend based on the app type:
  • Data-heavy with auth: Next.js + Supabase
  • API-first with complex models: Next.js + Prisma
  • Lightweight interactive: SvelteKit
  • Content or marketing site: Astro
  • Run product-agent with the app description and selected stack.
  • Monitor the 9-phase pipeline: Intake, Architecture, Scaffold, Implement, Test, Integrate, Polish, Validate, Ship.
  • Report results to the user including test summary and any warnings.

Output

  • A complete, buildable project directory with all source code, tests, and configuration.
  • A test report summarizing pass/fail counts.
  • Build verification output confirming the project compiles and starts.

Error Handling

  • If product-agent is not installed, prompt the user to install it with pip install product-agent.
  • If a phase fails, report the phase name, error message, and suggested fix.
  • If the selected stack is not supported, list available stacks and ask the user to choose.

Examples

Build a SaaS dashboard:

/shipwright-build Build a real-time analytics dashboard with user auth, team workspaces, and Stripe billing. Use Next.js + Supabase.

Add features to an existing project:

/shipwright-enhance Add dark mode toggle, export-to-CSV on all tables, and email notification preferences.

Scaffold a content site:

/shipwright-build Create a developer documentation site with search, versioned docs, and a blog. Use Astro.

How to use it

Copy the folder

Take jeremylongshore/shipwright-pipeline from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference pip. Without those the skill loads but fails at the first command.
