Forge

Forge Skill

Turn any business description into a production-grade data platform and complete product scaffold: schema, migrations, repository code, APIs, tests, UI surfaces, Docker Compose, and infra-ready artifacts.

Core Principles

1. Respect the user's explicit stack. If the prompt specifies language, framework, ORM, cloud,

database version, UI stack, or deployment target, use that stack. Do not silently default to TypeScript or any other stack when the user asked for something else.

1. Build all implied product surfaces, not just a dashboard. If the product needs customer,

operator, admin, onboarding, auth, marketing, checkout, or support flows, implement them. Never stop at one dashboard unless the user explicitly asked for only that view.

1. Never hardcode UI data. All UI data must come from real queries, real APIs, or typed fixtures

explicitly created for dev/test paths.

1. Use real ORMs and live database connections. Repository code must use the stack-appropriate ORM

and real connection configuration. Prefer Datafy MCP tools for schema and DB operations.

1. Every schema change must be migration-driven. Never mutate a live schema with ad hoc raw DDL

after initial provisioning.

1. Use strong project structure. Organize code by domain, layer, or app boundary appropriate to the

chosen stack. No flat dumps.

1. Proactively orchestrate sibling skills. You must use api-test-generator,

frontend-data-consumer, frontend-design-review, cloud-solution-architect, and infrastructure-as-code-architect when their phase applies.

1. Tailwind and Shadcn are implementation tools, not the design itself. The UI must have a clear

product-appropriate visual direction, sound hierarchy, accessibility, and interaction quality.

1. Default infra choices only when the user did not specify them:

• Terraform provider: gcp
• Docker Compose Postgres image: postgres:18-alpine
• Include Docker Compose in the infra repo as well as app-local setup when useful

Clarification Rules

Before building, resolve or infer:

• preferred stack
• product surfaces and user roles
• auth model
• deployment target
• cloud provider
• monorepo vs single app

If the user already specified any of these, do not re-ask them unless there is a real conflict. When the prompt is specific, proceed with that stack.

Workflow

Step 0 — Architecture and Repo Strategy

Use cloud-solution-architect first.

1. Use github-mcp-server to discover whether code should go into an existing repo or a new app

plus infra repo layout.

1. Choose architecture style that matches the product and scale.
2. Default Terraform provider to GCP unless the user specified AWS, Azure, or another target.
3. Ensure there is an infra home for deployment assets. Put Docker Compose alongside app setup when

helpful, and also include it in the infra repo or infra package for operational reuse.

Step 1 — Honor the Requested Stack

If the user says Laravel, Go, .NET, FastAPI, Next.js, Nuxt, Django, Rails, Kotlin, etc., use it. Do not translate the request into a TypeScript stack unless the user asked for TypeScript or left the stack unspecified.

Use context7-mcp for the chosen frameworks and libraries so the generated setup follows current official patterns.

Step 2 — Model the Business

Extract:

• actors
• roles
• workflows
• transactions
• entities
• state transitions
• operational views

Explicitly enumerate the UI surfaces implied by the product. Example: a meal-kit service may require customer storefront, subscription management, checkout, admin catalog, kitchen operations, delivery coordination, and analytics.

Step 3 — Design the Data Layer

Generate PostgreSQL schema in 3NF unless the stack demands otherwise. Use:

• UUID primary keys where appropriate
• explicit foreign key policies
• timestamp columns
• proper indexes
• money-safe decimal types

Present schema for approval before execution when the user is in a planning mode; otherwise proceed.

Step 4 — Prisma 7 + PostgreSQL Playbook

When using Prisma 7 with PostgreSQL, follow this pattern.

1. Centralize env loading in one shared side-effect module that resolves the workspace-root .env

by absolute path.

1. Reuse that env loader everywhere:

• app runtime
• prisma.config.ts
• seed scripts
• background workers

1. Centralize Prisma client options in one helper.
2. For Prisma 7 + PostgreSQL, default to:

• @prisma/adapter-pg
• pg
• new PrismaPg({ connectionString: env.DATABASE_URL })
• new PrismaClient({ adapter })

1. For money-like PostgreSQL columns, emit:

amount Decimal @db.Decimal(10, 2)

Do not emit @db.Numeric(...) for this Prisma 7 setup.

1. Make prisma.config.ts cwd-independent by importing the shared env loader.
2. Reuse the same env/runtime path in prisma/seed.ts; do not duplicate dotenv path math.
3. In monorepos, assume .env lives at the workspace root unless the repo clearly establishes a

different convention.

1. Verify these commands from the package directory, not only repo root:

• pnpm install
• pnpm db:generate
• pnpm db:migrate
• pnpm db:seed

Recommended layout:

apps/api/
  prisma.config.ts
  prisma/
    schema.prisma
    seed.ts
  src/
    config/
      load-env.ts
      env.ts
    db/
      prisma-options.ts
      prisma.ts

Required dependencies for Prisma 7 + PostgreSQL:

{
  "@prisma/adapter-pg": "^7.x",
  "@prisma/client": "^7.x",
  "pg": "^8.x",
  "prisma": "^7.x"
}

Step 5 — Provision Environment and Infra

Use infrastructure-as-code-architect.

1. Generate production-ready Dockerfiles.
2. Generate Docker Compose for local development.
3. Default the Postgres service image to postgres:18-alpine unless the user asked for another

version.

1. Put Docker Compose in the infra repo or infra package, not only the app directory.
2. Generate Terraform with GCP as the default provider unless the user specified another provider.
3. Generate CI/CD and deployment assets.

SHIPPABILITY CONTRACT — MANDATORY for any web app destined for ship-to-vps:

The repo this step emits must satisfy every item in ~/.claude/skills/ship-to-vps/references/shippability-contract.md. Each item maps to a real production failure that has happened. Do not skip any:

• Dockerfile at repo root, multi-stage, with LABEL org.opencontainers.image.source=... on the

final stage (auto-links GHCR package to the repo so ephemeral GITHUB_TOKEN can pull during deploy)

• Runner stage must include the FULL node_modules tree if Prisma 7 migrations run from the

same image — @prisma/config requires effect and other transitive deps that the standalone bundle omits. Splitting into a separate migrator stage is acceptable; copying only node_modules/prisma is not.

• Invoke migrations via node ./node_modules//build/index.js, not npx — standalone

runners don't ship node_modules/.bin/ shims

• .eslintrc.json (or framework equivalent) MUST exist — running next lint without one

triggers an interactive prompt that hangs CI

• .dockerignore that does NOT exclude prisma/, public/, or any config file the Dockerfile

COPYs

• Tracked .gitkeep in every directory the Dockerfile COPYs that may otherwise be empty

(e.g. public/.gitkeep for Next.js without static assets) — git does not track empty dirs, so CI checkout will miss them even though local FS makes the build appear to work

• .infisical.json at repo root with valid workspaceId, created at Step 0 of this workflow
• AGENTS.md — use ~/.claude/skills/ship-to-vps/templates/docs/AGENTS.md as the template,

parameterized with this project's slug, domain, stack

• No committed .env* files — verify gitignore covers them
• App reads DATABASE_URL from env and listens on a single TCP port (default 3000)

Before declaring Step 5 complete, walk the checklist at the bottom of ~/.claude/skills/ship-to-vps/references/shippability-contract.md and confirm every box.

Step 6 — Provision Database via Datafy

Use available execute_admin_sql_ and execute_sql_ tools.

1. Verify or create the target database.
2. Apply schema in dependency order.
3. Keep execution safe and repeatable.
4. If dbhub.toml changes are required, update it and clearly tell the user that MCP must be

restarted.

Step 7 — Repository Code and Services

Generate stack-appropriate repository code, services, routes, handlers, and DTO/contracts. Keep code idiomatic for the requested stack.

Step 8 — Frontend Generation Standards

Use both frontend-data-consumer and frontend-design-review.

Rules:

1. Build modern, near-best-in-class UI quality for the product category.
2. Choose one or two successful reference products in the same category and mimic their

interaction model, density, layout rhythm, navigation style, and information hierarchy without copying branding.

1. Consult current design guidance before locking the UI direction. Good anchors include Apple HIG,

Material 3, and mature product design systems. Prefer hierarchy, clarity, spacing, and sensible motion over novelty for its own sake.

1. Do not ship generic “Tailwind + shadcn demo dashboard” output.
2. Tailwind/shadcn may be used for implementation, but the UI must still feel intentional and

product-specific.

1. Build all required UI surfaces, not just the dashboard.
2. Ensure accessibility basics: readable typography, keyboard support, contrast, state cues beyond

color, and adequate target sizes.

Step 9 — Tests and Verification

Use api-test-generator and verify the generated repo actually works.

At minimum validate:

• install
• schema generation
• migrations
• seeding
• app boot
• tests

If Prisma is involved, explicitly validate the Prisma commands from the package directory.

Internal Orchestrator Prompt Rules

When acting as the orchestrator:

1. Use the forge skill immediately.
2. Respect the exact stack named in the user's goal.
3. Implement all major UI surfaces implied by the business, not only a dashboard.
4. Use current official docs and patterns for the selected stack.
5. Default Terraform to GCP if the user did not specify a cloud.
6. Default Docker Compose Postgres to postgres:18-alpine if the user did not specify a version.
7. Put Docker Compose into the infra repo/package as part of the deliverables.
8. If using Prisma 7 + PostgreSQL, follow the Prisma playbook above exactly.

Hard rules:

• Never hardcode business data in the UI.
• Never ignore an explicitly requested stack.
• Never emit only one UI view when the business clearly needs several.
• Never rely on cwd-sensitive env loading for Prisma monorepos.
• Never default to @db.Numeric(...) for Prisma 7 PostgreSQL money fields in this setup.
• Never emit a web-app scaffold that violates the shippability contract — the next skill in the

chain (ship-to-vps) depends on every item. See Step 5 for the enumerated requirements and ~/.claude/skills/ship-to-vps/references/shippability-contract.md for full rationale.

• Never copy only node_modules/prisma + @prisma/* into a runner image when migrations are

expected to run from that image. Prisma 7's @prisma/config requires effect. Copy the full node_modules tree or build a dedicated migrator stage.

• Never let CI invoke next lint without .eslintrc.json present — it prompts interactively and

hangs the runner.

Handoff to ship-to-vps

After Step 9 verification, if the user wants the app deployed to their VPS, hand off to the ship-to-vps skill. It expects exactly the contract this skill emits and will scaffold:

• .github/workflows/{ci,deploy,infisical-sync}.yml
• /opt// on the VPS (docker-compose, .env projected from Infisical, Caddy site config)
• Cloudflare DNS A-record (if user opted into Cloudflare integration)
• GHCR bootstrap (push current image with :bootstrap tag for rollback)
• First end-to-end deploy

If the user says "ship it" / "deploy this" / "wire up CI/CD" / "set up auto-deploy", trigger ship-to-vps.
