Intermediate — New Project Creation with Claude

Prompt patterns for designing and building greenfield services

Apply prompt engineering to the first phases of a new project: domain discovery, architecture decisions, API design, data modelling, and an initial test layer. The intermediate companion to the Advanced new-project program.

Module 1 — Requirements & Architecture

Domain discovery, ADRs, and NFR specifications with Claude — at an intermediate depth.

Start
  1. 1
    Domain discovery with Claude
    Lightweight Event Storming and bounded-context identification with one-shot prompts.
  2. 2
    Architecture Decision Records
    Drafting MADR-format ADRs from a short context brief.
  3. 3
    Non-functional requirements
    Measurable NFR specifications across performance, availability, security, observability.

Module 2 — Domain Model Implementation

Aggregates, value objects, and CQRS basics with Claude prompts.

Start
  1. 1
    Rich domain entities
    Prompting for entities with private setters, invariant enforcement, and factory methods.
  2. 2
    Value objects
    Immutable, equality-by-value types with constructor validation.
  3. 3
    CQRS basics
    Generating a command, validator, and handler for a single feature.

Module 3 — API Design

Contract-first APIs, error handling, and authentication prompts.

Start
  1. 1
    OpenAPI contract first
    Generating an OpenAPI 3.1 contract from a feature description.
  2. 2
    Error handling
    RFC 7807 Problem Details across the API surface.
  3. 3
    Authentication basics
    JWT-based auth setup; refresh tokens; basic RBAC.

Module 4 — Data & Testing

Database schema generation and the first test layer.

Start
  1. 1
    Schema generation
    PostgreSQL schema with indexes, audit fields, soft delete patterns.
  2. 2
    Unit test generation
    Prompts that produce xUnit/NUnit tests for domain logic.
  3. 3
    Integration tests
    WebApplicationFactory-style tests against an ephemeral database.

Module 5 — Delivery

Containerisation, CI/CD scaffolds, and a starter observability layer.

Start
  1. 1
    Dockerise the service
    Multi-stage Dockerfile and docker-compose for local development.
  2. 2
    CI/CD starter
    GitHub Actions pipeline: build → test → publish image.
  3. 3
    Starter observability
    Structured logging, basic metrics, health endpoints.
