backend-setup-stack

backend-setup-stack is a skill for Claude Code, Codex from WESTsyre21/setup-backend-stack. It costs 54 tokens per session (1,965 once invoked), scanned A, original, MIT.

A setup guide for a local backend that runs an npm server with PostgreSQL in Docker and accesses the database through Prisma or Sequelize, an object-relational mapper (ORM). It also handles database migrations, which record changes to the database structure over time.

In plain words
What is it for?
Use it to initialize or update a local development environment, choose backend and database settings, connect the server to PostgreSQL, and set up version-controlled migrations.
Why use it?
It removes the need to assemble the server, database, ORM, containers, and migration process by hand. It also checks existing migration information and whether the database is ready.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

backend-setup-stack scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (server.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Skill: Docker + PostgreSQL + npm Server + ORM Architecture Setup

Objective

To scaffold a containerized local development ecosystem that connects an npm backend server to a Dockerized PostgreSQL instance via an ORM, establishing automated, version-controlled database migrations.

Phase 1: Environment Assessment & State Initialization

  1. Check capabilities: Confirm whether you have filesystem write access and shell execution access.
    • If yes, perform actions and report outputs.
    • If no, output exact commands and file contents and ask the user to execute them.
  2. Analyze Requirements: Scan the user's prompt for specific configuration choices:
    • If the user does not specify an ORM, select Prisma.
    • Only select Sequelize if the user explicitly includes the exact token Sequelize (case-insensitive).
    • If both ORMs are mentioned or the request is ambiguous, ask: "Which ORM do you prefer: Prisma or Sequelize?"
    • Chosen web framework (e.g., Express, Fastify).
    • Custom port preferences (default to 3000 for server, 5432 for DB).
  3. Anchor State to Disk: If you have write access, create or update .claude_history/setup_status.md in the project root with the chosen ORM, DB connection string, and initialization checklist. If you do not have write access, print the exact commands and file contents to create or update that file and ask the user to confirm.

Phase 2: Structural Scaffolding & ORM Initialization

If running as an agent with filesystem access, execute the following commands and report results. Otherwise, print the exact shell commands and file contents and ask the user to run them.

  1. Confirm Docker availability:
    • Run docker --version and docker-compose --version.
    • If either command is missing, instruct: "Install Docker Desktop (https://www.docker.com/products/docker-desktop) or run your platform's Docker install instructions" and abort further steps.
  2. Initialize npm if no package.json exists: npm init -y
  3. Install the core backend and database dependencies:
    • For Express apps: npm install express
    • For Prisma: npm install @prisma/client and npm install -D prisma
    • For Sequelize: npm install sequelize pg pg-hstore and npm install -D sequelize-cli
    • If using nodemon for development, also run npm install -D nodemon
  4. Ensure package.json contains a dev script. If absent, add one before running:
    • Example: npm pkg set scripts.dev "node server.js"
    • Or: npm pkg set scripts.dev "nodemon server.js"
  5. Trigger the ORM initialization command:
    • Prisma: npx prisma init (generates /prisma/schema.prisma and updates .env)
    • Sequelize: npx sequelize-cli init (generates /models, /migrations, /seeders, /config)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
