agent-setup

agent-setup is an agent for coding agents from jeftarmascarenhas/context-mesh. It costs 0 tokens per session (655 once invoked), scanned A, original, MIT.

A starter project structure with an Express and TypeScript backend and a Vite, React, and TypeScript frontend. It also sets up Tailwind CSS, page routing, Prisma scaffolding, and basic folders for future features.

In plain words
What is it for?
Use it to begin a full-stack to-do application with separate frontend and backend projects, shared environment-file templates, and a basic development structure.
Why use it?
It removes the initial project setup work and establishes separate places for frontend, backend, routes, services, components, and pages. It deliberately leaves feature and database implementation for later steps.

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

agent-setup 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 3d ago.

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.

Agent: Setup - Todo App

Purpose

Initialize the project structure with backend (Express + TypeScript) and frontend (Vite + React + TypeScript).

Context Files to Load

  • @context/intent/project-intent.md
  • @context/decisions/001-tech-stack.md

Scope

  • Allowed: Root project, backend/, frontend/
  • Prohibited: Don't implement features, don't setup database

Execution Steps

  1. Create Backend Structure

    • Initialize Node.js project with TypeScript
    • Configure Express with basic middleware
    • Create directory structure (routes, services, middleware, dto)
    • Setup Prisma (schema will be created in database phase)
    • Create .env.example
  2. Create Frontend Structure

    • Initialize Vite + React + TypeScript project
    • Configure Tailwind CSS
    • Setup React Router
    • Create base directory structure (components, pages, services, context)
    • Create .env.example
  3. Create Root Files

    • Create .gitignore

Environment Variables

backend/.env.example

DATABASE_URL=postgresql://todoapp:todoapp_password@localhost:5432/todoapp
JWT_SECRET=your-secret-key-here
JWT_EXPIRES_IN=7d
PORT=3000
NODE_ENV=development

frontend/.env.example

VITE_API_URL=http://localhost:3000/api/v1

Definition of Done

  • Backend structure created with Express + TypeScript
  • Frontend structure created with Vite + React + TypeScript
  • Directory structure organized
  • Environment variables template created
  • pnpm install runs in both directories
  • TypeScript compiles without errors

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.

agent-setup is an agent published in the GitHub repository jeftarmascarenhas/context-mesh (39 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 655 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
