Create Agentic App

Walk the user from "I want to build something" to a verified, running Agentic Coding Starter Kit project at http://localhost:3000. Every step has a clear purpose — explain it briefly to the user as you go, so they understand the choices being made on their behalf.

All shell commands below are written in POSIX form. On Windows, run them through the Bash tool (Git Bash / WSL), which is available on every supported platform. Do not translate to PowerShell unless a command actually fails.

This skill is linear with two real branch points: folder strategy (Step 2) and database choice (Step 6). Everything else is a yes/no or a default. Move through the steps in order — skipping ahead breaks assumptions downstream (e.g. migrations require a configured POSTGRES_URL).

<pm> substitution: Throughout this file and the references, <pm> is a placeholder for the chosen package manager — substitute as follows:

Detect what the user already has installed before asking them to pick anything. Probing first means later questions only offer real options — nothing is worse than asking "pnpm or npm?" and then discovering pnpm isn't installed.

Run all six probes in parallel via a single batch of Bash calls:
