description	Creates a topic-specific directory and file tree scaffold (Gerüst) as a starting point for a software solution or skill collection. Generates empty files, adds placeholder.txt in every empty directory so git tracks it, and writes a README.md in the root with metadata: topic, version, description, create timestamp (YYYYMMDD_HHMISS), creator, and license. Activate for phrases like: "create a file tree for", "scaffold a project for", "create directory structure for", "bootstrap a file scaffold", "Gerüst für", "starting point for", "create folder structure", or "new project skeleton".

Create File Tree for Topic

Creates a topic-specific directory and file tree scaffold as a clean starting point for a software solution or a skill collection.

What this skill produces

<topic>/
├── README.md                  ← metadata header (see format below)
├── src/
│   └── placeholder.txt        ← keeps empty dir in git
├── tests/
│   └── placeholder.txt
├── docs/
│   └── placeholder.txt
└── ...                        ← topic-specific dirs + empty files

All files are empty except README.md and placeholder.txt files.

Step-by-step workflow

Step 1 — Collect inputs

Ask the user for (or derive from context):

Input	Required	Default / Fallback
topic	✅	—
description	✅	ask user
version	✅	0.1.0
license	✅	MIT for SW topics · CC BY-NC-SA 4.0 for skill collections
creator	optional	run git config user.name; if empty → ask user
language	optional	en

License selection rule:

• SW project (code, tool, library, app) → MIT
• Skill collection, methodology, learning content → CC BY-NC-SA 4.0
• When in doubt → ask the user.

Step 2 — Brainstorm the tree

Based on the topic, propose a meaningful directory and file structure. Apply KISS: start small. Typical patterns:

SW project (e.g. "cli-todo-app"):

<topic>/
├── README.md
├── src/
│   └── placeholder.txt
├── tests/
│   └── placeholder.txt
├── docs/
│   └── placeholder.txt
└── .gitignore               ← empty

Skill collection (e.g. "stoicism-skills"):

<topic>/
├── README.md
├── skills/
│   └── placeholder.txt
├── references/
│   └── placeholder.txt
└── assets/
    └── placeholder.txt

Python package:

<topic>/
├── README.md
├── src/
│   └── <topic>/
│       ├── __init__.py      ← empty
│       └── placeholder.txt
├── tests/
│   └── placeholder.txt
├── docs/
│   └── placeholder.txt
├── pyproject.toml           ← empty
└── .gitignore               ← empty

Present the proposed tree to the user as a fenced block. Wait for confirmation before creating any files.

Step 3 — Generate the timestamp

date +"%Y%m%d_%H%M%S"
# Output example: 20240324_142305
# Format: YYYYMMDD_HHMISS  (HH=hour, MI=minutes, SS=seconds)

Resolve creator:

CREATOR=$(git config user.name 2>/dev/null)
if [ -z "$CREATOR" ]; then
  # Ask the user: "Who should be listed as creator?"
fi

Step 4 — Write README.md

Use this exact template in the root README.md:

# <topic>

> <description>

## Scaffold Metadata

| Field       | Value                        |
|-------------|------------------------------|
| Topic       | <topic>                      |
| Version     | <version>                    |
| Created     | <YYYYMMDD_HHMISS>            |
| Creator     | <creator>                    |
| License     | <license>                    |
| Language    | en                           |

## Structure

\`\`\`
<paste the confirmed tree here>
\`\`\`

## Getting Started

<!-- Add setup instructions here -->

## Notes

<!-- Add any additional context here -->

Step 5 — Create directories and files

For every directory in the confirmed tree:

• Create the directory.
• If the directory has no other files in it (i.e. only a placeholder.txt is listed), create placeholder.txt with this content:

# placeholder
# This file exists so git tracks this otherwise empty directory.
# Remove it once you add real files here.

For every named empty file in the tree (e.g. .gitignore, pyproject.toml, __init__.py): create it with zero bytes.

Step 6 — Confirm and summarise

After creating all files, print a summary:

✅ Scaffold created for topic: <topic>
   Root: ./<topic>/
   Files created: <N>
   Timestamp: <YYYYMMDD_HHMISS>
   Creator: <creator>
   License: <license>

Next steps:
  cd <topic>
  git init
  git add .
  git commit -m "chore: initial scaffold for <topic>"

Rules

• KISS: prefer flat over deep. Max 3 levels unless the topic demands it.
• No content: all non-README files are empty placeholders unless the user explicitly requests seed content.
• placeholder.txt only in empty dirs: never add placeholder.txt next to real files.
• Ask before creating: always show the proposed tree and wait for user confirmation before touching the filesystem.
• Idempotent: if the root directory already exists, warn the user and stop — do not overwrite.

Scripts

A helper script is available at scripts/create-file-tree.sh for generating the scaffold from the command line. See that file for usage.
