+# Plan: prompty-dumpty DevContainer Feature
+
+Install prompty-dumpty (v0.6.2 current) Python package system-wide using pip3 with `--break-system-packages` flag. The CLI command `dumpty` will be available globally after installation.
+
+## Steps
+
+1. **Create feature structure** at `src/prompty-dumpty/` with `devcontainer-feature.json` (id: "prompty-dumpty", version option only with default "latest", no `installsAfter` or installPath), `README.md` documenting the `dumpty` command, and `.gitignore`
+
+2. **Write install script** at `src/prompty-dumpty/install.sh` with `set -e` for fail-fast behavior, detect package manager (apt/apk/yum), install `python3-pip` if missing, run `pip3 install prompty-dumpty --break-system-packages` (latest) or `pip3 install prompty-dumpty==VERSION --break-system-packages` (specific version like 0.6.2)
+
+3. **Add verification and output** using `command -v dumpty` to verify installation, run `dumpty --version`, display colored success message with installation details following `src/microsoft-security-devops-cli/install.sh` colored output pattern
+
+4. **Create test suite** at `test/prompty-dumpty/` with `test.sh` (installs latest, verifies `dumpty` exists), `version.sh` (installs version 0.6.2 specifically), and `scenarios.json` testing both scenarios on debian/ubuntu base images
+
+## Further Considerations
+
+None - ready to implement with fail-fast on errors and pip's default install paths.

+# Prompty Dumpty (prompty-dumpty)
+
+Installs prompty-dumpty CLI tool for managing prompty files
+
+## Example Usage
+
+```json
+"features": {
+    "ghcr.io/rosstaco/devcontainer-features/prompty-dumpty:1": {}
+}
+```
+
+## Options
+
+| Options Id | Description | Type | Default Value |
+|-----|-----|-----|-----|
+| version | Version of prompty-dumpty to install. Use 'latest' or a specific version like '0.6.2' | string | latest |
+
+## Usage
+
+After installation, the `dumpty` command will be available:
+
+```bash
+dumpty --help
+dumpty --version
+```
+
+## Notes
+
+This feature installs prompty-dumpty system-wide using pip3 with the `--break-system-packages` flag, which is appropriate for containerized development environments. Python 3 is assumed to be present in the base image.
