Add PACKAGE_INSTALLATION_GUIDE.md with three approaches for pre-installing packages in Workbench apps: 1. Devcontainer Features (easiest for R packages) - Use ghcr.io/rocker-org/devcontainer-features/r-packages - Simple comma-separated package list - Auto-installs system dependencies 2. Custom Dockerfile (best for Python packages) - Add RUN pip install commands - Cached in image layers for fast startup - Full version control 3. Post-create scripts (most flexible) - Supports mixed R + Python environments - Dynamic installation from requirements.txt Includes: - Complete working examples (R Analysis, Jupyter ML/AI stack) - Comparison table showing when to use each approach - FAQ section addressing common questions - Copy-paste templates for quick setup This addresses the common user need to avoid running pip install or install.packages() every time they create an app, without requiring the complexity of custom app options.

Add a devcontainer feature that solves the common use case: users want
specific packages pre-installed to avoid running pip install or
install.packages() every time they create an app.
Features:
- Curated package presets (basic, ml, bio, full)
- Works for both Python and R
- Custom package support on top of presets
- No Dockerfile needed - just add to .devcontainer.json
Example usage:
{
"features": {
"ghcr.io/verily-src/workbench-app-devcontainers/common-packages": {
"pythonPackages": "basic",
"customPythonPackages": "mypackage",
"rPackages": "basic",
"customRPackages": "zoo,forecast"
}
}
}
This is simpler than custom app options for the common case where users
just want "R Analysis with these 15 packages".
Also updated PACKAGE_INSTALLATION_GUIDE.md to feature this approach first.

Remove presets. Users just specify their package list:
{
"features": {
"common-packages": {
"pythonPackages": "pandas numpy scikit-learn",
"rPackages": "tidyverse,ggplot2,dplyr,plotly,shiny"
}
}
}
This solves the exact use case: 'R Analysis with these 15 packages
pre-installed' without the complexity of custom app options.

Enables workflow: User: 'I want R with tidyverse, ggplot2, plotly' Claude: Generates complete devcontainer directory with those packages pre-installed Output can go in user's own repo - doesn't need to be in workbench-app-devcontainers. Skill teaches Claude to use the common-packages feature for package pre-installation. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
- Renamed skill to CREATE_CUSTOM_APP_WITH_PACKAGES (not just R) - Feature works for Jupyter, VSCode, RStudio, etc. - Supports both Python and R packages - Simplified documentation Users can request any app type with any packages: - 'I want Jupyter with pandas and numpy' - 'I want VSCode with tensorflow' - 'I want R with tidyverse' Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Problem
Users want a few specific packages pre-installed so they don't have to run pip install or install.packages() every time they create an app. Custom app options are too complex for simple cases like "R Analysis with these 15 packages."
Solution
R packages:
Packages are pre-installed. No install.packages() needed every app
launch.
What's Added
package list
Impact
Users can pre-install packages with one line - simpler than custom
app options.
