Our review

Instantiates a project from a Bootstrapp template bundle by reading the template specification, resolving parameters with defaults, and executing the Bootstrapp script.

Strengths

  • Automates project scaffolding from a template.
  • Handles parameter defaults and dependencies.
  • Supports Xcode projects.
  • Provides clear error messages when parameters are missing.

Limitations

  • Requires the Bootstrapp template to be present locally.
  • Only works with templates that have defaults for all parameters.
  • The script path is fixed to the skill's directory.
When to use it

When you need to create a new project from a Bootstrapp template with all required parameters having defaults.

When not to use it

When the template requires user interaction for missing parameters beyond defaults, or when you need a more interactive project generation.

Security analysis

Safe
Quality score88/100

The skill runs a locally bundled Python script with user-provided parameters. It does not perform external downloads, destructive operations, or data exfiltration. Quoting instructions mitigate shell injection risk.

Examples

Basic template instantiation
Instantiate a new project from the Bootstrapp template at ~/templates/react-app
Xcode project scaffolding
Use the bootstrapp skill to scaffold an Xcode project from the template at /path/to/xcode-template

Bootstrapp Template Instantiation

The user wants to instantiate a template. The template path is: $ARGUMENTS

Instructions

Step 1: Read the template spec

Read Bootstrapp.json inside the template path. Also read Bootstrapp.md if it exists and show its contents to the user.

Step 2: Resolve parameters using defaults

Read the parameters array from the spec. For each parameter, use its default value. Skip parameters whose dependsOn references a parameter that evaluates to false.

If ANY parameter does NOT have a default value, ABORT. Do not run the script. Instead, list ALL parameters in a table showing:

  • Parameter ID
  • Type (String, Bool, Option)
  • Default value or MISSING

Tell the user which parameters are missing defaults and ask them to provide values.

Step 3: Run the script

Only run this if ALL parameters have values (from defaults or user-provided).

The script is at scripts/bootstrapp.py relative to this skill's directory.

python3 scripts/bootstrapp.py "<template-path>" \
  --param KEY1=VALUE1 --param KEY2=VALUE2 \
  --exclude-package NAME \
  --verbose
  • Include ALL resolved parameters.
  • Quote values with spaces: --param "COPYRIGHT_HOLDER=Apparata AB"
  • For Option params, pass the option string: --param LICENSE_TYPE=MIT
  • For Bool params, pass true or false: --param GIT_INIT=false
  • Include all packages by default (no --exclude-package unless the user says otherwise).

Step 4: Report result

The script prints the output path as its last line to stdout. Tell the user the full path. For Xcode projects, mention they can open the .xcodeproj.

Then ask if they want to open the output directory in Finder (open "<path>").
