package:skills

The package:skills package provides command-line tools to discover, install, and manage AI agent skills for Dart and Flutter projects.

An agent skill is a structured set of instructions, code examples, and best practices following the Agent Skills specification. When installed in your workspace, AI coding agents, such as Cursor, Gemini, Claude Code, Cline, and Copilot, use these skills to write accurate, idiomatic code tailored to your dependencies.

You run package:skills using the dart run skills@ <command> syntax:

$ # From the root of your Dart or Flutter project:
$ dart run skills@ get

To view all available commands and flags, run dart run skills@ --help.

The package:skills package includes the following commands:

get

Discovers and installs skills provided by dependencies in pubspec.yaml. In workspaces and monorepos, dart run skills@ get discovers and installs skills across all workspace packages. Supports interactive selection (Ctrl+A to toggle all), installing all skills without prompting (--all), or targeting specific packages and skills (-p <package>, -s <skill>):

$ dart run skills@ get

content_copy

add

Adds an external Git repository as a skill source and installs its skills:

$ dart run skills@ add <git_repository_url>

content_copy

create

Scaffolds a new skill directory and template for package authors:

$ dart run skills@ create -n <skill_name> -d "<skill_description>"

content_copy

list

Displays all managed skills currently installed in your workspace:

$ dart run skills@ list

content_copy

prune

Automatically removes skills for packages that are no longer listed as dependencies in pubspec.yaml:

$ dart run skills@ prune

content_copy

remove

Removes managed skills interactively, or targets specific packages and skills (-p <package>, -s <skill>):

$ dart run skills@ remove

content_copy
