Ultrapowers Dev

54 development skills for your coding agents — language best practices for 13 languages, 12 framework patterns, 7 agentic patterns, and architecture fundamentals. A companion plugin to Ultrapowers.

Documentation · GitHub · Issues

How it works

These skills give your coding agent deep expertise across languages, frameworks, and architectural patterns. When your agent encounters a React component, a FastAPI endpoint, or a Rust service, it automatically applies the right patterns and best practices.

Each skill is self-contained and triggers automatically when relevant. No special commands needed — your agent just has development superpowers.

Example

"Refactor our Express API to FastAPI."

The agent automatically applies express-patterns to understand the existing code, python-best-practices and fastapi-patterns for the migration, api-design for endpoint conventions, error-handling for proper Result patterns, and testing-tdd to ensure every endpoint has coverage before and after the switch.

Installation

Claude Code (via Ultrapowers Marketplace)

Register the marketplace first (one time):

/plugin marketplace add ennio-datatide/ultrapowers

Then install:

/plugin install ultrapowers-dev@ultrapowers

From Source

git clone https://github.com/ennio-datatide/ultrapowers-dev.git

Verify Installation

Start a new session and ask for something that should trigger a skill (for example, "build a FastAPI endpoint" or "review this React component"). The agent should automatically invoke the relevant skill.
