# Technology Stack Modernization

## Overview

This skill provides a systematic approach to modernizing technology stacks in existing projects, including updating dependencies, replacing deprecated packages, adopting modern Python features, and ensuring workspace-hub standards compliance.

## When to Use

Use this skill when:
- Updating dependencies to current stable versions
- Replacing deprecated packages with modern alternatives
- Migrating from legacy tools (Conda → UV, PyPDF2 → pypdf, Matplotlib → Plotly)
- Adopting modern Python features (3.11+ type hints, performance improvements)
- Ensuring workspace-hub standards compliance (UV, Plotly, file organization)
- Modernizing development tools (Ruff instead of Black+isort+flake8)
- Documenting technology choices and rationale

## Related Skills
