Agent Skills: Technology Stack Modernization

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

• Workspace-Hub Standards Compliance - For verification and validation
• Quantification & Metrics - For calculating modernization ROI
