Can I use this to migrate from nvm or pyenv?

Yes, the skill provides specific migration patterns to document your current versions, transfer them to a mise.toml file, and transition to a single unified manager.

What should I do if a tool installed via mise is not found?

The skill provides a troubleshooting checklist to verify shims in your PATH, check shell configuration files, and use 'mise reshim' to regenerate necessary tool links.

How does this skill improve shell startup performance?

Unlike legacy managers that add 50ms+ latency per tool, this skill implements mise's optimized shim system which reduces total shell startup time to approximately 10ms.

Why does the skill recommend uv over pip for Python?

Following 2024-2025 best practices, uv provides significantly faster and more reliable dependency management and tool isolation than traditional pip installations.
