Working with mise

Overview

mise is a polyglot tool version manager. Use this skill when:

• Adding tools to a project via mise
• Troubleshooting "command not found" when mise should have tools available
• Deciding whether mise is the right choice for a dependency

The Iron Rules

1. Use mise use to add tools - never manually edit config files
2. Detect existing config files first - don't create new ones when one exists
3. Fix the shell, don't workaround - if tools aren't on PATH, diagnose the activation issue rather than using mise exec as a permanent workaround

When to Use mise vs Alternatives

Use mise when version matters per-project
