Does this skill automatically install new tools on my system?

No, it detects available tools and suggests installation commands, but it will never perform installations without your explicit approval.

What happens if a recommended tool like 'rg' or 'fd' is missing?

The skill implements a graceful fallback to standard tools like 'grep' or 'find' while notifying you of the performance benefits of installing the modern alternative.

Can this skill help me find tools for specific tasks not in the default list?

Yes, it includes a research workflow that triggers when a task is taking longer than expected, helping you discover the latest high-performance utilities for your needs.

How does it detect which tools are installed?

It runs a lightweight detection script using Bun to check your system path and environment context, caching results to ensure there is no performance overhead.
