How is the sd skill better than using the standard sed command?

The sd skill is significantly faster than sed and utilizes a much more intuitive JavaScript-style regex syntax, preventing 'escape hell' and making complex patterns easier to write and maintain.

What is the recommended workflow for project-wide replacements?

The most effective workflow is to use a discovery skill like ripgrep to find patterns, then pipe those results into the sd skill for targeted, batch replacements.

Can I preview changes before they are applied to my files?

Yes, the sd skill includes a --preview option that allows you to dry-run replacements, ensuring your patterns are correct before any permanent changes are written to disk.

Does the sd skill support capture groups for complex replacements?

Absolutely. You can use capture groups like $1, $2, or ${var} to extract and rearrange specific parts of a matched string during the replacement process.
