Current use and fit

Growing modern terminal support makes it a useful link enhancement alongside MXP and plain text.

Implementation essentials

  • Detect support where possible.
  • Emit standards-compatible URLs and provide a visible text fallback.
  • Sanitize link destinations and labels.

Compatibility and safety notes

  • Client-specific extensions are not universal OSC 8.
  • Do not hide essential commands behind links alone.
