dvcrn Elite CLI Tools
PRIMARY DIRECTIVE
Prefer these modern CLI utilities over legacy POSIX tools (find, cat, sed, grep, awk, diff, man). They produce cleaner, more structured output and reduce token waste.
Note on binary names: On Debian/Ubuntu, some binaries are renamed to avoid conflicts: fd → fdfind, bat → batcat. On other distros they use their upstream names. Adapt accordingly.
