C1 — Command Shadows

Disabling __fish_config_op_aliases restores standard system behavior for all of these commands.

Command / Alias	Active behavior	Disabled fallback
`ls`	eza -l -a –icons –hyperlink	system ls
`cat`	bat syntax-highlighted; dirs → ls	/usr/bin/cat
`cd`	zoxide frecency-based navigation	fish builtin cd
`rm`	moves files to trash (recoverable)	command rm (permanent)
`less`	$PAGER → ov → less → more → cat	system less
`du`	duf (disk overview) or dust (dir tree)	system du
`top`	btop resource monitor	system top
`ping`	prettyping –nolegend animation	system ping
`ssh`	kitten ssh in Kitty terminal	system ssh
`rg`	rg –hyperlink-format=kitty	system rg
`mkdir`	verbose path-tree display on creation	mkdir -p silently
`bash`	XDG bashrc + $SHELL reset on exit	system bash
`history`	timestamps prepended to every entry	fish builtin history
`cp / mv`	forced -i confirmation prompt	cp / mv unmodified
`wget`	forced –continue (resume downloads)	system wget
`grep/fgrep/egrep`	forced –color=auto	system grep variants
`dir / vdir`	forced –color=auto	system dir / vdir
`help config`	intercepts “help config” → config-help	fish builtin help
`claude`	auto-links AGENTS.md as CLAUDE.md before launch	command claude
`edit`	multi-editor launcher (GUI/term + fallbacks)	$EDITOR/nvim/nano/vi

When C1 is disabled, rm uses bare command rm with no wrapper — files are permanently deleted, not trashed. There is no intermediate safety net.

Sub-categories

__fish_config_op_aliases sub-divides into six sub-categories, each with its own __fish_config_op_aliases_<slug> toggle:

ls, cat, cd, du, mkdir, rm, mv, and cd/zoxide navigation – the everyday filesystem-inspection and -modification shadows.

rg, with its Kitty hyperlink formatting.

ping, ssh, and yt-dlp – shadows that talk to the network.

top -> btop.

bash (XDG bashrc + $SHELL reset), less ($PAGER fallback chain), and the help config interception.

claude (AGENTS.md/CLAUDE.md auto-linking) and edit (multi-editor launcher), plus agy.
