AGENTS/functions/CLAUDE.md is git-ignored local agent state, not part of the repo -- a comment/commit referencing it as the schema's home points contributors at a file they can't see. The canonical CLASSIFICATION schema now lives at docs/function-classification-schema.md (tracked), with CONTRIBUTING.md's existing function-header-conventions section extended to introduce it, and the C1 shadow doc's pointer updated to match. AGENTS/functions/CLAUDE.md keeps only a one-line pointer to the tracked file instead of duplicating the definitions.

title: 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
|
|

|
|
claude auto-links AGENTS.md as CLAUDE.md before launch command claude

|
|
|
|
When C1 is disabled, `rm` uses bare `command rm` with no wrapper — files
|
|
are permanently deleted, not trashed. There is no intermediate safety net.
|
|
|
|
`history` itself is never shadowed — every function in this config that
|
|
reads history depends on its stock builtin semantics. `pretty-history`
|
|
(same `aliases-tricks` toggle) is a separate command that prints history
|
|
with a timestamp prepended to every entry.
|
|
|
|
## Sub-categories
|
|
|
|
`__fish_config_op_aliases` sub-divides into six sub-categories, each with
|
|
its own `__fish_config_op_aliases_<slug>` toggle:
|
|
|
|
## filesystem
|
|
|
|
`ls`, `cat`, `cd`, `du`, `mkdir`, `rm`, `mv`, and `cd`/zoxide navigation --
|
|
the everyday filesystem-inspection and -modification shadows.
|
|
|
|
## search
|
|
|
|
`rg`, with its Kitty hyperlink formatting.
|
|
|
|
## network
|
|
|
|
`ping`, `ssh`, and `yt-dlp` -- shadows that talk to the network.
|
|
|
|
## monitor
|
|
|
|
`top` -> `btop`.
|
|
|
|
## shell-tools
|
|
|
|
`bash` (XDG bashrc + `$SHELL` reset), `less` (`$PAGER` fallback chain),
|
|
and the `help config` interception.
|
|
|
|
## dev-tools
|
|
|
|
`claude` (AGENTS.md/CLAUDE.md auto-linking) and `edit` (multi-editor
|
|
launcher), plus `agy`.
|
|
|
|
## For function authors
|
|
|
|
Calling one of these names bare from inside your own function means the
|
|
override runs whenever C1 (or its sub-category) is on — which may not be
|
|
what your function wants: a shadow can change stdout (`cat`'s syntax
|
|
highlighting, `mkdir`'s tree display), prompt interactively where none is
|
|
expected (`cp`/`mv`'s forced `-i`), or reshape output structurally (`ls`'s
|
|
icons/columns, `rg`'s hyperlink markers). If your function's logic depends
|
|
on stock behavior, bypass the shadow deterministically, regardless of the
|
|
toggle state:

a builtin nor an

(embedded in the
|
|
fish binary
|
|
itself) — see
|
|
conf.d/help.fish

for why the

own backup copy.

$EDITOR/$VISUAL

yourself if you
|
|
want a plain
|
|
editor launch.
|
|
|
|
A function's own doc header records which of these it depends on: see the
|
|
`CLASSIFICATION` label (`uses-shadow(...)` / `bypasses-shadow(...)`),
|
|
documented in full at
|
|
[`docs/function-classification-schema.md`](../../function-classification-schema.md).
