New Phase 1b in tests/run-tests.fish: catches a bare C1-shadowed-command
call in a functions/*.fish body with no matching uses-shadow(name) or
self-limiting(name) in that function's own CLASSIFICATION header. This
is exactly the check discussed after the rm and cd audits -- runtime
auto-unwrapping isn't viable in fish (there's no hook finer than
shadowing itself, and rewriting behavior invisibly at runtime is its
own footgun); a static lint using the CLASSIFICATION tag as the
declared-intentional marker is. Scoped to functions/*.fish only: the
one-function-per-file convention there makes body extraction exact
with no block-depth parser needed.
Added a new self-limiting(name) tag to the schema for the case a bare
call is safe not because the caller did anything, but because the
shadow's own logic already neutralizes the override: rm's and mkdir's
flag checks (verified precisely -- rm falls back to command rm for any
flag except a bare -r/-R/--recursive alone, which still routes to
trash; mkdir falls back to command mkdir -p for any flag, no
exception), and grep/fgrep/egrep/dir/vdir/cat's own tty auto-detection
(--color=auto, and bat's default color behavior -- verified
byte-identical to stock cat when piped, since bat also auto-disables
highlighting on a non-terminal). Explicit and durable rather than a
silent lint exemption: if a shadow's bypass condition is ever
weakened, every self-limiting site is one grep away instead of
silently wrong.
Running the first draft of the lint surfaced three more real bugs,
none previously audited:
- config-help.fish's --man pager path checks `type -q less` (proving
it wants the real less binary specifically, for less-only -R/+N
flag syntax) then called it bare, routing through our own
$PAGER -> ov -> less -> more -> cat fallback chain instead -- which
could hand those less-specific flags to a completely different
program. Now command less.
- _fish_deps_install.fish and _fish_deps_update.fish's binary-upgrade
paths cp a freshly downloaded binary over an already-installed one
with no existence guard -- the update flow's target is guaranteed to
already exist. Our cp shadow forces -i unconditionally (a plain
alias, not flag-aware like rm's), so this would hang waiting on a
confirmation prompt in any non-interactive run. Now command cp.
Same two files' lazydocker install path piped curl output into bare
bash, invoking our shell-switch wrapper instead of a plain
subshell. Now command bash.
- agents-init.fish's AGENTS.md/CLAUDE.md relocation calls mv bare in
four places; each is already guarded by a preceding test -f check on
the destination, so the -i alias was unlikely to ever fire in
practice, but explicit command mv removes the reliance on that guard
entirely rather than leaving it as the only thing standing between a
file move and an unattended hang.
The remaining ~65 flagged call sites across ~24 files were reviewed
individually and tagged self-limiting(rm)/self-limiting(mkdir)
(verified flagged with -f/-rf or -p) and self-limiting(grep)/
self-limiting(cat) (verified piped, captured, or -q/-c; none display
color to a human), plus uses-shadow(ls) for two existence-check-only
calls (cffetch.fish, ffetch.fish) whose output is redirected to
/dev/null.
Verified an agy audit of every bare rm call (the trash-routing C1
shadow) by hand rather than trusting its report. Confirmed correct:
scrub.fish's custom_rm strategy and logs.fish's Ctrl-D delete both
deliberately want trash for a real, user-facing deletion.
Confirmed and fixed three cases where a function's own throwaway
scratch file was going to the user's trash instead of being wiped:
fc.fish's edited-command tmpfile, dng2avif.fish's intermediate PNM
(inconsistent with its own failure-path cleanup two lines up, which
already used -f), and _scrollback_prune_junk.fish's junk log files
(its sibling _prune_terminal_logs.fish already documents this exact
pitfall in its header).
Also went further than the report and classified every bypasses-shadow(rm)
caller found by grep that had never been audited at all:
config-settings.fish and edit.fish (own scratch cleanup, no destructive
data at stake) and key-crypt.fish (--remove deletes the user's real
input file after encryption, genuinely destructive, already documented
in its own header as 'not a secure wipe'). Corrected scrub.fish's tag,
which was missing uses-shadow(rm) for its deliberate trash-routing
branch alongside the bypass branch it already had tagged.
Added a note to the schema doc: rm's flag-based fallback lives inside
the shadow itself, so a bare rm -f/rm -rf call is not the caller
bypassing anything -- only an explicit command rm/builtin rm earns
the tag. This is why dng2avif.fish's fix needed no CLASSIFICATION
change: it already used rm -f, which was never actually the bug --
the missing -f on line 122 was.
Audits every function's interaction with the C1-shadowed commands
(uses-shadow/bypasses-shadow) and general hazards (destructive,
network, blocking-prompt) per the CLASSIFICATION schema.
Delegated the initial mechanical sweep to agy, then reviewed every
file by hand: fixed a systemic double-blank-comment-line formatting
bug from the delegate pass, and corrected several judgment errors
found on review -- three false blocking-prompt tags where a fish
'read' was consuming piped input rather than waiting on a terminal
(open-url.fish, sbver.fish, play-media.fish, now untagged entirely),
a blocking-prompt tag on mkrep.fish despite its documented --yes
escape hatch, an untagged read in jobrunner.fish's own baseless
blocking-prompt claim (removed, along with a destructive tag on
cleanup of its own mktemp output -- the schema explicitly excludes
that), the same own-output-cleanup false positive on
_zellij_dump_log.fish's destructive tag, an interactive fzf-gated
confirmation on logs.fish and replay.fish's piped read misread the
same way as the first three, and a uses-shadow(mkdir) on mkcd.fish
that actually belongs to the _fish_mkdir_p helper it delegates to,
not to mkcd itself.
Replace all ad-hoc inline comments between license headers and function
declarations with consistent SYNOPSIS / DESCRIPTION / ARGUMENTS / RETURNS /
EXAMPLE blocks across all 99 project-owned functions/ files. No executable
logic, variable names, or exit codes were modified.
Completes Task #6 from AGENTS.md (Retroactive Function Documentation
Standardization).
- logs.fish: add yay category, ov-powered viewing for paru/yay (section
headers, color highlights, ==> AUR build markers) and scrollback logs
(OSC 133;A sticky prompt headers); add fzf Ctrl-D delete with Y/n
confirm and list refresh, ? toggleable help overlay; run
_scrollback_prune_junk before building file list
- _scrollback_prune_junk: new utility to remove empty, single-line, and
Kitty tab-rename noise logs before display and before max-file pruning;
called from both logs and smart_exit
- smart_exit: call _scrollback_prune_junk before counting toward max files
- conf.d/yay-wrapper.fish: auto-generate ~/.local/bin/yay logging wrapper
mirroring paru-wrapper; tees output to timestamped logs, prunes old ones
- conf.d/starship.fish: move fish_prompt from config.fish; emit OSC 133;A
after the prompt's leading newline so the marker lands on the info-bar
line rather than the blank line above it; guard with type -q starship so
clean fish sessions use built-in markers unchanged
- config.fish: remove inline fish_prompt block (now in conf.d/starship.fish);
add return sentinel at EOF to prevent tool-injected init lines from running
- completions/ov.fish: add ov tab completions
- README.md: document all of the above
