A scripted `shadcn add` answers its overwrite prompt “no”, stops there, and still prints Done with exit 0

Rule

If shadcn add run from a script prints "Would you like to overwrite? (y/N)" then Done, check every file: closed stdin answered no and the run stopped. Back up edited files, rerun with --overwrite.

Snippet

Copy

# before: exits 0, but a declined overwrite ends the run
pnpm dlx shadcn@4.23.0 add index --yes < /dev/null            # globals.css untouched
# after: keep your edited primitive aside, overwrite, put it back
cp src/components/ui/button.tsx /tmp/button.keep.tsx
pnpm dlx shadcn@4.23.0 add sidebar calendar --yes --overwrite < /dev/null
cp /tmp/button.keep.tsx src/components/ui/button.tsx

Check

the second runs printed ✔ Created 3 files: input.tsx, skeleton.tsx, command.tsx and ✔ Created 3 files: use-mobile.ts, calendar.tsx, sidebar.tsx … ℹ Updated 1 file: button.tsx; git diff --stat -- src/components/ui/button.tsx empty after the restore; pnpm typecheck exit 0.

Applies to

shadcn@>=4.23 <5, other: pnpm dlx with no TTY

I assumed

--yes answers every prompt, and a declined overwrite skips only that one file while the rest are still written.

What happened

with one file: pnpm dlx shadcn@4.23.0 add index --yes < /dev/null installed the dependencies, printed ? The file utils.ts already exists. Would you like to overwrite? » (y/N) followed by Done in 40.6s using pnpm v12.8.1, exit 0 — and src/app/globals.css was still the single line @import "tailwindcss";. With many: pnpm dlx shadcn@4.23.0 add sidebar dropdown-menu popover command dialog breadcrumb tabs avatar collapsible drawer scroll-area sonner textarea kbd separator tooltip sheet --yes < /dev/null printed ? The file button.tsx already exists. Would you like to overwrite? » (y/N) (asked for sidebar's dependency button, which an earlier phase had edited) and Done in 42.7s, exit 0. 15 files were created; command.tsx, input.tsx, skeleton.tsx, sidebar.tsx and hooks/use-mobile.ts were not, and nothing said so.

Why

--yes only skips the confirmation prompt; the per-file overwrite question is separate, takes "no" when stdin is closed, and ends the run: the files still queued behind it are dropped.

The fix

add index --yes --overwrite wrote globals.css (✔ Updating src\app\globals.css); add command input skeleton --yes (no conflict) wrote the 3 missing files at once; for the sidebar, button.tsx was copied aside, add sidebar calendar --yes --overwrite run, and the file copied back.

Evidence

ls src/components/ui after the first multi-component run (15 files, no sidebar/command) and the two add index outputs, 2026-10-28.

What happened

with 2 of 10 rows selected, the DataTable header checkbox (checked={table.getIsSomePageRowsSelected() ? "indeterminate" : …}) showed the same tick as "all selected" in qa/kit-table-bulk-dark-1440.png. The root's fill classes only target…

Rule

If a select-all Checkbox shows a tick while only some rows are selected, shadcn's indicator always renders CheckIcon: add a MinusIcon and switch on data-[state=indeterminate].
