Hey folks, I'm working on an experimental CLI which uses the tsgo toolchain to find optional component and function signatures that are in practice never passed. This is essentially dead code elimination, and a complementary workflow to run alongside a tool like knip.

The changeset in this PR has been done using the script as the reporting tool, and an agent validator loop walking through each reported line one by one to first inspect the report, analyze the call sites, removing them, and later re-running ts. If done correctly, the code that has been removed should have been effectively dead.

The reporting script heavily relies on type quality and only reports on types whos members are statically enumerable.

I'm opening this PR in an effort to help you eliminate dead code, but also to gain feedback on the script and the detection mechanisms. There are always risks of false positive reports, and removal of code that is actually still required at runtime.

Some references of PRs opened to other repositories that have been merged or are still open:
Sentry (4k loc removed)
Sentry (followup 1k loc removed)
Tanstack (this PR)

Would love to hear your feedback 🙏🏼

Review Change Stack

📝 Walkthrough

Walkthrough

This change removes optional configuration across builder APIs, UI components, hooks, queries, server utilities, and data helpers. Components and services now use fixed labels, layouts, limits, destinations, timings, and default data sources.

Changes

Contract simplification

Layer / File(s) Summary
Builder and runtime contract updates
src/auth/oauth.server.ts, src/builder/api/*, src/utils/application-starter.ts, src/utils/github-repo.server.ts, src/utils/intent-*.server.ts, src/utils/notebook-*
Builder metadata, feature artifacts, repository operations, intent workflows, OAuth exchange, and notebook utilities remove injectable options and use fixed behavior.
Application and shared UI behavior
src/components/ApplicationStarter.tsx, src/components/*, src/components/ds/*, src/ui/*
Shared components remove optional props and use fixed rendering, styling, labels, dimensions, links, and interaction behavior.
Commerce, statistics, and admin flows
src/components/npm-stats/*, src/components/shop/*, src/routes/admin/*, src/routes/-shop-browse.tsx, src/libraries/*, src/server/sponsors.ts, src/utils/sponsors.functions.ts
Shop, statistics, admin, maintainer, sponsor, showcase, and library paths use reduced contracts and fixed query or display behavior.
Hooks and server utility behavior
src/hooks/*, src/utils/*, src/server/*
Hooks and server utilities remove configurable callbacks, thresholds, dates, limits, request data, branches, and runtime overrides.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 72315

The cleanup removes props that are still used by the account menu and library status badge, causing type-check failures and potentially removing user profile images. The PR is not merge-ready until those consumers or component contracts are corrected.

647-657: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Restore the Avatar image contract.

Line 647 removes image and oauthImage, but src/components/AuthenticatedUserMenu.tsx passes both props to Avatar. Type checking rejects that call. The account menu also loses user profile images if the call site is changed without restoring equivalent rendering.

Restore these props and image rendering, or update the consumer with an equivalent image-capable component. The PR objective requires unchanged appearance.

Migrate the remaining rounded consumer.

src/components/LibraryStatusBadge.tsx still passes rounded="md". Type checking rejects the removed prop. Moving rounded-md into that component's className preserves its prior shape because Badge merges caller classes after rounded-full.

Proposed consumer update
 <Badge
   variant={libraryBadgeVariants[badge]}
-  rounded="md"
   className={twMerge(
+    'rounded-md',
     'font-ds-mono text-ds-mono-caps-xs uppercase',

196-197: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Remove the dead compact code path.

compact is now a constant false. Every compact branch in this component is unreachable. This includes the hotkey guard at Line 693, the compact header at Lines 724-735, the mt-3 form class at Line 738, and the complete compact form branch at Lines 744-920. The PR removes unused options, so this dead branch should also go.

Delete the constant and the unreachable JSX, then keep only the non-compact rendering path.

♻️ Suggested first step
   const palette = toneClasses[tone]
-  const compact = false
   const isHomeStarter = context === 'home'

Then replace enableHotkeys && !compact && hasFocusedPromptInput with enableHotkeys && hasFocusedPromptInput, drop the compact ? … : null header, fix the form class to 'space-y-3 mt-0', and keep only the else branch of the compact ? … : … form body.

Simplify the props type and the stale comment.

The component now renders one logo only. Omit<…, 'size'> remains from the removed size union, and the comment at Line 4 still says "Default (large) size". Use React.HTMLProps<HTMLDivElement> directly and update the comment.

-type LogoQueryGGProps = Omit<React.HTMLProps<HTMLDivElement>, 'size'>
