Next review available in: 19 minutes You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 WalkthroughWalkthroughAdds a SvelteKit kitchen-sink example with clean routes, defect-gallery routes, analyzer expectations, static and build-mode E2E tests, workspace configuration, documentation, and a benchmark ChangesKitchen-sink example
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR adds a runnable kitchen-sink app and regression suite, but the current head still has an unbound focus target, incomplete Svelte type validation, a gallery accessibility-count issue, and misleading benchmark output. These could cause incorrect example behavior or weaken confidence in the regression and benchmark results, so merge should wait for fixes or explicit owner acceptance.

In `@docs/superpowers/plans/2026-08-16-kitchen-sink-example.md`:
- Around line 14-21: Update the plan’s expected-entry schema and meta-test
assertions to support the design-defined renderedOnly and inert variants
alongside findings and passOnly, ensuring those entries are validated by their
intended semantics rather than requiring findings. If the design is no longer
current, add a dated supersession note instead.
In `@examples/kitchen-sink/package.json`:
- Line 9: Update the kitchen-sink typecheck script to use svelte-check with the
project tsconfig instead of tsc, add svelte-check to the package and
pnpm-workspace.yaml through the existing catalog convention, and regenerate
pnpm-lock.yaml; ensure the kitchen-sink typecheck and test commands pass.
In `@examples/kitchen-sink/src/routes/clean/`+page.svelte:
- Around line 5-9: Bind the details div used by checkStatus to detailsEl with
bind:this so the focus call targets the rendered element, and update the
interaction test to assert that document.activeElement.id is clean-details after
toggling status.
In `@examples/kitchen-sink/src/routes/gallery/`+page.svelte:
- Around line 21-31: Wrap the Gallery heading and category navigation in a main
landmark in the gallery index component, preserving the existing navigation
links. Add route-level assertions so landmark checks remain intentional only for
/gallery/a11y/landmarks.
In `@packages/vite/scripts/bench/bench.mjs`:
- Around line 90-92: Update the benchmark header in the logging statement around
the runs count to use mode-neutral wording such as “per benchmark” instead of
“per size,” so it remains accurate for both size-loop and --target modes.

tsconfig.json extends .svelte-kit/tsconfig.json, which only `svelte-kit sync` generates — vitest's oxc transform failed on a clean checkout (CI) where nothing had run sync yet. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ugin instance
SvelteKit runs `vite build` as an SSR build and spawns the client build via
a separate `vite.build({ configFile })`, which re-evaluates vite.config.ts
and constructs a fresh svelteVitals() closure. The plugin only captured
build.minify from the client build's resolved config, so the instance whose
closeBundle actually analyzes the prerendered output (the outer SSR one)
never had it and the rule silently produced no finding in build mode.
Read the user's build.minify in the `config` hook instead — the same value
SvelteKit forwards to its client build — so it is captured on every
instance, including projects with no client build at all (all routes
csr: false).

With the plugin reading build.minify from its config hook, the rendered expectation flips from the pinned 0 to 1 and the known-limitation notes go. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…y landmark typecheck now runs svelte-check (templates included) with the gallery and crash samples excluded, matching the oxlint carve-out; the clean canary's focus target gets its bind:this; the gallery index gains a <main>; the bench header wording is mode-neutral; the plan documents the renderedOnly/inert expectation variants the spec already defines.

…sr-disabled rendered contract The standalone dev/test commands need the workspace dist built first. The rendered expectations correctly count seo/ssr-disabled — build mode scans Kit modules from source, so the finding survives even though the route prerenders no HTML — and the spec now says so instead of the opposite.

Summary
Adds
examples/kitchen-sink— a real, runnable SvelteKit app inside the monorepo that demonstrates every rule end to end (collection → composition → scoring → reporting), per the design indocs/superpowers/specs/2026-08-16-kitchen-sink-example-design.md. It serves four jobs at once:expected-findings.jsonpins each rule's finding count against the built CLI (run as a child process — the same artifact users run). A meta-test asserts the file covers exactlyallRules, so a future rule fails CI until it gets a gallery sample. Reasoned variants cover the edge classes:passOnly(mutually exclusive failing states, e.g. the robots.txt family),renderedOnly(rules that emit nothing in static mode),inert(gates that never open here)./clean/*routes exercise historically FP-prone patterns (spread props on presence-checked elements, per-branch landmarks,tabindex="-1", keyed lists) and are asserted to zero findings from the full report.vite buildruns in-test with the plugin, the gallery's critical findings make the gate fail the build by design, and the test reads the report fromoutFile(written before the throw) — pinning both the gate contract and the rendered-mode counts (expected-findings.rendered.json, key-set-locked to the static file).pnpm --filter kitchen-sink devserves the live dashboard against the gallery;pnpm bench --target examples/kitchen-sinktimes a real project (synthetic--sizesstays the scaling instrument).Dogfooding already paid for itself during implementation: two real engine bugs were discovered and filed separately (same-
rel<link>collapse in composed heads; the build-mode plugin losing itsminifyflag when SvelteKit's prerender pass re-instantiates it).Notes for reviewers
private: truewith nobuildscript — rootpnpm build/pnpm testand the floor-smoke job never build it; itsvite buildruns only inside the e2e test.app.htmlwithout doctype/lang,build.minify: false, robots.txt without aSitemap:line, and the never-imported crash samples undersrc/lib/crash-samples/(glob-collected by the scanner, but importing them would crash prerender).Test plan
