Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00127 | $0.02375 |
| Opus 5.5 | $0.00051 | $0.00950 |
| Sonnet 5.5 | $0.00025 | $0.00475 |
| Haiku 4.5 | $0.00013 | $0.00237 |
Grade A, and why
vercel-react-view-transitions scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to vercel-react-view-transitions — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 284 lines — stays where its author put it; the contents beside it link to each section on GitHub.
React View Transitions
Animate between UI states using the browser's native document.startViewTransition. Declare what with <ViewTransition>, trigger when with startTransition / useDeferredValue / Suspense, control how with CSS classes. Unsupported browsers skip animations gracefully.
When to Animate
Every <ViewTransition> should communicate a spatial relationship or continuity. If you can't articulate what it communicates, don't add it.
Implement all applicable patterns from this list, in this order:
| Priority | Pattern | What it communicates |
|---|---|---|
| 1 | Shared element (name) |
"Same thing — going deeper" |
| 2 | Suspense reveal | "Data loaded" |
| 3 | List identity (per-item key) |
"Same items, new arrangement" |
| 4 | State change (enter/exit) |
"Something appeared/disappeared" |
| 5 | Route change (layout-level) | "Going to a new place" |
This is an implementation order, not a "pick one" list. Implement every pattern that fits the app. Only skip a pattern if the app has no use case for it.
Choosing Animation Style
| Context | Animation | Why |
|---|---|---|
| Hierarchical navigation (list → detail) | Type-keyed nav-forward / nav-back |
Communicates spatial depth |
| Lateral navigation (tab-to-tab) | Bare <ViewTransition> (fade) or default="none" |
No depth to communicate |
| Suspense reveal | enter/exit string props |
Content arriving |
| Revalidation / background refresh | default="none" |
Silent — no animation needed |
Reserve directional slides for hierarchical navigation (list → detail) and ordered sequences (prev/next photo, carousel, paginated results). For ordered sequences, the direction communicates position: "next" slides from right, "previous" from left. Lateral/unordered navigation (tab-to-tab) should not use directional slides — it falsely implies spatial depth.
Availability
- Next.js: Do not install
react@canary— the App Router already bundles React canary internally.ViewTransitionworks out of the box.npm ls reactmay show a stable-looking version; this is expected. - Without Next.js: Install
react@canary react-dom@canary(ViewTransitionis not in stable React). - Browser support: Chromium 111+, Firefox 144+, Safari 18.2+. Graceful degradation on unsupported browsers.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

vercel-react-view-transitions is a skill published in the GitHub repository ariadoss/superskills (12 stars, last pushed 3d ago), licensed MIT. It adds 127 tokens to every session and 2,375 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to vercel-react-view-transitions, differing in 0 lines, and is treated as a copy.
