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 | $0.00106 | $0.02833 |
| Opus 5 | $0.00053 | $0.01417 |
| Sonnet 5 | $0.00021 | $0.00567 |
| Haiku 4.5 | $0.00011 | $0.00283 |
Grade A, and why
page-transition-animation 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 6d 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 page-transition-animation — 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.

Page Transition Animation (Next.js App Router)
Implement page enter/exit transitions in the Next.js App Router, and fix the single most common failure: Framer Motion AnimatePresence exit animations never fire on navigation. The reason is structural — in the App Router, when navigating, Next.js unmounts the old route's content and mounts the new one almost immediately. AnimatePresence can only animate an exit if the exiting element stays mounted under a persistent AnimatePresence wrapper long enough to run the animation. Because the router swaps children out from under it, the exit is skipped. Two approaches solve this: a pathname-keyed AnimatePresence with the FrozenRouter pattern, or the View Transitions API (native / next-view-transitions).
When to use
Use when adding animated page transitions in a Next.js App Router app, when a Framer Motion exit prop does nothing on route change, when an old page disappears instantly instead of animating out, when choosing between Framer Motion and the View Transitions API for Next.js, or when debugging why AnimatePresence won't animate between routes.
Why exit doesn't fire (the core problem)
AnimatePresence detects removal of a direct keyed child. On App Router navigation:
- The wrapper must persist across the navigation. If
AnimatePresencelives in a component that itself unmounts, there is nothing left to run the exit. - The child's
keymust change per route so AnimatePresence sees "old removed, new added". - During the brief overlap, the outgoing subtree must still render its old content — but the App Router has already swapped the route context, so the outgoing tree would otherwise render the new page's data. This is what FrozenRouter fixes.
Solution A: template.tsx + keyed AnimatePresence + FrozenRouter
template.tsx is the App Router's purpose-built hook for this: unlike layout.tsx (which persists), a template remounts on every navigation, giving each route a fresh instance — ideal for per-route enter animations. Combine it with a pathname-keyed AnimatePresence and FrozenRouter for clean exit + enter.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

page-transition-animation is a skill published in the GitHub repository 2233admin/design-pipeline (9 stars, last pushed 7d ago), licensed MIT. It adds 106 tokens to every session and 2,833 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to page-transition-animation, differing in 0 lines, and is treated as a copy.
