SSGOI is a browser-based page-transition library that adds app-like animated navigation to mobile websites, progressive web apps, and WebViews. It works with existing routers and server-rendered applications across major browsers and supports frameworks including React, Svelte, Vue, Solid, Angular, and Qwik. The catalogue skills, instructions, and plugin help coding agents apply SSGOI to supported web projects.
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.

What it costs to keep this loaded
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 | $0.00026 | $0.00397 |
| Opus 5.5 | $0.00010 | $0.00159 |
| Sonnet 5.5 | $0.00005 | $0.00079 |
| Haiku 4.5 | $0.00003 | $0.00040 |
Grade A, and why
verify scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Verify apps/docs
Launch
cd apps/docs && pnpm dev # Next.js + Turbopack, ready in <1s on :3000
Wait for Ready in in the log. Port 3000; kill with lsof -ti:3000 | xargs kill.
Drive
Playwright is installed globally (asdf node), not in the repo. From a scratch
dir, symlink the global modules so import { chromium } from "playwright"
resolves:
ln -sfn "$(npm root -g)" <scratchdir>/node_modules
Use a 1280x960 viewport — the mobile demos render a centered phone frame on desktop widths. Key surfaces:
- Mobile demos:
/demo/<app>(e.g./demo/google-photos). Transitions are the product — capture mid-transition frames withwaitForURL+ ~120ms delay, and let animations settle ~1200ms before asserting final state. - Remount checks: tag a DOM node (
el.__tag = "x") before navigating, re-read after — survives ⇔ no remount (used for the bottom-nav/nested-boundary shell). - Docs pages:
/docs/...; llms files are static frompublic/(/llms.txt,/llms/*.txt).
Gotchas
- google-photos "Collage" entry is a
<button>withrouter.push, not a link. - Dev console shows a pre-existing CORS error for
unpkg.com/react-grab— noise. - Stale
.next/typesvalidator errors after moving route files — ignore; regenerated on next dev/build.
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.

verify is a skill published in the GitHub repository meursyphus/ssgoi (1,013 stars, last pushed 11d ago), licensed MIT. It adds 26 tokens to every session and 397 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

Generates Playwright page objects from an executable test plan, one class per screen with ladder-compliant locators and no assertions, wired into a shared fixture. Use when a web scenario needs a page object that does not exist yet, or when locators drift and the page object must be rebuilt.

Optimize the meaningful UI available immediately from a Next.js route on an initial load (hard navigation) or named client-side navigation (soft navigation). Encode the goal as a failing @next/playwright instant() e2e and work it to green, one verified route and entry point at a time; the shipped test then guards…
