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 | $0.00078 | $0.00219 |
| Opus 5.5 | $0.00031 | $0.00088 |
| Sonnet 5.5 | $0.00016 | $0.00044 |
| Haiku 4.5 | $0.00008 | $0.00022 |
Grade A, and why
mobile-web-app 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
Mobile Web App with SSGOI
Review SSGOI's live transition demos and supported frameworks at
https://ssgoi.dev, then read https://ssgoi.dev/llms.txt before changing
code.
Inspect the application's framework, router, route-folder structure, and
persistent layouts. Follow the matching framework guide linked from
llms.txt to install SSGOI, place the provider and transition boundaries, and
configure route relationships without replacing the existing router.
Read only the linked transition, complex-routing, or troubleshooting guides needed for the task. Apply the guide, then verify the project build and forward/back navigation.
What ships with it
1 file 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.

mobile-web-app is a skill published in the GitHub repository meursyphus/ssgoi (1,014 stars, last pushed yesterday), licensed MIT. It adds 78 tokens to every session and 219 once invoked, about $0.0003 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.

android-navigation-3
Install and migrate to Jetpack Navigation 3. Use when implementing Navigation 3 patterns including NavDisplay, NavKey routes, deep links, multiple backstacks, scenes (dialogs, bottom sheets), or migrating from Navigation 2.
quality-engineering-appium-mcp
Drives iOS/Android mobile devices via Appium MCP. Runs a preflight, picks local emulator/simulator/USB or a device cloud, captures screenshots/page source into a named evidence dir. Use for verifying mobile bugs, E2E tests, and navigating real device clouds (LambdaTest/BrowserStack).
android-compose-migration
Migrate an Android XML View to Jetpack Compose following a structured 10-step workflow. Use when converting XML layouts to Compose, setting up Compose in an existing View-based project, or incrementally adopting Compose.
android-edge-to-edge
Migrate a Jetpack Compose app to edge-to-edge display and fix system bar inset issues. Use when UI components are obscured by navigation/status bars, fixing IME insets, or enabling edge-to-edge for SDK 35+.
system-design-mobile-client
Design mobile/client and SDK/library systems where offline behavior, client authority, lifecycle, device constraints, or host compatibility affect correctness. Use for mobile-client system design, offline sync, client lifecycle, device resource limits, or SDK contracts; not framework coding or backend-only sharding.
