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.

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 | $0.00147 | $0.00147 |
| Opus 5.5 | $0.00059 | $0.00059 |
| Sonnet 5.5 | $0.00029 | $0.00029 |
| Haiku 4.5 | $0.00015 | $0.00015 |
Grade A, and why
ssgoi AGENTS.md 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 2mo 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
SSGOI
Releasing
Every package under packages/* is versioned in lockstep by
scripts/bump-version.mjs; pnpm release builds and publishes them together.
A version bump is not finished until apps/docs/public/llms.txt says the new
version. Update the Current version: line near the top of that file in the
same change as the bump.
That file is not a generated artifact — it is the URL the docs quick start hands to coding agents as the whole setup guide. A stale version there is the version that gets installed, in every project that asks an agent to add SSGOI, until someone notices by hand.
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.
