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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00065 | $0.00364 |
| Opus 5.5 | $0.00026 | $0.00146 |
| Sonnet 5.5 | $0.00013 | $0.00073 |
| Haiku 4.5 | $0.00006 | $0.00036 |
Grade A, and why
mobile-onboarding 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
91% identical to mobile-onboarding — 3 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.
What it actually says
Mobile Onboarding Skill
Produce a three-screen mobile onboarding flow on a single HTML page.
Workflow
- Read DESIGN.md.
- Identify the app + audience.
- Layout: three phone frames side by side. Each phone:
- Status bar (time, battery, signal).
- Hero artwork or icon.
- Headline + supporting paragraph.
- 3-dot pagination.
- Primary CTA (full-width pill button).
- "Skip" or alt action top-right.
- Last phone is the sign-in / continue-with options screen.
- Strong typography, gentle gradients, accessible contrast.

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.
