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 | $0.00081 | $0.01392 |
| Opus 5 | $0.00041 | $0.00696 |
| Sonnet 5 | $0.00016 | $0.00278 |
| Haiku 4.5 | $0.00008 | $0.00139 |
Grade A, and why
mobile-friendly 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 mobile-friendly — 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.
How it starts
The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SEO Technical: Mobile-Friendly
Guides mobile-first indexing optimization and mobile usability. Google uses the mobile version of pages for indexing and ranking; mobile-friendliness is a ranking factor.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Scope (Technical SEO)
- Mobile-first indexing: Google primarily crawls and indexes mobile version
- Mobile adaptation: Responsive design, viewport, breakpoints
- Content parity: Mobile and desktop content should match (or mobile preferred)
- Mobile usability: Viewport, font size, touch targets, no intrusive interstitials
- AMP: Accelerated Mobile Pages—status and when to consider
Initial Assessment
Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for site URL.
Identify:
- Site type: Responsive, separate AMP, dynamic serving
- Content parity: Does mobile show same content as desktop?
- Tools: GSC Mobile Usability report; Mobile-Friendly Test
Mobile-First Indexing Requirements
| Requirement | Action |
|---|---|
| Content parity | Mobile version must include same primary content as desktop; avoid hiding key content on mobile |
| Structured data | Same schema on mobile and desktop; ensure mobile URLs in schema |
| Metadata | Same title, meta description on mobile |
| Media | Images should be crawlable; avoid lazy-loading above-fold images |
Responsive Design & Mobile Adaptation
Responsive design = Single HTML; CSS media queries adapt layout to screen size. Preferred for SEO: one URL, no duplicate content.
| Principle | Practice |
|---|---|
| Mobile-first | Design for mobile first; enhance for desktop |
| Fluid layout | Use %, vw, flex, grid; avoid fixed pixel widths |
| Breakpoints | Common: 320px, 768px, 1024px, 1280px; match device widths |
| Images | Responsive images (srcset, sizes); see image-optimization |
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.
