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 | $0.00034 | $0.00237 |
| Opus 5 | $0.00017 | $0.00118 |
| Sonnet 5 | $0.00007 | $0.00047 |
| Haiku 4.5 | $0.00003 | $0.00024 |
Grade A, and why
mobile-ux-responsive-navigation-notes 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.
What it actually says
Mobile UX + responsive navigation notes
Sources reviewed / adapted
cline/skills— reviewed README andfrontend-designskill for production-grade frontend polish and anti-generic design guidance.VoltAgent/awesome-agent-skills— reviewed curated skill quality standards and security notice; used the principle of selecting/adapting only relevant guidance, not importing whole repositories.travisvn/awesome-claude-skills— reviewed references to frontend/design skills and the idea of lightweight contextual skills.
Applied principles
- Prefer a focused project-local skill over copying unrelated repositories.
- Keep the skill scoped to the actual task: mobile-only responsive navigation for HTML/CSS/Vanilla JS.
- Prioritize accessibility state, touch targets, reduced motion, no overflow, and theme preservation.
- Avoid generic/mobile-slop design: use restrained, cohesive, premium surfaces and purposeful spacing.
- Keep desktop layout untouched by placing visual changes in mobile media queries.
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.
