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 | $0.00157 | $0.01547 |
| Opus 5 | $0.00078 | $0.00773 |
| Sonnet 5 | $0.00031 | $0.00309 |
| Haiku 4.5 | $0.00016 | $0.00155 |
Grade A, and why
responsive 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Responsive
Make the target work correctly at every screen size, then prove it. This is a mechanical discipline with a pass/fail gate, not a matter of taste — a layout either survives 320px and 400% zoom or it does not.
Responsive is not "it has breakpoints." A page with md: and lg: variants everywhere can still fail every gate below. What counts is measured behavior at real widths.
The gate
The work is done when all seven hold on every surface in scope. Report each one explicitly; never claim "responsive" without walking this list.
- No horizontal scroll at any width from 320px upward. Not hidden — absent.
- Content reflows at 320px with nothing lost or unreachable (WCAG 1.4.10). Two-dimensional content — data tables, maps, diagrams, code — may scroll inside its own container.
- Usable at 400% zoom on a 1280px viewport, which is the same 320 CSS px reflow requirement reached the other way. Test both; they expose different bugs.
- Every interactive target is at least 24×24 CSS px (WCAG 2.2 AA, SC 2.5.8), or has 24px of clear spacing around it. Primary touch actions get 44×44.
- Body text is at least 16px on mobile. Below that, iOS Safari zooms the whole page when a field takes focus.
- No fixed heights on anything containing text. Text grows with translation, user font settings, and long content.
- No content under the notch, home indicator, or browser chrome on devices that have them.
A gate item you could not verify is reported as unverified, never as passed.
Procedure
1. Scope and map
Name the surfaces in scope. If the user said "the whole app," list the routes and confirm the list rather than sweeping silently — a full app sweep is many surfaces, and they should know what you are about to touch.
For each surface, note which of its regions are structural (page shell, navigation, main grid) and which are components that get reused in different-sized slots. Structural regions belong to media queries; reusable components belong to container queries. Getting this split right prevents most of the churn.
What ships with it
4 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.

responsive is a skill published in the GitHub repository silvioventre/lovable-skills (2 stars, last pushed 15d ago), licensed MIT. It adds 157 tokens to every session and 1,547 once invoked, about $0.0008 per session on Opus 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 2026-08-31.
