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.
npx agentmods add rules/sushaantu/boxento/styling-conventionsgit clone --depth 1 https://github.com/sushaantu/boxentoWhat it costs to keep this loaded
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 | $0.00000 | $0.00171 |
| Opus 5 | $0.00000 | $0.00086 |
| Sonnet 5 | $0.00000 | $0.00034 |
| Haiku 4.5 | $0.00000 | $0.00017 |
Grade A, and why
styling-conventions 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 today.
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
- Use Tailwind CSS classes exclusively for styling
- Follow utility-first CSS methodology
- Avoid creating custom CSS files unless absolutely necessary
- Use Tailwind's @apply directive for reusable styles in components
- Maintain consistent spacing and layout using Tailwind's spacing scale
- Use Tailwind's color palette for consistency
- Support dark mode with Tailwind's dark: variant
- Extract common class combinations into reusable React components
- Use CSS variables (via Tailwind) for theming when appropriate
- For complex animations, use framer-motion library with Tailwind classes
- Place responsive design variants in a consistent order (sm:, md:, lg:, xl:)
- Group related utility classes together (spacing, colors, typography)
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.

styling-conventions is a cursor rule published in the GitHub repository sushaantu/boxento (153 stars, last pushed 20d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 171 tokens. 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 2026-09-01.
