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 | $0.00755 | $0.00755 |
| Opus 5.5 | $0.00302 | $0.00302 |
| Sonnet 5.5 | $0.00151 | $0.00151 |
| Haiku 4.5 | $0.00076 | $0.00076 |
Grade A, and why
presets.dev tailwind.instructions.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tailwind CSS Copilot Instructions: CSS-First Tokens and Accessible UI
Path-specific Copilot instructions for Tailwind CSS. They apply through applyTo and leave .github/copilot-instructions.md in place.
Updated for Tailwind CSS 4.3.5, Nov 2026
Do not upgrade dependencies or the framework version unless the task asks.
Project shape
Read the stylesheet entry and the package version before adding utilities. v4 projects use @import "tailwindcss" and @theme for tokens. v3 projects use the config file and @tailwind directives. Match the one that is installed.
Put design tokens in the theme the project already has. A one-off hex in a class is a last resort. Name the token after the role (color-surface), not the raw value.
Class names
Write class names the compiler can see. className="px-4 py-2" is visible. className={`px-${n}`} is not, and it will not generate CSS. If you need a dynamic value, map a finite set of full class strings, or set a CSS variable.
Do not fight the cascade with a long string of conflicting utilities. Remove the one that lost. Use the project's component or cva helper if one exists, instead of copying a 40-class string between files.
Layout and accessibility
Build responsive layouts with the breakpoints the project uses. Start from the small screen. Do not hide focus outlines. A control that is only an icon needs an accessible name.
Contrast comes from the theme tokens. Do not put gray text on a gray surface because it looks quiet. Respect motion-reduce when you add animation. Hit targets stay large enough to tap.
Errors and states
Style the states the component can be in: empty, loading, error, disabled. Disabled is disabled: plus a real disabled attribute, not only a faded class. Error text is not color alone. Add the words.
Performance
The production build scans source files. Do not safelist the entire color palette to make dynamic classes work. Fix the class so it is static. Do not import Tailwind into a file the bundler already processes twice.
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.
