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 | $0.00027 | $0.08601 |
| Opus 5 | $0.00014 | $0.04300 |
| Sonnet 5 | $0.00005 | $0.01720 |
| Haiku 4.5 | $0.00003 | $0.00860 |
Grade A, and why
react 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 2d 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.

Requirements
- Always use destructured props in function parameters
- Define TypeScript types inline with the destructured props
- Avoid creating separate interfaces for component props
- Avoid non-destructured props that require additional destructuring inside the component
- Use available UI components from the component library
- Use CSS variables from globals.css for consistent theming
- Use Tailwind v4 syntax (see Tailwind v4 Syntax)
- DO NOT add icon margin in Button, DropdownMenuItem: use gap-2 instead
- Use
useEffectEventto extract non-reactive logic from Effects (see Separating Events from Effects) - NEVER suppress the dependency linter with
eslint-disable- useuseEffectEventinstead - Use custom breakpoint syntax for responsive design (see App-Specific Rules)
Tailwind v4 Syntax
- Inline opacity: Use
/for opacity (bg-black/50 text-white/80)- v3:
bg-black bg-opacity-50 text-white text-opacity-80 - Removed:
bg-opacity-*,text-opacity-*,border-opacity-*
- v3:
- Renamed utilities:
shadow-sm→shadow-xs,rounded-sm→rounded-xs,blur-sm→blur-xs - CSS variables: Use parentheses
bg-(--brand-color)instead of bracketsbg-[--brand-color] - Important modifier: Exclamation mark at the end (
size-5!) instead of beginning (!size-5) - Descendant selectors: Use
**:for all descendants (replaces[&_*]:) and*:for direct children (replaces[&>*]:)- All descendants:
**:px-4instead of[&_*]:px-4 - Direct children:
*:px-4instead of[&>*]:px-4 - Element filtering:
*:[a]:underlineinstead of[&>a]:underline,**:[a]:underlineinstead of[&_a]:underline - Data attributes:
*:data-[slot=field-label]:flex-autoinstead of*:[[data-slot=field-label]]:flex-auto. Keep[[data-...]]if there are other selectors. - Context-aware (in-):
in-data-[slot=tooltip-content]:text-backgroundinstead of[[data-slot=tooltip-content]_&]:text-background
- All descendants:
- Composable variants: Chain variants together (
group-has-data-selected:opacity-100,data-highlighted:ring-2) - Canonical classes: Always prefer built-in utilities over arbitrary values (e.g.,
w-fullinstead ofw-[100%],translate-x-fullinstead oftranslate-x-[100%]) - Default changes: Border color now
currentColor(wasgray-200), ring width now 1px (was 3px)
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.

react is a skill published in the GitHub repository udecode/plate-playground-template (240 stars, last pushed 12d ago), licensed MIT. It adds 27 tokens to every session and 8,601 once invoked, about $0.0001 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 2026-08-30.
