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 | $0.00037 | $0.04341 |
| Opus 5.5 | $0.00015 | $0.01736 |
| Sonnet 5.5 | $0.00007 | $0.00868 |
| Haiku 4.5 | $0.00004 | $0.00434 |
Grade A, and why
gluestack-ui-v4:validation 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 1mo 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.

Gluestack UI v4 - Validation & Anti-Patterns
This sub-skill focuses on validating implementations, identifying anti-patterns, and ensuring code quality for gluestack-ui v4.
Validation Checklist
When reviewing code, check for:
Component Usage
- Component usage verified against official v4 docs at
https://v4.gluestack.io/ui/docs/components/${componentName}/ - All React Native primitives replaced with Gluestack components
- Components imported from local
@/components/ui/directory - GluestackUIProvider wraps the app
Component Props vs className
- Component props used instead of className when available:
- VStack/HStack use
spaceprop instead ofgap-*className - Button uses
variantandsizeprops instead of className - Heading/Text use
sizeprop instead oftext-*className - Heading/Text use
boldprop instead offont-boldclassName - Other component props used where applicable
- VStack/HStack use
Styling
- CRITICAL: All colors use ONLY semantic tokens - NO exceptions:
- No
typography-*tokens (usetext-foreground,text-muted-foreground) - No
neutral-*tokens (use semantic equivalents) - No
gray-*orslate-*tokens (use semantic equivalents) - No numbered colors:
red-500,blue-600,green-400 - No arbitrary values:
[#3b82f6],[#DC2626] - No opacity utilities (use alpha values:
/70,/90)
- No
- All spacing values use the standard scale (no arbitrary values)
- No inline styles where className can be used
- Dark mode support using
dark:prefix (semantic tokens ensure compatibility) - Variants defined using
tvawhen needed - className properly merged in custom components
Compound Components
- Compound components used correctly:
- InputIcon always wrapped in InputSlot (CRITICAL)
- ButtonText used for all button text content
- FormControl sub-components used (FormControlLabel, FormControlError, etc.)
- Card sub-components used (CardHeader, CardBody, CardFooter)
- Checkbox sub-components used (CheckboxIndicator, CheckboxIcon, CheckboxLabel)
- All other component sub-components as per official docs
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.
- 1mo ago First seen · 562 lines · 37 tokens per session scan A 07e9df73e068
gluestack-ui-v4:validation is a skill published in the GitHub repository gluestack/agent-skills (1 stars, last pushed 3mo ago), licensed MIT. It adds 37 tokens to every session and 4,341 once invoked, about $0.0001 per session on Opus 5.5. 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.
