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 | $0.00027 | $0.01355 |
| Opus 5.5 | $0.00011 | $0.00542 |
| Sonnet 5.5 | $0.00005 | $0.00271 |
| Haiku 4.5 | $0.00003 | $0.00136 |
Grade A, and why
core-components 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.
This is a copy
100% identical to core-components — 86 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Core Components
Design System Overview
Use components from your core library instead of raw platform components. This ensures consistent styling and behavior.
Design Tokens
NEVER hard-code values. Always use design tokens.
Spacing Tokens
// CORRECT - Use tokens
<Box padding="$4" marginBottom="$2" />
// WRONG - Hard-coded values
<Box padding={16} marginBottom={8} />
| Token | Value |
|---|---|
$1 |
4px |
$2 |
8px |
$3 |
12px |
$4 |
16px |
$6 |
24px |
$8 |
32px |
Color Tokens
// CORRECT - Semantic tokens
<Text color="$textPrimary" />
<Box backgroundColor="$backgroundSecondary" />
// WRONG - Hard-coded colors
<Text color="#333333" />
<Box backgroundColor="rgb(245, 245, 245)" />
| Semantic Token | Use For |
|---|---|
$textPrimary |
Main text |
$textSecondary |
Supporting text |
$textTertiary |
Disabled/hint text |
$primary500 |
Brand/accent color |
$statusError |
Error states |
$statusSuccess |
Success states |
Typography Tokens
<Text fontSize="$lg" fontWeight="$semibold" />
| Token | Size |
|---|---|
$xs |

$sm |
14px |
$md |
16px |
$lg |

<Text>Username</Text>
</HStack>
<VStack gap="$4" padding="$4">

<Text>Content</Text>
</VStack>

Typography with token support:
<Text fontSize="$lg" fontWeight="$semibold" color="$textPrimary">
Hello World
</Text>
Button
Interactive button with variants:
<Button
onPress={handlePress}
variant="solid"
size="md"
isLoading={loading}
isDisabled={disabled}
>
Click Me
</Button>
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.

core-components is a skill published in the GitHub repository klh/speedy-claude (11 stars, last pushed 28d ago), licensed MIT. It adds 27 tokens to every session and 1,355 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to core-components, differing in 86 lines, and is treated as a copy.
