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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What 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 5.1 | $0.00029 | $0.01446 |
| Opus 5 | $0.00015 | $0.00723 |
| Sonnet 5 | $0.00006 | $0.00289 |
| Haiku 4.5 | $0.00003 | $0.00145 |
Grade A, and why
klh-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 8d 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.

Core Components
Part of klh/skills — personal agent skills by Klaus L. Hougesen. Install:
npx skills add klh/skills --skill klh-core-components
Overview
Use components from your core library instead of raw platform components. This ensures consistent styling and behavior.
When to Use
- When building UI with the core component library
- When using design tokens
- When working with the component library
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 |
12px |
$sm |
14px |
$md |
16px |
$lg |
18px |
$xl |
20px |
$2xl |
24px |
Core Components
Box
Base layout component with token support:
<Box padding="$4" backgroundColor="$backgroundPrimary" borderRadius="$lg">
{children}
</Box>
HStack / VStack
Horizontal and vertical flex layouts:
<HStack gap="$3" alignItems="center">
<Icon name="user" />
<Text>Username</Text>
</HStack>
<VStack gap="$4" padding="$4">
<Heading>Title</Heading>
<Text>Content</Text>
</VStack>
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 8d ago First seen · 270 lines · 29 tokens per session scan A 9aaf0b50a918
klh-core-components is a skill published in the GitHub repository klh/speedy-claude (11 stars, last pushed 2d ago), licensed MIT. It adds 29 tokens to every session and 1,446 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 2026-09-04.
