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 | $0.00048 | $0.02244 |
| Opus 5.5 | $0.00019 | $0.00898 |
| Sonnet 5.5 | $0.00010 | $0.00449 |
| Haiku 4.5 | $0.00005 | $0.00224 |
Grade A, and why
implementing-command-palettes 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 27d 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.

Implementing Command Palettes
Overview
Command palettes (Cmd+K / Ctrl+K) need precise keyboard navigation, scroll behavior, and stable references to avoid re-render loops. This skill covers the mechanical patterns that make command palettes feel responsive.
When to Use
- Building a Cmd+K command palette in React
- Implementing arrow key navigation with visual selection
- Keeping selected items visible during keyboard navigation
- Filtering commands by label text AND keyboard shortcuts
- Experiencing infinite re-renders when commands update
Quick Reference
| Feature | Implementation |
|---|---|
| Arrow navigation | Track selectedIndex, clamp with Math.min/max |
| Keep in view | scrollIntoView({ block: 'nearest', behavior: 'smooth' }) |
| Shortcut matching | Strip spaces from shortcuts, match against query |
| Stable icons | Define icon elements outside component |
| Stable handlers | useCallback + noop constant for disabled states |
Keyboard Navigation
Index Management
const [selectedIndex, setSelectedIndex] = useState(0);
useEffect(() => {
if (!isOpen) return;
const handleKeyDown = (e: KeyboardEvent) => {
switch (e.key) {
case 'ArrowDown':
e.preventDefault();
// Clamp to last item
setSelectedIndex((prev) => Math.min(prev + 1, filteredItems.length - 1));
break;
case 'ArrowUp':
e.preventDefault();
// Clamp to first item
setSelectedIndex((prev) => Math.max(prev - 1, 0));
break;
case 'Enter':
e.preventDefault();
if (filteredItems[selectedIndex]) {
executeCommand(filteredItems[selectedIndex]);
close();
}
break;
case 'Escape':
e.preventDefault();
close();
break;
}
};
window.addEventListener('keydown', handleKeyDown);
return () => window.removeEventListener('keydown', handleKeyDown);
}, [isOpen, filteredItems, selectedIndex, close]);
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.

implementing-command-palettes is a skill published in the GitHub repository AgentWorkforce/relay (885 stars, last pushed yesterday), licensed Apache-2.0. It adds 48 tokens to every session and 2,244 once invoked, about $0.0002 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 2026-08-30.
