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 | $0.00011 | $0.00376 |
| Opus 5.5 | $0.00004 | $0.00150 |
| Sonnet 5.5 | $0.00002 | $0.00075 |
| Haiku 4.5 | $0.00001 | $0.00038 |
Grade A, and why
security 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.
What it actually says
Security & Error Handling
Sicherheit
- Input Validation für alle User-Eingaben
- XSS Prevention — keine direkte DOM-Manipulation mit User-Daten
- CSRF Protection via
X-Requested-WithHeader - Rate Limiting für alle API Calls
- Secure Storage — keine sensitiven Daten im Klartext in localStorage
- OTP/Magic-Link: Single-Use Tokens, Token Expiry prüfen, Rate Limiting
Error Handling (Pflicht-Pattern)
try {
const result = await apiCall();
return result;
} catch (error) {
console.error('API Error:', error);
showError('Failed to load data. Please try again.');
return defaultValue;
}
- IMMER try/catch für async Operations
- IMMER user-freundliche Error Messages (lokalisiert via
$translations) - IMMER Fallback Values
- Error Boundaries für kritische Komponenten

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.

security is a cursor rule published in the GitHub repository chooomedia/keymoji (2 stars, last pushed 3mo ago), licensed MIT. It adds 11 tokens to every session and 376 once invoked, about $0.0000 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.
