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.

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 | $0.00055 | $0.01707 |
| Opus 5 | $0.00028 | $0.00853 |
| Sonnet 5 | $0.00011 | $0.00341 |
| Haiku 4.5 | $0.00006 | $0.00171 |
Grade A, and why
testing-perf 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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Performance & Load Testing Patterns
Focused skill for performance testing, load testing, and pytest execution optimization. Covers k6, Locust, pytest-xdist parallel execution, custom plugins, and test type classification.

k6 Quick Start
Set up a load test with thresholds and staged ramp-up:
import http from 'k6/http';
import { check, sleep } from 'k6';
export const options = {
stages: [
{ duration: '30s', target: 20 }, // Ramp up
{ duration: '1m', target: 20 }, // Steady state
{ duration: '30s', target: 0 }, // Ramp down
],
thresholds: {
http_req_duration: ['p(95)<500'], // 95th percentile under 500ms
http_req_failed: ['rate<0.01'], // Less than 1% error rate
},
};
export default function () {
const res = http.get('http://localhost:8000/api/health');
check(res, {
'status is 200': (r) => r.status === 200,
'response time < 200ms': (r) => r.timings.duration < 200,
});
sleep(1);
}

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.

testing-perf is a skill published in the GitHub repository yonatangross/orchestkit (231 stars, last pushed today), licensed MIT. It adds 55 tokens to every session and 1,707 once invoked, about $0.0003 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 2026-09-05.
