Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00041 | $0.00653 |
| Opus 5 | $0.00020 | $0.00327 |
| Sonnet 5 | $0.00008 | $0.00131 |
| Haiku 4.5 | $0.00004 | $0.00065 |
Grade A, and why
mobile-app-testing 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 9d 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.

Mobile App Testing
Table of Contents
Overview
Implement comprehensive testing strategies for mobile applications including unit tests, UI tests, integration tests, and performance testing.
When to Use
- Creating reliable mobile applications with test coverage
- Automating UI testing across iOS and Android
- Performance testing and optimization
- Integration testing with backend services
- Regression testing before releases
Quick Start
Minimal working example:
// Unit test with Jest
import { calculate } from "../utils/math";
describe("Math utilities", () => {
test("should add two numbers", () => {
expect(calculate.add(2, 3)).toBe(5);
});
test("should handle negative numbers", () => {
expect(calculate.add(-2, 3)).toBe(1);
});
});
// Component unit test
import React from "react";
import { render, screen } from "@testing-library/react-native";
import { UserProfile } from "../components/UserProfile";
describe("UserProfile Component", () => {
test("renders user name correctly", () => {
const mockUser = { id: "1", name: "John Doe", email: "[email protected]" };
render(<UserProfile user={mockUser} />);
expect(screen.getByText("John Doe")).toBeTruthy();
});
// ... (see reference guides for full implementation)

What ships with it
6 files 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.

mobile-app-testing is a skill published in the GitHub repository aj-geddes/useful-ai-prompts (338 stars, last pushed 6mo ago), licensed MIT. It adds 41 tokens to every session and 653 once invoked, about $0.0002 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 2026-09-03.
