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 | $0.00027 | $0.00310 |
| Opus 5 | $0.00014 | $0.00155 |
| Sonnet 5 | $0.00005 | $0.00062 |
| Haiku 4.5 | $0.00003 | $0.00031 |
Grade A, and why
iOS 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 4d 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
Purpose
Test iOS apps at the right level — fast unit tests for logic, UI tests for critical flows.
Checklist
- Unit tests (XCTest): test view models, networking layer, data transformation logic. Fast — no UI dependency.
- UI tests (XCUITest): test critical user journeys (login, purchase, settings navigation). Slow — use sparingly.
- Snapshot tests: use
swift-snapshot-testingor equivalent for view rendering. Cover default, empty, and error states. - Performance baselines: set
measure()blocks for critical code paths (data parsing, image processing, database queries). - Test independence: each test sets up its own state and tears down after. No shared mutable state between tests.
- CI integration: tests run on every PR. UI tests run on a physical device or simulator matrix covering target OS versions.
Expected output
A test suite where unit tests cover business logic, snapshot tests cover UI rendering, and UI tests cover only critical user journeys.
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.

iOS Testing is a skill published in the GitHub repository niels-emmer/myace (1 stars, last pushed yesterday), licensed MIT. It adds 27 tokens to every session and 310 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 2026-09-03.
