swift-testing is a skill for Claude Code from IGTA-Tech/claude-skills-research. It costs 45 tokens per session (4,859 once invoked), scanned A, original, no licence file.

A guide to writing unit tests in Swift with Apple’s Swift Testing framework, including tests for asynchronous code. Unit tests check small parts of a program in isolation.

In plain words
What is it for?
Use it to create test suites, test async code, migrate from XCTest, and design Swift code for easier testing.
Why use it?
It helps replace or improve XCTest tests, make tests run without a simulator, and expose code that is difficult to test safely.

Token cost

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.

Security

Grade A, and why

swift-testing scanned grade A with 1 finding 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 6d 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.

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.
