principles-ios-swift-concurrency

principles-ios-swift-concurrency is a cursor rule for Cursor from rwking/wellness_planner. It costs 436 tokens per session, scanned A, original, no licence file.

Rules for writing asynchronous Swift code and safely managing shared state. Asynchronous code lets work continue without blocking the app, while shared state is data used by multiple tasks or threads.

In plain words
What is it for?
They are used when writing async Swift code, updating the interface from background work, or coordinating shared data. They guide safer handling of concurrent tasks.
Why use it?
They help prevent data races and crashes caused by unsafe timing or UI updates. This is especially important when several operations run at once.

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

principles-ios-swift-concurrency 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 8d 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 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.
