cryptotokenkit

cryptotokenkit is a skill for Claude Code from dpearson2699/swift-ios-skills. It costs 86 tokens per session (4,340 once invoked), scanned A, original, no licence file.

A guide to using Apple's CryptoTokenKit to work with security tokens and smart cards. These are physical devices or cards that store cryptographic keys and perform secure operations.

In plain words
What is it for?
Use it to build token-driver extensions, connect to smart-card slots, support NFC smart cards, register cards, and access keys stored on them.
Why use it?
It helps an app communicate with card readers and token-backed keys without implementing the low-level token handling itself.

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

cryptotokenkit 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 1mo 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.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

sudo -u _securityagent /Applications/TokenHost.app/Contents/MacOS/TokenHost

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What ships with it

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.
