swift-actor-persistence is a skill for Claude Code from Nmor/the-claude-council. It costs 29 tokens per session (9,731 once invoked), scanned B, original, no licence file.

A Swift data-storage pattern that uses actors to protect shared data, with a memory cache and file-backed storage.

In plain words
What is it for?
It is for building Swift persistence layers that cache data in memory and save it to files while keeping concurrent access safe.
Why use it?
It helps prevent data races, which happen when multiple parts of a program access and change the same data at the same time.

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 B, and why

swift-actor-persistence scanned grade B with 2 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 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.

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

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 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.
