## What swift-concurrency does, in the publisher's words

Expert guidance for any AI coding tool that supports the Agent Skills open format, safe concurrency, performance, and Swift 6+ migration.

Based on the comprehensive Swift Concurrency Course, distilled into actionable, concise references for agents.

This repository is packaged as a portable Agent Plugin (spec 1.0.0): compatible clients discover the skill automatically from the root plugin.json manifest and the skills/ directory. Client-specific manifests for Claude Code, Cursor, Codex, and pi are included as well, and the plugin is published in the OpenAI Plugins Directory for ChatGPT and Codex.

- Teams migrating to Swift 6 / strict concurrency who need safe defaults and quick triage.
- Developers debugging data races, isolation errors, or flaky async tests.
- Anyone wanting performance-minded concurrency patterns (actors, tasks, Sendable, async streams).
