Swift concurrency review/fix: compiler errors, Sendable, isolation, remediation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Swift Concurrency Expert _Attribution: copied from @Dimillian’s `Dimillian/Skills` (2025-12-31)._ ## Overview Review and fix Swift Concurrency issues in Swift 6.2+ codebases by applying actor isolation, Sendable safety, and modern concurrency patterns with minimal behavior changes. ## Workflow ### 1. Triage the issue - Capture the exact compiler diagnostics and the offending symbol(s). - Identify the current actor context (`@MainActor`, `actor`, `nonisolated`) and whether a default actor isolation mode is enabled. - Confirm whether the code is UI-bound or intended to run off the main actor. ### 2. Apply the smallest safe fix Prefer edits that preserve existing behavior while satisfying data-race safety. Common fixes: - **UI-bound types**: annotate the type or relevant members with `@MainActor`. - **Protocol conformance on main actor types**: make the conformance isolated (e.g., `extension Foo: @MainActor SomeProtocol`). - **Global/static state**: protect with `@MainActor` or move into an actor. - **Background work**: move expensive work into a `@concurrent` async function on a `nonisolated` type or use an `actor` to guard mutable state. …

How to install
mdr add steipete/agent-scripts/swift-concurrency-expert@sha256:eaf45b1328726e35The line at the top of this page pins the label git:20260523.0a2d76c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
