concurrency-validator

Automatically scans Swift code for Swift 6 strict concurrency violations to prevent data races.

How to Use This Agent

Natural language (automatic triggering):

"Check my code for Swift 6 concurrency issues"
"I'm getting data race warnings, can you scan for concurrency violations?"
"Review my async code for concurrency safety"
"Check if my code is ready for Swift 6 strict concurrency"

Explicit command:

bash

/axiom:audit-concurrency

What It Checks

Missing @MainActor (CRITICAL) — UIViewController, UIView, ObservableObject without @MainActor
Unsafe Task Captures (HIGH) — Task { self.property } without [weak self]
Sendable Violations (HIGH) — Non-Sendable types passed across actor boundaries
Actor Isolation Problems (MEDIUM) — Accessing actor properties without await
Thread Confinement Violations (HIGH) — @MainActor properties accessed from background
