Use this agent when the user mentions accessibility checking, App Store submission, code review, or WCAG compliance. Automatically runs comprehensive accessibility audit to detect VoiceOver issues, Dynamic Type violations, color contrast failures, and WCAG compliance problems - prevents App Store rejections and ensures usability for users with disabilities. <example> user: "Can you check my app for accessibility issues?" assistant: [Launches accessibility-auditor agent] </example> <example> user: "I need to submit to the App Store soon, can you review accessibility?" assistant: [Launches accessibility-auditor agent] </example> <example> user: "Review my code for accessibility compliance" assistant: [Launches accessibility-auditor agent] </example> <example> user: "Check if my UI follows WCAG guidelines" assistant: [Launches accessibility-auditor agent] </example> <example> user: "I just added new UI, can you scan for accessibility problems?" assistant: [Launches accessibility-auditor agent] </example> Explicit command: Users can also invoke this agent directly with `/axiom:audit accessibility`

Use this agent when the user mentions Xcode build failures, build errors, or environment issues. Automatically diagnoses and fixes Xcode build failures using environment-first diagnostics - saves 30+ minutes by checking zombie processes, Derived Data, SPM cache, and simulator state before code investigation. <example> user: "My build is failing with BUILD FAILED but no error details" assistant: [Automatically launches build-fixer agent] </example> <example> user: "Xcode says 'No such module' after I updated packages" assistant: [Launches build-fixer agent] </example> <example> user: "Tests passed yesterday but now they're failing and I haven't changed anything" assistant: [Launches build-fixer agent] </example> <example> user: "My app builds but it's running old code" assistant: [Launches build-fixer agent] </example> <example> user: "Getting 'Unable to boot simulator' error" assistant: [Launches build-fixer agent] </example> <example> user: "Build sometimes succeeds, sometimes fails" assistant: [Launches build-fixer agent] </example> Explicit command: Users can also invoke this agent directly with `/axiom:fix-build`

Use this agent when the user mentions slow builds, build performance, or build time optimization. Automatically scans Xcode projects for build performance optimizations - identifies slow type checking, expensive build phase scripts, suboptimal build settings, and parallelization opportunities to reduce build times by 30-50%. <example> user: "My builds are taking forever, can you help optimize?" assistant: [Automatically launches build-optimizer agent] </example> <example> user: "Incremental builds are slow, what can I do?" assistant: [Launches build-optimizer agent] </example> <example> user: "How can I speed up my Xcode build times?" assistant: [Launches build-optimizer agent] </example> <example> user: "Build time increased after adding new dependencies" assistant: [Launches build-optimizer agent] </example> Explicit command: Users can also invoke this agent directly with `/axiom:optimize-build`

Use this agent when the user mentions Codable review, JSON encoding/decoding issues, data serialization audit, or modernizing legacy code. Automatically scans Swift/Objective-C for Codable anti-patterns (manual JSON building, try? swallowing errors, JSONSerialization usage) and date handling issues - prevents silent data loss and production bugs. <example> user: "Can you check my Codable code for issues?" assistant: [Launches codable-auditor agent] </example> <example> user: "Review my JSON encoding/decoding for best practices" assistant: [Launches codable-auditor agent] </example> <example> user: "Audit my code for proper Codable usage" assistant: [Launches codable-auditor agent] </example> <example> user: "Check for JSONSerialization that should use Codable" assistant: [Launches codable-auditor agent] </example> <example> user: "Scan for try? decoder issues before release" assistant: [Launches codable-auditor agent] </example> Explicit command: Users can also invoke this agent directly with `/axiom:audit codable`

Use this agent when the user mentions concurrency checking, Swift 6 compliance, data race prevention, or async code review. Automatically scans Swift code for Swift 6 strict concurrency violations - detects unsafe Task captures, missing @MainActor, Sendable violations, and actor isolation problems to prevent data races. <example> user: "Can you check my code for Swift 6 concurrency issues?" assistant: [Launches concurrency-auditor agent] </example> <example> user: "I'm getting data race warnings, can you scan for concurrency violations?" assistant: [Launches concurrency-auditor agent] </example> <example> user: "Review my async code for concurrency safety" assistant: [Launches concurrency-auditor agent] </example> <example> user: "Check if my code is ready for Swift 6 strict concurrency" assistant: [Launches concurrency-auditor agent] </example> <example> user: "I just added async/await code, can you validate it?" assistant: [Launches concurrency-auditor agent] </example> Explicit command: Users can also invoke this agent directly with `/axiom:audit concurrency`

Use when encountering "Unable to simultaneously satisfy constraints" errors, constraint conflicts, ambiguous layout warnings, or views positioned incorrectly - systematic debugging workflow for Auto Layout issues in iOS

Reference — AVFoundation audio APIs, AVAudioSession categories/modes, AVAudioEngine pipelines, bit-perfect DAC output, iOS 26+ spatial audio capture, ASAF/APAC, Audio Mix with Cinematic framework

Use when implementing widgets, Live Activities, Control Center controls, or app extensions - comprehensive API reference for WidgetKit, ActivityKit, App Groups, and extension lifecycle for iOS 14+

Use when app feels slow, memory grows, battery drains, or diagnosing ANY performance issue. Covers memory leaks, profiling, Instruments workflows, retain cycles, performance optimization.

Use when writing ANY test, debugging flaky tests, making tests faster, or asking about Swift Testing vs XCTest. Covers unit tests, UI tests, fast tests without simulator, async testing, test architecture.
