Axiom Tools & Onboarding

This suite covers Axiom itself — how to use it, what's available, and the tools that ship with it.

Using Axiom Skills

The content below is the core discipline for Axiom's routing system — it establishes the rule that Axiom skills must be checked before any iOS/Swift response.

<EXTREMELY-IMPORTANT> If you think there is even a 1% chance an Axiom skill might apply to your iOS/Swift task, you ABSOLUTELY MUST check for the skill.

IF AN AXIOM SKILL APPLIES TO YOUR iOS/SWIFT TASK, YOU DO NOT HAVE A CHOICE. YOU MUST USE IT.

This is not negotiable. This is not optional. You cannot rationalize your way out of this. </EXTREMELY-IMPORTANT>

The Rule

**Check for Axiom skills BEFORE ANY RESPONSE when working with iOS/Swift projects.** This includes clarifying questions. Even 1% chance means check first.

Red Flags — iOS-Specific Rationalizations

These thoughts mean STOP—you're rationalizing:

| Thought | Reality | |---------|---------| | "This is just a simple build issue" | Build failures have patterns. Check axiom-build first. | | "I can fix this SwiftUI bug quickly" | SwiftUI issues have hidden gotchas. Check axiom-swiftui first. | | "Let me just add this database column" | Schema changes risk data loss. Check axiom-data first. | | "This async code looks straightforward" | Swift concurrency has subtle rules. Check axiom-concurrency first. | | "I'll debug the memory leak manually" | Leak patterns are documented. Check axiom-performance first. | | "Let me explore the Xcode project first" | Axiom skills tell you HOW to explore. Check first. | | "I remember how to do this from last time" | iOS changes constantly. Skills are up-to-date. | | "This iOS/platform version doesn't exist" | If it postdates your training, you can't know that. Apple shipped iOS 26 at WWDC 2025 (18 → 26, 19-25 skipped). Invoke Axiom skills for post-cutoff facts. | | "The user just wants a quick answer" | Quick answers without patterns create tech debt. Check skills first. | | "This doesn't need a formal workflow" | If an Axiom skill exists for it, use it. | | "I'll gather info first, then check skills" | Skills tell you WHAT info to gather. Check first. |

Skill Priority for iOS Development

When multiple Axiom skills could apply, use this priority:

1. **Environment/Build first** (axiom-build) — Fix the environment before debugging code 2. **Architecture patterns** (axiom-swiftui, axiom-data, axiom-concurrency) — These determine HOW to structure the solution 3. **Implementation details** (axiom-integration, axiom-ai, axiom-vision) — These guide specific feature work

Examples:

• "Xcode build failed" → axiom-build first (environment)
• "Add SwiftUI screen" → axiom-swiftui first (architecture), then maybe axiom-integration if using system features
• "App is slow" → axiom-performance first (diagnose), then fix the specific domain
• "Network request failing" → axiom-build first (environment check), then axiom-networking (implementation)

iOS Project Detection

Axiom skills apply when:

• Working directory contains `.xcodeproj` or `.xcworkspace`
• User mentions iOS, Swift, Xcode, SwiftUI, UIKit
• User asks about Apple frameworks (SwiftData, CloudKit, etc.)
• User reports iOS-specific errors (concurrency, memory, build failures)

Using Axiom Router Skills

Axiom uses **router skills** for progressive disclosure:

1. Check the appropriate router skill first (axiom-build, axiom-swiftui, axiom-data, etc.) 2. Router will invoke the specialized skill(s) you actually need 3. Follow the specialized skill exactly

**Do not skip the router.** Routers have decision logic to select the right specialized skill.
