Interpretation is structured for decision-making; original keeps the upstream SKILL.md unchanged.

Decide Fit First

Core job: Use when asking how to use Axiom or what skills exist, capturing console with xclog, symbolicating .ips/MetricKit/.crash crashes…
Best fit: Use it when the task has reusable inputs, steps, and validation criteria rather than a one-off answer.
Avoid forcing it: If the source lacks commands, platform support, or external-service evidence, keep those fields unknown instead of guessing.

Design Intent

Structure: The skill is organized around “Routing”, “Using Axiom Skills”, “The Rule”, “Red Flags — iOS-Specific Rationalizations”, showing how the author expects the agent to judge fit, collect context, and produce verifiable output.
Trigger evidence: Prioritize the author’s wording around when to use it, what context to collect, and what output shape to produce.
Evidence boundary: Author text states facts, repository files prove commands and paths, and Fluxly only adds fit, limits, and usage judgment.

How To Use It

Inputs: Provide target material, scope, expected result, forbidden changes, and validation method.
Invocation: Name axiom-tools directly; if the source includes slash commands, start with the command and then add task context.
Validation: Start small and check whether the result follows “Routing / Using Axiom Skills / The Rule” before expanding.

Boundaries And Review

Dependencies: It usually needs no extra API key, so start with a small validation task.
Permissions: Declared permissions include read / write; ask the agent to state file, command, and rollback boundaries before acting.
Quality bar: A useful result names the deliverable, evidence, and next action. Generic prose means the task needs tighter context.

Axiom Tools & Onboarding

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

Not on Claude Code? Where this router says "Launch some-auditor agent", read that auditor's file in this suite and follow it inline — the same procedure, needing only file search and read.

Homed in another suite: axiom-accessibility/skills/accessibility-auditor.md, axiom-concurrency/skills/concurrency-auditor.md, axiom-performance/skills/energy-auditor.md, axiom-performance/skills/memory-auditor.md, axiom-testing/skills/test-failure-analyzer.md.

Agents that need Bash — builds, tests, simulators, crash symbolication — stay Claude Code-only; there is no inline equivalent for those.

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:

Environment/Build first (axiom-build) — Fix the environment before debugging code
Architecture patterns (axiom-swiftui, axiom-data, axiom-concurrency) — These determine HOW to structure the solution
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:

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

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

Multi-Domain Questions

When a question spans multiple domains, invoke ALL relevant routers — don't stop after the first one.

Examples:

"My SwiftUI view doesn't update when SwiftData changes" → invoke both axiom-swiftui AND axiom-data
"My widget isn't showing updated data from SwiftData" → invoke both axiom-integration AND axiom-data
"My Foundation Models session freezes the UI" → invoke both axiom-ai AND axiom-concurrency
"My Core Data saves lose data from background tasks" → invoke both axiom-data AND axiom-concurrency

How to tell: If the question mentions symptoms from two different domains, or involves two different frameworks, invoke both routers. Each router has cross-domain routing guidance for common overlaps.

Backward Compatibility

Direct skill invocation still works: /skill axiom-concurrency
Commands work unchanged: /axiom:fix-build, /axiom:audit accessibility
Agents work via routing or direct command invocation

When Axiom Skills Don't Apply

Skip Axiom skills for:

Non-iOS/Swift projects (Android, web, backend)
Generic programming questions unrelated to Apple platforms
Questions about Claude Code itself (use claude-code-guide skill)

But when in doubt for iOS/Swift work: check first, decide later.

Device Hub (Xcode 27)

On Xcode 27, Device Hub — a standalone app that auto-launches on build-and-run — replaces the Simulator.app GUI and manages simulators and physical devices in one place (Xcode 26 and earlier keep Simulator.app). Every operation has an Xcode-independent CLI counterpart, so the Axiom tools and scripts are unaffected.

For the full tool map (Device Hub / devicectl / simctl / xcui vs mcpbridge, and what each costs to run), the verified subcommand matrix, the unified devicectl device capture screenshot/screen-record path (works on sim and device, Xcode 26.6+), the status-bar overrides that prep a screenshot (statusBar preset screenshot and the simctl equivalents), and the Device Hub GUI reference, see skills/device-control-ref.md.

Resources

Skills: axiom-swiftui, axiom-concurrency, axiom-data, axiom-build, axiom-performance

Axiom tools: xclog (simulator console capture, skills/xclog-ref.md), xcsym (crash symbolication for .ips, MetricKit, legacy .crash text files, and Xcode Organizer .xccrashpoint bundles, skills/xcsym-ref.md), xcui (scriptable sim UI & accessibility testing, skills/xcui-ref.md), xcprof (structured xctrace CPU & network profile analysis, skills/xcprof-ref.md)
