Axiom Tools
Route iOS and Swift agent work through Axiom’s xclog, xcsym, xcui, and xcprof tools for console capture, crash symbolication, simulator UI checks, and trace profiling.
Overview
axiom-tools is an agent skill most often used in Ship (also Build, Operate) that routes iOS and Swift tasks to Axiom’s console, symbolication, UI, and profiling tools.
Install
npx skills add https://github.com/charleswiltgen/axiom --skill axiom-toolsWhat is this skill?
- Routing table maps questions to getting-started, xclog, xcsym, xcui, and xcprof reference docs
- xclog captures console output from iOS runs
- xcsym symbolicates .ips, MetricKit, and .crash reports
- xcui drives and validates simulator UI and accessibility scripts
- xcprof analyzes xctrace CPU and network profiles
- 5-tool routing table: getting-started, xclog, xcsym, xcui, xcprof

What problem does it solve?
You are debugging or profiling an iOS app with your agent but get generic Swift advice instead of the right Axiom command or reference doc.
Who is it for?
Solo builders using Claude Code or similar agents on Swift/iOS code who already use or are adopting the Axiom toolchain.
Skip if: Teams building only web or Android apps with no iOS surface, or anyone who will ignore the mandatory Axiom skill check for Swift tasks.
When should I use this skill?
Asking how to use Axiom, what skills exist, capturing console with xclog, symbolicating crashes with xcsym, driving simulator UI with xcui, or analyzing traces with xcprof.
What do I get? / Deliverables
After routing, the agent reads the correct Axiom skill reference and applies xclog, xcsym, xcui, or xcprof workflows for your concrete artifact or question.
- Correct Axiom reference doc path for the task
- Actionable CLI or workflow steps per xclog/xcsym/xcui/xcprof
Recommended Skills
Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Canonical shelf is ship/testing because Axiom tools primarily support debugging crashes, validating simulator UI, and analyzing performance traces after or during iOS builds. Testing subphase fits simulator validation, crash triage, and profiling workflows that unblock QA before release.
Where it fits
Wire agent-driven xcui checks into your CI simulator smoke tests before merging Swift UI changes.
Symbolicate a TestFlight .ips crash and validate the fix with xclog replay on the failing build.
Run xcprof on a hung network call surfaced during release regression.
Triage production MetricKit reports when users report crashes after launch.
How it compares
Use as a routing layer for procedural Axiom CLIs—not as a substitute for Apple’s Instruments docs or unfocused chat debugging.
Common Questions / FAQ
Who is axiom-tools for?
Indie and solo iOS developers who want agents to follow Axiom’s documented tools for logs, crashes, UI checks, and traces instead of improvising.
When should I use axiom-tools?
Use it when you ask how to use Axiom, what skills exist, how to capture console output, symbolicate crashes, script simulator accessibility, or analyze xctrace profiles—typically during build integrations and ship testing, and again in operate when production crashes arrive.
Is axiom-tools safe to install?
Review the Security Audits panel on this Prism page for install counts, license (MIT), and any published audit results before adding it to your agent workflow.

# Axiom Tools & Onboarding This suite covers Axiom itself — how to use it, what's available, and the tools that ship with it. ## Routing | Question | Read | |----------|------| | "How do I use Axiom?" / "What skills are available?" | [skills/getting-started.md](skills/getting-started.md) | | "How do I capture console output?" / "What is xclog?" | [skills/xclog-ref.md](skills/xclog-ref.md) | | "How do I symbolicate a crash?" / "What is xcsym?" / "Why is my crash unsymbolicated?" | [skills/xcsym-ref.md](skills/xcsym-ref.md) | | "How do I drive/validate the sim UI?" / "What is xcui?" / "How do I script accessibility checks?" | [skills/xcui-ref.md](skills/xcui-ref.md) | | "How do I analyze a trace / CPU or network profile?" / "What is xcprof?" / "Why does the profiler report no findings?" | [skills/xcprof-ref.md](skills/xcprof-ref.md) | ## 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 (im
