Build script: - Escape backslashes before quotes in YAML output - Handle Windows-style line endings in frontmatter parsing - Use dir.name (not fm.name) for display_name consistency - Warn when openai.yaml is skipped due to missing frontmatter - Compute actual skipped count from filesystem, not set size Docs: - Add Deno prerequisite - Clarify that axiom-codex/ is created by the build step - Remove unverified $skill-name invocation syntax - Add Troubleshooting section - Improve Also Available with relationship explanations - Change "Not yet supported" to "Not supported" for accuracy
Axiom
Battle-tested skills, agents, and tools for modern iOS development with AI coding assistants. Native for Claude Code, MCP for everything else.
What is Axiom?
Axiom gives AI coding assistants deep iOS development expertise — the kind that prevents data loss from bad migrations, catches memory leaks before users complain, and stops you from spending 30 minutes debugging a zombie xcodebuild process.
- 175 skills covering UI, data, concurrency, performance, networking, accessibility, and more
- 38 agents that autonomously scan for issues (memory leaks, concurrency violations, build problems)
- 12 commands for quick audits and diagnostics
- xclog — a built-in console capture tool that gives AI assistants access to simulator and device logs
Every discipline skill is TDD-tested against real developer pressure scenarios. Learn more about quality.
Installation
Claude Code (native plugin)
/plugin marketplace add CharlesWiltgen/Axiom
Then search for "axiom" in the /plugin menu and install.
MCP (VS Code, Cursor, Gemini CLI, and more)
See the MCP setup guide.
Xcode (Claude Agent / Codex)
See the Xcode integration guide.
Getting Started
Skills activate automatically based on your questions. Just ask:
"I'm getting BUILD FAILED in Xcode"
"How do I fix Swift 6 concurrency errors?"
"My app has memory leaks"
"I need to add a database column safely"
"Show me what my app is logging"
You can also use commands directly:
/axiom:console # Capture simulator console output
/axiom:fix-build # Diagnose build failures
/axiom:audit memory # Scan for memory leaks
/axiom:audit concurrency # Check for data races
/axiom:health-check # Run all relevant auditors
