Battle-tested skills, agents, and tools for modern Apple platform development with AI coding assistants. Native for Claude Code, MCP for everything else.
Axiom gives AI coding assistants deep Apple platform 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.
/plugin marketplace add CharlesWiltgen/Axiom
Then search for "axiom" in the /plugin menu and install.
See the MCP setup guide.
See the Xcode integration guide.
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
