Axiom Tools

This is the meta-skill that teaches Claude how to route iOS and Swift questions to the right specialized Axiom skills. It includes three command-line tools that ship with Axiom: xclog for capturing simulator console output, xcsym for symbolicating crashes from .ips files and other formats, and xcui for driving simulator UI and accessibility testing. The routing discipline is aggressive by design. It forces Claude to check for applicable skills before responding to any iOS or Swift question, even clarifying questions. The source includes a table of rationalizations developers use to skip the lookup, which tells you this addresses a real behavioral problem with LLM routing.

Axiom Tools & Onboarding

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

Bundled tools on Claude Code: if command -v <tool> finds nothing (hooks off or --bare), use <plugin-root>/tools/<tool> in place of the bare name; <plugin-root> is two levels above this skill's Base directory for this skill: path.

Auditors are skills here. Where this router says "Launch some-auditor agent", invoke the matching Codex skill instead — same procedure, no Claude Code agent required.

Available: axiom-analyze-test-failures, axiom-audit-accessibility, axiom-audit-concurrency, axiom-audit-energy, axiom-audit-memory.

The ones that shell out — builds, tests, simulators, crash symbolication — need shell access to run.
