# Performance

**You MUST use this skill for ANY performance issue including memory leaks, slow execution, battery drain, or profiling.**

**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.

<!-- AXIOM_AUDITOR_INLINE_BEGIN — rewritten for Codex by scripts/build-codex.ts; do not hand-edit -->
> **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-swift-performance`, `axiom-audit-energy`, `axiom-audit-memory`.
>
> The ones that shell out — builds, tests, simulators, crash symbolication — need shell access to run.
