Performance

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

Not on Claude Code? Where this router says "Launch some-auditor agent", read that auditor's file in this suite and follow it inline — the same procedure, needing only file search and read.

Available here: skills/energy-auditor.md, skills/memory-auditor.md, skills/swift-performance-analyzer.md.

Agents that need Bash — builds, tests, simulators, crash symbolication — stay Claude Code-only; there is no inline equivalent for those.

When to Use

Use this router when:

  • App feels slow or laggy
  • Memory usage grows over time
  • Battery drains quickly
  • Device gets hot during use
  • High energy usage in Battery Settings
  • Diagnosing performance with Instruments
  • Memory leaks or retain cycles
  • App crashes with memory warnings

Decision Tree

  1. Memory climbing + UI stutter/jank? → memory-debugging FIRST (memory pressure causes GC pauses that drop frames), then performance-profiling if memory is fixed but stutter remains
  2. Memory leak (Swift)? → memory-debugging
  3. Memory leak (Objective-C blocks)? → objc-block-retain-cycles
  4. App hang/freeze — is UI completely unresponsive (can't tap, no feedback)?
    • YES → hang-diagnostics (busy vs blocked diagnosis)
    • NO, just slow → performance-profiling (Time Profiler)
    • First launch only? → Also check for synchronous I/O or lazy initialization in hang-diagnostics
    • Multiple grouped hang reports from Sentry/ASC (corpus, not single file)? → axiom-shipping (skills/production-triage.md) + triage-analyzer
  5. Slowdown when multiple async operations complete at once? → Cross-route to axiom-concurrency (callback contention, not profiling)
  6. Slow app launch / slow first frame / launch regression / slow after push tap? → app-launch
  7. Battery drain (know the symptom)? → energy-diag
  8. Battery drain (need API reference)? → energy-ref
  9. Battery drain (general)? → energy
  10. MetricKit setup/parsing? → metrickit-ref 10a. Metrics split by app state (per-tab hitch rate, experiment arms) or StateReporting? → metrickit-ref (Part 1) 10b. Profiling agentic/LLM features (Foundation Models instrument, token metrics)? → performance-profiling, then axiom-ai 10c. Building a crash reporter extension (process crashes at crash time)? → metrickit-ref (Part 10)
  11. Profile with GUI (Instruments)? → performance-profiling
  12. Profile with CLI (xctrace)? → xctrace-ref
  13. Run automated profile now? → performance-profiler agent
  14. General slow/lag? → performance-profiling 14a. Slow GRDB/SQLite queries (EXPLAIN QUERY PLAN, index design, cursors)? → See axiom-data (skills/grdb-performance.md)
  15. Want proactive memory leak scan? → memory-auditor (Agent)
  16. Want energy anti-pattern scan? → energy-auditor (Agent)
  17. Want Swift performance audit (ARC, generics, collections)? → swift-performance-analyzer (Agent)
  18. Need to inspect variable/thread state at runtime? → See axiom-build (skills/lldb.md)
  19. Need exact LLDB command syntax? → See axiom-build (skills/lldb-ref.md)
  20. Timer stops during scrolling? → timer-patterns (RunLoop mode)
  21. EXC_BAD_INSTRUCTION crash with DispatchSourceTimer? → timer-patterns (4 crash patterns)
  22. Choosing between Timer, DispatchSourceTimer, Combine timer, async timer? → timer-patterns
  23. Need timer API syntax/lifecycle? → timer-patterns-ref
  24. Code review for outdated Swift patterns? → swift-modern
  25. Claude generating legacy APIs (DateFormatter, CGFloat, DispatchQueue)? → swift-modern
  26. Need to see runtime console output before profiling? → axiom-tools (skills/xclog-ref.md) or /axiom:console
  27. Have an .ips, MetricKit, or legacy .crash text file to symbolicate/triage? → axiom-tools (skills/xcsym-ref.md) or /axiom:analyze-crash

Anti-Rationalization

ThoughtReality
"I know it's a memory leak, let me find it"Memory leaks have 6 patterns. memory-debugging diagnoses the right one in 15 min vs 2 hours.
"I'll just run Time Profiler"Wrong Instruments template wastes time. performance-profiling selects the right tool first.
"Battery drain is probably the network layer"Energy issues span 8 subsystems. energy skill diagnoses the actual cause.
"App feels slow, I'll optimize later"Performance issues compound. Profiling now saves exponentially more time later.
"It's just a UI freeze, probably a slow API call"Freezes have busy vs blocked causes. hang-diagnostics has a decision tree for both.
"Memory is climbing AND scrolling stutters — two separate bugs"Memory pressure causes GC pauses that drop frames. Fix the leak first, then re-check scroll performance.
"It only freezes on first launch, must be loading something"First-launch hangs have 3 patterns: synchronous I/O, lazy initialization, main thread contention. hang-diagnostics diagnoses which.
"Launch feels slow — I'll trim some startup code"Launch has 3 phases (pre-main / main→first frame / extended) and a watchdog. app-launch tells you which phase to profile, with measurement hygiene so the number means something.
