build-optimizer

Automatically scans Xcode projects for build performance optimizations and provides quick wins with measurable time savings.

How to Use This Agent

Natural language (automatic triggering):

• "My builds are slow"
• "How can I speed up build times?"
• "Optimize my Xcode build performance"
• "Builds are taking forever"
• "Can you make my builds faster?"

Explicit command:

/axiom:optimize-build

What It Checks

1. Build Settings (HIGH) — Compilation mode, architecture settings, debug info format
2. Build Phase Scripts (HIGH) — Conditional execution, sandboxing, unnecessary scripts in Debug
3. Type Checking Performance (MEDIUM) — Slow-compiling functions, complex type inference
4. Compiler Flags (MEDIUM) — Suboptimal Swift compiler flags

Expected Results

Based on typical findings:

• 30-50% faster incremental debug builds
• 5-10 seconds saved per build from conditional scripts
• Measurable improvements in Build Timeline

Model & Tools
