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:

bash

/axiom:optimize-build

What It Does

Build Settings (HIGH) — Compilation mode, architecture settings, debug info format
Build Phase Scripts (HIGH) — Conditional execution, sandboxing, unnecessary scripts in Debug
Type Checking Performance (MEDIUM) — Slow-compiling functions, complex type inference
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
