3Use this skill as the recommend-first entrypoint for end-to-end Xcode build optimization work.

5## Non-Negotiable Rules
6 
7- Wall-clock build time (how long the developer waits) is the primary success metric. Every recommendation must state its expected impact on the developer's actual wait time.
8- Start in recommendation mode.
9- Benchmark before making changes.
10- Do not modify project files, source files, packages, or scripts without explicit developer approval.
11- Preserve the evidence trail for every recommendation.
12- Re-benchmark after approved changes and report the wall-clock delta.

14## Two-Phase Workflow
15 
16The orchestration is designed as two distinct phases separated by developer review.

18### Phase 1 -- Analyze (recommend-only)
19 
20Run this phase in agent mode because the agent needs to execute builds, run benchmark scripts, write benchmark artifacts, and generate the optimization report. However, treat Phase 1 as **recommend-only**: do not modify any project files, source files, packages, or build settings. The only files the agent creates during this phase are benchmark artifacts and the optimization plan inside `.build-benchmark/`.
