3: description: |
4:   Optimize build times and artifact sizes for any project.
5:   Analyzes build process and applies performance improvements.
6: 
7:   Use when: slow build, optimize build, faster compile, build cache
8: ---
9: 
10: # Build Optimizer v3.1.0
11: 
12: Reduce build times by up to 80% with intelligent optimization.
13: 
14: ## Features
15: 
16: - Build time analysis
17: - Dependency caching
18: - Parallel compilation
19: - Artifact compression
20: 
21: ## Architecture
22: 
23: ```
24: build-optimizer/
25: ├── SKILL.md
26: └── scripts/
27:     └── build_optimizer.py   # Core optimizer implementation
28: ```
29: 
30: ## Usage
31: 
32: ```bash
33: /build-optimizer analyze
34: /build-optimizer optimize --aggressive
35: /build-optimizer benchmark before after
36: ```
37: 
38: ## Quick Start
39: 
40: **To optimize your build, simply run:**
41: 
42: ```python
43: from scripts.build_optimizer import optimize_build
44: 
45: # Run build optimization
46: optimizer = optimize_build("./my-project")
47: ```
48: 
49: **That's it!** The `optimize_build()` function handles everything automatically.
50: 
51: ## Core Functions
52: 
53: ### `optimize_build(project_dir)`
54: 
55: Main function for build optimization:
56: 
57: ```python
58: from scripts.build_optimizer import optimize_build, BuildOptimizer
59: 
60: # Simple usage
61: optimizer = optimize_build(".")
62: 
63: # Advanced usage
64: optimizer = BuildOptimizer("./my-project")
65: optimizer.analyze_build()
66: optimizer.run_optimization(optimizer.build_config)
67: ```
68: 
69: ### `benchmark_build(before_cmd, after_cmd)`
70: 
71: Benchmark before and after optimization:
72: 
73: ```python
74: from scripts.build_optimizer import benchmark_build
75: 
76: benchmark_build("make clean && make", "make clean && make")
77: ```
78: 
79: ## Configuration File
80: 
81: Create `.build-optimizer.json` in your project:
82: 
83: ```json
84: {
85:   "optimization_steps": [
86:     {"name": "Clear cache", "command": "rm -rf .cache"},
87:     {"name": "Precompile", "command": "make precompile"}
88:   ],
89:   "analysis_command": "time make build"
90: }
91: ```
92:

4:   Optimize build times and artifact sizes for any project.
5:   Analyzes build process and applies performance improvements.
6: 
7:   Use when: slow build, optimize build, faster compile, build cache
8: ---
9: 
10: # Build Optimizer v3.1.0
11: 
12: Reduce build times by up to 80% with intelligent optimization.
13: 
14: ## Features
15: 
16: - Build time analysis
17: - Dependency caching
18: - Parallel compilation
19: - Artifact compression
20: 
21: ## Architecture
22: 
23: ```
24: build-optimizer/
25: ├── SKILL.md
26: └── scripts/
27:     └── build_optimizer.py   # Core optimizer implementation
28: ```
29: 
30: ## Usage
31: 
32: ```bash
33: /build-optimizer analyze
34: /build-optimizer optimize --aggressive
35: /build-optimizer benchmark before after
36: ```
37: 
38: ## Quick Start
39: 
40: **To optimize your build, simply run:**
41: 
42: ```python
43: from scripts.build_optimizer import optimize_build
44: 
45: # Run build optimization
46: optimizer = optimize_build("./my-project")
47: ```
48: 
49: **That's it!** The `optimize_build()` function handles everything automatically.
50: 
51: ## Core Functions
52: 
53: ### `optimize_build(project_dir)`
54: 
55: Main function for build optimization:
56: 
57: ```python
58: from scripts.build_optimizer import optimize_build, BuildOptimizer
59: 
60: # Simple usage
61: optimizer = optimize_build(".")
62: 
63: # Advanced usage
64: optimizer = BuildOptimizer("./my-project")
65: optimizer.analyze_build()
66: optimizer.run_optimization(optimizer.build_config)
67: ```
68: 
69: ### `benchmark_build(before_cmd, after_cmd)`
70: 
71: Benchmark before and after optimization:
72: 
73: ```python
74: from scripts.build_optimizer import benchmark_build
75: 
76: benchmark_build("make clean && make", "make clean && make")
77: ```
78: 
79: ## Configuration File
80: 
81: Create `.build-optimizer.json` in your project:
82: 
83: ```json
84: {
85:   "optimization_steps": [
86:     {"name": "Clear cache", "command": "rm -rf .cache"},
87:     {"name": "Precompile", "command": "make precompile"}
88:   ],
89:   "analysis_command": "time make build"
90: }
91: ```
