startup-time-profiler
Profile and optimize application startup time for desktop applications
Best use case
startup-time-profiler is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Profile and optimize application startup time for desktop applications
Teams using startup-time-profiler should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# startup-time-profiler
Profile and optimize application startup time, identifying bottlenecks in initialization, module loading, and rendering.
## Capabilities
- Measure cold and warm start times
- Identify module loading bottlenecks
- Profile initialization phases
- Generate timeline visualizations
- Provide optimization recommendations
- Set up CI performance tracking
## Input Schema
```json
{
"type": "object",
"properties": {
"projectPath": { "type": "string" },
"framework": { "enum": ["electron", "tauri", "native"] },
"iterations": { "type": "number", "default": 5 }
},
"required": ["projectPath"]
}
```
## Electron Startup Profiling
```javascript
// Add to main.js
const startTime = Date.now();
app.on('ready', () => {
console.log(`App ready: ${Date.now() - startTime}ms`);
});
// Enable tracing
app.commandLine.appendSwitch('trace-startup');
app.commandLine.appendSwitch('trace-startup-file', 'startup-trace.json');
```
## Optimization Techniques
1. Lazy load modules
2. Defer non-critical initialization
3. Optimize bundle size
4. Use V8 snapshots
5. Preload critical resources
## Benchmarks
| Metric | Good | Acceptable | Poor |
|--------|------|------------|------|
| Cold start | < 2s | < 4s | > 6s |
| Warm start | < 1s | < 2s | > 3s |
| Window visible | < 1.5s | < 3s | > 5s |
