menkesu/ai-startup-building
Builds AI-native products using Dan Shipper's 5-product playbook and Brandon Chu's AI product frameworks. Use when implementing prompt engineering, creating AI-native UX, scaling AI products, or optimizing costs. Focuses on 2025+ best practices.

Claude uses this skill when:
Key Principles:
Modern Approach:
- Use structured outputs (JSON)
- Implement streaming
- Design for retry logic
- Plan for model switching
- Cache aggressively
Strategies:
// Modern AI product pattern (2025)
interface AIFeature {
// Streaming for responsiveness
async *stream(prompt: string): AsyncGenerator<string> {
const cached = await checkCache(prompt);
if (cached) return cached;
// Route to appropriate model
const model = this.selectModel(prompt);
for await (const chunk of model.stream(prompt)) {
yield chunk;
}
}
// Model selection (cost optimization)
selectModel(prompt: string): Model {
if (this.isSimple(prompt)) {
return this.smallModel; // Fast, cheap
} else {
return this.largeModel; // Smart, expensive
}
}
// Retry logic (reliability)
async withRetry<T>(fn: () => Promise<T>): Promise<T> {
for (let i = 0; i < 3; i++) {
try {
return await fn();
} catch (e) {
if (i === 2) throw e;
await sleep(Math.pow(2, i) * 1000);
}
}
}
}
# AI Cost Analysis: [Feature]
## Current Usage
- Daily requests: [X]
- Model: [GPT-4/Claude/etc.]
- Cost per 1K requests: [$X]
- Monthly cost: [$Y]
## Optimization Plan
### 1. Caching (Est. 80% hit rate)
- Before: [100]% paid calls
- After: [20]% paid calls
- Savings: [80]%
### 2. Model Routing
- Simple queries ([60]%): Small model
- Complex queries ([40]%): Large model
- Savings: [50]%
### 3. Batching
- Real-time: [X]% of requests
- Batchable: [Y]% of requests
- Savings: [Z]%
## Projected Cost
- Before optimization: [$X/month]
- After optimization: [$Y/month]
- Reduction: [Z]%

Key Insights:
Dan Shipper:
> "AI doesn't replace PMs. It makes small PM teams as powerful as large ones."
On Prompt Engineering:
> "The best prompts in 2025 are structured, explicit, and tested with evals."
Brandon Chu:
> "Build for the AI you'll have in 6 months, not the AI you have today."
