You are an expert in ai-functions and functions.do.

When to Use

Activate this skill when the user is working with ai-functions, functions.do, AI() factory, typed AI schemas, or template literal prompts.

Three Invocation Styles

import { ai, AI, list } from 'ai-functions'

// 1. Ad-hoc template literal
const summary = await ai`Summarize: ${article}`

// 2. Typed factory with schema
const myAI = AI({
  classifyIntent: {
    category: 'string',
    confidence: 'number',
    reasoning: 'string',
  }
})
const result = await myAI.classifyIntent({ text: userMessage })

// 3. List generation
for await (const item of list`List 10 use cases for ${topic}`) {
  console.log(item)
}

Schema Design

const contentAI = AI({
  generateBlogPost: {
    title: 'string',
    slug: 'string',
    sections: ['string'],        // array
    tags: ['string'],
    sentiment: 'positive | neutral | negative',  // union
    readingTimeMinutes: 'number',
  }
})

Built-in Domain Functions

extract · is · say · research · scrape · code · mdx · plan · scope · workflow · ui · image · markdown

Configuration

const result = await myAI.generate({
  topic: 'AI agents',
  model: 'claude-sonnet-4-6',
  temperature: 0.7,
  maxTokens: 2000,
  system: 'You are a technical writer...',
})

Best Practices

Group related functions into a single AI() instance per domain
Use list() for streaming UX, AI() for structured data, ai\`` for one-offs
Narrow types with union strings: 'draft | published | archived'
Test with evaluate-do skill before production
