## generate Instructions

Effective instructions are specific about what to produce and how to transform the source content.

### Summarize and categorize

Schema: `{stories: [{title, category, summary}]}`

> "For each story on the page, categorize it as tech/business/science/politics/other and write a one-sentence summary."

### Sentiment analysis

Schema: `{reviews: [{text, sentiment, score}]}`

> "For each review, determine the sentiment (positive/negative/neutral) and assign a score from 1-5."

### Extract and reformat

Schema: `{recipes: [{name, prep_time, ingredients, steps}]}`

> "Extract all recipes from this page. List ingredients as an array of strings. Summarize each step in one sentence."

### Competitive analysis

Schema: `{products: [{name, price, pros, cons, verdict}]}`

> "Compare the products on this page. For each, list 2-3 pros and cons, then give a one-sentence verdict."

### Content digest

Schema: `{digest: {title, key_points, action_items, tldr}}`

> "Create a digest of this page. Extract 3-5 key points as bullet-length strings, any action items mentioned, and a single-sentence TLDR."
