masterchef

Recipe and ingredient query assistant. Use when users ask how to cook X, X recipe, what can I make with X, I have X what can I cook, how to make X, or mention cooking, recipe, ingredients, dish, food preparation, meal, cuisine. Supports searching by ingredients or by dish name. Also triggers on Chinese keywords: 怎么做X, 做法, 食材, 菜谱, 做菜, 烹饪, 料理, 食谱.

MasterChef - Recipe Assistant

MasterChef is a cooking assistant powered by the api.yummy.chat recipe knowledge base.

Overview

MasterChef provides two core features:

1. Ingredient Search: Tell me what ingredients you have (1-3 items), and I'll show you what dishes you can make
2. Recipe Lookup: Tell me a dish name, and I'll give you the full recipe

When to Use This Skill

Activate this skill when the user's request involves:

• Asking about recipes: "how to make mapo tofu", "recipe for cola chicken wings", "how to cook fried rice"
• Asking about ingredient pairings: "what can I make with eggplant and potato", "I have chicken wings, what can I cook"
• Expressing cooking intent: "want to eat braised pork", "what should I cook today"
• Mentioning cooking keywords: recipe, cooking, ingredients, dish, meal, cuisine, food prep

Language Handling (IMPORTANT)

The API only accepts Chinese input and returns Chinese output. You must handle translation:

1. Input translation: If the user writes in English, translate ingredient names or dish names to Chinese before calling the API

   • "eggplant" → "茄子", "potato" → "土豆", "chicken wings" → "鸡翅"
   • "cola chicken wings" → "可乐鸡翅", "mapo tofu" → "麻婆豆腐"
   • "how to make stir-fried eggplant" → dish_name: "烧茄子"

2. Output translation: Translate the full API response back to the user's language (English)

   • Translate dish names, ingredient lists, cooking steps, tips, and all other content
   • Preserve the original structure and formatting
   • Do NOT omit or add any information during translation

If the user writes in Chinese, no translation is needed — pass Chinese directly to the API and return Chinese output as-is.

Usage Guide

Detecting User Intent

Ingredient search mode — when the user:

• Mentions "I have", "I've got", "in my fridge"
• Asks "what can I make with X", "what to cook with X"
• Lists multiple ingredient names

Recipe lookup mode — when the user:

• Asks "how to make X", "recipe for X", "how to cook X"
• Says "want to eat X", "make some X"
• Mentions a specific dish name

Priority: If unsure, try recipe lookup first (it's more specific).

1. Ingredient Search Mode

Steps:

1. Extract ingredient names: Identify 1-3 ingredients from user input

   • Example: "I have eggplant and potato" → ["茄子", "土豆"]
   • Example: "what can I make with chicken wings" → ["鸡翅"]

2. Call API:

bash

curl -s -X POST https://api.yummy.chat/ingredients \
  -H "Content-Type: application/json" \
  -d '{"ingredients": ["食材1", "食材2"]}'

3. Parse response: Extract dishes list from each ingredient in results

4. Translate and format output: See "Output Format Guide" below

2. Recipe Lookup Mode

Steps:

1. Extract dish name: Identify the dish name from user input

   • Example: "how to make Di San Xian" → "地三鲜"
   • Example: "want to eat cola chicken wings" → "可乐鸡翅"

2. Call API:

bash

curl -s -X POST https://api.yummy.chat/howtocook \
  -H "Content-Type: application/json" \
  -d '{"dish_name": "菜名"}'

3. Parse response: Extract recipe content from recipes array

4. Translate and format output: See "Output Format Guide" below

Output Format Guide

Ingredient Search Results

Principles:

• Group results by ingredient
• Highlight dishes that use multiple queried ingredients together
• Use emoji for readability
• Categorize (recommended, quick & easy, advanced, etc.)
• Translate all dish names and descriptions to the user's language

Recipe Lookup Results

Principles:

• Show the most common/standard version first: If the API returns multiple versions, only display the first one (typically the most standard)
• Return the full recipe as-is: Do not omit or add any information — translate the complete API response faithfully
• If multiple variants exist, briefly mention them without expanding

Error Handling

HTTP 404 - Recipe Not Found

The dish name doesn't exist in the knowledge base. Tell the user the recipe wasn't found, suggest checking the spelling or trying an alternative name.

HTTP 422 - Parameter Error

Invalid input (wrong number of ingredients, empty string). Guide the user to provide 1-3 ingredient names or a specific dish name.

HTTP 502 - Service Error

The backend knowledge base service is unavailable. Ask the user to try again later.

Network Error

Cannot connect to api.yummy.chat. Suggest checking the network connection.
