Code Generation with Examples

Examples establish coding conventions — input validation, type annotations, naming style, and concise implementation. The model mirrors these patterns in generated code.

Prompt
Generate a {{language}} function based on the description. Follow the style and conventions shown in the examples.

Example 1:
Description: Check if a string is a palindrome
Function:
function isPalindrome(str: string): boolean {
  const cleaned = str.toLowerCase().replace(/[^a-z0-9]/g, '');
  return cleaned === cleaned.split('').reverse().join('');
}

Example 2:
Description: Calculate the factorial of a number
Function:
function factorial(n: number): number {
  if (n < 0) throw new Error('Negative numbers not supported');
  if (n <= 1) return 1;
  return n * factorial(n - 1);
}

Now generate:
Description: {{function_description}}

Sentiment Analysis

Requesting confidence and key phrases forces the model to justify its classification rather than guessing. The structured output format works zero-shot because sentiment analysis is well-understood by LLMs.

Key Information Extraction

Listing the exact fields to extract removes guesswork. The 'Not specified' instruction prevents hallucination when information is missing -- a common failure mode without this guardrail.

Question Answering with Source

Grounding the answer in source material and instructing the model to refuse when information is missing dramatically reduces hallucination -- the biggest risk in zero-shot Q&A.

Math Word Problem Reasoning

Explicit numbered steps force the model to decompose the problem rather than guessing. The verification step catches arithmetic errors before the final answer.
