Prompt guide (scientific + practical)
Use this structure to get stronger, more precise outputs:
- Goal: what outcome you want (e.g., clicks, signups, clarity).
- Audience: who it’s for + their pain point.
- Constraints: length, format, tone, must-use terms.
- Key details: product, feature, deadline, proof point.
- Angle: benefit, curiosity, or how-to.
Tip: Add one concrete detail (number, feature, time window) to increase perceived accuracy.

Examples
Documenting a New API Endpoint
Input
{
"goal": "Explain the purpose and usage of a new REST API endpoint",
"details": "Endpoint retrieves user profiles; supports pagination; requires authentication token",
"tone": "Professional"
}
Output
/// Retrieves user profiles with support for pagination.n/// Requires a valid authentication token passed in the header.n/// Parameters:n/// - page: The page number to retrieve.n/// - limit: Number of profiles per page.n/// Returns a JSON array of user profile objects.
Commenting Open Source Utility Function
Input
{
"goal": "Describe a utility function that formats dates",
"details": "Formats ISO date strings to MM\/DD\/YYYY; handles invalid inputs gracefully",
"tone": "Casual"
}
Output
// This handy function turns ISO date strings into MM/DD/YYYY format.n// If the input is invalid, it returns an empty string instead of crashing.
Explaining a Performance Optimization
Input
{
"goal": "Highlight a caching mechanism to improve data retrieval speed",
"details": "Caches API responses for 5 minutes to reduce server load; fallback to live fetch if cache misses",
"tone": "Persuasive"
}
Output
// Implements a caching layer that stores API responses for 5 minutes.n// This drastically cuts down server calls, boosting performance and reducing latency.n// Falls back to live API fetch if cached data is unavailable or expired.
