# ai-prompt-engineering-safety-best-practices

This rule guides prompt writing with clear context, constraints, and output formats. It also asks developers to consider safety and bias when creating or reviewing prompts.

## What it does

The rule covers prompt basics: stating the task, supplying background, and setting constraints. It walks through zero-shot and few-shot prompting, role prompts, and step-by-step reasoning, with examples of unclear instructions. These patterns apply to tasks such as code generation and review, documentation, and data analysis.

In GitHub Copilot, the rule applies to every project file. It calls for considering safety, bias, and security alongside functionality when generating or reviewing prompts. It provides guidance; it does not automatically validate Copilot’s responses.

## Install

### GitHub Copilot (native platform)

**Manually: put the files in place**
- File: `.github/instructions/ai-prompt-engineering-safety-best-practices.instructions.md` — The applyTo field sets which files it applies to

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/ai-prompt-engineering-safety-best-practices.md` — The paths frontmatter field limits the files: move applyTo from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### Cursor

**Manually: put the files in place**
- File: `.cursor/rules/ai-prompt-engineering-safety-best-practices.mdc` — Frontmatter: description, globs, alwaysApply. Move applyTo from the source into globs, or the rule will not attach on its own

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/ai-prompt-engineering-safety-best-practices.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/ai-prompt-engineering-safety-best-practices.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/github/awesome-copilot/tree/HEAD/instructions/ai-prompt-engineering-safety-best-practices.instructions.md

## When to use it
- clarify a prompt’s task and expected output
- add context and constraints to a code-generation request
- choose a prompting pattern for a complex task
- review an instruction for ambiguity and bias risks

## Example prompts
- Review this prompt for ambiguity and security risks.
- Rewrite this request with relevant context, constraints, and an output format.
- Suggest a prompting pattern for a code review and explain why it fits.

# AI Prompt Engineering & Safety Best Practices

## Your Mission

As GitHub Copilot, you must understand and apply the principles of effective prompt engineering, AI safety, and responsible AI usage. Your goal is to help developers create prompts that are clear, safe, unbiased, and effective while following industry best practices and ethical guidelines. When generating or reviewing prompts, always consider safety, bias, security, and responsible AI usage alongside functionality.

## Introduction

Prompt engineering is the art and science of designing effective prompts for large language models (LLMs) and AI assistants like GitHub Copilot. Well-crafted prompts yield more accurate, safe, and useful outputs. This guide covers foundational principles, safety, bias mitigation, security, responsible AI usage, and practical templates/checklists for prompt engineering.

### What is Prompt Engineering?

Prompt engineering involves designing inputs (prompts) that guide AI systems to produce desired outputs. It's a critical skill for anyone working with LLMs, as the quality of the prompt directly impacts the quality, safety, and reliability of the AI's response.

**Key Concepts:**
- **Prompt:** The input text that instructs an AI system what to do
- **Context:** Background information that helps the AI understand the task
- **Constraints:** Limitations or requirements that guide the output
- **Examples:** Sample inputs and outputs that demonstrate the desired behavior

**Impact on AI Output:**
- **Quality:** Clear prompts lead to more accurate and relevant responses
- **Safety:** Well-designed prompts can prevent harmful or biased outputs
- **Reliability:** Consistent prompts produce more predictable results
- **Efficiency:** Good prompts reduce the need for multiple iterations

**Use Cases:**
- Code generation and review
- Documentation writing and editing
- Data analysis and reporting
- Content creation and summarization
- Problem-solving and decision support
- Automation and workflow optimization

## Prompt Engineering Fundamentals

### Clarity, Context, and Constraints

**Be Explicit:**
- State the task clearly and concisely
- Provide sufficient context for the AI to understand the requirements
- Specify the desired output format and structure
- Include any relevant constraints or limitations

**Example - Poor Clarity:**
```
Write something about APIs.
```

**Example - Good Clarity:**
```
Write a 200-word explanation of REST API best practices for a junior developer audience. Focus on HTTP methods, status codes, and authentication. Use simple language and include 2-3 practical examples.
```

**Provide Relevant Background:**
- Include domain-specific terminology and concepts
- Reference relevant standards, frameworks, or methodologies
- Specify the target audience and their technical level
- Mention any specific requirements or constraints

**Example - Good Context:**
```
