Prompt Engineering

Overview

This skill transforms vague user requests into precise, effective prompts through collaborative dialogue, systematic analysis, and iterative refinement. It combines proven prompt engineering techniques with a structured development process to create prompts that reliably achieve user objectives.

Workflow Decision Tree

When a user requests prompt assistance, follow this decision flow:

User Request
├─ "Create a prompt" / "Make a prompt" / Vague request
│  └─ → Start with EXPLORATION PHASE
├─ "Optimize this prompt" / Has existing prompt
│  └─ → Start with SIMPLE OPTIMIZATION
└─ "Fix this issue with my prompt" / Specific problem
   └─ → Start with ANALYSIS PHASE (focused on problem)

Core Process

Phase 1: Exploration - Uncovering True Needs

Before creating any prompt, deeply understand the user's actual needs through strategic questioning. Start broad, then narrow down systematically.

Initial Context Gathering:

• What task will this prompt accomplish?
• Who will use it and in what environment?
• How frequently will it be used?
• What does success look like?

Deepening Understanding:

• Request concrete examples of desired outputs
• Ask about past failures or attempts
• Identify critical success factors
• Uncover unstated assumptions and constraints

Technical Requirements:

• Model and platform constraints
• Token limits and cost considerations
• Response time requirements
• Integration with other systems

Continue exploration until the core requirements are crystal clear. Never assume—always verify.

Phase 2: Analysis - Choosing the Right Strategy

Analyze the task to determine the optimal prompting approach.

Task Classification:

Classify the task along key dimensions:

• Complexity: Simple directive vs multi-step reasoning
• Output Type: Creative vs analytical vs structured
• Error Tolerance: High-stakes vs experimental
• Frequency: One-time vs repeated use

Strategy Selection:

Based on classification, choose primary techniques:

• Simple Tasks: Direct instructions with clear constraints
• Complex Reasoning: Chain-of-thought with step-by-step breakdown
• Creative Tasks: Role setting with flexible boundaries
• Structured Output: Explicit format specifications with examples
• High-Stakes: Self-consistency checks and validation steps

Trade-off Analysis:

Present multiple approaches with clear trade-offs:

• Approach A: Detailed but token-heavy
• Approach B: Concise but requires interpretation
• Approach C: Balanced with moderate complexity

Always explain WHY each approach fits the specific context.

Phase 3: Implementation - Building Iteratively

Create the prompt through progressive refinement, starting simple and adding complexity as needed.

Version 1 - Minimal Viable Prompt:

• Core instructions only
• Test basic functionality
• Identify gaps and ambiguities

Version 2 - Enhanced Clarity:

• Add specific examples if needed
• Clarify ambiguous points
• Include essential constraints

Version 3+ - Optimization:

• Refine wording for precision
• Remove redundancy
• Balance detail with conciseness

Document each version's changes and rationale. Store prompts in markdown files with:

• Version history
• Design decisions
• Known limitations
• Usage examples

Phase 4: Validation - Critical Evaluation

Rigorously evaluate the prompt against quality criteria.

Essential Checks:

• Clarity: Can the instructions be misunderstood?
• Completeness: Are all necessary elements present?
• Consistency: Do instructions contradict each other?
• Efficiency: Can anything be removed without loss?
• Robustness: How does it handle edge cases?

Testing Approach:

• Run through typical use cases
• Test boundary conditions
• Imagine failure modes
• Check for unwanted behaviors

Be ruthlessly honest about weaknesses. If something isn't working, acknowledge it and iterate.

Simple Optimization

When optimizing an existing prompt, focus on minimal, targeted improvements:

1. Identify Specific Issues: What exactly isn't working?
2. Diagnose Root Causes: Why is the current prompt failing?
3. Apply Minimal Edits: Change only what's necessary
4. Preserve Working Elements: Keep what already works well
5. Test Improvements: Verify fixes don't break other aspects

Common optimization targets:

• Ambiguous language → Specific instructions
• Missing constraints → Added boundaries
• Inconsistent outputs → Format specifications
• Verbose responses → Length constraints
• Off-topic responses → Clearer scope definition

Prompt Creation from Scratch

When creating new prompts, structure them as instructions for an eager but inexperienced assistant who needs clear guidance.

Essential Components:

1. Role/Context (if beneficial):

- Set perspective or expertise level - Establish tone and approach

1. Clear Objective:

- State the primary goal explicitly - Define success criteria

1. Specific Instructions:

- Break complex tasks into steps - Provide decision criteria - Specify constraints and boundaries

1. Output Format (when relevant):

- Define structure explicitly - Provide format examples - Specify length or detail level

1. Examples (when clarifying):

- Show desired patterns - Illustrate edge cases - Demonstrate style/tone

Key Techniques Reference

Foundation Techniques

Role Setting: Establish perspective when expertise or tone matters

• Effective for: Specialized knowledge, consistent voice
• Example: "As an experienced code reviewer, analyze..."

Progressive Disclosure: Start general, add detail as needed

• Effective for: Complex multi-part tasks
• Example: "First outline the approach, then implement each section..."

Explicit Constraints: Define boundaries clearly

• Effective for: Preventing unwanted outputs
• Example: "Limit response to 3 paragraphs, focus only on technical aspects"

Advanced Techniques

Chain-of-Thought: Request reasoning before conclusions

• Use when: Logic and transparency matter
• Trigger: "Think step-by-step" or "Explain your reasoning"

Few-Shot Learning: Provide input-output examples

• Use when: Pattern is easier shown than explained
• Caution: 2-3 examples usually sufficient

Self-Consistency: Have model verify its own outputs

• Use when: Accuracy is critical
• Implementation: "Review your answer for errors and inconsistencies"

Collaboration Principles

Be a Thought Partner, Not Just an Executor

• Bad: "Here's your prompt" (without understanding needs)
• Good: "Let me understand what you're trying to achieve first..."

Question Assumptions Constructively

• Surface hidden requirements through dialogue
• Challenge unclear objectives respectfully
• Propose alternatives when original approach seems suboptimal

Iterate Based on Feedback

• Start with minimum viable prompt
• Test and refine based on actual outputs
• Document what works and what doesn't

Teach While Doing

• Explain why certain techniques work
• Share the reasoning behind design choices
• Help users understand prompt engineering principles
