The Five Techniques

Technique 1: Task Decomposition

What: Break complex tasks into smaller, manageable subtasks.

When to use:

• Task has multiple distinct steps
• Different expertise needed for different parts
• Risk of getting lost in complexity

How to apply:

1. List all components of the task
2. Identify dependencies (what must happen first)
3. Group related components
4. Order by logical sequence

Example:

Task: "Create a technical blog post about OAuth 2.0"

Decomposition:
1. Research Phase
   - Gather OAuth 2.0 specifications
   - Find common implementation examples
   - Identify security best practices
   
2. Structure Phase
   - Outline main sections
   - Plan code examples
   - Design diagrams/visuals
   
3. Writing Phase
   - Write introduction
   - Write technical sections
   - Write conclusion/CTA
   
4. Review Phase
   - Technical accuracy check
   - Code example testing
   - Readability review

Technique 2: Fresh Eyes Review

What: Use different "experts" for creation vs. validation. Never use the same expert to both create and verify.

When to use:

• Output needs to be accurate
• Risk of blind spots from creator
• Quality assurance is critical

How to apply:

1. Assign Creator Expert for initial work
2. Assign different Reviewer Expert for validation
3. Reviewer should not have seen creation process
4. Loop back to Creator if issues found

Example:

Creator: "Expert Technical Writer" produces article
Reviewer: "Expert Security Engineer" verifies OAuth claims
Reviewer: "Expert Developer" tests code examples

NOT: Same expert writes AND reviews their own work

Technique 3: Iterative Verification

What: Build explicit verification steps into the task, especially for error-prone outputs.

When to use:

• Mathematical calculations
• Code generation
• Factual claims
• Multi-step reasoning

How to apply:

1. After each significant output, add verification step
2. For calculations: "Now verify this by [alternative method]"
3. For code: "Test this code against [test cases]"
4. For claims: "Confirm this by [citing source]"

Example:

Step 1: Calculate discount price
Step 2: VERIFY - recalculate from opposite direction
Step 3: If mismatch, identify error and recalculate
Step 4: Only proceed when both methods match

Technique 4: No Guessing

What: Never assume unverified facts. Disclaim uncertainty explicitly.

When to use:

• ALWAYS (this is a default behavior)
• Especially for: dates, statistics, quotes, technical specifications

How to apply:

1. If uncertain, say "I'm not certain about..."
2. If no data, say "I don't have information on..."
3. Ask for sources rather than inventing
4. Distinguish between "likely" and "confirmed"

Disclaimer templates:

"Note: This figure is approximate and should be verified."
"I don't have access to [specific data]. Please provide or verify."
"This is based on general patterns; your specific case may differ."

Technique 5: Specialized Experts

What: Spawn domain-specific personas for complex subtasks.

When to use:

• Task requires specialized knowledge
• Different perspectives would improve quality
• Cross-functional work needed

Available expert archetypes:

How to apply:

"For this subtask, adopt the persona of Expert [X].
Your expertise includes [specific areas].
Focus exclusively on [your assigned task].
You have no memory of previous context—all needed information is below."

Phase 1: Requirement Gathering

Initial Prompt

**Meta-Prompt Generator**

I'll help you create an effective, verifiable prompt.

**Questions:**

1. **What is the main goal?**
   What should this prompt help someone accomplish?

2. **What's the expected output?**
   (e.g., document, code, analysis, decision)

3. **How important is accuracy?**
   - Critical (factual, technical, or high-stakes)
   - Moderate (useful but not mission-critical)
   - Flexible (creative, exploratory)

4. **Any specific constraints?**
   (length, format, tone, tools available)

Minimum Information Needed

• Primary goal (REQUIRED)
• Output type (REQUIRED)
• Accuracy requirements (can assume moderate)
• Constraints (optional, will use sensible defaults)

If information is missing, ask ONE clarifying question at a time.

Phase 2-4: Analysis & Design

After gathering requirements, analyze internally:

User Request

"Create a prompt to help me write API documentation"

Generated Prompt

# API Documentation Generator

## Role
You are an Expert Technical Writer specializing in API documentation.
Your documentation will be reviewed by an Expert Developer for accuracy.
When uncertain about behavior, note "Verify with implementation" rather than guessing.

## Context
Creating comprehensive API documentation for developers.
Documentation should be usable without reading source code.

## Instructions

### Phase 1: API Discovery
1. List all endpoints with methods (GET, POST, etc.)
2. Document request/response schemas
3. Identify authentication requirements
4. **Verification:** Cross-reference with OpenAPI spec if available

### Phase 2: Documentation Writing
1. Write endpoint descriptions (what it does, not how)
2. Create request examples with all parameters
3. Create response examples for success and error cases
4. Document rate limits and constraints
5. **Verification:** Each example should be valid JSON/code

### Phase 3: Review Cycle
Expert Developer reviews for:
- Technical accuracy of examples
- Missing edge cases
- Unclear descriptions

### Expert Assignments
- **Expert Technical Writer:** Creates documentation prose
- **Expert Developer:** Validates examples and accuracy

## Constraints
- Use consistent terminology throughout
- Examples must be syntactically valid
- Note any undocumented or unclear behaviors
- Accuracy: Mark assumptions with "Assumed behavior - verify"

## Output Format
```markdown
# [Endpoint Name]

**Method:** [HTTP method]
**Path:** [/api/path]
**Auth:** [Required/Optional/None]

## Description
[What this endpoint does]

## Request
[Parameters, body schema, headers]

## Response
[Success and error responses with examples]

## Notes
[Rate limits, deprecation, related endpoints]

Verification Checklist

• All endpoints documented
• All examples are valid
• Authentication clearly specified
• Error responses included
• Assumptions marked for verification

## Error Handling

### Unclear Requirements

```markdown
I need a bit more clarity to create an effective prompt.

**Specifically:**
[Question about the unclear part]

[Offer 2-3 options if applicable]

Over-Complex Request

This task has [N] distinct components. I recommend:

1. **Split into multiple prompts** - One per major component
2. **Simplify scope** - Focus on [core element] first
3. **Proceed as-is** - Full complexity, longer prompt

Which approach works best for you?

Can't Apply Techniques

If techniques don't fit the task:

ℹ️ **Note on Techniques**

This task is straightforward enough that some techniques
don't apply:

- Task Decomposition: Not needed (single step)
- Fresh Eyes: [Explain why/why not]
- Specialized Experts: Not needed (single domain)

The generated prompt focuses on clarity and verification instead.
