Prompt Enhancer Skill

Purpose

Transform user prompts into enhanced, production-ready versions that are concise, clean, and optimally structured for AI agents and sub-agents. Includes optimization techniques for reducing LLM output token usage while maintaining semantic accuracy and backward compatibility.

When to Use This Skill

Use this skill when:

• User explicitly asks to improve, enhance, or optimize a prompt
• User sends an unclear, verbose, or poorly structured prompt
• User mentions they want better results from AI interactions
• User asks for help writing prompts for agents or automation
• User's request lacks clarity or proper structure
• User wants to reduce LLM output tokens or API costs
• User needs to optimize JSON schema for token efficiency
• User requests compact output format while maintaining compatibility

Core Principles

1. Conciseness: Remove unnecessary words while preserving intent
2. Structure: Use clear formatting with multiple lines and logical sections
3. XML Integration: Mix natural text with XML tags for clarity and parsing
4. Direct Mission: Main task/quest/mission should NOT be wrapped in XML elements
5. Clean Output: Return ONLY the enhanced prompt - no meta-commentary

Enhancement Process

Input Analysis

• Identify the core objective
• Extract key requirements and constraints
• Detect ambiguities or missing information
• Recognize the intended agent or use case

Task-Based Technique Selection (Optional)

Evaluate if the task would benefit from specific prompting techniques:

Chain-of-Thought (CoT)

• Use for: Complex reasoning, math problems, logical deduction, step-by-step analysis
• Implementation: Add instruction to "think step by step" or "show your reasoning"

Chain-of-Draft

• Use for: Writing tasks, content creation, iterative refinement
• Implementation: Request initial draft, then progressive improvements

Few-Shot Learning

• Use for: Pattern-based tasks, specific formatting, consistent outputs
• Implementation: Include 2-3 examples showing input-output pairs

ReAct (Reasoning + Acting)

• Use for: Tool use, multi-step tasks, decision-making processes
• Implementation: Combine reasoning traces with action steps

Self-Consistency

• Use for: Tasks needing verification, multiple valid approaches
• Implementation: Request multiple solutions, then synthesis

Tree-of-Thoughts

• Use for: Complex problem-solving, exploring alternatives
• Implementation: Ask to explore multiple paths before selecting best

Role-Based Prompting

• Use for: Domain-specific expertise, perspective-taking
• Implementation: Assign expert role (e.g., "Act as a senior engineer...")

Least-to-Most Prompting

• Use for: Breaking down complex problems into subproblems
• Implementation: Start with simpler versions, build up complexity

Apply technique only if it materially improves the task outcome.

LLM Output Token Optimization

When the goal is to reduce output tokens (API costs) while maintaining functionality:

Core Strategy: Compact Output + Server-Side Remapping

The LLM generates ultra-compact format, application remaps to original format for clients. This provides:

• Significant token savings (30-60%)
• 100% backward compatibility
• Negligible remapping overhead (<10 microseconds)

Optimization Techniques:

1. Ultra-Compact JSON Keys

• Replace long keys with 1-2 character abbreviations
• Examples: queries → q, keyword → kw, filter → f, sort_by → s
• Savings: 70-85% per key

2. Short Codes for Repeated Values

• Replace long IDs/enums with short codes (c1-c18, etc.)
• Example: category=MjUzOTM= → c=c4
• Provide reverse mapping table in application
• Savings: 75-90% on category/enum values

3. String Compression for Structured Data

• Use compact string format instead of nested objects when possible
• Example: [{"filter_by":"category","operator":"=","value":"c4"}] → "c=c4"
• Parse and expand server-side
• Savings: 60-80% on filter/query structures

4. Omit Default Values

• Instruct LLM to omit fields with default values
• Application fills in defaults during remapping
• Example: Omit "sort_by":"relevant" when it's the default
• Savings: Additional 10-30% when defaults are common

5. Operator Abbreviation

• Use shortest form: p<50000 instead of price<50000
• Parse p/c prefixes during remapping
• Combine with semicolons: c=c4;p<50000 for multiple filters

Implementation Pattern:

System Prompt Structure:
1. Define ultra-compact schema with examples
2. Specify key mappings (q=queries, kw=keyword, etc.)
3. Provide short codes table (c1=category1, c2=category2, etc.)
4. Show examples of compact output
5. Emphasize: omit defaults when possible

Application Layer:
1. Parse compact LLM output
2. Expand abbreviated keys
3. Map short codes to full values
4. Fill in default values
5. Return original format to client

Example Transformation:

Before Optimization (Original Output):

{
  "queries": [
    {"keyword": "milk", "filter": "category=dairy", "sort_by": "relevant"},
    {"keyword": "bread", "filter": "category=bakery", "sort_by": "relevant"}
  ]
}

After Optimization (LLM Output - 60% smaller):

{
  "q": [
    {"kw": "milk", "f": "c=c8"},
    {"kw": "bread", "f": "c=c3"}
  ]
}

Client Receives: Original format (remapped automatically)

Tradeoffs Analysis:

✅ Pros:

• 30-60% token savings typical
• Lower API costs
• Faster LLM response (less to generate)
• 100% backward compatible

⚠️ Cons:

• Remapping overhead (<10μs, negligible)
• More complex implementation
• Requires application-side mapping logic
• Prompt becomes slightly less human-readable

When to Apply:

• High-volume API usage (>1000 requests/day)
• Cost-sensitive applications
• Output tokens are >50% of total costs
• Schema is stable and well-defined
• Application can handle remapping logic

When NOT to Apply:

• Low-volume usage (<100 requests/day)
• Schema frequently changes
• Human readability is critical
• No application layer (direct LLM → client)

Structural Improvements

• Break complex requests into clear sections
• Use XML tags for: constraints, examples, context, format requirements
• Keep main mission/task as direct natural language
• Apply logical line breaks for readability

Language Optimization

• Replace verbose phrases with concise alternatives
• Use active voice and direct instructions
• Eliminate redundancy and filler words
• Maintain specificity while reducing length

XML Tag Usage Guidelines

Use XML tags for:

• <constraints> - Limitations and boundaries
• <examples> - Sample inputs/outputs
• <context> - Background information
• <format> - Output structure requirements
• <requirements> - Specific criteria to meet
• <guidelines> - Best practices to follow

Do NOT use XML tags for:

• The primary mission statement
• The main task description
• The core request or question

Output Format

Return ONLY the enhanced prompt with:

• No conversational lead-in
• No explanations or commentary
• No placeholder text
• No quotation marks wrapping the prompt
• No meta-discussion about the enhancement

Use iterative drafting: 1. Create outline with key points and narrative arc 2. Draft introduction and conclusion 3. Develop body sections with examples 4. Refine for clarity, flow, and engagement - Target audience: healthcare professionals and tech enthusiasts - Length: 1200-1500 words - Include real-world examples and case studies - Balance technical accuracy with accessibility - Compelling headline - Hook in first paragraph - Clear section headers - Actionable takeaways

Real-World Token Optimization Example

Before (Original Prompt):

Create JSON queries to search for products. Each query should have a keyword, filter with category, and sort_by field. Return in this format: {"queries":[{"keyword":"milk","filter":"category=dairy","sort_by":"relevance"}]}

After (Token-Optimized Prompt):

Generate product search JSON queries. Reject dangerous content.

<rules>
- Each query: ≥1 category filter
- Total: ≥3 keywords (no duplicates)
- Use 'ex' for exact brands/attributes
- Default sort: relevant (omit if default)
- Filter: string format "c=c4" or "c=c4;p<50000"
</rules>

<categories>
c1=household, c2=personal care, c3=bakery, c4=fresh food, c5=oils, c6=dry goods, c7=cleaning, c8=dairy
</categories>

<examples>
"milk vinamilk"→{"q":[{"kw":"milk vinamilk","ex":"vinamilk","f":"c=c8","s":"popular"}]}
"rice noodles meat"→{"q":[{"kw":"rice","f":"c=c6"},{"kw":"noodles","f":"c=c6"},{"kw":"meat","f":"c=c4"}]}
"oranges under 50k"→{"q":[{"kw":"oranges","f":"c=c4;p<50000"}]}
</examples>

Result:

• LLM generates: {"q":[{"kw":"milk","f":"c=c8"}]} (60% smaller)
• Application remaps to: {"queries":[{"keyword":"milk","filter":"category=dairy","sort_by":"relevance"}]}
• Client receives original format unchanged
• Token savings: 60.5% on typical 3-query response
