# Prompt Optimizer ## Overview This skill transforms user-provided prompts into high-quality, clear, and effective instructions optimized for AI models. Apply proven prompt engineering principles to enhance clarity, specificity, structure, and effectiveness. The skill uses a systematic workflow to analyze, identify improvement opportunities, and restructure prompts based on industry best practices. ## When to Use This Skill Activate this skill when users: - Explicitly request prompt optimization or improvement - Provide vague or unclear instructions that need refinement - Ask for help making their requests more effective - Submit poorly structured prompts that would benefit from reorganization - Request guidance on how to better communicate with AI models - Present complex tasks that need to be broken down into clearer instructions ## Optimization Workflow Follow this systematic process to optimize any prompt: ### Step 1: Analyze the Original Prompt Examine the user's prompt and identify: **Clarity issues:** - Ambiguous terms or vague requirements - Implicit assumptions that should be explicit - Missing context or background information **Specificity gaps:** - Lack of concrete constraints or requirements - Undefined success criteria - Missing audience or purpose information - Unclear scope or boundaries **Structure problems:** - Disorganized or stream-of-consciousness format - Missing logical flow - Lack of clear sections or hierarchy **Format considerations:** - No specified output format - Unclear expectations about length, tone, or style - Missing examples or templates **Complexity assessment:** - Determine if the task is too complex for a single prompt - Identify if the request would benefit from prompt chaining - Assess if step-by-step reasoning is needed ### Step 2: Identify the Core Intent Determine the fundamental objective behind the user's request: - What is the user ultimately trying to accomplish? - What problem are they trying to solve? - What would constitute a successful output? - Who is the intended audience or consumer of the output? Clarify these points with the user if they are not evident from the original prompt. ### Step 3: Apply Optimization Principles Enhance the prompt using these core principles: **Make it clear and direct:** - State requirements explicitly without assuming inference - Remove ambiguity and vague language - Use concrete, specific terms **Provide context and motivation:** - Explain WHY certain requirements matter - Include relevant background information - Describe the use case or scenario **Add specificity:** - Define concrete constraints (length, format, scope) - Specify target audience - Include quality criteria - State any limitations or boundaries **Structure the request:** - Organize information logically - Use clear sections or numbered points - Separate different types of information (context, requirements, format) **Include examples when helpful:** - Provide input-output examples for complex formats - Show desired tone or style through examples - Demonstrate edge case handling **Allow for uncertainty:** - Explicitly permit expressing "I don't know" - Request acknowledgment of limitations - Prevent hallucination by encouraging honesty ### Step 4: Consider Advanced Techniques Evaluate if any advanced techniques would enhance the prompt: **Chain of Thought:** - Apply when the task requires reasoning or analysis - Request step-by-step thinking for complex problems - Use structured format to separate reasoning from answer **Prefilling:** - Use when a specific format is absolutely required (JSON, XML) - Apply to eliminate unwanted preambles - Utilize to establish immediate tone or style **Prompt Chaining:** - Break complex tasks into sequential steps - Create a multi-stage workflow for intricate projects - Design each prompt to build on previous outputs **Structured Output:** - Specify exact format requirements - Provide schemas or templates - Use tags or delimiters for different sections
