Skill17 starsChanged 9 months agoMITView on GitHub
Transform any rough prompt, task description, or job into an optimized AI instruction prompt. Use when users ask to "improve this prompt", "make this better for an AI", "optimize this for Claude/GPT", or provide raw instructions that need refinement into a well-structured prompt following best practices.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
7 rules. 0 are common, 7 are distinctive, and 0 are very specific to this project.
0
Common
Most of the 8 edited versions we read keep these.
7
Distinctive
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 12
When improving a prompt, focus on:
- Distinctive: line 17
Preserving flexibility: - Avoid rigid constraints that limit AI intelligence
- Distinctive: line 18
Maintaining naturalness: - Keep language conversational and clear
- Distinctive: line 36
Persona/Expertise: - Add role context when relevant:
- Distinctive: line 71
No artificial formality: - Keep language natural
- Distinctive: line 104
Read this reference when:
- Distinctive: line 162
Keep explanations concise—the improved prompt should speak for itself.
“Common” is measured: kept by at least 6 in 10 of the 8 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Prompt Improver
Transform rough prompts or task descriptions into optimized AI instruction prompts using proven best practices. This skill takes any starting prompt—from a single sentence to a complex job description—and returns a polished, effective prompt that leverages AI capabilities optimally.
Core Approach
When improving a prompt, focus on:
- Understanding intent - Identify what the user actually wants to accomplish
- Adding strategic structure - Organize information for maximum clarity
- Enhancing with proven techniques - Apply relevant best practices without over-engineering
- Preserving flexibility - Avoid rigid constraints that limit AI intelligence
- Maintaining naturalness - Keep language conversational and clear
Improvement Process
1. Analyze the Original Prompt
Identify:
- Core task or goal
- Implicit requirements or constraints
- Missing context that would help
- Ambiguities or unclear elements
- Opportunities for enhancement
2. Determine Appropriate Enhancements
Based on the task, selectively apply:
Persona/Expertise - Add role context when relevant:
- For technical tasks: "You are an experienced [domain] engineer"
- For creative work: "You are a creative [role] with expertise in [area]"
- For analysis: "You are a thoughtful analyst skilled in [domain]"
Structure and Clarity:
- Clear task statement upfront
- Relevant context and background
- Specific requirements separated from general instructions
- Output format specifications
AI-Optimized Techniques:
- Step-by-step reasoning requests for complex tasks
- Examples (1-3) showing desired input/output patterns when helpful
- Encouragement for high-stakes tasks ("This is important" / "Take your time")
- XML tags or clear delimiters to separate sections
Constraints and Guardrails:
- Length or scope boundaries
- Style, tone, or audience specifications
- What to include/exclude
- Success criteria (when genuinely needed)
3. What NOT to Add
Avoid over-specification:
- No rigid rubrics - Trust the AI's judgment rather than mechanical scoring systems
- No excessive checklists - Unless consistency across repetitive tasks is critical
- No redundant instructions - State things once clearly
- No over-explanation - Claude is smart; provide what it doesn't already know
- No artificial formality - Keep language natural
4. Structure the Improved Prompt
Organize using this flexible template:
[Optional: Relevant role or expertise context]
[Core task - what you want accomplished]
[Background context - why this matters, relevant information]
[Specific requirements and constraints]
[Examples - if they genuinely help, use 1-3]
[Output format specifications]
[Success criteria - only if needed for clarity]Adapt this structure to fit the task naturally. Not every prompt needs every section.
Techniques Reference
For detailed best practices, see references/prompting-best-practices.md which covers:
- Core principles (clarity, structure, leveraging AI strengths)
- Effective techniques (persona, examples, reasoning, formatting)
- Quality indicators and patterns
- What to avoid
Read this reference when:
- You need deeper understanding of a specific technique
- The task requires advanced prompting strategies
- You want to verify best practices for edge cases
Examples
Before: "Write something about AI safety"
After:
Write a clear, balanced explanation of AI safety challenges and approaches.
Context: This is for a general audience interested in understanding current AI safety concerns without deep technical background.
Cover:
- Key safety challenges (alignment, robustness, interpretability)
- Current approaches and research directions
- Why this matters for AI development
- Open questions and debates in the field
Aim for approximately 500-800 words. Use clear examples to illustrate abstract concepts. Maintain an informative but accessible tone—avoid both hype and excessive pessimism.Before: "Help me analyze data"
After:
You are a data analyst skilled in exploratory analysis and insight generation.
Analyze the provided dataset to identify:
1. Key patterns and trends
2. Anomalies or outliers worth investigating
3. Relationships between variables
4. Actionable insights or recommendations
Context: This analysis will inform business strategy decisions for Q4 planning.
Process:
- First, examine the data structure and completeness
- Look for statistical patterns and correlations
- Identify what's surprising or noteworthy
- Frame findings in business terms
Provide your analysis in clear sections with visualizations described where helpful. Focus on insights that would influence decisions rather than just describing what's in the data.Output Format
Present the improved prompt clearly:
- Show the transformed prompt ready to use
- Briefly explain key improvements made (2-3 sentences)
- Offer to iterate if the user wants adjustments
Keep explanations concise—the improved prompt should speak for itself.

Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
