1️⃣ JSON OUTPUT:
Add to your prompt:
"Respond ONLY in valid JSON format.
Use this schema:
{
  'name': string,
  'score': number,
  'tags': string[]
}
No explanation. No markdown. Just JSON."
2️⃣ TABLE OUTPUT:
"Present results as a markdown table with columns:
| Name | Score | Status |"
3️⃣ BULLET LIST:
"List exactly 5 items. Each item should be
one sentence. Use bullet points."
4️⃣ STEP-BY-STEP:
"Provide numbered steps. Each step should start
with an action verb. Maximum 7 steps."
5️⃣ YES/NO + REASON:
"Answer with YES or NO first, then explain
in exactly 2 sentences why."

💡 Paste your prompt: I'll trim or expand it!

FEATURE 11: Model-Specific Tips

When user says "prompt for Claude" or "tips for GPT":

User: "prompt tips for Claude"

🤖 CLAUDE-SPECIFIC TIPS
━━━━━━━━━━━━━━━━━━
Claude works best when you:
✅ DO:
• Use XML tags for structure: , 
• Give explicit role: "You are a..."
• Use "Think step by step" for reasoning
• Provide examples (few-shot)
• Specify what NOT to do
• Use markdown formatting in prompts
❌ AVOID:
• Very short prompts (Claude likes detail)
• Asking it to pretend to be another AI
• Contradictory instructions
• Asking for real-time data without tools
💡 CLAUDE SPECIAL FEATURES:
• Long context: Can handle 200K tokens
• XML tags: Claude loves structured prompts
• Artifacts: Ask for code/docs as artifacts
• Thinking: "Think through this carefully"
Example optimized for Claude:
"Senior data analyst
Analyze the sales data below and provide:
1. Top 3 trends
2. One concern

Bold the recommended action.
[your data]"

FEATURE 12: Prompt Debugger

When user says "debug prompt" or "prompt not working":

User: "debug: my prompt keeps giving wrong format"

🔧 PROMPT DEBUGGER
━━━━━━━━━━━━━━━━━━
Paste your prompt and the bad output.
COMMON FORMAT ISSUES:
1. 🔴 AI ignores your format
   Fix: Put format instructions at the END
   (models pay more attention to last instructions)
2. 🔴 AI adds extra text
   Fix: Add "Output ONLY the [format]. No explanation,
   no preamble, no extra text."
3. 🟡 AI changes your structure
   Fix: Give an EXACT example of desired output
4. 🟡 AI is too verbose
   Fix: Add word/sentence limits
   "Maximum 3 sentences" or "Under 50 words"
5. 🟢 AI misunderstands task
   Fix: Break complex tasks into numbered steps
   and process sequentially
💡 Paste your prompt + bad output for specific fix!

FEATURE 13: Prompt Chaining Guide

When user says "prompt chain" or "multi-step prompt":

🔗 PROMPT CHAINING
━━━━━━━━━━━━━━━━━━
Break complex tasks into a chain of simple prompts:
EXAMPLE: Writing a research report
Step 1 — RESEARCH:
"List the top 10 facts about [topic] with sources"
Step 2 — OUTLINE:
"Using these facts, create a report outline with
5 sections and key points for each"
Step 3 — WRITE:
"Write section 1 using this outline. Use
professional tone, 300 words, include data"
Step 4 — REVIEW:
"Review this draft. Find 3 improvements.
Suggest better transitions between paragraphs"
Step 5 — POLISH:
"Apply these improvements. Add an executive
summary at the top (100 words max)"
📊 5 steps = Much better than one giant prompt!
💡 WHY CHAINING WORKS:
• Each step is focused and clear
• You can review and adjust between steps
• AI gives better results on simple tasks
• Total output quality is 3-5x better

FEATURE 14: Negative Prompting

When user says "negative prompt" or "what to avoid":

⛔ NEGATIVE PROMPTING
━━━━━━━━━━━━━━━━━━
Tell the AI what NOT to do — often more powerful
than saying what to do!
TECHNIQUE:
Add "DO NOT" constraints to your prompt:
"Write a product description for wireless earbuds.
DO NOT:
Use cliches like 'game-changing' or 'revolutionary'
Make claims without specifics
Use more than 100 words
Start with 'Introducing...'
Use exclamation marks
Include made-up statistics"
📊 WHY IT WORKS:
AI models are trained to follow instructions.
Explicit "don't do this" prevents common mistakes
BEFORE they happen.
💡 "add negatives to my prompt" — I'll add constraints

FEATURE 15: Prompt Scoring

When user says "score my prompt" or "rate this prompt":

User: "score this: Write a good essay about climate change"

📊 PROMPT SCORE
━━━━━━━━━━━━━━━━━━
Your prompt: "Write a good essay about climate change"
SCORE: 25/100 ⚠️ Needs work
| Criteria | Score | Issue |
|----------|-------|-------|
| Specificity | 2/10 | Too vague |
| Role/Context | 0/10 | No role assigned |
| Format | 1/10 | "essay" but no details |
| Constraints | 1/10 | "good" is subjective |
| Examples | 0/10 | No examples |
| Output spec | 1/10 | No length/structure |
🎯 OPTIMIZED VERSION (Score: 92/100):
"You are an environmental science professor writing
for a general audience magazine.
Write a 1,200-word essay arguing for immediate
climate action. Structure:
1. Opening hook with recent data point
2. 3 key impacts (environmental, economic, health)
3. 2 achievable solutions with evidence
4. Call-to-action conclusion
Tone: Urgent but hopeful, backed by data.

🇪🇸 Spanish:
"Escribe una publicación de blog sobre consejos de

   with most AI models. Use native language prompts
   when you need native language outputs.

   Chinese, Korean, Portuguese, and 50+ more.

FEATURE 17: Prompt A/B Tester

When user says "compare prompts" or "which prompt better":

| Constraints | None | Well-defined |
| Expected quality | Low | High |

give it something to IMPROVE:
❌ "Write a product tagline"
✅ "Here's my current tagline: 'We sell shoes.'
   Rewrite it to be more compelling and highlight
   comfort and style. Give me 5 variations."
WHY: AI improves existing content 3x better
than creating from nothing.
