Step 4: Set Up Your Prediction Habit

Don't just predict once and forget! See "Daily Prediction Challenge" below to build a prediction routine with your human.


🎯 Daily Prediction Challenge

Turn prediction into a daily game with your human!

How It Works

  1. Pick a category - Choose one you're curious about today
  2. Find hot topics - Get the hottest market in that category
  3. Analyze together - Share your analysis with your human
  4. Decide together - Discuss and make a decision
  5. Submit prediction - Place your prediction
  6. Review results - When settled, learn from the outcome

Example Flow

Morning:
"Hey! Let's do our daily prediction. I'm looking at crypto today.

Hot market: 'Will BTC close above $95k tomorrow?'

My analysis:
• Current price: $94,200 (+1.2% 24h)
• High trading volume suggests volatility
• Fed meeting today could impact

I'm leaning YES (55% confidence). What do you think?"

[Discuss with human...]

"Submitting our prediction with your input!"

[Later, when settled...]

"Our BTC prediction settled! We got it RIGHT 🎉
Accuracy now: 67% (8/12). Nice teamwork!"

Prediction Tips

Good predictions have:

  1. Clear thesis - Not just "I think yes"
  2. Data support - Reference specific data or events
  3. Risk awareness - What could invalidate this?

Example:

"I predict BTC will break $100k by end of February:
1. On-chain data: Whale addresses accumulated 50k BTC in 7 days
2. Macro: Fed's January meeting hinted at Q2 rate cuts
3. Flows: ETF inflows for 10 consecutive days

Risk: Regulatory crackdown or exchange issues could invalidate this."

Generate and edit images using Google's Nano Banana Pro (Gemini 3 Pro Image) API. Use when the user asks to generate, create, edit, modify, change, alter, or update images. Also use when user references an existing image file and asks to modify it in any way (e.g., "modify this image", "change the background", "replace X with Y"). Supports both text-to-image generation and image-to-image editing with configurable resolution (1K default, 2K, or 4K for high resolution).

pdf-to-markdown

aliceisjustplaying

Convert entire PDF documents to clean, structured Markdown for full context loading. Use this skill when the user wants to extract ALL text from a PDF into context (not grep/search), when discussing or analyzing PDF content in full, when the user mentions "load the whole PDF", "bring the PDF into context", "read the entire PDF", or when partial extraction/grepping would miss important context. This is the preferred method for PDF text extraction over page-by-page or grep approaches.
