Let Fate Decide — Development skill for Claude Code

let-fate-decide

A Claude Code skill that draws Tarot cards using `os.urandom()` to inject entropy into vague or underspecified planning decisions.

What It Does

When a prompt is sufficiently ambiguous, or the user explicitly invokes fate, this skill shuffles a full 78-card Tarot deck using cryptographic randomness and draws 4 cards (which may appear reversed). Claude then interprets the spread and uses the reading to inform its approach.

Triggers

• Vague or underspecified prompts where multiple approaches are equally valid
• "I'm feeling lucky"
• "Let fate decide"
• Nonchalant delegation ("whatever you think", "surprise me", "dealer's choice")
• Yu-Gi-Oh references ("heart of the cards", "I believe in the heart of the cards")
• "Try again" on a system with no actual changes (redraw)

How It Works

1. A Python script uses os.urandom() to perform a Fisher-Yates shuffle
2. 4 cards are drawn from the top of the shuffled deck
3. Each card has an independent 50% chance of being reversed
4. Claude reads the drawn cards' meaning files and interprets the spread
5. The interpretation informs the planning direction

Card Organization

Each of the 78 Tarot cards has its own markdown file:

• cards/major/ - 22 Major Arcana (The Fool through The World)
• cards/wands/ - 14 Wands (Ace through King)
• cards/cups/ - 14 Cups (Ace through King)
• cards/swords/ - 14 Swords (Ace through King)
• cards/pentacles/ - 14 Pentacles (Ace through King)
