The skill content is untouched since 2026-01-29. The only commits to the directory since were repo-wide sweeps (formatting in #98, codex UI metadata in #175), not maintenance. It also spends a lot of context on something you can get from one English sentence to Claude. Asking clarifying questions when a request is ambiguous is native Claude Code behaviour now, through AskUserQuestion, so an 86-line skill that mostly explains how to format multiple-choice options is paying context for a built-in. Knock-on edits: AGENTS.md used this plugin as its Basic reference example, now git-cleanup, which is a better fit anyway at five files and one self-contained SKILL.md. let-fate-decide pointed at the skill by name in its description and its When NOT to Use list, now reworded to plain "ask clarifying questions"; its description feeds skill triggering, so it gets a patch bump to 1.2.2.

let-fate-decide
A Claude Code skill that draws Tarot cards using secrets 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 22-card Major Arcana deck and a 56-card Minor Arcana deck independently using cryptographic randomness, then deals the 12 Houses of the Zodiac spread. Each house receives one Major Arcana card followed by two Minor Arcana cards, and all 36 cards may appear reversed. Claude then interprets the spread and uses the reading to inform its approach.
Triggers
- Vague or ambiguous prompts where multiple reasonable approaches exist
- "I'm feeling lucky", "let fate decide", "dealer's choice", "surprise me", "whatever you think", "YOLO"
- Casual delegation ("whatever", "up to you", "your call", "idk", "just do something", "wing it", "I trust you", "doesn't matter", "do what you want", "I don't care", "any approach works", "you pick")
- Yu-Gi-Oh references ("heart of the cards", "I believe in the heart of the cards", "you've activated my trap card", "it's time to duel")
- Shrug-like brevity -- very short prompts that fully delegate the decision
- About to arbitrarily pick between 2+ valid approaches (draw cards instead)
- "Try again" on a system with no actual changes (redraw)
How It Works
- A Python script uses
secrets.randbelow()to perform Fisher-Yates shuffles - A Major Arcana deck and Minor Arcana deck are shuffled separately
- 12 houses are dealt, each with 1 Major Arcana and 2 Minor Arcana cards
- Each card has an independent 50% chance of being reversed
- Claude reads the house reference files and drawn cards' meaning files
- Claude interprets the spread
- The interpretation informs the planning direction
The default spread records a conservative unordered-card entropy budget
exceeding 100 bits: roughly log2(C(22,12)) bits from Major Arcana selection,
log2(C(56,24)) bits from Minor Arcana selection (assuming
secrets.randbelow() is cryptographically secure), and 36 bits from
independent card reversal choices. Exact values are computed at draw time and
reported in the JSON output under entropy_bits. The actual ordered assignment
of cards to houses contains more entropy.
In security, audit, and correctness workflows, this skill is only a discovery and hypothesis-generation aid. It can suggest where to look next, but evidence from review, testing, reproduction, or formal reasoning must decide whether a risk is real or resolved.
Reference Organization
Each zodiac house has its own markdown file under houses/. These files
explain the house's technical meaning for building new projects, vulnerability
discovery, correctness verification, and recurring workflows from the local
security and engineering workflows this skill supports.
references/TECHNICAL_CONTEXT_LENSES.md distills those workflow themes into
audit-stage, evidence-mode, domain, failure-class, and human/organizational
lenses.
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)
