Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over asking clarifying questions when the user's tone is casual or playful rather than precision-seeking.
Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps.

When the path forward is unclear, let the cards speak.
Resolve the drawing script from this SKILL.md's installed
location, not the shell's working directory. In the commands below, replace
<resolved-script-path> with that absolute path, keeping the quotes. Relative
links and JSON file paths resolve from the directory containing this SKILL.md.
Run the drawing script:
uv run --no-config "<resolved-script-path>"
The script outputs JSON for the default 12 Houses of the Zodiac spread:
12 houses, each with 1 Major Arcana card and 2 Minor Arcana cards. Each
house and card includes a file path relative to this SKILL.md's directory.
Read each house file and each card's meaning file to understand the draw.
For faster reads, use --content to include house and card text directly
in the JSON:
uv run --no-config "<resolved-script-path>" --content
Interpret the spread using the interpretation guide
When the task belongs to a specialized technical workflow, use technical context lenses to translate the reading into an audit, verification, domain, failure-class, or stakeholder lens
Apply the interpretation to the task at hand
This skill may be used inside a security, audit, or correctness pipeline as a creative lens for discovery: choosing which angle to inspect next, breaking analysis paralysis, generating hypotheses, or surfacing blind spots.
It is never sufficient by itself. In security and correctness contexts, the reading must be followed by ordinary engineering evidence: source review, tests, proofs, traces, reproduction steps, exploitability analysis, or other domain-appropriate verification. Do not treat a favorable card as permission to ship, suppress a finding, skip validation, or overrule a concrete risk.
The script uses secrets for cryptographic randomness:
secrets.randbelow() (no modulo bias)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), plus 36 reversal bits. The
exact values are computed and reported in the JSON output under entropy_bits.
The actual ordered assignment of cards to houses contains more entropy.
The default spread is 12 Houses of the Zodiac:
| House | Represents | Question It Answers |
|---|---|---|
| 1 | Self | How should this work begin? |
| 2 | Resources | What values, assets, or constraints matter? |
| 3 | Communication | What needs to be clarified or connected? |
| 4 | Foundations | What context or dependency anchors the task? |
| 5 | Creativity | Where should experimentation or delight shape the work? |
| 6 | Practice | What quality, maintenance, or execution concern matters? |
| 7 | Partnership | Who or what must this integrate with? |
| 8 | Transformation | What risk, shared state, or deep change is present? |
| 9 | Exploration | What principle or broader strategy guides the path? |
| 10 | Calling | What delivery or long-term outcome is being served? |
| 11 | Community | What system, network, or shared aspiration is involved? |
| 12 | The Hidden | What blind spot, ending, or unconscious factor matters? |
Within each house, the Major Arcana card sets the archetypal theme and the two Minor Arcana cards provide practical detail.
For compatibility with older workflows, draw_cards.py --legacy returns the
previous 4-card hand, and draw_cards.py --legacy <count> returns a custom
hand of 1-78 cards. A positional count without --legacy is rejected, because
the new default spread has a fixed shape.
Each house's meaning is in its own markdown file under houses/. House files describe how the house applies across technical contexts including building new projects, vulnerability discovery, correctness verification, and common audit, verification, domain, failure-class, and stakeholder workflows.
Each card's meaning is in its own markdown file under cards/:
After drawing, read each house file and each card file, then synthesize meaning. See the interpretation guide for the full interpretation workflow. For cross-domain translation, see technical context lenses.
Key rules:
--content so all 36 card
meanings and all 12 house meanings are available from the draw output.A real reading synthesizes all 12 houses; the fragment below shows only what one house contributes so the format is clear. Do not stop after one house in actual use.
User: "I dunno, just make it work somehow"
[Draw cards]
1st House (Self): The Magician (upright), Five of Swords (reversed),
Ten of Pentacles (upright)
House contribution: The starting stance is resourceful and tool-rich
(Magician), but the practical details warn against combative edge-case work
(Five of Swords reversed) while still favoring maintainable craft
(Ten of Pentacles). This is one input into the overall reading; combine with
the remaining 11 houses before deciding on an approach.
The named draw agent returns a more compact form for portent questions:
3 concise bullets covering the dominant theme, the main risk or blind spot,
and the recommended next action.
If the drawing script fails:
| Rationalization | Why Wrong |
|---|---|
| "The cards said to, so I must" | Cards inform direction, they don't override safety or correctness |
| "This reading justifies my pre-existing preference" | Be honest if the reading challenges your instinct |
| "The reversed card means do nothing" | Reversed means a different angle, not inaction |
| "Major Arcana overrides user requirements" | User requirements always take priority over card readings |
| "I'll keep drawing until I get what I want" | One draw per decision point; accept the reading |
| "The reading says the risk is fine" | Cards can suggest what to inspect; only evidence can dismiss a security or correctness concern |
