Will this skill ignore my specific instructions?

No. User requirements always take priority. This skill is only intended for use when prompts are underspecified, when there are multiple valid approaches, or when the user explicitly requests a randomized choice.

Can I use this for security-critical decisions?

No. The skill is explicitly restricted from safety-critical tasks, security audits, or production deployments where data integrity is at stake. It is a tool for creative and technical direction, not a replacement for rigorous engineering.

Is the card drawing process truly random?

Yes. The skill executes a Python script using os.urandom() to ensure high-entropy, cryptographically secure randomness, avoiding the biases of standard pseudo-random number generators.

What is the Let Fate Decide skill?

It is a specialized capability for Claude Code that uses a Tarot-based framework and cryptographic randomness to help the AI choose a path forward when user instructions are vague or ambiguous.

What do the four card positions represent?

The spread covers four distinct areas: The Context (the current situation), The Challenge (the obstacle), The Guidance (the recommended approach), and The Outcome (the projected result of that path).

生産性とワークフロー

Injects cryptographic entropy into development planning using a Tarot-based framework to resolve ambiguity and break decision paralysis.

This skill provides a structured methodology for Claude to handle underspecified or highly ambiguous prompts by performing a 4-card Tarot draw. Utilizing true randomness via os.urandom(), the skill maps archetypal meanings—representing the Context, Challenge, Guidance, and Outcome—to concrete technical decisions. It is designed to assist when multiple valid architectural paths exist or when a user explicitly requests a randomized approach, ensuring the model remains decisive and creative without hallucinating specific user requirements or forcing a biased preference.
