sixhats

sixhats is a skill for Claude Code from askarzh/epistemator. It costs 80 tokens per session (1,883 once invoked), scanned A, original, MIT.

A way to organize group or individual thinking by considering one mode at a time: facts, feelings, criticism, optimism, creativity, and process. It is based on Edward de Bono's Six Thinking Hats method.

In plain words
What is it for?
Use it for decisions, evaluations, planning, and situations where you want to consider facts, feelings, risks, benefits, new ideas, and next steps separately.
Why use it?
People often mix evidence, emotions, criticism, and ideas together, making decisions harder to assess. Separating these viewpoints makes gaps and competing perspectives easier to see.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sixhats scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Six Thinking Hats (De Bono)

Overview

Apply Edward de Bono's Six Thinking Hats method — a structured parallel thinking framework that separates thinking into six distinct modes, each represented by a colored hat. By wearing one hat at a time, thinkers avoid the confusion of mixing facts with emotions, criticism with creativity, and analysis with action.

This is a thinking organization tool, not a truth-finding or analytical framework. It does not determine what is true (use Scholastic for that) or decompose complexity (use Cartesian for that). Its power is in ensuring that all relevant cognitive modes — factual, emotional, critical, optimistic, creative, procedural — are exercised deliberately rather than haphazardly. The output is a structured map of perspectives, not a resolved conclusion.

The Six Hats method excels at decisions, evaluations, planning, and any input where multiple perspectives need to be explored without the chaos of unstructured debate.

The Six Hats

Hat Focus Key Question
White — Facts Objective data, information, what is known and what is missing "What do we know? What do we need to find out?"
🔴 Red — Feelings Intuitions, emotions, gut reactions — no justification required "What is my gut feeling about this?"
Black — Caution Risks, dangers, problems, weaknesses, why it might fail "What could go wrong?"
🟡 Yellow — Optimism Benefits, value, feasibility, why it might work "What are the benefits? Why is this worth doing?"
🟢 Green — Creativity Alternatives, new ideas, possibilities, provocations, modifications "What are the alternatives? What new ideas emerge?"
🔵 Blue — Process Meta-thinking, organization, summary, conclusions, next steps "What have we learned? What should we do next?"

Core Methodology

  1. 🔵 Blue Hat Opening — Define the focus. What is the topic, question, or decision? What outcome is needed? Set the sequence of hats to use. The default order below (White → Red → Black → Yellow → Green) works for most situations, but adapt it: start with Red if emotions are running high and need acknowledgment first; start with Black if the proposal seems risky and caution is the priority; skip Green if no alternatives are needed.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
