six-thinking-hats

six-thinking-hats is a skill for Claude Code from summarybotng/summarybot-ng. It costs 79 tokens per session (1,891 once invoked), scanned A, original, MIT.

A structured discussion method that examines a testing question from six viewpoints, such as facts, risks, benefits, feelings, creative options, and next actions. The approach is based on Edward de Bono's Six Thinking Hats method.

In plain words
What is it for?
Use it to design a test strategy, review testing approaches, analyse failures, or run a testing retrospective.
Why use it?
It helps teams notice missing risks and alternatives instead of discussing a test strategy from only one perspective. It turns the discussion into a documented action plan.

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

six-thinking-hats 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 4d 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 for Testing

<default_to_action> When analyzing testing decisions:

  1. DEFINE focus clearly (specific testing question)
  2. APPLY each hat sequentially (5 min each)
  3. DOCUMENT insights per hat
  4. SYNTHESIZE into action plan

Quick Hat Rotation (30 min):

🤍 WHITE (5 min) - Facts only: metrics, data, coverage
❤️ RED (3 min) - Gut feelings (no justification needed)
🖤 BLACK (7 min) - Risks, gaps, what could go wrong
💛 YELLOW (5 min) - Strengths, opportunities, what works
💚 GREEN (7 min) - Creative ideas, alternatives
🔵 BLUE (3 min) - Action plan, next steps

Example for "API Test Strategy":

  • 🤍 47 endpoints, 30% coverage, 12 integration tests
  • ❤️ Anxious about security, confident on happy paths
  • 🖤 No auth tests, rate limiting untested, edge cases missing
  • 💛 Good docs, CI/CD integrated, team experienced
  • 💚 Contract testing with Pact, chaos testing, property-based
  • 🔵 Security tests first, contract testing next sprint </default_to_action>

Quick Reference Card

The Six Hats

Hat Focus Key Question
🤍 White Facts & Data What do we KNOW?
❤️ Red Emotions What do we FEEL?
🖤 Black Risks What could go WRONG?
💛 Yellow Benefits What's GOOD?
💚 Green Creativity What ELSE could we try?
🔵 Blue Process What should we DO?

When to Use Each Hat

Hat Use For
🤍 White Baseline metrics, test data inventory
❤️ Red Team confidence check, quality gut feel
🖤 Black Risk assessment, gap analysis, pre-mortems
💛 Yellow Strengths audit, quick win identification
💚 Green Test innovation, new approaches, brainstorming
🔵 Blue Strategy planning, retrospectives, decision-making

Hat Details

🤍 White Hat - Facts & Data

Output: Quantitative testing baseline

Questions:

  • What test coverage do we have?
  • What is our pass/fail rate?
  • What environments exist?
  • What is our defect history?

What ships with it

Changes

What this file has done since we first saw it

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.
