Ran a real 'should I quit my job for dropshipping' plan through it: baseline gave hedged encouragement, the skill named the planning fallacy driving the plan, costed the avoidance in concrete salary-runway terms, and closed with a forced 2-4-choice question instead of a pep talk.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 9/10
  • Docs & honesty 5/5

What Honest Thinking Partner does

Reframes Claude into a structured 6-step critique partner that audits assumptions, names the specific cognitive bias at play, and ends with a prioritized action plan plus a kill-switch signal instead of generic encouragement. Triggers on requests for brutal honesty, devil's-advocate feedback, or a pasted plan/decision seeking validation; explicitly skips pure information questions with no decision component.
