Challenge assumptions with a deterministic thinking partner that applies 150+ mental models like SWOT, first principles, and inversion to structure reasoning, sharpen decisions, and solve complex problems via orientation detection and diagnostic workflows.
npx claudepluginhub mattnowdev/thinking-partnerA deterministic thinking partner that challenges assumptions and applies 150+ mental models to sharpen decisions, solve problems, and think more clearly.
Built on the open Agent Skills standard. Works with Claude Code, Cursor, Windsurf, Cline, GitHub Copilot, and any AI agent that supports the standard.

Not a lecture — a sparring session. Turns your AI agent into a thinking partner that:
| Feature | This Skill | Others |
|---|---|---|
| Orientation Detection | Diagnoses 6 thinking states (GT0-GT5) with targeted interventions | Generic questioning |
| 150+ Mental Models | Full catalog organized by discipline with key questions | Handful of models |
| Cognitive Operations | 7 complementary operation pairs (Decouple/Re-couple, Hold/Resolve, etc.) | None |
| Structured Workflow | 6-step deterministic process from diagnosis to synthesis | Freeform |
| Anti-Patterns | Explicit guidance on what NOT to do | None |
Organized across 17 disciplines:
