Thinking tools: creativity, mental models, cognitive biases, and decision frameworks for any domain
Import solutions from unrelated domains - find unexpected connections between distant fields to solve problems
Quick cognitive bias scan - identify biases that might be affecting a decision or belief
Quick creative brainstorming session - generates 10 ideas on any topic in 60 seconds
Argue the opposite position - build the strongest case against your current thinking
Break a problem down to fundamental truths and rebuild from there - escape conventional thinking
Identifies cognitive biases in thinking and decisions, then provides strategies to overcome them. Use when making important decisions, evaluating plans, or when something "feels off" about reasoning.
Transforms project constraints and limitations into creative opportunities and unique features. Use when facing technical, time, or resource limitations that seem like obstacles.
Breaks creative blocks and generates unconventional ideas through lateral thinking techniques. Use when stuck on a problem, need fresh perspectives, or want to explore unexpected solutions.
Combines disparate concepts, methods, and ideas from different domains into novel solutions. Use when exploring new ideas, looking for unique angles, or wanting to create something that hasn't been done before.
Applies mental models to analyze problems and make better decisions. Use when facing complex decisions, trying to understand systems, or needing structured thinking frameworks.

Plugins can be installed at three different scope levels:
| Scope | Flag | Location | Use Case |
|---|---|---|---|
| User | --scope user | ~/.claude/settings.json | Available in ALL projects |
| Project | --scope project | .claude/settings.json | Shared with team via git |
| Local | --scope local | ~/.claude.json | Current project only (default) |
To use plugins across all your projects, add --scope user:
# Add marketplace globally
claude plugin marketplace add sponticelli/gamedev-claude-plugins --scope user
# Install plugins globally
claude plugin install thinking@gamedev-claude-plugins --scope user
claude plugin install game-design@gamedev-claude-plugins --scope user
claude plugin install strategy@gamedev-claude-plugins --scope user
# ... etc
To share plugins with your team via git:
claude plugin marketplace add sponticelli/gamedev-claude-plugins --scope project
claude plugin install game-design@gamedev-claude-plugins --scope project
Note: If a plugin exists at multiple scopes, local overrides project, which overrides user.
