  Use this skill when the user needs deep analysis of complex problems,
  architecture decisions, debugging difficult issues, or thorough
  evaluation of trade-offs. Activates structured thinking with explicit
  reasoning steps, constraint analysis, and multi-perspective evaluation.
examples:
  - input: "think deeply about microservice vs monolith for our scale"
    action: analyze
  - input: "decompose the authentication flow redesign"
    action: decompose
  - input: "evaluate three caching strategies for our API"
    action: evaluate

# Ultra Think

Extended thinking mode for complex problem solving.

## Usage

```
/ultrathink analyze "<complex problem or decision>"
/ultrathink decompose "<large task or system design>"
/ultrathink evaluate "<options to compare>"
```

## Thinking Modes

- **Analyze**: Deep dive into a single problem with constraint mapping and solution space exploration
- **Decompose**: Break complex tasks into sub-problems with dependency graphs
- **Evaluate**: Multi-criteria comparison of options with trade-off matrices

## Process

1. Problem restatement and clarification
2. Constraint and assumption identification
3. Multi-perspective analysis
4. Solution space exploration
5. Trade-off evaluation
6. Recommendation synthesis
