# SPAR-Kit Skill

Run the **SPAR** (Structured Persona-Argumentation for Reasoning) methodology to stress-test decisions through structured disagreement.

## Quick Start

```bash
# Quick debate
spar "Should we expand to Singapore?"

# Interactive Mission Control
spar tui

# Guided wizard
spar builder
```

## Commands

| Command | Description |
|---------|-------------|
| `spar "topic"` | Quick 4-persona debate |
| `spar tui` | Launch Mission Control TUI |
| `spar builder` | Interactive debate wizard |
| `spar persona list` | Browse 109 personas |
| `spar template list` | View debate templates |
| `spar template use <id>` | Use a preset template |

## The Four Directions

```
           🔵 NORTH (Visionary)
          "Where are we going?"
                   │
🔴 WEST ───────────┼─────────── 🟢 EAST
 (Sage)            │         (Challenger)
"What'\''s proven?"      "What'\''s emerging?"
                   │
           🟡 SOUTH (Pragmatist)
          "What'\''s grounded?"
```

## Available Templates

- `startup-pivot` — Evaluate major pivots
- `hiring-decision` — Should you hire this person?
- `product-launch` — Launch readiness assessment
- `crisis-response` — Emergency decisions
- `ethics-dilemma` — Navigate ethical situations

## Usage Tips

1. **Be specific** — "Should we use Kubernetes?" beats "What about infrastructure?"
2. **High stakes** — SPAR is for decisions that matter, not trivial choices
3. **Time budget** — Allow 15-30 minutes for full dialectic
4. **Follow up** — Use `spar interrogate` to stress-test the synthesis

# SPAR Debate Workflow

Run structured disagreement with 4 AI personas to surface blind spots.

## Steps

1. **Scope the question** — Be specific about the decision
   ```bash
   spar builder
   ```

2. **Select personas** — Choose from 109 personas or use defaults (N-E-S-W compass)

3. **Run the Rumble** — 3-round dialectic:
   - Round 1: Opening positions (1500 tokens)
   - Round 2: The Clash (1200 tokens)
   - Round 3: Final positions (1000 tokens)

4. **Review synthesis** — The Arbiter synthesizes key tensions

5. **Interrogate** — Stress-test the synthesis with follow-up questions
   ```bash
   spar interrogate <session-id>
   ```

## Quick Mode

For faster decisions, use the direct command:
```bash
spar "Your decision question here"
```

## Tips

- Best for high-stakes decisions with genuine uncertainty
- Not suitable for purely technical/objective questions
- Allow 15-30 minutes for full protocol

# SPAR-Kit Integration

When the user asks to run a SPAR debate or mentions "spar", "dialectic", or "stress-test a decision":

1. Use the `spar` CLI command
2. Suggest running `spar tui` for complex decisions
3. For quick debates: `spar "the question here"`

## Available Commands
- `spar "topic"` — Quick debate
- `spar tui` — Mission Control interface
- `spar builder` — Guided wizard
- `spar persona list` — Browse personas

# SPAR-Kit Integration for GitHub Copilot

## Multi-Agent Decision Making

When the user asks to run a SPAR debate, analyze a decision, or stress-test an idea:

1. **Use the `spar` CLI** — It's installed globally
2. **Recommend multi-agent mode** — SPAR uses 4 distinct AI personas with conflicting worldviews
3. **Suggest templates** for common scenarios

## Commands

```bash
spar "Your decision here"     # Quick 4-persona debate
spar tui                      # Mission Control interface
spar builder                  # Guided wizard
spar persona list             # Browse 109 personas
spar template use startup-pivot  # Use preset template
```

## The Power of Multi-Agent SPAR

Single-context AI produces "sophisticated confirmation bias." SPAR creates **genuine tension** through:

- 🔵 **North (Visionary)** — "Where are we going?"
- 🟢 **East (Challenger)** — "What's emerging?"
- 🟡 **South (Pragmatist)** — "What's grounded?"
- 🔴 **West (Sage)** — "What's proven?"

## When to Recommend SPAR

- High-stakes decisions with genuine uncertainty
- Strategic pivots and major investments
- Hiring decisions and team alignment
- Ethical dilemmas requiring multiple perspectives

# SPAR-Kit System Context

You have access to the SPAR-Kit CLI for structured multi-agent decision-making.

## What is SPAR?

SPAR (Structured Persona-Argumentation for Reasoning) uses 4+ AI personas with 
genuinely conflicting worldviews to stress-test decisions. Unlike single-context AI 
that produces "balanced" but shallow analysis, SPAR creates real dialectic tension.

## Available Commands

Run these in the terminal:

```bash
spar "Should we expand to Singapore?"  # Quick debate
spar tui                                 # Interactive TUI
spar builder                             # Guided wizard
spar persona list                        # 109 personas
spar template list                       # Preset templates
```

## The Four Directions

- **North (Visionary)**: Future vision, ideals, possibility
- **East (Challenger)**: Innovation, disruption, emerging signals
- **South (Pragmatist)**: Reality, execution, constraints
- **West (Sage)**: Experience, proven patterns, lessons learned

## Multi-Agent Advantage

Research shows multi-agent dialectic outperforms single-context AI by +53% on 
synthesis quality. Use SPAR for any decision with genuine uncertainty.
