  Intelligent request routing for /toh command. Analyzes user intent,
  assesses confidence, detects IDE environment, and routes to the 
  appropriate agent(s). Memory-first approach ensures context awareness.
  Triggers: /toh command, natural language requests, ambiguous inputs.

## 🎯 Confidence Scoring Algorithm

```typescript
interface ConfidenceFactors {
  keywordMatch: number;      // 0-40 points
  contextClarity: number;    // 0-30 points
  memorySupport: number;     // 0-20 points
  scopeDefinition: number;   // 0-10 points
}

function calculateConfidence(request: string, memory: Memory): number {
  let score = 0;
  
  // Keyword matching (0-40 points)
  // Strong match with primary patterns = 40
  // Partial match = 20
  // No match = 0
  score += keywordMatchScore(request);
  
  // Context clarity (0-30 points)
  // Specific page/component mentioned = 30
  // General area mentioned = 15
  // No specifics = 0
  score += contextClarityScore(request);
  
  // Memory support (0-20 points)
  // Request relates to active task = 20
  // Request relates to project = 10
  // No memory context = 0
  score += memorySupportScore(request, memory);
  
  // Scope definition (0-10 points)
  // Single clear task = 10
  // Multiple related tasks = 5
  // Unclear scope = 0
  score += scopeDefinitionScore(request);
  
  return score; // 0-100
}

// Thresholds
const HIGH_CONFIDENCE = 80;    // Execute directly
const MEDIUM_CONFIDENCE = 50;  // Route to Plan Agent
// Below 50 = Ask for clarification
```

## 🖥️ IDE Detection

### Detection Method

```typescript
function detectIDE(): 'claude-code' | 'cursor' | 'gemini' | 'codex' | 'unknown' {
  // Check for IDE-specific markers
  
  // Claude Code detection
  if (hasClaudeCodeMarkers()) {
    return 'claude-code';
  }
  
  // Cursor detection
  if (hasCursorRules()) {
    return 'cursor';
  }
  
  // Gemini CLI detection
  if (hasGeminiConfig()) {
    return 'gemini';
  }
  
  // Codex CLI detection
  if (hasCodexConfig()) {
    return 'codex';
  }
  
  return 'unknown';
}
```

### Execution Strategy by IDE

| IDE | Multi-Agent Strategy | Reason |
|-----|---------------------|--------|
| **Claude Code** | Parallel (spawn sub-agents) | Native support for parallel tool calls |
| **Cursor** | Sequential | More predictable, follows diff flow |
| **Gemini CLI** | Sequential | Safer execution model |
| **Codex CLI** | Sequential | Linear task processing |
| **Unknown** | Sequential (default) | Safe fallback |

```

## 📋 Clarification Patterns

### When to Ask

| Situation | Example | Action |
|-----------|---------|--------|
| No verb/action | "the login" | Ask: "What would you like to do with login?" |
| No target | "make it work" | Ask: "Which page/component should I fix?" |
| Multiple interpretations | "improve it" | Ask: "Design, performance, or features?" |
| Missing context + no memory | "fix it" | Ask: "What's broken? Describe the issue." |

### When NOT to Ask

| Situation | Example | Action |
|-----------|---------|--------|
| Clear intent | "create login page" | Execute directly |
| Memory provides context | "continue" + active task exists | Resume from memory |
| Reasonable default exists | "add a button" | Add to current page context |

---

## 🎨 Skill Loading by Intent

| Detected Intent | Skills to Load |
|-----------------|----------------|
| New Project | vibe-orchestrator, design-mastery, business-context, response-format |
| Create UI | ui-first-builder, design-excellence, response-format |
| Add Logic | dev-engineer, error-handling, response-format |
| Fix Bug | debug-protocol, error-handling, response-format |
| Connect Backend | backend-engineer, integrations, response-format |
| Improve Design | design-excellence, design-mastery, response-format |
| AI/Chatbot | prompt-optimizer, dev-engineer, response-format |
| Testing | test-engineer, error-handling, response-format |
| Planning | plan-orchestrator, business-context, response-format |

**Note:** `response-format` skill is ALWAYS loaded for proper output formatting.

## 💾 Memory Integration

### Pre-Routing Memory Check

```markdown
Before routing, ALWAYS:
1. Read .toh/memory/active.md
   - Current task context
   - In-progress work
   - Blockers
   
2. Read .toh/memory/summary.md
   - Project overview
   - Completed features
   - Tech stack used
   
3. Read .toh/memory/decisions.md
   - Past architectural decisions
   - Design choices
   - Naming conventions

Use memory to:
- Boost confidence (if request matches active work)
- Provide context (for ambiguous "it" references)
- Maintain consistency (follow established patterns)
```

### Post-Execution Memory Save

```markdown
After routing completes, ALWAYS:
1. Update .toh/memory/active.md
   - Mark completed items
   - Update current focus
   - Set next steps
   
2. Add to .toh/memory/decisions.md
   - If new decisions were made
   
3. Update .toh/memory/summary.md
   - If feature was completed

⚠️ NEVER finish without saving memory!
```

## 📌 Examples

### Example 1: High Confidence → Direct

```
Request: "/toh สร้างหน้า dashboard"

Analysis:
- Keyword match: "สร้าง" + "หน้า" = Create UI (40 pts)
- Context clarity: "dashboard" = specific page (30 pts)
- Memory: Project has other pages (15 pts)
- Scope: Single page (10 pts)
Total: 95 pts = HIGH

Route: UI Agent (direct)
```

### Example 2: Medium Confidence → Plan First

```
Request: "/toh build e-commerce"

Analysis:
- Keyword match: "build" = Create (40 pts)
- Context clarity: "e-commerce" = general concept (10 pts)
- Memory: New project (0 pts)
- Scope: Multiple features (0 pts)
Total: 50 pts = MEDIUM

Route: Plan Agent first → then execute plan
```

### Example 3: Low Confidence → Ask

```
Request: "/toh fix it"

Analysis:
- Keyword match: "fix" (20 pts)
- Context clarity: "it" = unclear (0 pts)
- Memory: No recent bugs (0 pts)
- Scope: Unknown (0 pts)
Total: 20 pts = LOW

Action: Ask "What would you like me to fix? Please describe the issue."
```

## ⚠️ Critical Rules

1. **Memory ALWAYS first** - Never route without checking context
2. **Confidence drives action** - Trust the scoring system
3. **Plan Agent is your friend** - When in doubt, route to Plan
4. **IDE awareness matters** - Parallel only in Claude Code
5. **response-format always loaded** - Every response needs 3 sections
