# Increment Work Router - Smart Work Continuation

## Purpose

The increment-work-router skill is an **intelligent work continuation system** that:
- ✅ Detects implementation/continuation intent (not just new projects)
- ✅ Checks for active increments automatically
- ✅ Routes to existing increment OR creates new one
- ✅ Bridges the gap between planning and execution

**Key Insight**: When user says "implement X" or "complete Y", they expect the system to handle routing intelligently without manual commands.

## When to Activate

This skill activates when user expresses **implementation/continuation intent**:

### High-Confidence Triggers (Auto-Route)

**Action Verbs** (with specific target):
- "Implement [feature]"
- "Complete [task]"
- "Build [component]"
- "Add [functionality]"
- "Develop [module]"
- "Create [feature]"

**Continuation Phrases**:
- "Work on [feature]"
- "Continue [increment]"
- "Resume [work]"
- "Finish [task]"
- "Let's implement [X]"
- "Let's build [Y]"
- "Start working on [Z]"

**Bug/Fix Intent**:
- "Fix [issue]"
- "Resolve [bug]"
- "Address [problem]"

### Medium-Confidence Triggers (Clarify)

**Vague Intent** (needs target clarification):
- "Let's continue"
- "Keep working"
- "What's next?"
- "Continue where we left off"

### Don't Activate For

**Planning/Discussion** (let other skills handle):
- "What should we build?" → increment-planner
- "How does X work?" → Regular conversation
- "Should we use Y?" → Technical discussion
- "Plan a new feature" → increment-planner

**Already in Workflow**:
- User is already executing `/sw:do`
- Increment planning is in progress
- Another skill is handling the request

## Core Algorithm

### Step 1: Detect Intent

Scan user message for implementation keywords:
```
Action verbs: implement, complete, build, add, develop, create
Continuation: work on, continue, resume, finish, start
Bug/Fix: fix, resolve, address
```

Calculate confidence:
- **High (>80%)**: Action verb + specific target ("implement user auth"
