Focus Problem Analysis

Analyze: $ARGUMENTS

Explore Codebase First

Before diving in, use the Explore agent to understand the context:

Agent(subagent_type="Explore", model="haiku", prompt="""
Explore the codebase for: $ARGUMENTS (thoroughness: medium)
Focus on:
1. Relevant files and modules
2. Existing similar features
3. Test patterns
4. Architecture patterns

Analysis Framework

1. Core Problem Identification

• **What is the real problem?**
• **Why does it need to be solved?**
• **What happens if we don't solve it?**

2. Minimal Solution Scope

• **What's the minimum change needed?**
• **Which features are essential?**
• **What can be deferred or omitted?**

3. Solution Evaluation

• **Option A (Simplest):**
• **Option B (Balanced):**
• **Option C (Complete):**
• **Recommendation:** Choose the simplest viable option

4. Implementation Plan

• **Step 1:** Write tests
• **Step 2:** Minimal implementation
• **Step 3:** Update documentation
• **Step 4:** Commit changes
