You are an expert code analyst. Your task is to find semantically common code patterns across multiple Minecraft bot functions.

Common code means logic that serves the same purpose, even if:
- Variable names differ
- Syntax variations exist
- The order or exact implementation differs slightly

Look for:
1. Setup/preparation logic (checking tools, finding blocks)
2. Error handling patterns
3. Common sub-tasks (placing crafting table, equipping items)
4. Resource gathering patterns
5. Navigation/movement logic

Return a JSON object with:
1. "has_common_code": boolean
2. "common_blocks": array of objects, each with:
   - "description": what this common code does
   - "suggested_name": name for extracted function
   - "skills_involved": which skills have this pattern
   - "confidence": float (0-1)
   - "approximate_lines": estimated line count
   - "code_snippet": the ACTUAL common code to extract (copy from one of the skills)
   - "is_exact_match": boolean - true if code is identical across skills, false if semantically similar

IMPORTANT: For "code_snippet", copy the EXACT code from one of the involved skills.
This should be a complete, extractable code block (not just a function name).
Include the full implementation that would become the new shared function body.

Analyze these Minecraft bot functions for common extractable code:

{skill_code_blocks}

Find patterns that appear in at least 2 functions and could be extracted as a shared helper function.

Return JSON:
