DRYwall Scan

Scan the codebase for code duplication and present actionable results.

Steps

1. Call the detect_code_duplication MCP tool immediately — do not read any config files or explore the codebase first, the tool handles all configuration automatically. If the user provided arguments, pass them as the options object (converting --min-tokens=50 to {"minTokens": 50}, etc.). If the user specified a path, pass it as the path parameter.

2. The tool returns a JSON result with summary (clones, duplicatedLines, percentage, totalLines) and duplicates (already ranked by impact, highest first).

3. Present the top 10 results in a clear format:

   • Source file and lines
   • Duplicate file and lines
   • Number of duplicated lines and tokens
   • A brief suggestion for how to consolidate (extract to shared utility, parameterize, etc.)

4. Summarize overall duplication statistics: total clones found, total duplicated lines, duplication percentage.

5. If no duplication is found, confirm the codebase is clean.
