<h2>Real Usage Patterns</h2>
<div class="comparison-table">
<p><strong>Read Tool Usage:</strong></p>
<ul>
<li>{claude_analysis['summary']['read_with_limit_percentage']:.1f}% of reads use limit parameter (efficient)</li>
<li>{claude_analysis['summary']['read_full_file_percentage']:.1f}% read entire files (token-intensive)</li>
</ul>
<p><strong>Edit Patterns:</strong></p>
<ul>
<li>Partial edits: {claude_analysis['summary']['edit_patterns'].get('partial', 0)} occurrences</li>
<li>Full file rewrites: {claude_analysis['summary']['edit_patterns'].get('full_rewrite', 0)} occurrences</li>
</ul>
</div>
</div>
<div class="section">
<h2>Recommendations</h2>
<div class="recommendation">
<h3>✅ Use MCP Tools For:</h3>
<ul>
<li><strong>Symbol lookups</strong> - 70x faster than grep for finding class/function definitions</li>
<li><strong>Cross-file searches</strong> - Eliminates need for multiple grep + read operations</li>
<li><strong>Large codebases</strong> - Pre-indexed search scales better than filesystem traversal</li>
<li><strong>Repeated searches</strong> - Cached index provides consistent fast performance</li>
</ul>
</div>
<div class="warning">
<h3>⚠️ Use Direct Tools For:</h3>
<ul>
<li><strong>Unindexed files</strong> - New files or repos without indexes</li>
<li><strong>Full context needed</strong> - When you need to see entire file contents</li>
<li><strong>Simple file navigation</strong> - Basic ls/find operations</li>
<li><strong>One-off searches</strong> - Quick checks in small codebases</li>
</ul>
</div>
</div>
<div class="section">
<h2>Potential Token Savings</h2>
<p>If MCP usage increased from {mcp_usage:.1f}% to 30% for appropriate queries:</p>
<div class="metric-card" style="max-width: 400px; margin: 20px auto;">
<div class="metric-label">Estimated Token Savings</div>
<div class="metric-value" style="color: #27ae60;">{int((30-mcp_usage)*token_reduction/100)}%</div>
<div class="metric-label">reduction in total token usage</div>
</div>
</div>
<div class="section">
<h2>Implementation Status</h2>
<p><strong>Indexed Repositories:</strong> 14+ repositories centrally indexed</p>
<p><strong>Index Location:</strong> ~/.mcp/indexes/</p>
<p><strong>Available MCP Tools:</strong></p>
<ul>
<li>mcp__code-index-mcp__symbol_lookup - Fast symbol definition lookup</li>
<li>mcp__code-index-mcp__search_code - Semantic and keyword code search</li>
<li>mcp__code-index-mcp__get_status - Check index health</li>
<li>mcp__code-index-mcp__reindex - Update indexes</li>
