+### Complex Pattern Discovery
+For targeted analysis, use semantic discovery BEFORE CLI execution:
+
+```bash
+# Step 1: Discover relevant files
+rg "specific_pattern" --files-with-matches --type ts
+mcp__code-index__search_code_advanced(pattern="target_code", file_pattern="*.ts")
+
+# Step 2: Build CONTEXT with discovered files
+CONTEXT: @{CLAUDE.md} @{src/file1.ts,src/file2.ts}
+
+# Step 3: Execute chat command
+cd src && ~/.claude/scripts/gemini-wrapper -p "
+PURPOSE: Answer specific inquiry
+CONTEXT: @{CLAUDE.md,file1.ts,file2.ts}
+EXPECTED: Detailed response
