-USAGE:
-    mcp-semantic [FLAGS]
-
-FLAGS:
-    --project-root <PATH>    Root directory of the project to analyze (default: ".")
-    --config <FILE>          Path to configuration file  
-    --log-level <LEVEL>      Log level: debug, info, warn, error (default: "info")

-
-DESCRIPTION:
-    The Semantic MCP Server provides AI assistants with intelligent, symbol-aware 
-    code operations. It leverages Language Server Protocol (LSP) to understand code 
-    structure and relationships across multiple programming languages.
-
-SUPPORTED LANGUAGES:
-    • Go          (via gopls)
-    • Rust        (via rust-analyzer)  
-    • Ruby        (via solargraph)
-    • Python      (via python-lsp-server)
-    • JavaScript  (via typescript-language-server)
-    • TypeScript  (via typescript-language-server)
-    • HTML        (via vscode-html-language-server)
-    • CSS         (via vscode-css-language-server)
-
-AVAILABLE TOOLS:
-    Symbol Discovery (Phase 1 - ✅ Complete):
-      • semantic_find_symbol        - Find symbols by name, type, or pattern
-      • semantic_get_overview       - Get high-level code structure overview
-      • semantic_get_definition     - Get detailed symbol information
-
-    Code Analysis (Phase 2 - ✅ Complete):
-      • semantic_get_references     - Find all symbol usages with context
-      • semantic_get_call_hierarchy - Understand calling relationships (incoming/outgoing)
-      • semantic_analyze_dependencies - Map symbol dependencies and relationships
-
-    Semantic Editing (Phase 3 - 🚧 Planned):
-      • semantic_replace_symbol     - Replace symbol implementations safely
-      • semantic_insert_after_symbol - Insert code after specific symbols
-      • semantic_rename_symbol      - Rename symbols across entire project
-
-LANGUAGE SERVER REQUIREMENTS:
-    Install the required language servers for your languages:
-
-    # Go
-    go install golang.org/x/tools/gopls@latest
-
-    # Rust  
-    rustup component add rust-analyzer
-
-    # Ruby
-    gem install solargraph
-
-    # Python
-    pip install python-lsp-server
-
-    # JavaScript/TypeScript
-    npm install -g typescript-language-server typescript
-

-    npm install -g vscode-langservers-extracted
-
-EXAMPLES:
-    # Basic usage with current directory
-    mcp-semantic
-
-    # Analyze specific project
-    mcp-semantic --project-root /path/to/project
-
-    # With custom configuration
-    mcp-semantic --config semantic-config.json --log-level debug
-
-    # Find symbols in Go project
-    echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": {"name": "semantic_find_symbol", "arguments": {"name": "main", "kind": "function", "language": "go"}}}' | mcp-semantic
-
-    # Get references to a function
-    echo '{"jsonrpc": "2.0", "id": 2, "method": "tools/call", "params": {"name": "semantic_get_references", "arguments": {"symbol": "UserService.authenticate", "context_lines": 3}}}' | mcp-semantic
-
-    # Analyze call hierarchy
-    echo '{"jsonrpc": "2.0", "id": 3, "method": "tools/call", "params": {"name": "semantic_get_call_hierarchy", "arguments": {"symbol": "main", "direction": "both", "max_depth": 3}}}' | mcp-semantic
-
-CONFIGURATION:
-    Create a semantic-config.json file for custom settings:
-    
-    {
-      "project": {
-        "exclude_patterns": ["**/vendor/**", "**/node_modules/**"]
-      },
-      "language_servers": {
-        "go": {"enabled": true, "timeout": 30},
-        "rust": {"enabled": true, "timeout": 60}
-      }
-    }
