+### Response Style Options
+
+Control the verbosity and communication style of JURIKO responses:
+
+```bash
+# Concise mode - short, direct responses (< 4 lines)
+juriko --concise
+
+# Verbose mode - detailed explanations and context
+juriko --verbose
+
+# Security level control
+juriko --security-level high    # Strict validation
+juriko --security-level medium  # Standard validation (default)
+juriko --security-level low     # Basic validation
+```
+
+**Response Style Benefits:**
+- **Concise Mode**: Up to 65% reduction in response length, faster interactions
+- **Verbose Mode**: Full explanations for learning and complex tasks
+- **Balanced Mode** (default): Optimal mix of efficiency and helpfulness
+
+### Multi-Tool Batching
+
+Enable parallel execution of independent tools for improved performance:
+
+```bash
+# Enable batching (parallel execution)
+juriko --enable-batching
+
+# Disable batching (sequential execution)
+juriko --disable-batching
+```
+
+Or via environment variable:
+```bash
+export JURIKO_ENABLE_BATCHING=true  # or 'false'
+```
+
+**Performance Benefits:**
+- **Up to 40% faster execution** when multiple independent tools are used
+- **Intelligent dependency detection** ensures file operations remain safe
+- **Automatic fallback** to sequential execution if parallel execution fails
+- **Smart categorization** of tools (read-only, write, compute, network, bash)
+
+**How it works:**
+- Read-only tools (like `view_file`) can run in parallel with each other
+- Write tools (like `create_file`, `str_replace_editor`) run sequentially for safety
+- Bash commands run sequentially to prevent conflicts
+- Network and compute tools are intelligently batched based on dependencies
+
+### Code Reference System
+
+Enhanced file navigation with clickable references inspired by Claude Code patterns:
+
+```bash
+# Enable code references (enabled by default)
+juriko --enable-code-references
+
+# Disable code references
+juriko --disable-code-references
+```
+
+Or via environment variable:
+```bash
+export JURIKO_ENABLE_CODE_REFERENCES=true  # or 'false'
+```
+
+**Features:**
+- **Clickable file references**: All file mentions become clickable links
+- **Line-specific navigation**: Jump directly to specific lines in files
+- **VSCode integration**: Links open directly in VSCode editor
+- **Automatic enhancement**: Tool outputs automatically include clickable references
+- **Context awareness**: Shows code context around referenced lines
+
+**Examples:**
+- File reference: [`package.json`](vscode://file/package.json)
+- Line reference: [`src/index.ts:42`](vscode://file/src/index.ts:42)
+- Error reference: [`src/utils/helper.ts:15`](vscode://file/src/utils/helper.ts:15)
