+
+## Key Concepts
+
+### Token Efficiency Philosophy
+
+**We build what agents waste tokens on:**
+- ✅ Validators - Catch errors before execution
+- ✅ Parsers - Convert unstructured → structured
+- ✅ Extractors - Pull specific data
+- ✅ Formatters - Apply deterministic rules
+- ✅ Scanners - Rule-based detection
+
+**We avoid what agents do well:**
+- ❌ Code generators
+- ❌ Architecture tools
+- ❌ Refactoring tools
+
+### Design Patterns
+
+1. **Decorator Pattern** - Centralized `@strands_tool` decorator
+2. **Shared Utilities** - Common validation functions
+3. **JSON-Serializable Returns** - Google ADK compliance
+4. **Input Validation** - Clear error messages
+5. **Smart Confirmation** - Three-mode system (bypass/interactive/agent)
+
+### Framework Compatibility
+
+| Framework | Support | Notes |
+|-----------|---------|-------|
+| **Strands** | ✅ Full | All tools use `@strands_tool` decorator |
+| **Google ADK** | ✅ Full | JSON-serializable returns, no defaults |
+| **LangGraph** | ✅ Full | Works with standard callables |
+

+## Quick Reference
+
+### Token Savings by Use Case
+
+| Use Case | Without Tools | With Tools | Savings |
+|----------|--------------|------------|---------|
+| Python validation | 1700 tokens | 950 tokens | 44% |
+| Git health check | 1000 tokens | 200 tokens | 80% |
+| Code navigation | 1700 tokens | 180 tokens | 89% |
+| Security scanning | 8500 tokens | 600 tokens | 93% |
+| Config parsing | 1000 tokens | 80 tokens | 92% |
+
+**Average: 80-90% token savings**
+
+### Common Workflows
+
+#### 1. Validate Generated Code
+```python
+from coding_open_agent_tools.python import validators
+
+result = validators.validate_python_syntax(generated_code)
+if result['is_valid'] == 'true':
+    # Code is valid, proceed
+    pass
+```
+
+#### 2. Navigate Codebase
+```python
+from coding_open_agent_tools.python import navigation
+
+# Get overview
+overview = navigation.get_python_module_overview(source_code)
+
+# Get line numbers for specific function
+lines = navigation.get_python_function_line_numbers(source_code, "my_function")
+# Use with Read tool for targeted reading
+```
+
+#### 3. Check Repository Health
+```python
+from coding_open_agent_tools.git import health
+
+metrics = health.get_repository_metrics(repo_path)
+print(f"Health score: {metrics['health_score']}/100")
+```
+
+#### 4. Scan for Secrets
+```python
+from coding_open_agent_tools.analysis import secrets
+
+result = secrets.scan_for_secrets(code_content)
+if result['secret_count'] != '0':
+    # Handle found secrets
+    pass
+```
+
+#### 5. Parse Configuration
+```python
+from coding_open_agent_tools.config import extractors
+
+db_host = extractors.extract_yaml_value(config_content, "database.host")
+print(f"Database host: {db_host['value']}")
+```
