 ### Migration Guide
-- Update all statistics method calls to use `await`
-- Replace `EnhancedStatsTrackingMixin` with `BaseStatisticsTracker`
-- Use new async methods: `await component.get_stats()`, `await component.get_health_score()`
-- Backward compatibility: `get_memory_stats()` remains synchronous for compatibility
+
+#### From v3.2.x to v3.3.0
+
+**1. Update Statistics Method Calls**
+```python
+# Old (v3.2.x) - Mixed sync/async
+stats = suite.orders.get_order_statistics()  # Synchronous
+suite_stats = await suite.get_stats()        # Async
+
+# New (v3.3.0) - All async
+stats = await suite.orders.get_stats()       # Now async
+suite_stats = await suite.get_stats()        # Still async
+```
+
+**2. Replace Old Statistics Mixins**
+```python
+# Old (v3.2.x)
+from project_x_py.utils import EnhancedStatsTrackingMixin
+
+class MyComponent(EnhancedStatsTrackingMixin):
+    pass
+
+# New (v3.3.0)
+from project_x_py.statistics import BaseStatisticsTracker
+
+class MyComponent(BaseStatisticsTracker):
+    def __init__(self):
+        super().__init__()
+```
+
+**3. Use New Export Capabilities**
+```python
+# New in v3.3.0 - Multi-format export
+prometheus_metrics = await suite.export_stats("prometheus")
+csv_data = await suite.export_stats("csv")
+datadog_metrics = await suite.export_stats("datadog")
+```
+
+**4. Updated Health Monitoring**
+```python
+# Old (v3.2.x)
+stats = await suite.get_stats()
+health = stats['health_score']
+
+# New (v3.3.0) - Enhanced health API
+health_score = await suite.get_health_score()
+component_health = await suite.get_component_health()
+```
+
+**Breaking Changes:**
+- All component statistics methods now require `await`
+- `EnhancedStatsTrackingMixin` and `StatsTrackingMixin` removed
+- Component constructors now require `BaseStatisticsTracker` inheritance
+
+**Backward Compatibility:**
+- `get_memory_stats()` methods remain synchronous where needed
+- Main TradingSuite API remains unchanged
+- Event system and core trading operations unaffected

+
+### Agent Selection Best Practices
+
+1. **Use agents concurrently** when multiple tasks can be parallelized
+2. **Be specific** in task descriptions for agents
+3. **Choose the right agent** based on the task type, not just keywords
+4. **Use PROACTIVELY** - don't wait for user to request specific agents
+5. **Combine agents** for complex tasks (e.g., refactor → standards → review)
+
+### Example Multi-Agent Workflow
+
+```python
+# When implementing a new feature:
+1. python-developer: Implement the feature
+2. code-standards-enforcer: Verify compliance
+3. code-documenter: Add documentation  
+4. code-reviewer: Final review before commit
+```
+
+### Agent Command Requirements
+
+**Note**: Tool permissions are configured at the system level. This section documents common commands agents need.
+
+#### Commands Agents Typically Use
+
+**All Agents**:
+- `./test.sh [script]` - Run tests and examples with proper environment
+- File operations (Read, Write, Edit, MultiEdit)
+- `git status`, `git diff`, `git add` - Version control
+
+**python-developer**:
+- `uv run pytest` - Run test suite
+- `uv add [package]` - Add dependencies
+- `./test.sh examples/*.py` - Test example scripts
+
+**code-standards-enforcer**:
+- `mcp__ide__getDiagnostics` - **CHECK FIRST** - IDE diagnostics
+- `uv run ruff check .` - Lint code
+- `uv run ruff format .` - Format code  
+- `uv run mypy src/` - Type checking
+- `uv run pytest --cov` - Coverage reports
+
+**code-debugger**:
+- `./test.sh` with debug scripts
+- `grep` and search operations
+- Log analysis commands
+
+**code-reviewer**:
+- `git diff` - Review changes
+- `uv run pytest` - Verify tests pass
+- Static analysis tools
+
+#### Example Agent Command Workflow
+
+```bash
+# Agent workflow for implementing a feature
+1. python-developer:
+   - Edit src/project_x_py/new_feature.py
+   - ./test.sh tests/test_new_feature.py
+   
+2. code-standards-enforcer:
+   - mcp__ide__getDiagnostics  # ALWAYS CHECK FIRST
+   - uv run ruff check src/
+   - uv run mypy src/
+   - Fix any issues found
+   
+3. code-reviewer:
+   - mcp__ide__getDiagnostics  # Verify no issues remain
+   - git diff
+   - uv run pytest
+   - Review implementation
+```
+
+#### IDE Diagnostics Priority
+
+**CRITICAL**: The `code-standards-enforcer` agent must ALWAYS:
+1. **First** check `mcp__ide__getDiagnostics` for the modified files
+2. **Fix** any IDE diagnostic errors/warnings before proceeding
+3. **Then** run traditional linting tools (ruff, mypy)
+4. **Verify** with IDE diagnostics again after fixes
+
+This catches issues that mypy might miss, such as:
+- Incorrect method names (e.g., `get_statistics` vs `get_position_stats`)
+- Missing attributes on classes
+- Type mismatches that IDE's type checker detects
+- Real-time semantic errors
+
+### MCP Server Permissions for Agents
+
+**Note**: MCP server access is system-configured. Agents should have access to relevant MCP servers for their tasks.
+
+#### Essential MCP Servers for Agents

+
+3. Document in Obsidian:
+   await mcp__mcp_obsidian__obsidian_append_content(
+       filepath="Development/ProjectX SDK/Features/Order System.md",
+       content="## Bracket Order Implementation\n..."
+   )
+
+# code-debugger agent workflow  
+1. Analyze problem:
