+
+## Common Issues & Fixes
+
+### Code Smells
+
+#### Long Functions
+**Issue:**
+```python
+def process_user_request(request):
+    # 200 lines of code
+    ...
+```
+
+**Fix:**
+```python
+def process_user_request(request):
+    user = authenticate_user(request)
+    data = validate_request_data(request)
+    result = execute_business_logic(user, data)
+    return format_response(result)
+```
+
+#### Magic Numbers
+**Issue:**
+```python
+if user.failed_attempts > 5:
+    lock_account(user, 900)
+```
+
+**Fix:**
+```python
+MAX_FAILED_ATTEMPTS = 5
+LOCKOUT_DURATION_SECONDS = 15 * 60
+
+if user.failed_attempts > MAX_FAILED_ATTEMPTS:
+    lock_account(user, LOCKOUT_DURATION_SECONDS)
+```
+
+#### Missing Error Handling
+**Issue:**
+```python
+def get_user(user_id):
+    return db.query(User).get(user_id).email
+```
+
+**Fix:**
+```python
+def get_user_email(user_id):
+    user = db.query(User).get(user_id)
+    if not user:
+        raise UserNotFoundError(f"User {user_id} not found")
+    return user.email
+```
+
+### Testing Issues
+
+#### Flaky Tests
+**Issue:** Tests pass/fail randomly
+
+**Causes:**
+- Time dependencies
+- External service calls
+- Shared state
+- Race conditions
+
+**Fix:**
+- Use fixed time in tests
+- Mock external services
+- Isolate test state
+- Proper async handling
+
+#### Incomplete Coverage
+**Issue:** Missing edge cases
+
+**Fix:**
+```python
+# Test happy path
+def test_divide_normal():
+    assert divide(10, 2) == 5
+
+# Test edge cases ✓
+def test_divide_by_zero():
+    with pytest.raises(ZeroDivisionError):
+        divide(10, 0)
+
+def test_divide_negative():
+    assert divide(-10, 2) == -5
+
+def test_divide_floats():
+    assert divide(10.5, 2.5) == 4.2
+```
+
+### Security Issues
+
+#### SQL Injection
+**Issue:**
+```python
+query = f"SELECT * FROM users WHERE id = {user_id}"
+```
+
+**Fix:**
+```python
+query = "SELECT * FROM users WHERE id = ?"
+db.execute(query, (user_id,))
+```
+
+#### Hardcoded Secrets
+**Issue:**
+```python
+API_KEY = "sk_live_abc123xyz"
+```
+
+**Fix:**
+```python
+import os
+API_KEY = os.getenv("API_KEY")
+if not API_KEY:
+    raise ConfigError("API_KEY not configured")
+```
+
+#### Missing Authentication
+**Issue:**
+```python
+@app.route('/api/users/<id>')
+def get_user(id):
+    return User.get(id)
+```
+
+**Fix:**
+```python
+@app.route('/api/users/<id>')
+@require_authentication
+@require_authorization('read:users')
+def get_user(id):
+    return User.get(id)
+```

+
+### Tracking Relationships
+Maintain task dependencies in descriptions and execution order
+
+## Best Practices
+
+### Always
+- Start with "why" - understand business value
+- Define clear success criteria upfront
+- Break large tasks into <1 day chunks
+- Identify dependencies explicitly
+- Plan for testing and documentation
+- Include time estimates with ranges
+
+### Never
+- Skip requirements clarification
+- Assume unstated requirements
+- Create tasks >2 days without breakdown
+- Ignore risk factors
+- Plan without considering resources
+
+### When in Doubt
+- Ask clarifying questions
+- Consult with Tech Lead
+- Create spike task for investigation
+- Start with MVP approach
+- Build in validation checkpoints
+
+Remember: As the Task Planner, your role is to ensure every complex task has a clear, achievable path to successful completion. Proper planning prevents poor performance!
