+Display the task complexity analysis report.
+
+Arguments: $ARGUMENTS
+
+View the detailed complexity analysis generated by analyze-complexity command.
+
+## Viewing Complexity Report
+
+Shows comprehensive task complexity analysis with actionable insights.
+
+## Execution
+
+```bash
+task-master complexity-report [--file=<path>]
+```
+
+## Report Location
+
+Default: `.taskmaster/reports/complexity-analysis.md`
+Custom: Specify with --file parameter
+
+## Report Contents
+
+### 1. **Executive Summary**
+```
+Complexity Analysis Summary
+━━━━━━━━━━━━━━━━━━━━━━━━
+Analysis Date: 2024-01-15
+Tasks Analyzed: 32
+High Complexity: 5 (16%)
+Medium Complexity: 12 (37%)
+Low Complexity: 15 (47%)
+
+Critical Findings:
+- 5 tasks need immediate expansion
+- 3 tasks have high technical risk
+- 2 tasks block critical path
+```
+
+### 2. **Detailed Task Analysis**
+For each complex task:
+- Complexity score breakdown
+- Contributing factors
+- Specific risks identified
+- Expansion recommendations
+- Similar completed tasks
+
+### 3. **Risk Matrix**
+Visual representation:
+```
+Risk vs Complexity Matrix
+━━━━━━━━━━━━━━━━━━━━━━━
+High Risk  | #5(9) #12(8) | #23(6)
+Med Risk   | #34(7)       | #45(5) #67(5)
+Low Risk   | #78(8)       | [15 tasks]
+           | High Complex  | Med Complex
+```
+
+### 4. **Recommendations**
+
+**Immediate Actions:**
+1. Expand task #5 - Critical path + high complexity
+2. Expand task #12 - High risk + dependencies
+3. Review task #34 - Consider splitting
+
+**Sprint Planning:**
+- Don't schedule multiple high-complexity tasks together
+- Ensure expertise available for complex tasks
+- Build in buffer time for unknowns
+
