+Automatically fix dependency issues found during validation.
+
+## Automatic Dependency Repair
+
+Intelligently fixes common dependency problems while preserving project logic.
+
+## Execution
+
+```bash
+task-master fix-dependencies
+```
+
+## What Gets Fixed
+
+### 1. **Auto-Fixable Issues**
+- Remove references to deleted tasks
+- Break simple circular dependencies
+- Remove self-dependencies
+- Clean up duplicate dependencies
+
+### 2. **Smart Resolutions**
+- Reorder dependencies to maintain logic
+- Suggest task merging for over-dependent tasks
+- Flatten unnecessary dependency chains
+- Remove redundant transitive dependencies
+
+### 3. **Manual Review Required**
+- Complex circular dependencies
+- Critical path modifications
+- Business logic dependencies
+- High-impact changes
+
+## Fix Process
+
+1. **Analysis Phase**
+   - Run validation check
+   - Categorize issues by type
+   - Determine fix strategy
+
+2. **Execution Phase**
+   - Apply automatic fixes
+   - Log all changes made
+   - Preserve task relationships
+
+3. **Verification Phase**
+   - Re-validate after fixes
+   - Show before/after comparison
+   - Highlight manual fixes needed
+
+## Smart Features
+
+- Preserves intended task flow
+- Minimal disruption approach
+- Creates fix history/log
+- Suggests manual interventions
+
+## Output Example
+
+```
+Dependency Auto-Fix Report
+━━━━━━━━━━━━━━━━━━━━━━━━
+Fixed Automatically:
+✅ Removed 2 references to deleted tasks
+✅ Resolved 1 self-dependency
+✅ Cleaned 3 redundant dependencies
+
+Manual Review Needed:
+⚠️ Complex circular dependency: #12 → #15 → #18 → #12
+  Suggestion: Make #15 not depend on #12
+⚠️ Task #45 has 8 dependencies
+  Suggestion: Break into subtasks
+
+Run '/project:tm/validate-dependencies' to verify fixes
+```
+
+## Safety
+
+- Preview mode available
+- Rollback capability
+- Change logging
+- No data loss
