+Remove a dependency between tasks.
+
+Arguments: $ARGUMENTS
+
+Parse the task IDs to remove dependency relationship.
+
+## Removing Dependencies
+
+Removes a dependency relationship, potentially unblocking tasks.
+
+## Argument Parsing
+
+Parse natural language or IDs:
+- "remove dependency between 5 and 3"
+- "5 no longer needs 3"
+- "unblock 5 from 3"
+- "5 3" → remove dependency of 5 on 3
+
+## Execution
+
+```bash
+task-master remove-dependency --id=<task-id> --depends-on=<dependency-id>
+```
+
+## Pre-Removal Checks
+
+1. **Verify dependency exists**
+2. **Check impact on task flow**
+3. **Warn if it breaks logical sequence**
+4. **Show what will be unblocked**
+
+## Smart Analysis
+
+Before removing:
+- Show why dependency might have existed
+- Check if removal makes tasks executable
+- Verify no critical path disruption
+- Suggest alternative dependencies
+
+## Post-Removal
+
+After removing:
+1. Show updated task status
+2. List newly unblocked tasks
+3. Update project timeline
+4. Suggest next actions
+
+## Safety Features
+
+- Confirm if removing critical dependency
+- Show tasks that become immediately actionable
+- Warn about potential issues
+- Keep removal history
+
+## Example
+
+```
+/taskmaster:remove-dependency 5 from 3
+→ Removed: Task #5 no longer depends on #3
+→ Task #5 is now UNBLOCKED and ready to start
+→ Warning: Consider if #5 still needs #2 completed first
+```
