+description: Clean up duplicate GitHub issues for a Feature. Finds issues with duplicate titles and closes all except the first created issue.
+justification: |
+  CRITICAL INCIDENT RESPONSE TOOL - DO NOT DELETE!
+
+  Why This Command Exists:
+  - Prevention systems (deduplication, GitHub self-healing) work for single-process execution
+  - Multiple parallel Claude Code instances bypass all prevention (file-based cache, no distributed locking)
+  - GitHub API race conditions: Time gap between "check exists" and "create issue" allows duplicates
+  - Historical duplicates from pre-v0.14.1 users (before prevention was added)
+
+  Evidence of Need:
+  - 2025-11-13: 123 duplicate GitHub issues incident (cleaned to 29 unique)
+  - Parallel execution creates race conditions that prevention CANNOT solve
+  - Industry standard: Prevention + Detection + Cleanup (defense in depth)
+
+  When to Delete:
+  - ONLY if distributed locking implemented (Redis/file locks)
+  - AND parallel execution tested (100+ concurrent syncs with zero duplicates)
+  - AND zero duplicates for 6+ months in production
+  - AND all users migrated to prevention-enabled versions
+

+# Clean Up Duplicate GitHub Issues
+
+**CRITICAL**: This command detects and closes duplicate GitHub issues created by multiple syncs.
+
+## Usage
+
+```bash
+/specweave-github:cleanup-duplicates <epic-id> [--dry-run]
+```
+
+## What It Does
+
+**Duplicate Detection & Cleanup**:
+
+1. **Find all issues** for the Epic (searches by Epic ID in title)
+2. **Group by title** (detect duplicates)
+3. **For each duplicate group**:
+   - Keep the **FIRST created** issue (lowest number)
+   - Close all **LATER** issues with comment: "Duplicate of #XXX"
+4. **Update Epic README** with correct issue numbers
+
+## Examples
+
+### Dry Run (No Changes)
+
+```bash
+/specweave-github:cleanup-duplicates FS-031 --dry-run
+```
+
+**Output**:
+```
+🔍 Scanning for duplicates in Epic FS-031...
+   Found 25 total issues
+   Detected 10 duplicate groups:
+
+   📋 Group 1: "[FS-031] External Tool Status Synchronization"
+      - #250 (KEEP) - Created 2025-11-10
+      - #255 (CLOSE) - Created 2025-11-11 - DUPLICATE
+      - #260 (CLOSE) - Created 2025-11-12 - DUPLICATE
+
+   📋 Group 2: "[FS-031] Multi-Project GitHub Sync"
+      - #251 (KEEP) - Created 2025-11-10
+      - #256 (CLOSE) - Created 2025-11-11 - DUPLICATE
+
+   ...
+
+✅ Dry run complete!
+   Total issues: 25
+   Duplicate groups: 10
+   Issues to close: 15
+
+⚠️  This was a DRY RUN - no changes made.
+   Run without --dry-run to actually close duplicates.
+```
+
+### Actual Cleanup
+
+```bash
+/specweave-github:cleanup-duplicates FS-031
+```
+
+**Output**:
+```
+🔍 Scanning for duplicates in Epic FS-031...
+   Found 25 total issues
+   Detected 10 duplicate groups
+
+⚠️  CONFIRM: Close 15 duplicate issues? [y/N]
+> y
+
+🗑️  Closing duplicates...
+   ✅ Closed #255 (duplicate of #250)
+   ✅ Closed #256 (duplicate of #251)
+   ✅ Closed #260 (duplicate of #250)
+   ...
+
+📝 Updating Epic README frontmatter...
+   ✅ Updated frontmatter with correct issue numbers
+
+✅ Cleanup complete!
+   Closed: 15 duplicates
+   Kept: 10 original issues
+```
+
+## Arguments
+
+- `<epic-id>` - Epic ID (e.g., `FS-031` or just `031`)
+- `--dry-run` - Preview changes without actually closing issues (optional)
+
+## Safety Features
+
+✅ **Confirmation prompt**: Asks before closing issues (unless --dry-run)
+✅ **Dry run mode**: Preview changes safely
+✅ **Keeps oldest issue**: Preserves the first created issue
+✅ **Adds closure comment**: Links to the original issue
+✅ **Updates metadata**: Fixes Epic README frontmatter
+
+## What Gets Closed
+
+**Closed issues**:
+- ✅ Duplicate titles (second, third, etc. occurrences)
+- ✅ Closed with comment: "Duplicate of #XXX"
+- ✅ Original issue kept open (or maintains its status)
+
+**Example comment on closed duplicate**:
+```markdown
+Duplicate of #250
+
+This issue was automatically closed by SpecWeave cleanup because it is a duplicate.
+
+The original issue (#250) contains the same content and should be used for tracking instead.
+
+🤖 Auto-closed by SpecWeave Duplicate Cleanup
+```
+
+## Requirements
+
+1. **GitHub CLI** (`gh`) installed and authenticated
+2. **Write access** to repository (for closing issues)
+3. **Epic folder exists** at `.specweave/docs/internal/specs/FS-XXX-name/`
+
+## When to Use
+
+**Use this command when**:
+- ✅ You see multiple issues with the same title in GitHub
+- ✅ Epic sync ran multiple times and created duplicates
+- ✅ Epic README frontmatter got corrupted and reset
+- ✅ Post-sync validation warns about duplicates
+
+**Example warning that triggers this**:
+```
+⚠️  WARNING: 10 duplicate(s) detected!
+   Run cleanup command to resolve:
+   /specweave-github:cleanup-duplicates FS-031
+```
+
+## Troubleshooting
+
+**"No duplicates found"**:
+- Good! Your Epic has no duplicate issues
+- Run epic sync is working correctly with duplicate detection
+
+**"GitHub CLI not authenticated"**:
+- Run: `gh auth login`
+- Ensure you have write access to the repository
+
+**"Could not find Epic folder"**:
+- Check Epic exists: `ls .specweave/docs/internal/specs/`
+- Verify Epic ID format: `FS-031-epic-name/`
+
+**"Error closing issue"**:
+- Check GitHub CLI: `gh auth status`
+- Verify write permissions: `gh repo view`
+
+## Architecture
+
+**Duplicate Detection Logic**:
+1. Group issues by **exact title match**
+2. Within each group, sort by **issue number** (ascending)
+3. Keep **first issue** (lowest number = oldest)
+4. Close **all others** as duplicates
+
+**Why lowest number?**:
+- Lower issue numbers were created first
+- Preserves chronological order
+- Maintains links from old documentation
+
+## Related Commands
+
+- `/specweave-github:sync` - Sync Feature to GitHub (with duplicate detection)
+- `/specweave:validate` - Validate increment completeness
+- `gh issue list` - View all issues (GitHub CLI)
+
+## Implementation
+
+**File**: `plugins/specweave-github/lib/duplicate-detector.ts`
+
+**Class**: `DuplicateDetector`
+
+**Algorithm** (3-phase protection):
+1. **Detection**: Search GitHub for existing issues matching pattern
+2. **Verification**: Count check to detect duplicates after creation
+3. **Reflection**: Auto-close duplicates automatically
+
+For manual cleanup:
+1. Search GitHub for all issues with Feature ID
+2. Group by title (Map<string, number[]>)
+3. Filter groups with >1 issue (duplicates)
+4. For each duplicate group:
+   - Keep first issue (lowest number)
+   - Close others with gh CLI
+
+## Next Steps
+
+After cleanup:
+
+1. **Verify cleanup**: `gh issue list --search "[FS-031]"`
+2. **Check Feature FEATURE.md**: Verify frontmatter has correct issue numbers
+3. **Re-run sync**: `/specweave-github:sync` (should show no duplicates)
+4. **Duplicate detection**: Automatically enabled via DuplicateDetector

+
+**✅ SAFE TO USE**: This command is idempotent and safe to run multiple times.
