+### 7. merge-pull-request.sh
+
+Merge a pull request with automatic source branch cleanup. Uses squash merge strategy by default for clean commit history.
+
+**Usage:**
+```bash
+./merge-pull-request.sh [options]
+```
+
+**Options:**
+- `-h, --help`: Show help message
+- `-p, --pr <NUMBER>`: Pull request number (required)
+- `-s, --strategy <TYPE>`: Merge strategy: `squash`, `merge`, `rebase` (default: `squash`)
+- `-d, --delete-branch`: Delete source branch after merge (default behavior)
+- `--keep-branch`: Keep source branch after merge (don't delete)
+- `-f, --force`: Skip confirmation prompt
+- `--dry-run`: Show what would be done without applying
+- `-m, --message <MSG>`: Custom commit message (for squash merge)
+
+**Examples:**
+```bash
+# Merge PR #35 using squash strategy and delete branch
+./merge-pull-request.sh --pr 35
+
+# Merge with rebase strategy
+./merge-pull-request.sh -p 35 --strategy rebase
+
+# Merge without deleting source branch
+./merge-pull-request.sh --pr 33 --keep-branch
+
+# Force merge without confirmation
+./merge-pull-request.sh -p 34 --force
+
+# Preview merge without applying
+./merge-pull-request.sh --pr 36 --dry-run
+
+# Merge using standard merge strategy
+./merge-pull-request.sh --pr 37 --strategy merge --force
+```
+
+**Merge Strategies:**
+- **squash** (default) - Squash all commits into single commit for clean history
+- **merge** - Create merge commit preserving all commit history
+- **rebase** - Rebase commits on top of target branch
+
+**How It Works:**
+
+1. Fetches PR details from GitHub
+2. Validates PR state and status checks
+3. Merges PR using specified strategy
+4. Automatically deletes source branch (unless `--keep-branch` is used)
+5. Displays merge summary and next steps
+
+**Features:**
+- ✅ Multiple merge strategies supported
+- ✅ Automatic branch cleanup after merge
+- ✅ Status check verification
+- ✅ Dry-run mode for safe preview
+- ✅ Force mode for automation
+- ✅ Confirmation prompt (optional)
+- ✅ Clear error handling
+
+**Sample Output:**
+```
