+# Add Missing i18n Translations
+
+## Task: Add English translations for all new localized strings
+
+### Step 1: Identify new translation keys
+Find all translation keys that were added in the current branch's changes. These keys appear as arguments to translation functions: `t()`, `st()`, `$t()`, or similar i18n functions.
+
+### Step 2: Add translations to English locale file
+For each new translation key found, add the corresponding English text to the file `src/locales/en/main.json`.
+
+### Key-to-JSON mapping rules:
+- Translation keys use dot notation to represent nested JSON structure
+- Convert dot notation to nested JSON objects when adding to the locale file
+- Example: The key `g.user.name` maps to:
+  ```json
+  {
+    "g": {
+      "user": {
+        "name": "User Name"
+      }
+    }
+  }
+  ```
+
+### Important notes:
+1. **Only modify the English locale file** (`src/locales/en/main.json`)
+2. **Do not modify other locale files** - translations for other languages are automatically generated by the `i18n.yaml` workflow
+3. **Exception for manual translations**: Only add translations to non-English locale files if:
+   - You have specific domain knowledge that would produce a more accurate translation than the automated system
+   - The automated translation would likely be incorrect due to technical terminology or context-specific meaning
+
+### Example workflow:
+1. If you added `t('settings.advanced.enable')` in a Vue component
+2. Add to `src/locales/en/main.json`:
+   ```json
+   {
+     "settings": {
+       "advanced": {
+         "enable": "Enable advanced settings"
+       }
+     }
+   }
+   ```

+# Comprehensive PR Review for ComfyUI Frontend
+
+<task>
+You are performing a comprehensive code review for PR #$1 in the ComfyUI frontend repository. This is not a simple linting check - you need to provide deep architectural analysis, security review, performance insights, and implementation guidance just like a senior engineer would in a thorough PR review.
+
+Your review should cover:
+1. Architecture and design patterns
+2. Security vulnerabilities and risks
+3. Performance implications
+4. Code quality and maintainability
+5. Integration with existing systems
+6. Best practices and conventions
+7. Testing considerations
+8. Documentation needs

+```
+
+## Phase 3: Deep Analysis Instructions
+
+Perform a comprehensive analysis covering these areas:
+
+### 3.1 Architectural Analysis
+Based on the repository guide and project summary, evaluate:
+- Does this change align with the established architecture patterns?
+- Are domain boundaries respected?
+- Is the extension system used appropriately?
+- Are components properly organized by feature?
+- Does it follow the established service/composable/store patterns?
+
+### 3.2 Code Quality Beyond Linting
+- Cyclomatic complexity and cognitive load
+- SOLID principles adherence
+- DRY violations that aren't caught by simple duplication checks
+- Proper abstraction levels
+- Interface design and API clarity
+- No leftover debug code (console.log, commented code, TODO comments)
+
+### 3.3 Library Usage Enforcement
+CRITICAL: Never re-implement functionality that exists in our standard libraries:
+- **Tailwind CSS**: Use utility classes instead of custom CSS or style attributes
+- **PrimeVue**: Never re-implement components that exist in PrimeVue (buttons, modals, dropdowns, etc.)
+- **VueUse**: Never re-implement composables that exist in VueUse (useLocalStorage, useDebounceFn, etc.)
+- **Lodash**: Never re-implement utility functions (debounce, throttle, cloneDeep, etc.)
+- **Common components**: Reuse components from src/components/common/
+- **DOMPurify**: Always use for HTML sanitization
+- **Fuse.js**: Use for fuzzy search functionality
+- **Marked**: Use for markdown parsing
+- **Pinia**: Use for global state management, not custom solutions
+- **Zod**: Use for form validation with zodResolver pattern
+- **Tiptap**: Use for rich text/markdown editing
+- **Xterm.js**: Use for terminal emulation
+- **Axios**: Use for HTTP client initialization
+
+### 3.4 Security Deep Dive
+Beyond obvious vulnerabilities:
+- Authentication/authorization implications
+- Data validation completeness
+- State management security
+- Cross-origin concerns
+- Extension security boundaries
+
+### 3.5 Performance Analysis
+- Render performance implications
+- Layout thrashing prevention
+- Memory leak potential
+- Network request optimization
+- State management efficiency
+
+### 3.6 Integration Concerns
+- Breaking changes to internal APIs
+- Extension compatibility
+- Backward compatibility
+- Migration requirements
+
+## Phase 4: Create Detailed Review Comments
+
+CRITICAL: Keep comments extremely concise and effective. Use only as many words as absolutely necessary.
+- NO markdown formatting (no #, ##, ###, **, etc.)
+- NO emojis
+- Get to the point immediately
+- Burden the reader as little as possible
+
+For each issue found, create a concise inline comment with:
+1. What's wrong (one line)
+2. Why it matters (one line)
+3. How to fix it (one line)
+4. Code example only if essential
+
+```bash
+# Helper function for comprehensive comments
+post_review_comment() {
+  local file_path=$1
+  local line_number=$2
+  local severity=$3  # critical/high/medium/low
+  local category=$4  # architecture/security/performance/quality
+  local issue=$5
+  local context=$6
+  local suggestion=$7
+  local example=$8
+  
+  local body="### [$category] $severity Priority
+
+**Issue**: $issue
+
+**Context**: $context
+
+**Suggestion**: $suggestion"
+
+  if [ -n "$example" ]; then
+    body="$body
+
+**Example**:
+\`\`\`typescript
+$example
+\`\`\`"
+  fi
+
+  body="$body
+
+*Related: See [repository guide](https://github.com/Comfy-Org/comfy-claude-prompt-library/blob/master/project-summaries-for-agents/ComfyUI_frontend/REPOSITORY_GUIDE.md) for patterns*"
+
+  gh api -X POST /repos/$REPOSITORY/pulls/$PR_NUMBER/comments \
+    -f path="$file_path" \
+    -f line=$line_number \
+    -f body="$body" \
+    -f commit_id="$COMMIT_SHA" \
+    -f side='RIGHT' || echo "Failed to post comment at $file_path:$line_number"
+}
+```
+
+## Phase 5: Validation Rules Application
+
+Apply ALL validation rules from the loaded knowledge, but focus on the changed lines:
+
+### From Frontend Standards
+- Vue 3 Composition API patterns
+- Component communication patterns
+- Proper use of composables
+- TypeScript strict mode compliance
+- Bundle optimization
+
+### From Security Audit
+- Input validation
+- XSS prevention
+- CSRF protection
+- Secure state management
+- API security
+
+### From Performance Check
+- Render optimization
+- Memory management
+- Network efficiency
+- Bundle size impact
+
+## Phase 6: Contextual Review Based on PR Type
+
+Analyze the PR description and changes to determine the type:
+
+```bash
+# Extract PR metadata with error handling
+if [ ! -f pr_info.json ]; then
+  echo "Error: pr_info.json not found"
+  exit 1
+fi
+
+PR_TITLE=$(jq -r '.title // "Unknown"' < pr_info.json)
+PR_BODY=$(jq -r '.body // ""' < pr_info.json)
+FILE_COUNT=$(wc -l < changed_files.txt)
+ADDITIONS=$(jq -r '.additions // 0' < pr_info.json)
+DELETIONS=$(jq -r '.deletions // 0' < pr_info.json)
+
+# Determine PR type and apply specific review criteria
+if echo "$PR_TITLE $PR_BODY" | grep -qiE "(feature|feat)"; then
+  echo "Detected feature PR - applying feature review criteria"
+  # Check for tests, documentation, backward compatibility
+elif echo "$PR_TITLE $PR_BODY" | grep -qiE "(fix|bug)"; then
+  echo "Detected bug fix - checking root cause and regression tests"
+  # Verify fix addresses root cause, includes tests
+elif echo "$PR_TITLE $PR_BODY" | grep -qiE "(refactor)"; then
+  echo "Detected refactoring - ensuring behavior preservation"
+  # Check that tests still pass, no behavior changes
+fi
+```
+
+## Phase 7: Generate Comprehensive Summary
+
+After all inline comments, create a detailed summary:
+
+```bash
+# Initialize metrics tracking
+REVIEW_START_TIME=$(date +%s)
+
+# Create the comprehensive summary
+gh pr review $PR_NUMBER --comment --body "# Comprehensive PR Review
+
+This review is generated by Claude. It may not always be accurate, as with human reviewers. If you believe that any of the comments are invalid or incorrect, please state why for each. For others, please implement the changes in one way or another.
+
+## Review Summary
+
+**PR**: $PR_TITLE (#$PR_NUMBER)
+**Impact**: $ADDITIONS additions, $DELETIONS deletions across $FILE_COUNT files
+
+### Issue Distribution
+- Critical: $CRITICAL_COUNT
+- High: $HIGH_COUNT
+- Medium: $MEDIUM_COUNT
+- Low: $LOW_COUNT
+
+### Category Breakdown
+- Architecture: $ARCHITECTURE_ISSUES issues
+- Security: $SECURITY_ISSUES issues
+- Performance: $PERFORMANCE_ISSUES issues
+- Code Quality: $QUALITY_ISSUES issues

+## Next Steps
+1. Address critical issues before merge
+2. Consider architectural feedback for long-term maintainability
+3. Add tests for uncovered scenarios
+4. Update documentation if needed
+
+---
+*This is a comprehensive automated review. For architectural decisions requiring human judgment, please request additional manual review.*"
+```
+
+## Important: Think Deeply
+
+When reviewing:
+1. **Think hard** about architectural implications
+2. Consider how changes affect the entire system
+3. Look for subtle bugs and edge cases
+4. Evaluate maintainability over time
+5. Consider extension developer experience
+6. Think about migration paths
+
+This is a COMPREHENSIVE review, not a linting pass. Provide the same quality feedback a senior engineer would give after careful consideration.
+
+## Phase 8: Track Review Metrics
+
+After completing the review, save metrics for analysis:
+
+```bash
+# Calculate review duration
+REVIEW_END_TIME=$(date +%s)
+REVIEW_DURATION=$((REVIEW_END_TIME - REVIEW_START_TIME))
+
+# Calculate total issues
+TOTAL_ISSUES=$((CRITICAL_COUNT + HIGH_COUNT + MEDIUM_COUNT + LOW_COUNT))
+
+# Create metrics directory if it doesn't exist
+METRICS_DIR=".claude/review-metrics"
+mkdir -p "$METRICS_DIR"
+
+# Generate metrics file
+METRICS_FILE="$METRICS_DIR/metrics-$(date +%Y%m).json"
+
+# Create or update monthly metrics file
+if [ -f "$METRICS_FILE" ]; then
+  # Append to existing file
+  jq -n \
+    --arg pr "$PR_NUMBER" \
+    --arg title "$PR_TITLE" \

+# Create Frontend Release
+
+This command guides you through creating a comprehensive frontend release with semantic versioning analysis, automated change detection, security scanning, and multi-stage human verification.
+
+<task>
+Create a frontend release with version type: $ARGUMENTS
+
+Expected format: Version increment type and optional description
+Examples:
+- `patch` - Bug fixes only
+- `minor` - New features, backward compatible  
+- `major` - Breaking changes
+- `prerelease` - Alpha/beta/rc releases
+- `patch "Critical security fixes"` - With custom description
+- `minor --skip-changelog` - Skip automated changelog generation
+- `minor --dry-run` - Simulate release without executing
+
+If no arguments provided, the command will always perform prerelease if the current version is prerelease, or patch in other cases. This command will never perform minor or major releases without explicit direction.
+</task>
+
+## Prerequisites
+
+Before starting, ensure:
+- You have push access to the repository
+- GitHub CLI (`gh`) is authenticated  
+- You're on a clean main branch working tree
+- All intended changes are merged to main
+- You understand the scope of changes being released
+
+## Critical Checks Before Starting
+
+### 1. Check Current Version Status
+```bash
+# Get current version and check if it's a pre-release
+CURRENT_VERSION=$(node -p "require('./package.json').version")
+if [[ "$CURRENT_VERSION" =~ ^[0-9]+\.[0-9]+\.[0-9]+- ]]; then
+  echo "⚠️  Current version $CURRENT_VERSION is a pre-release"
+  echo "Consider releasing stable (e.g., 1.24.0-1 → 1.24.0) first"
+fi
+```
+
+### 2. Find Last Stable Release
+```bash
+# Get last stable release tag (no pre-release suffix)
+LAST_STABLE=$(git tag -l "v*" | grep -v "\-" | sort -V | tail -1)
+echo "Last stable release: $LAST_STABLE"
+```
+
+## Configuration Options
+
+**Environment Variables:**
+- `RELEASE_SKIP_SECURITY_SCAN=true` - Skip security audit
+- `RELEASE_AUTO_APPROVE=true` - Skip some confirmation prompts
+- `RELEASE_DRY_RUN=true` - Simulate release without executing
+
+## Release Process
+
+### Step 1: Environment Safety Check
+
+1. Verify clean working directory:
+   ```bash
+   git status --porcelain
+   ```
+2. Confirm on main branch:
+   ```bash
+   git branch --show-current
+   ```
+3. Pull latest changes:
+   ```bash
+   git pull origin main
+   ```
+4. Check GitHub CLI authentication:
+   ```bash
+   gh auth status
+   ```
+5. Verify npm/PyPI publishing access (dry run)
+6. **CONFIRMATION REQUIRED**: Environment ready for release?
+
+### Step 2: Analyze Recent Changes
+
+1. Get current version from package.json
+2. **IMPORTANT**: Determine correct base for comparison:
+   ```bash
+   # If current version is pre-release, use last stable release
+   if [[ "$CURRENT_VERSION" =~ ^[0-9]+\.[0-9]+\.[0-9]+- ]]; then
+     BASE_TAG=$LAST_STABLE
+   else
+     BASE_TAG=$(git describe --tags --abbrev=0)
+   fi
+   ```
+3. Find commits since base release (CRITICAL: use --first-parent):
+   ```bash
+   git log ${BASE_TAG}..HEAD --oneline --no-merges --first-parent
+   ```
+4. Count total commits:
+   ```bash
+   COMMIT_COUNT=$(git log ${BASE_TAG}..HEAD --oneline --no-merges --first-parent | wc -l)
+   echo "Found $COMMIT_COUNT commits since $BASE_TAG"
+   ```
+5. Analyze commits for:
+   - Breaking changes (BREAKING CHANGE, !, feat())
+   - New features (feat:, feature:)
+   - Bug fixes (fix:, bugfix:)
+   - Documentation changes (docs:)
+   - Dependency updates
+6. **VERIFY PR TARGET BRANCHES**:
+   ```bash
+   # Get merged PRs and verify they were merged to main
+   gh pr list --state merged --limit 50 --json number,title,baseRefName,mergedAt | \
+     jq -r '.[] | select(.baseRefName == "main") | "\(.number): \(.title)"'
+   ```
+7. **HUMAN ANALYSIS**: Review change summary and verify scope
+
+### Step 3: Version Preview
+
+**Version Preview:**
+- Current: `${CURRENT_VERSION}`
+- Proposed: Show exact version number
+- **CONFIRMATION REQUIRED**: Proceed with version `X.Y.Z`?
+
+### Step 4: Security and Dependency Audit
+
+1. Run security audit:
+   ```bash
+   npm audit --audit-level moderate
+   ```
+2. Check for known vulnerabilities in dependencies
+3. Scan for hardcoded secrets or credentials:
+   ```bash
+   git log -p ${BASE_TAG}..HEAD | grep -iE "(password|key|secret|token)" || echo "No sensitive data found"
+   ```
+4. Verify no sensitive data in recent commits
+5. **SECURITY REVIEW**: Address any critical findings before proceeding?
+
+### Step 5: Pre-Release Testing
+
+1. Run complete test suite:
+   ```bash
+   npm run test:unit
+   npm run test:component  
+   npm run test:browser
+   ```
+2. Run type checking:
+   ```bash
+   npm run typecheck
+   ```
+3. Run linting (may have issues with missing packages):
+   ```bash
+   npm run lint || echo "Lint issues - verify if critical"
+   ```
+4. Test build process:
+   ```bash
+   npm run build
+   npm run build:types
+   ```
+5. **QUALITY GATE**: All tests and builds passing?
+
+### Step 6: Breaking Change Analysis
+
+1. Analyze API changes in:
+   - Public TypeScript interfaces
+   - Extension APIs
+   - Component props
+   - CLAUDE.md guidelines
+2. Check for:
+   - Removed public functions/classes
+   - Changed function signatures
+   - Deprecated feature removals
+   - Configuration changes
+3. Generate breaking change summary
+4. **COMPATIBILITY REVIEW**: Breaking changes documented and justified?
+
+### Step 7: Generate and Save Changelog
+
+1. Extract commit messages since base release:
+   ```bash
+   git log ${BASE_TAG}..HEAD --oneline --no-merges --first-parent > commits.txt
+   ```
+2. **CRITICAL**: Verify PR inclusion by checking merge location:
+   ```bash
+   # For each significant PR mentioned, verify it's on main
+   for PR in ${SIGNIFICANT_PRS}; do
+     COMMIT=$(gh pr view $PR --json mergeCommit -q .mergeCommit.oid)
+     git branch -r --contains $COMMIT | grep -q "origin/main" || \
+       echo "WARNING: PR #$PR not on main branch!"
+   done
+   ```
+3. Group by type:
+   - 🚀 **Features** (feat:)
+   - 🐛 **Bug Fixes** (fix:)
+   - 💥 **Breaking Changes** (BREAKING CHANGE)
+   - 📚 **Documentation** (docs:)
+   - 🔧 **Maintenance** (chore:, refactor:)
+   - ⬆️ **Dependencies** (deps:, dependency updates)
+4. Include PR numbers and links
+5. Add issue references (Fixes #123)
+6. **Save changelog locally:**
+   ```bash
+   # Save to dated file for history
+   echo "$CHANGELOG" > release-notes-${NEW_VERSION}-$(date +%Y%m%d).md
+   
+   # Save to current for easy access
+   echo "$CHANGELOG" > CURRENT_RELEASE_NOTES.md
+   ```
+7. **CHANGELOG REVIEW**: Verify all PRs listed are actually on main branch
+
+### Step 8: Create Enhanced Release Notes
+
+1. Create comprehensive user-facing release notes including:
+   - **What's New**: Major features and improvements
+   - **Bug Fixes**: User-visible fixes
+   - **Breaking Changes**: Migration guide if applicable
+   - **Dependencies**: Major dependency updates
+   - **Performance**: Notable performance improvements
+   - **Contributors**: Thank contributors for their work
+2. Reference related documentation updates
+3. Include screenshots for UI changes (if available)
+4. **Save release notes:**
+   ```bash
+   # Enhanced release notes for GitHub
+   echo "$RELEASE_NOTES" > github-release-notes-${NEW_VERSION}.md
+   ```
+5. **CONTENT REVIEW**: Release notes clear and helpful for users?
+
+### Step 9: Create Version Bump PR
+
+**For standard version bumps (patch/minor/major):**
+```bash
+# Trigger the workflow
+gh workflow run version-bump.yaml -f version_type=${VERSION_TYPE}
+
+# Workflow runs quickly - usually creates PR within 30 seconds
+echo "Workflow triggered. Waiting for PR creation..."
+```
+
+**For releasing a stable version:**
+1. Must manually create branch and update version:
+   ```bash
+   git checkout -b version-bump-${NEW_VERSION}
+   # Edit package.json to remove pre-release suffix
+   git add package.json
+   git commit -m "${NEW_VERSION}"
+   git push origin version-bump-${NEW_VERSION}
+   ```
+
+2. Wait for PR creation (if using workflow) or create manually:
+   ```bash
+   # For workflow-created PRs - wait and find it
+   sleep 30
+   # Look for PR from comfy-pr-bot (not github-actions)
+   PR_NUMBER=$(gh pr list --author comfy-pr-bot --limit 1 --json number --jq '.[0].number')
+   
+   # Verify we got the PR
+   if [ -z "$PR_NUMBER" ]; then
+     echo "PR not found yet. Checking recent PRs..."
+     gh pr list --limit 5 --json number,title,author
+   fi
+   
+   # For manual PRs
+   gh pr create --title "${NEW_VERSION}" \
+     --body-file enhanced-pr-description.md \
+     --label "Release"
+   ```
+3. **Create enhanced PR description:**
+   ```bash
+   cat > enhanced-pr-description.md << EOF
+   # Release v${NEW_VERSION}
+
+   ## Version Change
+   \`${CURRENT_VERSION}\` → \`${NEW_VERSION}\` (${VERSION_TYPE})
+
+   ## Changelog
+   ${CHANGELOG}
+
+   ## Breaking Changes
+   ${BREAKING_CHANGES}
+
+   ## Testing Performed
+   - ✅ Full test suite (unit, component, browser)
+   - ✅ TypeScript compilation
+   - ✅ Linting checks
+   - ✅ Build verification
+   - ✅ Security audit
+
+   ## Distribution Channels
+   - GitHub Release (with dist.zip)
+   - PyPI Package (comfyui-frontend-package)
+   - npm Package (@comfyorg/comfyui-frontend-types)
+
+   ## Post-Release Tasks
+   - [ ] Verify all distribution channels
+   - [ ] Update external documentation
+   - [ ] Monitor for issues
+   EOF
+   ```
+4. Update PR with enhanced description:
+   ```bash
+   gh pr edit ${PR_NUMBER} --body-file enhanced-pr-description.md
+   ```
+5. Add changelog as comment for easy reference:
+   ```bash
+   gh pr comment ${PR_NUMBER} --body-file CURRENT_RELEASE_NOTES.md
+   ```
+6. **PR REVIEW**: Version bump PR created and enhanced correctly?
+
+### Step 11: Critical Release PR Verification
+
+1. **CRITICAL**: Verify PR has "Release" label:
+   ```bash
+   gh pr view ${PR_NUMBER} --json labels | jq -r '.labels[].name' | grep -q "Release" || \
+     echo "ERROR: Release label missing! Add it immediately!"
+   ```
+2. Check for update-locales commits:
+   ```bash
+   # WARNING: update-locales may add [skip ci] which blocks release workflow!
+   gh pr view ${PR_NUMBER} --json commits | grep -q "skip ci" && \
+     echo "WARNING: [skip ci] detected - release workflow may not trigger!"
+   ```
+3. Verify version number in package.json
+4. Review all changed files
+5. Ensure no unintended changes included
+6. Wait for required PR checks:
+   ```bash
+   gh pr checks ${PR_NUMBER} --watch
+   ```
+7. **FINAL CODE REVIEW**: Release label present and no [skip ci]?
+
+### Step 12: Pre-Merge Validation
+
+1. **Review Requirements**: Release PRs require approval
+2. Monitor CI checks - watch for update-locales
+3. **CRITICAL WARNING**: If update-locales adds [skip ci], the release workflow won't trigger!
+4. Check no new commits to main since PR creation
+5. **DEPLOYMENT READINESS**: Ready to merge?
+
+### Step 13: Execute Release
+
+1. **FINAL CONFIRMATION**: Merge PR to trigger release?
+2. Merge the Release PR:
+   ```bash
+   gh pr merge ${PR_NUMBER} --merge
+   ```
+3. **IMMEDIATELY CHECK**: Did release workflow trigger?
+   ```bash
+   sleep 10
+   gh run list --workflow=release.yaml --limit=1
+   ```
+4. If workflow didn't trigger due to [skip ci]:
+   ```bash
+   echo "ERROR: Release workflow didn't trigger!"
+   echo "Options:"
+   echo "1. Create patch release (e.g., 1.24.1) to trigger workflow"
+   echo "2. Investigate manual release options"
+   ```
+5. If workflow triggered, monitor execution:
+   ```bash
+   WORKFLOW_RUN_ID=$(gh run list --workflow=release.yaml --limit=1 --json databaseId --jq '.[0].databaseId')
+   gh run watch ${WORKFLOW_RUN_ID}
+   ```
+
+### Step 14: Enhance GitHub Release
+
+1. Wait for automatic release creation:
+   ```bash
+   # Wait for release to be created
+   while ! gh release view v${NEW_VERSION} >/dev/null 2>&1; do
+     echo "Waiting for release creation..."
+     sleep 10
+   done
+   ```
+
+2. **Enhance the GitHub release:**
+   ```bash
+   # Update release with our enhanced notes
+   gh release edit v${NEW_VERSION} \
+     --title "🚀 ComfyUI Frontend v${NEW_VERSION}" \
+     --notes-file github-release-notes-${NEW_VERSION}.md \
+     --latest
+   
+   # Add any additional assets if needed
+   # gh release upload v${NEW_VERSION} additional-assets.zip
+   ```
+
+3. **Verify release details:**
+   ```bash
+   gh release view v${NEW_VERSION}
+   ```
+
+### Step 15: Verify Multi-Channel Distribution
+
+1. **GitHub Release:**
+   ```bash
+   gh release view v${NEW_VERSION} --json assets,body,createdAt,tagName
+   ```
+   - ✅ Check release notes
+   - ✅ Verify dist.zip attachment
+   - ✅ Confirm release marked as latest (for main branch)
+
+2. **PyPI Package:**
+   ```bash
+   # Check PyPI availability (may take a few minutes)
+   for i in {1..10}; do
+     if curl -s https://pypi.org/pypi/comfyui-frontend-package/json | jq -r '.releases | keys[]' | grep -q ${NEW_VERSION}; then
+       echo "✅ PyPI package available"
+       break
+     fi
+     echo "⏳ Waiting for PyPI package... (attempt $i/10)"
+     sleep 30
+   done
+   ```
+
+3. **npm Package:**
+   ```bash
+   # Check npm availability
+   for i in {1..10}; do
+     if npm view @comfyorg/comfyui-frontend-types@${NEW_VERSION} version >/dev/null 2>&1; then
+       echo "✅ npm package available"
+       break
+     fi
+     echo "⏳ Waiting for npm package... (attempt $i/10)"
+     sleep 30
+   done
+   ```
+
+4. **DISTRIBUTION VERIFICATION**: All channels published successfully?
+
+### Step 16: Post-Release Monitoring Setup
+
+1. **Monitor immediate release health:**
+   ```bash
+   # Check for immediate issues
+   gh issue list --label "bug" --state open --limit 5 --json title,number,createdAt
+   
+   # Monitor download metrics (if accessible)
+   gh release view v${NEW_VERSION} --json assets --jq '.assets[].downloadCount'
+   ```
+
+2. **Update documentation tracking:**
+   ```bash
+   cat > post-release-checklist.md << EOF
+   # Post-Release Checklist for v${NEW_VERSION}
+
+   ## Immediate Tasks (Next 24 hours)
+   - [ ] Monitor error rates and user feedback
+   - [ ] Watch for critical issues
+   - [ ] Verify documentation is up to date
+   - [ ] Check community channels for questions
+
+   ## Short-term Tasks (Next week)
+   - [ ] Update external integration guides
+   - [ ] Monitor adoption metrics
+   - [ ] Gather user feedback
+   - [ ] Plan next release cycle
+
+   ## Long-term Tasks
+   - [ ] Analyze release process improvements
+   - [ ] Update release templates based on learnings
+   - [ ] Document any new patterns discovered
+
+   ## Key Metrics to Track
+   - Download counts: GitHub, PyPI, npm
+   - Issue reports related to v${NEW_VERSION}
+   - Community feedback and adoption
+   - Performance impact measurements
+   EOF
+   ```
+
+3. **Create release summary:**
+   ```bash
+   cat > release-summary-${NEW_VERSION}.md << EOF
+   # Release Summary: ComfyUI Frontend v${NEW_VERSION}
+
+   **Released:** $(date)
+   **Type:** ${VERSION_TYPE}
+   **Duration:** ~${RELEASE_DURATION} minutes
+   **Release Commit:** ${RELEASE_COMMIT}
+
+   ## Metrics
+   - **Commits Included:** ${COMMITS_COUNT}
+   - **Contributors:** ${CONTRIBUTORS_COUNT}
+   - **Files Changed:** ${FILES_CHANGED}
+   - **Lines Added/Removed:** +${LINES_ADDED}/-${LINES_REMOVED}
+
+   ## Distribution Status
+   - ✅ GitHub Release: Published
+   - ✅ PyPI Package: Available
+   - ✅ npm Types: Available
+
+   ## Next Steps
+   - Monitor for 24-48 hours
+   - Address any critical issues immediately
+   - Plan next release cycle
+
+   ## Files Generated
+   - \`release-notes-${NEW_VERSION}-$(date +%Y%m%d).md\` - Detailed changelog
+   - \`github-release-notes-${NEW_VERSION}.md\` - GitHub release notes
+   - \`post-release-checklist.md\` - Follow-up tasks
+   EOF
+   ```
+
+4. **RELEASE COMPLETION**: All post-release setup completed?
+
+## Advanced Safety Features
+
+### Rollback Procedures
+
+**Pre-Merge Rollback:**
+```bash
+# Close version bump PR and reset
+gh pr close ${PR_NUMBER}
+git reset --hard origin/main
+git clean -fd
+```
+
+**Post-Merge Rollback:**
+```bash
+# Create immediate patch release with reverts
+git revert ${RELEASE_COMMIT}
+# Follow this command again with patch version
+```
+
+**Emergency Procedures:**
+```bash
+# Document incident
+cat > release-incident-${NEW_VERSION}.md << EOF
+# Release Incident Report
+
+**Version:** ${NEW_VERSION}
+**Issue:** [Describe the problem]
+**Impact:** [Severity and scope]
+**Resolution:** [Steps taken]
+**Prevention:** [Future improvements]
+EOF
+
+# Contact package registries for critical issues
+echo "For critical security issues, consider:"
+echo "- PyPI: Contact support for package yanking"
+echo "- npm: Use 'npm unpublish' within 72 hours"
+echo "- GitHub: Update release with warning notes"
+```
+

+6. **📊 Monitoring Gate**: Post-release health tracking
+
+## Common Scenarios
+
+### Scenario 1: Regular Feature Release
+```bash
+/project:create-frontend-release minor
+```
+- Analyzes features since last release
+- Generates changelog automatically
+- Creates comprehensive release notes
+
+### Scenario 2: Critical Security Patch
+```bash
+/project:create-frontend-release patch "Security fixes for CVE-2024-XXXX"
+```
+- Expedited security scanning
+- Enhanced monitoring setup
+
+### Scenario 3: Major Version with Breaking Changes
+```bash
+/project:create-frontend-release major
+```
+- Comprehensive breaking change analysis
+- Migration guide generation
+
+### Scenario 4: Pre-release Testing
+```bash
+/project:create-frontend-release prerelease
+```
+- Creates alpha/beta/rc versions
+- Draft release status
+- Python package specs require that prereleases use alpha/beta/rc as the preid
+
+## Common Issues and Solutions
+
+### Issue: Pre-release Version Confusion
+**Problem**: Not sure whether to promote pre-release or create new version
+**Solution**: 
+- Follow semver standards: a prerelease version is followed by a normal release.  It should have the same major, minor, and patch versions as the prerelease.
+
+### Issue: Wrong Commit Count
+**Problem**: Changelog includes commits from other branches
+**Solution**: Always use `--first-parent` flag with git log
+
+**Update**: Sometimes update-locales doesn't add [skip ci] - always verify!
+
+### Issue: Missing PRs in Changelog
+**Problem**: PR was merged to different branch
+**Solution**: Verify PR merge target with:
+```bash
+gh pr view ${PR_NUMBER} --json baseRefName
+```
+
+### Issue: Release Failed Due to [skip ci]
+**Problem**: Release workflow didn't trigger after merge
+**Prevention**: Always avoid this scenario
+- Ensure that `[skip ci]` or similar flags are NOT in the `HEAD` commit message of the PR
+  - Push a new, empty commit to the PR
+- Always double-check this immediately before merging
+
+**Recovery Strategy**:
+1. Revert version in a new PR (e.g., 1.24.0 → 1.24.0-1)
+2. Merge the revert PR
+3. Run version bump workflow again
+4. This creates a fresh PR without [skip ci]
+Benefits: Cleaner than creating extra version numbers
+
+## Key Learnings & Notes
+
+1. **PR Author**: Version bump PRs are created by `comfy-pr-bot`, not `github-actions`
+2. **Workflow Speed**: Version bump workflow typically completes in ~20-30 seconds
+3. **Update-locales Behavior**: Inconsistent - sometimes adds [skip ci], sometimes doesn't

+# Create Hotfix Release
+
+This command guides you through creating a patch/hotfix release for ComfyUI Frontend with comprehensive safety checks and human confirmations at each step.
+
+<task>
+Create a hotfix release by cherry-picking commits or PR commits from main to a core branch: $ARGUMENTS
+
+Expected format: Comma-separated list of commits or PR numbers
+Examples: 
+- `abc123,def456,ghi789` (commits)
+- `#1234,#5678` (PRs)
+- `abc123,#1234,def456` (mixed)
+
+If no arguments provided, the command will help identify the correct core branch and guide you through selecting commits/PRs.
+</task>
+
+## Prerequisites
+
+Before starting, ensure:
+- You have push access to the repository
+- GitHub CLI (`gh`) is authenticated
+- You're on a clean working tree
+- You understand the commits/PRs you're cherry-picking
+
+## Hotfix Release Process
+
+### Step 1: Identify Target Core Branch
+
+1. Fetch the current ComfyUI requirements.txt from master branch:
+   ```bash
+   curl -s https://raw.githubusercontent.com/comfyanonymous/ComfyUI/master/requirements.txt | grep "comfyui-frontend-package"
+   ```
+2. Extract the `comfyui-frontend-package` version (e.g., `comfyui-frontend-package==1.23.4`)
+3. Parse version to get major.minor (e.g., `1.23.4` → `1.23`)
+4. Determine core branch: `core/<major>.<minor>` (e.g., `core/1.23`)
+5. Verify the core branch exists: `git ls-remote origin refs/heads/core/*`
+6. **CONFIRMATION REQUIRED**: Is `core/X.Y` the correct target branch?
+
+### Step 2: Parse and Validate Arguments
+
+1. Parse the comma-separated list of commits/PRs
+2. For each item:
+   - If starts with `#`: Treat as PR number
+   - Otherwise: Treat as commit hash
+3. For PR numbers:
+   - Fetch PR details using `gh pr view <number>`
+   - Extract the merge commit if PR is merged
+   - If PR has multiple commits, list them all
+   - **CONFIRMATION REQUIRED**: Use merge commit or cherry-pick individual commits?
+4. Validate all commit hashes exist in the repository
+
+### Step 3: Analyze Target Changes
+
+1. For each commit/PR to cherry-pick:
+   - Display commit hash, author, date
+   - Show PR title and number (if applicable)
+   - Display commit message
+   - Show files changed and diff statistics
+   - Check if already in core branch: `git branch --contains <commit>`
+2. Identify potential conflicts by checking changed files
+3. **CONFIRMATION REQUIRED**: Proceed with these commits?
+
+### Step 4: Create Hotfix Branch
+
+1. Checkout the core branch (e.g., `core/1.23`)
+2. Pull latest changes: `git pull origin core/X.Y`
+3. Display current version from package.json
+4. Create hotfix branch: `hotfix/<version>-<timestamp>`
+   - Example: `hotfix/1.23.4-20241120`
+5. **CONFIRMATION REQUIRED**: Created branch correctly?
+
+### Step 5: Cherry-pick Changes
+
+For each commit:
+1. Attempt cherry-pick: `git cherry-pick <commit>`
+2. If conflicts occur:
+   - Display conflict details
+   - Show conflicting sections
+   - Provide resolution guidance
+   - **CONFIRMATION REQUIRED**: Conflicts resolved correctly?
+3. After successful cherry-pick:
+   - Show the changes: `git show HEAD`
+   - Run validation: `npm run typecheck && npm run lint`
+4. **CONFIRMATION REQUIRED**: Cherry-pick successful and valid?
+
+### Step 6: Create PR to Core Branch
+
+1. Push the hotfix branch: `git push origin hotfix/<version>-<timestamp>`
+2. Create PR using gh CLI:
+   ```bash
+   gh pr create --base core/X.Y --head hotfix/<version>-<timestamp> \
+     --title "[Hotfix] Cherry-pick fixes to core/X.Y" \
+     --body "Cherry-picked commits: ..."
+   ```
+3. Add appropriate labels (but NOT "Release" yet)
+4. PR body should include:
+   - List of cherry-picked commits/PRs
+   - Original issue references
+   - Testing instructions
+   - Impact assessment
+5. **CONFIRMATION REQUIRED**: PR created correctly?
+
+### Step 7: Wait for Tests
+
+1. Monitor PR checks: `gh pr checks`
+2. Display test results as they complete
+3. If any tests fail:
+   - Show failure details
+   - Analyze if related to cherry-picks
+   - **DECISION REQUIRED**: Fix and continue, or abort?
+4. Wait for all required checks to pass
+5. **CONFIRMATION REQUIRED**: All tests passing?
+
+### Step 8: Merge Hotfix PR
+
+1. Verify all checks have passed
+2. Check for required approvals
+3. Merge the PR: `gh pr merge --merge`
+4. Delete the hotfix branch
+5. **CONFIRMATION REQUIRED**: PR merged successfully?
+
+### Step 9: Create Version Bump
+
+1. Checkout the core branch: `git checkout core/X.Y`
+2. Pull latest changes: `git pull origin core/X.Y`
+3. Read current version from package.json
+4. Determine patch version increment:
+   - Current: `1.23.4` → New: `1.23.5`
+5. Create release branch named with new version: `release/1.23.5`
+6. Update version in package.json to `1.23.5`
+7. Commit: `git commit -m "[release] Bump version to 1.23.5"`
+8. **CONFIRMATION REQUIRED**: Version bump correct?
+
+### Step 10: Create Release PR
+
+1. Push release branch: `git push origin release/1.23.5`
+2. Create PR with Release label:
+   ```bash
+   gh pr create --base core/X.Y --head release/1.23.5 \
+     --title "[Release] v1.23.5" \
+     --body "..." \
+     --label "Release"
+   ```
+3. **CRITICAL**: Verify "Release" label is added
+4. PR description should include:
+   - Version: `1.23.4` → `1.23.5`
+   - Included fixes (link to previous PR)
+   - Release notes for users
+5. **CONFIRMATION REQUIRED**: Release PR has "Release" label?
+
+### Step 11: Monitor Release Process
+
+1. Wait for PR checks to pass
+2. **FINAL CONFIRMATION**: Ready to trigger release by merging?
+3. Merge the PR: `gh pr merge --merge`
+4. Monitor release workflow:
+   ```bash
+   gh run list --workflow=release.yaml --limit=1
+   gh run watch
+   ```
+5. Track progress:
+   - GitHub release draft/publication
+   - PyPI upload
+   - npm types publication
+
+### Step 12: Post-Release Verification
+
+1. Verify GitHub release:
+   ```bash
+   gh release view v1.23.5
+   ```
+2. Check PyPI package:
+   ```bash
+   pip index versions comfyui-frontend-package | grep 1.23.5
+   ```
+3. Verify npm package:
+   ```bash
+   npm view @comfyorg/comfyui-frontend-types@1.23.5
+   ```
+4. Generate release summary with:
+   - Version released
+   - Commits included
+   - Issues fixed
+   - Distribution status
+5. **CONFIRMATION REQUIRED**: Release completed successfully?
+
+## Safety Checks
+
+Throughout the process:
+- Always verify core branch matches ComfyUI's requirements.txt
+- For PRs: Ensure using correct commits (merge vs individual)
+- Check version numbers follow semantic versioning
+- **Critical**: "Release" label must be on version bump PR
+- Validate cherry-picks don't break core branch stability
+- Keep audit trail of all operations
+
+## Rollback Procedures
+
+If something goes wrong:
+- Before push: `git reset --hard origin/core/X.Y`
+- After PR creation: Close PR and start over
+- After failed release: Create new patch version with fixes
+- Document any issues for future reference
+
+## Important Notes
+
+- Core branch version will be behind main - this is expected
+- The "Release" label triggers the PyPI/npm publication
+- PR numbers must include the `#` prefix
+- Mixed commits/PRs are supported but review carefully
+- Always wait for full test suite before proceeding
+
+## Expected Timeline
+
+- Step 1-3: ~10 minutes (analysis)
+- Steps 4-6: ~15-30 minutes (cherry-picking)
+- Step 7: ~10-20 minutes (tests)
+- Steps 8-10: ~10 minutes (version bump)
+- Step 11-12: ~15-20 minutes (release)
+- Total: ~60-90 minutes
+
+This process ensures a safe, verified hotfix release with multiple confirmation points and clear tracking of what changes are being released.

+Your task is to perform visual verification of our recent changes to ensure they display correctly in the browser. This verification is critical for catching visual regressions, layout issues, and ensuring our UI changes render properly for end users.
+
+<instructions>
+Follow these steps systematically to verify our changes:
+
+1. **Server Setup**
+   - Check if the dev server is running on port 5173 using browser navigation or port checking
+   - If not running, start it with `npm run dev` from the root directory
+   - If the server fails to start, provide detailed troubleshooting steps by reading package.json and README.md for accurate instructions
+   - Wait for the server to be fully ready before proceeding
+
+2. **Visual Testing Process**
+   - Navigate to http://localhost:5173/
+   - For each target page (specified in arguments or recently changed files):
+     * Navigate to the page using direct URL or site navigation
+     * Take a high-quality screenshot
+     * Analyze the screenshot for the specific changes we implemented
+     * Document any visual issues or improvements needed
+
+3. **Quality Verification**
+   Check each page for:
+   - Content accuracy and completeness
+   - Proper styling and layout alignment
+   - Responsive design elements
+   - Navigation functionality
+   - Image loading and display
+   - Typography and readability
+   - Color scheme consistency
+   - Interactive elements (buttons, links, forms)
+</instructions>
+
+<examples>
+Common issues to watch for:
+- Broken layouts or overlapping elements
+- Missing images or broken image links
+- Inconsistent styling or spacing
+- Navigation menu problems
+- Mobile responsiveness issues
+- Text overflow or truncation
+- Color contrast problems
+</examples>
+
+<reporting>
+For each page tested, provide:
+1. Page URL and screenshot
+2. Confirmation that changes display correctly OR detailed description of issues found
+3. Any design improvement suggestions
+4. Overall assessment of visual quality
+
+If you find issues, be specific about:
+- Exact location of the problem
+- Expected vs actual behavior
+- Severity level (critical, important, minor)
+- Suggested fix if obvious
+</reporting>
+
+Remember: Take your time with each screenshot and analysis. Visual quality directly impacts user experience and our project's professional appearance.

+
+## Quick Reference
+
+### PrimeVue Component Migrations
+
+When reviewing, flag these deprecated components:
+- `Dropdown` → Use `Select` from 'primevue/select'
+- `OverlayPanel` → Use `Popover` from 'primevue/popover'
+- `Calendar` → Use `DatePicker` from 'primevue/datepicker'
+- `InputSwitch` → Use `ToggleSwitch` from 'primevue/toggleswitch'
+- `Sidebar` → Use `Drawer` from 'primevue/drawer'
+- `Chips` → Use `AutoComplete` with multiple enabled and typeahead disabled
+- `TabMenu` → Use `Tabs` without panels
+- `Steps` → Use `Stepper` without panels
+- `InlineMessage` → Use `Message` component
+
+### API Utilities Reference
+
+- `api.apiURL()` - Backend API calls (/prompt, /queue, /view, etc.)
+- `api.fileURL()` - Static file access (templates, extensions)
+- `$t()` / `i18n.global.t()` - Internationalization
+- `DOMPurify.sanitize()` - HTML sanitization
+
+## Review Scope
+
+This automated review performs comprehensive analysis including:
+- Architecture and design patterns
+- Security vulnerabilities
+- Performance implications
+- Code quality and maintainability
+- Integration concerns
+
+For implementation details, see `.claude/commands/comprehensive-pr-review.md`.

+
+#### Playwright Browser Automation
+
+The Playwright MCP server enables LLM coding assistants (like Copilot, Claude Code, etc.) to control and inspect web browsers programmatically. This allows assistants to navigate websites, take screenshots, and interact with web pages on your behalf.
+
+For ComfyUI_frontend development, you can ask coding assistants to use Playwright screenshots to continuously verify that your code changes produce the expected visual results.
+
+##### Setup for Claude Code
+
+After installing dependencies with `npm i`, the Playwright MCP server will be automatically available when you start Claude Code locally.
+
+Here's how Claude Code can use the Playwright MCP server to inspect the interface of the local development server (assuming you're running the dev server at `localhost:5173`):

-### Debugging Custom Node (Extension) Issues
-
-If you're experiencing crashes, errors, or unexpected behavior with ComfyUI, it's often caused by custom nodes (extensions). Follow these steps to identify and resolve the issues:
-
-#### Step 1: Verify if custom nodes are causing the problem
-
-Run ComfyUI with the `--disable-all-custom-nodes` flag:
-
-```bash
-python main.py --disable-all-custom-nodes
-```
-
-If the issue disappears, a custom node is the culprit. Proceed to the next step.
-
-#### Step 2: Identify the problematic custom node using binary search
-
-Rather than disabling nodes one by one, use this more efficient approach:
-
-1. Temporarily move half of your custom nodes out of the `custom_nodes` directory
-   ```bash
-   # Create a temporary directory
-   # Linux/Mac
-   mkdir ~/custom_nodes_disabled
-   
-   # Windows
-   mkdir %USERPROFILE%\custom_nodes_disabled
-   
-   # Move half of your custom nodes (assuming you have node1 through node8)
-   # Linux/Mac
-   mv custom_nodes/node1 custom_nodes/node2 custom_nodes/node3 custom_nodes/node4 ~/custom_nodes_disabled/
-   
-   # Windows
-   move custom_nodes\node1 custom_nodes\node2 custom_nodes\node3 custom_nodes\node4 %USERPROFILE%\custom_nodes_disabled\
-   ```
-
-2. Run ComfyUI again
-   - If the issue persists: The problem is in nodes 5-8 (the remaining half)
-   - If the issue disappears: The problem is in nodes 1-4 (the moved half)
-
-3. Let's assume the issue disappeared, so the problem is in nodes 1-4. Move half of these for the next test:
-   ```bash
-   # Move nodes 3-4 back to custom_nodes
-   # Linux/Mac
-   mv ~/custom_nodes_disabled/node3 ~/custom_nodes_disabled/node4 custom_nodes/
-   
-   # Windows
-   move %USERPROFILE%\custom_nodes_disabled\node3 %USERPROFILE%\custom_nodes_disabled\node4 custom_nodes\
-   ```
-
-4. Run ComfyUI again
-   - If the issue reappears: The problem is in nodes 3-4
-   - If issue still gone: The problem is in nodes 1-2
-
-5. Let's assume the issue reappeared, so the problem is in nodes 3-4. Test each one:
-   ```bash
-   # Move node 3 back to disabled
-   # Linux/Mac
-   mv custom_nodes/node3 ~/custom_nodes_disabled/
-   
-   # Windows
-   move custom_nodes\node3 %USERPROFILE%\custom_nodes_disabled\
-   ```
-
-6. Run ComfyUI again
-   - If the issue disappears: node3 is the problem
-   - If issue persists: node4 is the problem
-
-7. Repeat until you identify the specific problematic node
-
-#### Step 3: Update or replace the problematic node
-
-Once identified:
-1. Check for updates to the problematic custom node
-2. Consider alternatives with similar functionality
-3. Report the issue to the custom node developer with specific details
-
-### Common Issues and Solutions
-
-- **"Module not found" errors**: Usually indicates missing Python dependencies. Check the custom node's `requirements.txt` file for required packages and install them:
-  ```bash
-  pip install -r custom_nodes/problematic_node/requirements.txt
-  ```
-
-- **Frontend or Templates Package Not Updated**: After updating ComfyUI via Git, ensure you update the frontend dependencies:
-  ```bash
-  pip install -r requirements.txt
-  ```
-
-- **Can't Find Custom Node**: Make sure to disable node validation in ComfyUI settings.
-
-- **Error Toast About Workflow Failing Validation**: Report the issue to the ComfyUI team. As a temporary workaround, disable workflow validation in settings.
-
-- **Login Issues When Not on Localhost**: Normal login is only available when accessing from localhost. If you're running ComfyUI via LAN, another domain, or headless, you can use our API key feature to authenticate. The API key lets you log in normally through the UI. Generate an API key at [platform.comfy.org/login](https://platform.comfy.org/login) and use it in the API Key field in the login dialog or with the `--api-key` command line argument. Refer to our [API Key Integration Guide](https://docs.comfy.org/essentials/comfyui-server/api-key-integration#integration-of-api-key-to-use-comfyui-api-nodes) for complete setup instructions.

 ### Multiple Tests
 If you are running Playwright tests in parallel or running the same test multiple times, the flag `--multi-user` must be added to the main ComfyUI process.
 
+### Release API Mocking
+By default, all tests mock the release API (`api.comfy.org/releases`) to prevent release notification popups from interfering with test execution. This is necessary because the release notifications can appear over UI elements and block test interactions.
+
+To test with real release data, you can disable mocking:
