+          prompt: |
+            You are a professional i18n synchronization engineer for the Dify project.
+            Your task is to keep all language translations in sync with the English source (en-US).
+
+            ## Context
+            - Changed/target files: ${{ steps.detect_changes.outputs.CHANGED_FILES }}
+            - Target languages (empty means all supported): ${{ steps.detect_changes.outputs.TARGET_LANGS }}
+            - Sync mode: ${{ steps.detect_changes.outputs.SYNC_MODE }}
+            - Translation files are located in: web/i18n/{locale}/{filename}.json
+            - Language configuration is in: web/i18n-config/languages.ts
+            - Git diff is available: ${{ steps.detect_changes.outputs.DIFF_AVAILABLE }}
+
+            ## CRITICAL DESIGN: Verify First, Then Sync
+
+            You MUST follow this three-phase approach:
+
+            ═══════════════════════════════════════════════════════════════
+            ║  PHASE 1: VERIFY - Analyze and Generate Change Report       ║
+            ═══════════════════════════════════════════════════════════════
+
+            ### Step 1.1: Analyze Git Diff (for incremental mode)
+            ```bash
+            cat /tmp/i18n-diff.txt 2>/dev/null || echo "No diff available"
+            ```
+
+            Parse the diff to categorize changes:
+            - Lines with `+` (not `+++`): Added or modified values
+            - Lines with `-` (not `---`): Removed or old values
+            - Identify specific keys for each category:
+              * ADD: Keys that appear only in `+` lines (new keys)
+              * UPDATE: Keys that appear in both `-` and `+` lines (value changed)
+              * DELETE: Keys that appear only in `-` lines (removed keys)
+
+            ### Step 1.2: Read Language Configuration
+            ```bash
+            cat web/i18n-config/languages.ts
+            ```
+            Extract all languages with `supported: true`.
+
+            ### Step 1.3: Run i18n:check for Each Language
+            ```bash
+            cd web && pnpm install --frozen-lockfile
+            pnpm run i18n:check
+            ```
+
+            This will report:
+            - Missing keys (need to ADD)
+            - Extra keys (need to DELETE)
+
+            ### Step 1.4: Generate Change Report
+
+            Create a structured report identifying:
+            ```

+            ╚══════════════════════════════════════════════════════════════╝
+            ```
+
+            **IMPORTANT**: For UPDATE detection, compare git diff to find keys where
+            the English value changed. These MUST be re-translated even if target
+            language already has a translation (it's now stale!).
+
+            ═══════════════════════════════════════════════════════════════
+            ║  PHASE 2: SYNC - Execute Changes Based on Report            ║
+            ═══════════════════════════════════════════════════════════════
+
+            ### Step 2.1: Process ADD Operations
+            For each key in the ADD list:
+            1. Get the English value from en-US file
+            2. Translate to target language
+            3. Add to target language JSON file (maintain alphabetical order if file uses it)
+
+            ### Step 2.2: Process UPDATE Operations (CRITICAL!)
+            For each key in the UPDATE list:
+            1. Get the NEW English value
+            2. Translate to target language
+            3. **OVERWRITE** the existing translation (old one is stale!)
+
+            ### Step 2.3: Process DELETE Operations
+            For extra keys reported by i18n:check:
+            - Run: `cd web && pnpm run i18n:check --auto-remove`
+            - Or manually remove from target language JSON files
+
+            ## Translation Guidelines
+
+            - PRESERVE all placeholders exactly as-is:
+              - `{{variable}}` - Mustache interpolation
+              - `${variable}` - Template literal
+              - `<tag>content</tag>` - HTML tags
+              - `_one`, `_other` - Pluralization suffixes (these are KEY suffixes, not values)
+            - Use appropriate language register (formal/informal) based on existing translations
+            - Match existing translation style in each language
+            - Technical terms: check existing conventions per language
+            - For CJK languages: no spaces between characters unless necessary
+            - For RTL languages (ar-TN, fa-IR): ensure proper text handling
+
+            ## Output Format Requirements
+            - Alphabetical key ordering (if original file uses it)
+            - 2-space indentation
+            - Trailing newline at end of file
+            - Valid JSON (use proper escaping for special characters)
+
+            ═══════════════════════════════════════════════════════════════
+            ║  PHASE 3: RE-VERIFY - Confirm All Issues Resolved           ║
+            ═══════════════════════════════════════════════════════════════
+
+            ### Step 3.1: Run Lint Fix (IMPORTANT!)
+            ```bash
+            cd web && pnpm lint:fix --quiet -- 'i18n/**/*.json'
+            ```
+            This ensures:
+            - JSON keys are sorted alphabetically (jsonc/sort-keys rule)
+            - Valid i18n keys (dify-i18n/valid-i18n-keys rule)
+            - No extra keys (dify-i18n/no-extra-keys rule)
+
+            ### Step 3.2: Run Final i18n Check
+            ```bash
+            cd web && pnpm run i18n:check
+            ```
+
+            ### Step 3.3: Fix Any Remaining Issues
+            If check reports issues:
+            - Go back to PHASE 2 for unresolved items
+            - Repeat until check passes

+            ```
+
+            ## Mode-Specific Behavior
+
+            **SYNC_MODE = "incremental"** (default):
+            - Focus on keys identified from git diff
+            - Also check i18n:check output for any missing/extra keys
+            - Efficient for small changes
+
+            **SYNC_MODE = "full"**:
+            - Compare ALL keys between en-US and each language
+            - Run i18n:check to identify all discrepancies
+            - Use for first-time sync or fixing historical issues
+
+            ## Important Notes
+
+            1. Always run i18n:check BEFORE and AFTER making changes
+            2. The check script is the source of truth for missing/extra keys
+            3. For UPDATE scenario: git diff is the source of truth for changed values
+            4. Create a single commit with all translation changes
+            5. If any translation fails, continue with others and report failures
+
+            ═══════════════════════════════════════════════════════════════
+            ║  PHASE 4: COMMIT AND CREATE PR                              ║
+            ═══════════════════════════════════════════════════════════════
+
+            After all translations are complete and verified:
+
+            ### Step 4.1: Check for changes
+            ```bash
+            git status --porcelain
+            ```
+
+            If there are changes:
+
+            ### Step 4.2: Create a new branch and commit
+            ```bash
+            BRANCH_NAME="chore/i18n-sync-$(date +%Y%m%d-%H%M%S)"
+            git checkout -b "$BRANCH_NAME"
+            git add web/i18n/
+            git commit -m "chore(i18n): sync translations with en-US
+
+            - Synced translation files based on en-US changes
+            - Mode: ${{ steps.detect_changes.outputs.SYNC_MODE }}

+
+            🤖 Generated with Claude Code GitHub Action"
+            git push origin "$BRANCH_NAME"
+            ```
+
+            ### Step 4.3: Create Pull Request
+            ```bash
+            gh pr create \
+              --title "chore(i18n): sync translations with en-US" \

 ## Utility scripts
 
-- Auto-fill translations: `pnpm run i18n:gen --file app common --lang zh-Hans ja-JP [--dry-run]`
-  - Use space-separated values; repeat `--file` / `--lang` as needed. Defaults to all en-US files and all supported locales except en-US.
-  - Protects placeholders (`{{var}}`, `${var}`, `<tag>`) before translation and restores them after.
 - Check missing/extra keys: `pnpm run i18n:check --file app billing --lang zh-Hans [--auto-remove]`
   - Use space-separated values; repeat `--file` / `--lang` as needed. Returns non-zero on missing/extra keys; `--auto-remove` deletes extra keys automatically.
 
-Workflows: `.github/workflows/translate-i18n-base-on-english.yml` auto-runs the translation generator on `web/i18n/en-US/*.json` changes to main. `i18n:check` is a manual script (not run in CI).
+## Automatic Translation
+
+Translation is handled automatically by Claude Code GitHub Actions. When changes are pushed to `web/i18n/en-US/*.json` on the main branch:
+
+1. Claude Code analyzes the git diff to detect changes
+1. Identifies three types of changes:
+   - **ADD**: New keys that need translation
+   - **UPDATE**: Modified keys that need re-translation (even if target language has existing translation)
+   - **DELETE**: Removed keys that need to be deleted from other languages
+1. Runs `i18n:check` to verify the initial sync status.
+1. Translates missing/updated keys while preserving placeholders (`{{var}}`, `${var}`, `<tag>`) and removes deleted keys.
+1. Runs `lint:fix` to sort JSON keys and `i18n:check` again to ensure everything is synchronized.
+1. Creates a PR with the translations.
+
+### Manual Trigger
+
+To manually trigger translation:
+
+1. Go to Actions > "Translate i18n Files with Claude Code"
+1. Click "Run workflow"
+1. Optionally configure:
+   - **files**: Specific files to translate (space-separated, e.g., "app common")
+   - **languages**: Specific languages to translate (space-separated, e.g., "zh-Hans ja-JP")
+   - **mode**: `incremental` (default, only changes) or `full` (check all keys)
+
+Workflow: `.github/workflows/translate-i18n-claude.yml`
