+# Phase 2 Plan 2: FeishuResponseFormatter Summary
+
+**One-liner:** Feishu Card JSON 2.0 formatter with theme support, pagination markers, and interactive buttons.
+
+## What Was Done
+
+Created `FeishuResponseFormatter` class that formats responses as Feishu Card JSON 2.0 messages with three-zone structure (header/content/actions).
+
+### Task Summary
+
+| Task | Name | Status | Commit |
+|------|------|--------|--------|
+| 1 | Create test scaffold | DONE | 541437f |
+| 2 | Implement CardTheme and CardButton | DONE | d15ce81 |
+| 3 | Implement FeishuResponseFormatter | DONE | fbc69fc |
+
+### Files Created
+
+- `src/gsd_openclaw/response_formatter.py` - Response formatter implementation
+- `tests/test_response_formatter.py` - 6 unit tests
+
+## Key Implementation Details
+
+### CardTheme Enum
+- `SUCCESS = "green"` - Success operations
+- `ERROR = "red"` - Error responses
+- `INFO = "blue"` - Informational messages
+- `WARNING = "orange"` - Warning messages
+
+### CardButton Dataclass
+- `text: str` - Button label
+- `value: Dict[str, Any]` - Callback data
+- `button_type: str = "primary"` - Button style (primary/default/danger)
+
+### FeishuResponseFormatter Methods
+- `format_success(title, content, buttons=None)` - Green themed card
+- `format_error(title, content, buttons=None)` - Red themed card
+- `format_info(title, content, buttons=None)` - Blue themed card
+- `format_paginated(title, content, page, total_pages)` - Card with [N/M] marker
+
+### Card JSON Structure
+```json
+{
+  "schema": "2.0",
+  "config": {"wide_screen_mode": true},
+  "header": {
+    "title": {"tag": "plain_text", "content": "..."},
+    "template": "green"
+  },
+  "elements": [
+    {"tag": "div", "text": {"tag": "lark_md", "content": "..."}},
+    {"tag": "action", "actions": [...]}
+  ]
+}
+```
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Verification Results
+
+```
+pytest tests/test_response_formatter.py -v
+6 passed in 0.01s
+```
+
+All tests pass:
+- test_format_success_returns_valid_card
+- test_format_error_returns_red_theme
+- test_format_info_returns_blue_theme
+- test_format_with_buttons_includes_actions
+- test_format_paginated_adds_marker
+- test_card_has_required_structure
+
+## Integration Points
+
+- **Phase 3**: `orchestrator.py` will use `FeishuResponseFormatter` to format all responses before sending to Feishu
+- **OCLW-04 requirement**: Response formatting adapts to channel capabilities (markdown via lark_md)
+
+## Self-Check: PASSED
+
+- [x] `src/gsd_openclaw/response_formatter.py` exists
+- [x] `tests/test_response_formatter.py` exists
+- [x] Commit 541437f exists (test scaffold)
+- [x] Commit d15ce81 exists (CardTheme/CardButton)
+- [x] Commit fbc69fc exists (FeishuResponseFormatter)
+- [x] All 6 tests pass
