 ## Recent Improvements
 
+### Modern CLI for PRD Import (v0.9.8)
+- Modernized `ralph_import.sh` to use Claude Code CLI JSON output format
+  - Added `--output-format json` flag for structured responses
+  - Implemented `detect_response_format()` for JSON vs text detection
+  - Implemented `parse_conversion_response()` for extracting JSON fields
+- Enhanced error handling with structured JSON error messages
+  - Extracts `error_message` and `error_code` from JSON metadata
+  - Provides specific, actionable feedback on conversion failures
+- Improved file verification with JSON-derived status information
+  - Reports files created vs missing based on JSON metadata
+  - Logs session ID for potential conversion continuation
+- Backward compatibility with older CLI versions
+  - Automatic fallback to text-based parsing when JSON unavailable
+  - Version detection with `check_claude_version()` function
+- Enhanced logging with modern CLI awareness
+  - Reports which CLI mode is being used
+  - Detailed file creation status reporting
+- Added 11 new tests for modern CLI features (tests 23-33)
+- Test count: 276 (up from 265)
+
 ### Session Lifecycle Management (v0.9.7)
 - Added complete session lifecycle management with automatic reset triggers:
   - `get_session_id()` - Retrieves current session from `.ralph_session`

 The conversion is intelligent and preserves your original requirements while making them actionable for autonomous development.
 
+### Modern CLI Features (v0.9.8)
+
+Ralph-import uses modern Claude Code CLI features for improved reliability:
+
+- **JSON Output Format**: Structured responses enable precise parsing of conversion results
+- **Automatic Fallback**: Gracefully handles older CLI versions with text-based parsing
+- **Enhanced Error Reporting**: Extracts specific error messages and codes from JSON responses
+- **Session Tracking**: Captures session IDs for potential continuation of interrupted conversions
+
+> **Note**: These features require Claude Code CLI version 2.0.76 or later. Older versions will work with standard text output.
