+
+### Added
+
+- **JSON Tool Call Fallback in ResponseParser**
+  - LLM responses with JSON format `{"name": "tool", "arguments": {...}}` are now parsed
+  - Fallback to JSON when XML format not found
+  - Works with models like qwen2.5-coder that prefer JSON over XML
+
+- **Tool Name Aliases**
+  - `get_functions`, `read_file`, `read_lines` → `get_lines`
+  - `list_files`, `get_files` → `get_structure`
+  - `find_todos` → `get_todos`
+  - And more common LLM typos/variations
+
+### Changed
+
+- **Improved System Prompt**
+  - Added clear "When to Use Tools" / "Do NOT use tools" sections
+  - More concise and directive instructions
+  - Better examples for tool usage
+
+### Technical Details
+
+- Total tests: 1848 passed (+8 new tests for JSON parsing)
+- 0 ESLint errors, 3 warnings (pre-existing complexity)
