# Gemma 4 Developer Agent (`gemma4-dev-agent`)
An autonomous software engineering agent built for the **Google Gemma 4 Developer Agent Competition**. This agent features custom query routing, static AST parsing, multi-file dependency refactoring, and automated test-driven healing powered by `pytest`.
🔗 **GitHub Repository:** [EzioDEVio/gemma4-dev-agent](https://github.com/EzioDEVio/gemma4-dev-agent)

## 🚀 Key Features
* **Intelligent Query Routing:** Context-aware classification mapping user requests to specific developer workflows.
* **Static AST Parsing:** Inspects imports, classes, and function definitions using Python's native `ast` module.
* **Multi-File Dependency Tracking:** Manages cross-file code references and updates dependencies automatically across modules.
* **Automated Pytest Healing (`Test-Driven Repair`):** Detects failing test assertions, patches the underlying logic, and re-runs test suites until all checks pass successfully.
* **Comprehensive Toolset:** Includes robust execution wrappers for bash commands, file reading/writing, AST analysis, and test coverage measurement (`pytest-cov`).

## 📊 Benchmark Results
The agent has been rigorously tested against an advanced evaluation suite covering core software engineering tasks:
| Task ID | Description | Status |
| :--- | :--- | :--- |
| `task_01_refactor` | Code refactoring & function signature updates | **PASSED** |
| `task_02_syntax_fix` | Automatic syntax error detection & fixing | **PASSED** |
| `task_03_multi_file_dependency` | Cross-file function renaming & dependency tracking | **PASSED** |
| `task_04_pytest_healing` | Test-driven error patching & test suite validation | **PASSED** |
* **Overall Score:** **4/4 (100.0%)**

## 🛠️ Supported Tools
1. `execute_bash` - Executes arbitrary bash shell commands on the host system.
2. `file_read` - Safely reads file contents with error handling.
3. `file_write` - Creates or overwrites files and directories.
4. `repo_ast_parser` - Analyzes Python syntax trees for structural overview.
5. `run_pytest` - Executes test suites with optional code coverage flags.
