⚡ Key issues to review Version Tracking The addition of version tracking directly in the protobuf definition for `StatusRequest` may lead to compatibility issues with clients not supporting this new field. Consider implications on existing clients and whether a fallback or default behavior is needed. Database Error Handling The error handling for database operations in the `SendStatus` method does not differentiate between different types of database errors (e.g., connection issues vs. constraint violations). This could be improved by implementing more granular error handling to respond appropriately based on the error type. Hardcoded Version The agent version is hardcoded in `agent.go`, which could lead to maintenance issues when versioning the agent. Consider a dynamic approach to manage versions, possibly through build-time variables or a configuration file.

✨ Test tool usage guide:

---

The `test` tool generate tests for a selected component, based on the PR code changes. It can be invoked manually by commenting on any PR: ``` /test component_name ``` where 'component_name' is the name of a specific component in the PR. To get a list of the components that changed in the PR, use the [`analyze`](https://pr-agent-docs.codium.ai/tools/analyze/) tool. Language that are currently supported: Python, Java, C++, JavaScript, TypeScript. Configuration options: - `num_tests`: number of tests to generate. Default is 3. - `testing_framework`: the testing framework to use. If not set, for Python it will use `pytest`, for Java it will use `JUnit`, for C++ it will use `Catch2`, and for JavaScript and TypeScript it will use `jest`. - `avoid_mocks`: if set to true, the tool will try to avoid using mocks in the generated tests. Note that even if this option is set to true, the tool might still use mocks if it cannot generate a test without them. Default is true. - `extra_instructions`: Optional extra instructions to the tool. For example: "use the following mock injection scheme: ...". - `file`: in case there are several components with the same name, you can specify the relevant file. - `class_name`: in case there are several components with the same name in the same file, you can specify the relevant class name. See more information about the test tool in the [docs](https://pr-agent-docs.codium.ai/tools/test/).
