Sub-issues

Description

In software development, type definitions play a crucial role in ensuring the consistency and accuracy of code. However, when working with multiple providers, maintaining a unified type system can be challenging. To address this issue, we propose creating a central types.py module with standardized TypedDict definitions that can be used across all providers. This approach will not only improve type safety but also enhance the overall maintainability and scalability of our codebase.

Acceptance Criteria

To ensure the successful implementation of unified type definitions, we have established the following acceptance criteria:

Create a Central Types Module

Create a types.py module in the src/lluminary/models/ directory.
Define common TypedDict structures for various use cases, including:
- Message formats: Text, image, and tool content formats.
- API request/response structures: Standardized structures for API requests and responses.
- Usage statistics: Definitions for tracking usage statistics.
- Error details: Structures for representing error details.

Update Providers to Use Shared Types

Update all provider files in src/lluminary/models/providers/* to use the shared types defined in the central types.py module.

Add Comprehensive Type Checking Tests

Create comprehensive type checking tests to ensure the correctness and consistency of the shared types.

Update Documentation

Update the documentation to include an explanation of the type system and how it is used throughout the codebase.

Related Components

The following components are related to this issue:

src/lluminary/models/types.py (new): The central types.py module containing standardized TypedDict definitions.
src/lluminary/models/providers/* (all provider files): Updated provider files using the shared types.
tests/unit/test_types.py (new): Comprehensive type checking tests for the shared types.

Testing Requirements

To ensure the successful implementation of unified type definitions, we have established the following testing requirements:

Verify type compatibility with mypy --strict: Run mypy with the --strict flag to verify the type compatibility of the shared types.
Ensure no regression in existing functionality: Verify that the implementation of unified type definitions does not introduce any regressions in existing functionality.
Test type inference in IDE environments: Test the type inference capabilities of IDEs to ensure that the shared types are correctly inferred.

Priority

The priority of this issue is High, as it addresses a critical aspect of code maintainability and scalability.

Estimated Complexity

The estimated complexity of this issue is Medium-High, as it involves creating a central types.py module, updating multiple provider files, and adding comprehensive type checking tests.

Q&A

Q: What is the purpose of implementing unified type definitions across providers?

A: The primary goal of implementing unified type definitions across providers is to ensure consistency and accuracy in our codebase. By defining a central types.py module with standardized TypedDict definitions, we can improve type safety, enhance maintainability, and ensure scalability.

Q: Why is it necessary to create a central types module?

A: Creating a central types.py module allows us to define a single source of truth for our type definitions. This ensures that all providers use the same types, reducing the risk of inconsistencies and errors.

Q: What types of definitions should be included in the central types module?

A: The central types.py module should include definitions for various use cases, such as:

Message formats: Text, image, and tool content formats.
API request/response structures: Standardized structures for API requests and responses.
Usage statistics: Definitions for tracking usage statistics.
Error details: Structures for representing error details.

Q: How will the providers be updated to use the shared types?

A: The providers will be updated to use the shared types by modifying their respective files in the src/lluminary/models/providers/* directory. This will involve replacing existing type definitions with the standardized types defined in the central types.py module.

Q: What testing requirements are necessary to ensure the successful implementation of unified type definitions?

A: To ensure the successful implementation of unified type definitions, the following testing requirements must be met:

Verify type compatibility with mypy --strict: Run mypy with the --strict flag to verify the type compatibility of the shared types.
Ensure no regression in existing functionality: Verify that the implementation of unified type definitions does not introduce any regressions in existing functionality.
Test type inference in IDE environments: Test the type inference capabilities of IDEs to ensure that the shared types are correctly inferred.

Q: What is the estimated complexity of implementing unified type definitions across providers?

A: The estimated complexity of implementing unified type definitions across providers is Medium-High, as it involves creating a central types.py module, updating multiple provider files, and adding comprehensive type checking tests.

Q: Why is this feature essential for the long-term success of our project?

A: This feature is essential for the long-term success of our project because it addresses a critical aspect of code maintainability and scalability. By implementing unified type definitions across providers, we can ensure consistency, accuracy, and maintainability of our codebase.

Q: What are the benefits of implementing unified type definitions across providers?

A: The benefits of implementing unified type definitions across providers include:

Improved type safety: By defining a central types.py module, we can ensure that all providers use the same types, reducing the risk of inconsistencies and errors.
Enhanced maintainability: With a single source of truth for our type definitions, we can easily update and maintain our codebase.
Increased scalability: By using standardized types, we can ensure that our codebase is scalable and can handle increased traffic and complexity.
