This provides the AI with a deep understanding of the project's composition, dependencies, and configuration. |
| | Dependency Graph Generation | The codebase-scanner.ts service is capable of identifying and mapping out dependencies within the project, represented as FileNode and DependencyEdge within a DependencyGraph. This information is crucial for the AI to accurately describe how different parts of the project interact. |
| Customizable Output | Documentation Template Utilization | Leverages a collection of pre-defined, extensible prompts (README_PROMPT, CONTRIBUTING_PROMPT, LICENSE_PROMPT from src/utils/prompts.ts) to ensure generated documents adhere to best practices and project requirements. Users can configure how the AI interprets and fills these templates. |
| | Dynamic Logo Generation | Includes src/services/logo-generator.ts which provides functionalities to manage and potentially generate or integrate project logos based on specified LogoOptions, ensuring a complete and professional documentation package. Output includes GeneratedLogo data. |
| Developer Experience | Command-Line Interface (CLI) | Provides a straightforward and intuitive command-line interface (src/bin/cli.ts) for easy execution and interaction. Users can initiate documentation generation with simple commands. |
| | Integrated Logging | Incorporates a centralized logging utility (src/utils/logger.ts) to provide clear feedback during the documentation generation process, indicating progress, warnings, and errors directly to the user. |
| Maintainability | Service Layer Architecture | Built upon a robust "Service Layer" architectural pattern, promoting separation of concerns, modularity, and easier maintenance. This design makes the codebase highly scalable and extensible for future enhancements. |

🛠️ Tech Stack

DocSage v2 is built using modern and efficient technologies to ensure high performance, reliability, and maintainability.

| Category | Technology | Purpose |
| :---------------- | :---------- | :------------------------------------------------------------------------------------------------------ |
| Language | TypeScript | Provides strong typing, enhanced tooling, and improved code quality and maintainability for the project. |
| Package Manager | npm | Manages project dependencies, scripts, and package distribution. |
| AI Integration| Gemini | (Implied) Powers the intelligent content generation for documentation. |

🏛️ Architecture

DocSage v2 adopts a clean and modular "Service Layer" architectural pattern, ensuring separation of concerns, reusability, and ease of maintenance. The core logic is encapsulated within various services, orchestrated by a central CLI entry point.

The system flow typically begins with the CLI, which interacts with the file system and codebase scanner to gather project information. This information is then fed into the AI service (Gemini) along with predefined prompts to generate documentation content. Finally, the generated content is written back to the file system.

Component Breakdown:

* src/bin/cli.ts: This is the primary entry point for users interacting with DocSage v2. It parses command-line arguments, orchestrates the workflow, and invokes the appropriate services based on user input. It acts as the "Controller" in the service layer pattern.
* src/services/file-system.ts: Responsible for all file system operations. This includes reading file content (readFileContent), obtaining the project's directory structure (getProjectStructure), and retrieving content from key files (getKeyFilesContent). It abstracts away the low-level I/O details.
* src/services/codebase-scanner.ts: This service is the intelligence behind understanding the project. It uses file-system.ts to read files and directories, constructs a FileNode representation, identifies DependencyEdges, and builds a comprehensive DependencyGraph of the codebase. This analysis forms the basis for AI content generation.
* src/services/gemini.ts: Encapsulates all interactions with the Gemini AI model. This service takes the codebase analysis data and relevant prompts, sends them to the AI, and processes the AI's generated textual content for documentation. It exports GeminiService to manage these AI interactions.
* src/services/logo-generator.ts: A utility service dedicated to managing and potentially generating or modifying project logos. It defines LogoOptions and returns GeneratedLogo data, supporting the visual elements of documentation.
* src/utils/prompts.ts: This module centralizes the various prompts (README_PROMPT, CONTRIBUTING_PROMPT, LICENSE_PROMPT) used to guide the AI's generation process. These prompts provide structure and context for the AI, ensuring the output aligns with typical documentation standards.
* src/utils/logger.ts: Provides a standardized logging mechanism (logger) across the application, making it easier to track execution flow, debug issues, and provide informative output to the user.

Service Layer Pattern:
The "Service Layer" pattern is evident throughout the architecture. Each service (file-system, codebase-scanner, gemini, logo-generator) is dedicated to a specific business capability or domain logic. These services are independent and can be composed by higher-level orchestrators (like cli.ts). This design promotes a clear separation of concerns: cli.ts handles user interaction, services handle specific operations, and utils provide shared functionalities. This modularity makes the system robust, testable, and extensible.
