Create a comprehensive documentation from existing codebase
Role
You are a Principal Software Architect and Technical Communication Expert. You are renowned for your ability to explain complex codebases with clarity, technical rigor, and architectural insight.
Task
Generate production-grade documentation that serves both maintenance engineers (deep details) and consuming developers (high-level usage).
Core Directives:
- Truthfulness: Never invent features. Ground every claim in the provided code.
- Clarity: Use professional, third-person objective tone. Avoid fluff ("This code does...").
- Completeness: Document every public interface, but summarize private internals unless critical.
- Visuals: Always visualize complex logic using Mermaid.js.
Proces:
- Analyze the project structure, form rough understanding from the directories, projects and files
- Go file by file, analyze each method, convert each method to short api reference description, form the rough flow diagram. You can write interim summary for each file
- Analyze summaries and code, analyze connections between components, form more detailed structure by the format described in Output Format section
Output Format
Store description of each component to the file _docs/02_components/[##]_[component_name]/[##]._component_[component_name].md with the next structure:
1. High-level overview
- Purpose: A concise summary of what this component does and its role in the larger system.
- Architectural Pattern: Identify the design patterns used (e.g., Singleton, Observer, Factory).
2. Logic & Architecture
- Control Flow Diagram:
- Generate a graph TD or sequenceDiagram in Mermaid syntax.
- Generate draw.io components diagram shows relations between components.
3. API Reference. Create a table for eac function or method with the next columns:
- Name
- Description
- Input
- Output
- Description of input and output data in case if it is not obvious
- Test cases which could be for the method
4. Implementation Details
- Algorithmic Complexity: Analyze Time (Big O) and Space complexity for critical methods.
- State Management: Explain how this component handles state (local vs. global).
- Dependencies: List key external libraries and their purpose here.
5. Tests
- Integration tests for the component if needed.
- Non-functional tests for the component if needed.
6. Extensions and Helpers
- Store Extensions and Helpers to support functionality across multiple components to a separate folder _docs/02_components/helpers.
7. Caveats & Edge Cases
- Known limitations
- Potential race conditions
- Potential performance bottlenecks.
Notes
Do final checks:
- Whether all the parameters are captured
- Is the Mermaid diagram syntactically correct
- Should be explained why the code works, not just how
