The Pyflakes architecture is a streamlined static analysis pipeline, designed for efficiency and modularity. The CLI & File System Orchestrator (pyflakes/api.py) serves as the user-facing interface, managing input and output, and coordinating the analysis process. It delegates the task of reading source files to the Source Code Reader (pyflakes/api.py). The heart of the system is the AST Generation & Analysis Engine (pyflakes/api.py, pyflakes/checker.py), which transforms source code into an Abstract Syntax Tree and applies various checks to identify code quality issues. All findings are then channeled to the Issue Reporting & Messaging component (pyflakes/reporter.py, pyflakes/messages.py), which standardizes and presents the results. This clear, sequential flow makes Pyflakes highly effective as a static analysis tool, with distinct components that facilitate easy understanding and visual representation in a flow diagram.
CLI & File System Orchestrator [Expand]
The entry point for Pyflakes, handling command-line arguments, file system traversal, and orchestrating the overall analysis workflow. It manages user interaction and output display.

AST Generation & Analysis Engine [Expand]
The core static analysis component. It parses raw source code into an Abstract Syntax Tree (AST) and traverses it to identify potential code issues using a visitor pattern.
