SDLC Copilot is an AI-powered agent designed to streamline SDLC phases: from requirement gathering to deployment. It processes user inputs or imported project specifications, then leverages natural language processing to break down requirements into actionable tasks. It generates UML class and sequence diagrams, proposes architecture plans, scaffolds code modules in multiple languages, drafts API documentation, and auto-generates unit and integration test cases. It integrates with Git-based workflows, issue trackers, and CI/CD pipelines to continuously analyze changes, suggest improvements, and enforce coding standards. Developers can interact through a chat UI or CLI to refine outputs, ask for refactoring suggestions, or request performance optimization tips, making SDLC Copilot a central hub for project management and code quality assurance.
