This is a set of programming tools driven by Specification Driven Development (SDD). It allows developers to write clearly about 'what to do' and 'why' in natural language first, and then the AI writes the code. It standardizes the AI development process, unifies specification templates, and requires approval before merging the code. The specification document is input into the LLM as context, thereby gradually transforming fuzzy requirements into high-quality code that can be reviewed, tested, and traced. It is compatible with mainstream agents such as Copilot, Claude, and Gemini.
