From the repository
Follow the repository README to install the server and add its MCP configuration to your client.
improve_prompt
Rewrite a rough prompt into a sharper, ready-to-use prompt structured as Role, Task, Context, Format (RTCF). Returns the improved prompt plus its four parts. Use this before answering when the user's request is vague, or when the user asks to improve a prompt.
build_prompt
Compose a ready-to-use prompt from explicit Role, Task, Context, and Format parts. Use when the user already knows the pieces and wants them woven into one clean prompt.
