prompt-improver

This skill enriches vague prompts with targeted research and clarification before execution. Should be used when a prompt is determined to be vague and requires systematic research, question generation, and execution guidance. TRIGGER WHEN: the UserPromptSubmit hook flags a prompt as vague and the agent needs to research, generate clarifying questions, and wrap the prompt in an evaluation block. DO NOT TRIGGER WHEN: the prompt is already specific, or the user is invoking a slash command (the hook bypasses those via the /, #, @, ! prefixes).
