Including expectations about format and level of detail is a core prompt engineering principle for Copilot Chat; by specifying how the output should be structured (e.g., bullet points, paragraph length, depth of summary), the user ensures Copilot has enough context to tailor its response appropriately. This directly addresses completeness of responses when summarizing emails and documents, as Copilot needs explicit guidance on the desired output format to avoid vague or overly verbose results.

Comparing different pieces of text to identify similarities is a text analysis task, not a prompt element needed to ensure complete summarization responses from Copilot Chat.

Classification of text based on content is a categorization task and does not serve as a prompt element that helps Copilot Chat produce complete summarization responses.

Generation of new text describes a general AI capability, not a specific prompt element that the user should include to ensure Copilot Chat provides complete and well-structured summaries.
