+- State what is missing and, briefly, why it affects the result. Prefer concrete answer formats or examples so the user can reply once.
+- Do not leave blank fields, silently omit required sections, invent values, copy demo/sample values, or choose a default for a required or confirm-first field.
+- Do not run downstream analysis, create an artifact, or give business verdicts that depend on the missing information until the user answers.
+- Optional fields may remain absent only when the Skill/template explicitly marks them optional and their absence does not make the result misleading.
+- A fallback such as “trend only”, “unknown”, or a placeholder does not replace clarification when the Skill/template identifies the information as required or confirm-first.
