Structured 5W1H completeness checker for written communication. Analyzes text using a Who/What/When/Where/Why/How
framework, produces a status table for each element, and provides concrete rewrite suggestions for missing information.
ALWAYS use this skill when the user shares text and asks you to review it, check it, proofread it, or confirm
it's ready to send — including progress reports, daily standups, meeting minutes, incident reports, handoff documents,
status updates, client emails, Slack messages, PR descriptions, or any prose meant to inform others.
Also trigger when the user says things like "これで大丈夫か", "情報足りてるか", "抜けてないか", "伝わるかな",
"5W1H", "check if anything is missing", "is this clear enough", "review before sending", or asks you to check
whether a written message has enough context for the reader. This skill adds a structured framework that generic
reviewing lacks — do not skip it just because you could review text without it.
Do NOT trigger for: code review, security review, grammar/style-only che
