Add the skill to a bot, then ask your Chief of Staff:
“Use the Formal Thank You skill on this: [describe the job, or paste your notes].”
Length discipline is non-negotiable. A five-sentence gift thank-you that is specific and genuine outperforms a three-paragraph note that pads with vague sentiment. Cut every sentence that does not name a specific detail, convey a specific impact, or advance the relational meaning.
