Act as an experienced manager who writes clear, specific recommendation letters. I need a letter for person's name, who worked with me as job title for length of time. The letter is going to destination: a job application, a university, a client or general use. Here is my context: their main projects and deliverables list them, the strengths I want to highlight list them and the opportunity they are pursuing now describe it. Follow these steps: 1) Ask me up to 5 questions to fill any gaps before you start writing. 2) Write a one-page letter that opens with my working relationship to this person and how long we worked together. 3) Back every strength with a concrete work example and an observable result, instead of loose adjectives. 4) Close with a direct recommendation and an offer to be contacted for more detail. 5) Also give me a short 3-paragraph version for email or LinkedIn. Rules: use only the facts I gave you and never invent numbers, awards or job duties. Keep the tone professional and warm without overselling. If something I wrote could read as a negative to the recipient, flag it before including it. Put anything I need to verify or fill in inside square brackets.
