2. Highlights the candidate's key strengths with specific examples
3. Mentions any notable achievements or contributions
4. Makes a strong case for why the candidate is recommended
5. Closes with an enthusiastic endorsement and offer to provide further information
6. Is appropriately formal and 3-4 paragraphs long

Return only the letter text, nothing else.
