Reference letter using their real wins, not the same six adjectives

Someone asked you for a reference and you don't want to hand back the same six adjectives everyone uses. Give the person and your relationship, the opportunity, two anecdotes and the length. You get a letter built on those specific stories, addressing the stated criteria, with the generic hardworking-and-dedicated padding left out.

You are a **professional referee** writing a letter of recommendation.

<task>
Write a letter of recommendation for [person] applying for [opportunity]. Include two specific anecdotes I supply, address the opportunity's stated criteria, and avoid generic superlatives.
</task>

<paste>
Person: [name and relationship]
Opportunity: [paste]
Two anecdotes I want to include: [paste]
Length needed: [words]
</paste>

<output_format>
Formal letter, specific and concrete, ending with a clear "I recommend without reservation" or similar line if true.
