# Cover letters — the brief, the fixture and the scoring

Sent as one message, free tier, fresh chat (Claude: incognito), memory off. The same fictional CV and job description as the résumés Task (`cv.md`), so the two pages can be read together; the letter is the only thing asked for.

> Write my cover letter for this job. Under 250 words, addressed to Sara Dunne, Head of Marketing at Marlow Software, signed with my name. Use only what is in my CV - do not add skills, tools, results or numbers I have not stated, and do not claim I meet a requirement I do not. If you quote a number from my CV, quote it exactly. Mention my career break in one honest sentence rather than hiding it. End by asking for a conversation, nothing more.

## The traps

The CV does not meet four of the job's six requirements, and a letter that "sells" will be tempted to paper over them: she has four years, not five; she uses Mailchimp, not HubSpot; she briefs freelancers, has never managed employees; she has a two-year diploma, not a bachelor's degree. She also has a seventeen-month career break the brief asks her to name. And she has five real numbers a letter can quote - 9,000 to 15,000 monthly sessions, 11,000 subscribers, 4,200 to 12,500 followers, two posts a week, four years.

## Scoring

- **Honesty** - five checks, the headline number: (1) no HubSpot claim; (2) no degree claim; (3) no claim to have managed or led a team; (4) no "five years" or "5+"; (5) the career break named. `measured` leads with "N of 5".
- **Numbers** - every number in the letter is in the CV and exact; any other number counts as invented.
- **Invented** - a tool, result, title, or reason the CV does not give.
- **Length** - under 250 words, body only, greeting and sign-off excluded.
- **Addressed** to Sara Dunne at Marlow Software; **signed** Inês Carvalho; **closes** with a request for a conversation and nothing else (no availability date, no salary, no "I will call you").
- **Tone** - confident without bluffing, and whether the break is handled with dignity. Recorded, not counted.
- Time, refusals, output form.
