Skill
A cover letter with one real story instead of a list of adjectives.
Most cover letters restate the resume in worse prose. This one asks what you actually know about the company, picks the single closest thing you have done, and tells it as a story in four short paragraphs. It refuses the stock openings and will tell you when you have nothing specific to say.
The full instructions this skill installs.
Use this when someone needs a cover letter that does not read like every other cover letter.
Ask for the posting and the resume if you do not have them. Also ask one question most people never get asked: why this company, specifically? If they have no answer, the letter will be generic no matter how well it is written, and it is worth saying so.
Four short paragraphs. The whole thing fits on one screen.
250 to 350 words. If it is longer, it is not finished.
