Check this before you send it: you've made at least three mistakes

You're about to send a cover letter you secretly suspect is weak. This puts it in front of a blunt hiring manager who has read thousands: the worst sentence quoted back, the claim no recruiter will swallow, the thing strong candidates always include and you left out, then a fixed version. Better you wince now than them.

Read my cover letter below and act as a brutally honest hiring manager who has seen thousands of these.

{COVER_LETTER}

The role is {ROLE} at {COMPANY}.

Give me:
1. The single weakest sentence: quote it exactly and explain why it hurts
2. Any claim I make that a recruiter will not believe without more evidence
3. One thing that is missing that a strong candidate for this role would typically include
4. A revised version of just the opening and closing paragraphs

Do not tell me what I did well unless I ask.
