The best Claude skills for your job search (all free)

Ask an AI to "make my resume sound better" and you can get back confident bullets full of numbers you never gave it. That's a real problem in a job search: anything on your resume or in your cover letter can come up in an interview, and you need to be able to back it up.

The seven skills in the Skillshelf Job search collection share one rule: they never invent experience, numbers or results. Where a detail is missing, they leave a [placeholder] and ask you for it. They're all free, and each skill's page shows a real example of it at work before you download it.

Your resume

Resume Bullets

Rewrites resume and LinkedIn bullets so each one starts with a strong verb, says what you did and shows the result. It drops filler like "responsible for" and "duties included", keeps each bullet to a line or two, and doesn't repeat the same opening verb within one role. It also won't upgrade your role: "helped with" doesn't become "led" unless you confirm it.

In its example, "helped with the food drive" became "Supported a campus food drive that collected [N] lbs of food for [organization] by [your main task, e.g. sorting donations]." Then it asked what the main job was and roughly how much food was collected, so the final bullet has real numbers in it.

Applications

Cover Letter

Writes a short, tailored cover letter from your experience and the job posting, matching what you've really done to what the employer asks for. It stays under 300 words, uses the posting's own words for skills, and skips "I am writing to apply for" and clichés like "team player" and "passionate". It won't invent your reasons for wanting the job: if you haven't said why, it leaves a placeholder and asks.

Try: "can u write me a cover letter for this job", then paste the posting and a few lines about yourself.

Proofreader

Fixes spelling, grammar and punctuation and explains each fix in one line. It doesn't rewrite for style or change what you're saying; sentences that are correct but awkward are listed under "Worth a look" for you to decide. Run it on every application, resume and cover letter before you send it.

Emails with recruiters

Email Reply

Drafts a reply from your notes on what you want to say, making sure every question in the original gets an answer, and matching the sender's tone. It never commits you to anything you didn't say: dates, times, salary numbers and attachments become placeholders.

In its example, a recruiter asked for a call time, salary expectations and a transcript. The draft answered all three, politely held off on a number and asked for their range instead, and reminded the sender to actually attach the transcript before sending.

Email Tone

Rewrites a message you've already written to be firmer, friendlier, more formal, shorter or calmer, keeping every fact, date and request. Useful for a follow-up after you haven't heard back, or a polite "no" to an offer. It never adds deadlines or promises you didn't write.

Interviews

Interview Prep

Turns your real experiences into STAR answers (Situation, Task, Action, Result) for behavioral questions like "Tell me about a time you dealt with a difficult customer." It predicts likely questions from the job posting and can run a mock interview with feedback. It makes sure the Action says "I", not "we", never blames past bosses or coworkers, and asks about details instead of making them up.

Try: "interview for a retail sales associate job next week. how do i answer 'tell me about a time you dealt with a difficult customer'", plus what actually happened. It also lists the follow-up questions you're likely to get.

Announcing the offer

LinkedIn Post

Writes a LinkedIn post about your new job or internship, graduation or project, with a specific opening line, short paragraphs, thanks to the people you name and at most three hashtags. It skips "thrilled to announce" and "humbled", aims for 80–200 words, and won't name an employer, school or person you haven't named, since some announcements need permission first.
