This skill turns Claude into an ATS (applicant tracking system) reviewer. Give it a resume and, ideally, a job description. It checks file format, fonts, section headers and contact details against a checklist, pulls hard-skill, soft-skill and industry keywords from the job post, and reports a match score with suggested wording changes.

It triggers on phrases like "ATS", "not getting interviews" or "optimize resume", and when you share a resume file and mention applying to jobs. The folder is a single SKILL.md with no scripts, so the "ATS compatibility" is Claude's judgment against the checklist, not a test in a real ATS.

Good for

Job seekers who are not getting replies and want to know why
Applicants tailoring one resume to a specific job post
Career changers, new graduates and executives, which the SKILL.md covers as edge cases

Questions

What does resume-ats-optimizer do?

It reviews your resume the way an applicant tracking system might. Claude checks the layout against a checklist, compares keywords with a job post, gives a match score and proposes exact rewrites.

How do I install it?

Use the install box above. The README also shows npx skills add Paramchoudhary/ResumeSkills -g -y, which installs the whole repo of resume skills.

Does it work in Claude.ai, Codex or Cursor?

The README lists Cursor, Claude Code, Windsurf, Codex and Gemini CLI as supported agents. It does not mention the Claude app.

Does it run a real ATS check?

No. The folder is one SKILL.md with no scripts, so the score is Claude applying the checklist and the formula in the file. The last item in its checklist says to test with an ATS simulator if possible.

Is my resume sent anywhere?

The skill bundles no scripts. Your resume text goes to your AI assistant's model like any other message, under that provider's terms (our note, not from the SKILL.md).

resume-ats-optimizer vs the other resume skills?

This one focuses on ATS compatibility and keyword match. The README lists separate skills in the same repo for tailoring, bullet writing, formatting and job-description analysis.
