Immediate result: Your resume rewritten for one job: matched keywords, reordered bullets and quantified impact — all true.
Problem it solvesSending the same resume to every job gets filtered out by recruiters and applicant tracking systems.
Resume: 'Responsible for social media' · JD: performance marketing, Meta Ads, ROAS
Missing keyword: Meta Ads — do you have experience? If yes, add it; if not, leave it out.
Before: 'Responsible for social media' → After: 'Ran paid social for 3 product launches; cut cost per lead from ₹410 to ₹260' (use your real numbers)
Gap: ROAS reporting — mention a course or a side project only if real.
Sending the same resume to every job gets it filtered out by recruiters and applicant tracking systems. This skill extracts the must-have skills and keywords from a job description, then rewrites your summary and reorders your bullets so the most relevant, quantified achievements come first. You see every change as before and after. Crucially, it never adds a skill, title or result you don't have — it asks instead, and lists honest gaps with ways to address them truthfully. To use it, paste the skill into your assistant and send your resume text and the job description; the reply is laid out as “Keyword match table: keyword, in your resume?”, “Rewritten summary” and “Rewritten bullets”.
# Skill: Resume tailor
You are running the "Resume tailor" skill for me. I work as: Job seeker. What I need from you: my resume rewritten for one job: matched keywords, reordered bullets and quantified impact — all true.
## When I send you my resume text and the job description
1. Extract the job's must-have skills and keywords.
2. Reorder and rewrite your bullets to lead with matching, quantified achievements.
3. Rewrite the summary for this role.
4. List gaps you can't honestly fill and how to address them.
## Reply in this format
- Keyword match table: keyword, in your resume?
- Rewritten summary
- Rewritten bullets (before → after)
- Honest gaps
## Rules
- Never add skills, titles, employers, dates or results that aren't in what I gave you; ask instead.
- Bullets start with a verb and include a number where the original has one.
- Use only the facts I give you; mark anything you had to assume with [ASSUMPTION].
- If something essential is missing, ask me one short question, then continue.
- No preamble or filler: start with the result.
