A self-serve toolkit for checking your own resume for layout and keyword problems. Five plain-text (markdown) files. No account, no subscription, and nobody handles your personal data. Why these two checks: a 2026 report from the resume tool ResumeAdapter, covering 10,000 scans run through its own 0-100 scoring tool, states "Out of 10,000 resume scans: Passing rate: 28.6%. Rejection rate: 71.4%." (that tool's passing line was 75 out of 100). It is one vendor's tool, not a measure of any employer's system. Source: resumeadapter.com/blog/2026-ats-rejection-report-10000-resume-scans What you get (5 files): toolkit-readme.md - A guide to the other four files: what each does, a suggested order to use them, and what the toolkit can and cannot do. toolkit-checklist.md - My own 57-point self-scoring rubric (sections A to F with fill-in boxes: keyword coverage 21, job title alignment 6, formatting 8, quantified bullets 8, structure 8, recency/depth 6), a scoring scale, a priority fix order, and a 15-minute tailoring method for repeat applications. toolkit-before-after.md - A worked, annotated before/after example for a fictional person, Marcus Okafor (invented, not a real client). I scored his resume 20/57 before and 55/57 after using the same rubric. Those are my own scores, not scores from any ATS or third-party tool. Includes a LinkedIn headline and About rewrite. toolkit-templates.md - A single-column resume template and LinkedIn headline, About and skills templates with fill-in instructions, plus a tailoring checklist for each application. toolkit-keyword-guide.md - A 5-step process for extracting keywords from a job posting, a table of common synonym mismatches, example keyword lists by role family, and an honesty rule: only add keywords for skills you actually have. The rubric is my own: the point values are my judgment, not a vendor's formula and not a third-party ATS score. It does not simulate any employer's system. What this is not: A done-for-you service. A guarantee of any ATS result or interview. Time estimates inside the files are my own rough guesses.
