Resume Ats Linkedin Optimizer

Resume + ATS + LinkedIn Optimizer

Turn a person's real experience into the strongest possible resume, CV, and LinkedIn profile — one that survives every major ATS parser, wins the 7-second recruiter skim, and ranks in LinkedIn recruiter search. This skill encodes what university career centers (Harvard, MIT), ex-FAANG recruiters, eye-tracking research, and the actual behavior of production ATS agree on, and resolves the places where popular advice is wrong or outdated.

The prime directive: zero fabrication

Never invent, inflate, or guess a fact. No fabricated employers, titles, dates, degrees, or metrics. This is non-negotiable and overrides every other goal — a resume that lies fails the moment a recruiter or reference check catches it, and it puts the user's career at risk.

What this means in practice:

• Every number, employer, title, and date must come from the user or a document

they gave you. If you don't have it, ask — don't fill it in.

• Metrics the user has but didn't write down are fair game to excavate

(Phase 2). Estimates are allowed only when the user confirms them and they are hedged ("~", "approximately", "roughly"). See assets/metric-proxies.md.

• You may sharpen language freely (weak verb → strong verb, task → outcome,

vague → specific). You may not sharpen facts.

• When you reword something, preserve its truth. "Helped build" does not become

"single-handedly architected."

If the user pushes you to fabricate, refuse and explain the risk, then offer the honest alternative (excavate a real number, reframe, or omit).

Mental model (get this right, everything else follows)

A modern hiring pipeline is two stages, and parsing is the gate before everything:

1. Parse + store. The file is flattened to plain text and mapped into fields

(name, contact, roles, dates, skills). If the parser can't read something, it is invisible to every downstream step, including any AI layer.

1. Search + rank + (increasingly) AI-summarize. Recruiters run keyword

searches over the parsed database; an LLM layer may summarize and score on top. Humans still make the decision.

The load-bearing truth: ATS almost never auto-reject (≈92% of recruiters say theirs don't). The "ATS rejects 75% of resumes" stat is a myth from a defunct 2012 vendor. What feels like bot-rejection is human overload (hundreds to thousands of applicants) plus knockout questions. So optimize for (a) clean parsing and (b) a fast, convincing human skim — not for gaming a rejection algorithm that mostly doesn't exist. Details + myths: references/07-myths-and-truth.md.

The single source of truth: the Master Profile

Do not tailor by rewriting from scratch each time. Maintain a Master Profile — an exhaustive, private store of everything the user has ever done (every role, bullet, metric, skill, project). Every resume and LinkedIn variant is then a selection and reframing of that store, never an invention on top of it. This is what makes tailoring fast, consistent, and truthful.

• If the user has no Master Profile yet, build one first (assets/master-profile-template.md).
• If they do, load it and update it with anything new before tailoring.
• Full workflow and the role "visibility" system: references/05-master-profile.md.

Modes

Detect which the user wants (ask if unclear) and follow the phases below.

| Mode | Trigger | Phases | |---|---|---| | Build | "make/write my resume", from scratch or from raw material | 0 → 6 | | Improve | "fix / make my resume better", no specific job | 0,1,2,3,5,6 | | Tailor | "tailor my resume to this job" + a job description | 0,1,4,2,3,5,6 | | Audit | "check / score my resume", "is this ATS-friendly" | 0,3,4,6 (report only) | | LinkedIn | "optimize my LinkedIn" | 0,1,7 | | Apply/skip | "should I apply to this?" | 0,4 → references/03-keywords-and-tailoring.md gate | | Cover letter | "write a cover letter" | 0,4 → references/08-cover-letters.md |

Workflow

Work through phases in order for the chosen mode. Gate each phase: do not move on until its exit condition is met. Load the linked reference when you reach that phase — don't front-load everything.

Phase 0 — Intake & Master Profile

• Establish the goal: target role/industry, seniority, and whether there's a

specific job description. Determine career stage (new grad / mid / senior / career-changer) — it drives section order and emphasis.

• Gather raw material: existing resume, LinkedIn export, job history, or a

conversation. Load into / create the Master Profile.

• Exit when: you have a Master Profile (even a rough one) and a clear target.

Phase 1 — Metric Excavation & fact-gathering

• The highest-leverage step. Most people undersell themselves. For each

significant role/bullet, ask targeted questions to surface real numbers: scope (team size, budget, users, volume), change (before → after, %), time/speed, money, and quality. Use assets/metric-proxies.md to prompt plausible ranges — but every number must be confirmed by the user.

• Also collect: domain/context (the "secret weapon" — "web apps" →

"fintech card-issuance platform"), tools/tech, and outcomes.

• Exit when: each headline achievement has real, user-confirmed substance.

Phase 2 — Content engineering (bullets, verbs, summary)

• Rewrite every bullet to **Action verb + what you did + quantified impact +

(how/context)** — the XYZ / Google formula ("Accomplished X, measured by Y, by doing Z"). Lead with impact, not task.

• Use strong, plain verbs (led, built, designed, cut, shipped, grew); kill

"responsible for / helped / worked on" and buzzword-inflated verbs. Full guidance, verb bank, and before/after examples: references/02-content-and-bullets.md and assets/action-verbs.md.

• Run the de-slop pass: remove AI-tells and filler (assets/ai-slop-blacklist.md).
• Write the professional summary (if ≥1–2 yrs experience) or objective (new

grad / career-changer).

• Exit when: bullets are outcome-led, quantified where honest, and slop-free.

Phase 3 — Structure & ATS-safe formatting

• Enforce the non-negotiable ATS format: **single column; no tables, text boxes,

columns, headers/footers, graphics, or icons; standard section headings; standard bullets; web-safe font 10–12pt; contact info in the body.**

• Order sections by career stage; reverse-chronological; dates as

Month Year – Month Year + "Present". Full rules: references/01-ats-and-formatting.md.

• Exit when: structure passes the ATS-safe checklist in that reference.

Phase 4 — Keywords & tailoring (Tailor/Audit/Apply modes)

• Analyze the job description: extract and tier keywords (required vs preferred),

find the most-emphasized terms, run a gap analysis vs the Master Profile.

• Mirror the JD's exact hard-skill wording (ATS often don't resolve

synonyms); include acronym + spelled-out pairs ("SEO (Search Engine Optimization)"). Place each key term in ≥2 places (skills + a real bullet). No stuffing, no hidden text — both backfire. Use scripts/resume_tools.py coverage for a labeled keyword-coverage estimate. Details + apply/skip gate: references/03-keywords-and-tailoring.md.

• Exit when: required keywords the user genuinely qualifies for are present

and natural.

Phase 5 — Render

• Prefer the LLM-writes-JSON, code-renders-doc pattern: put content in

assets/resume.schema.json shape, then python scripts/resume_tools.py render --resume resume.json --out resume.pdf (or .docx) produces a clean, single-column, ATS-safe file with selectable text. This keeps layout deterministic and parseable. Text-based PDF is the safe default for submission; keep .docx for portals that request Word.

• File name: Firstname-Lastname-Resume.pdf.
• Exit when: a rendered file exists and its text is selectable/copyable.

Phase 6 — Evaluate

• Run the scoring rubric and the truthfulness invariants (no section

dropped, no employer/date/title that wasn't in the source, identity untouched): python scripts/resume_tools.py validate and see references/06-scoring-and-evaluation.md.

• Do the skim test: in 7 seconds can you find name, current title+company,

and the top achievement? Is the strongest material in the top third?

• Report a keyword-coverage estimate (explicitly labeled an estimate, never

a fake "100/100 ATS score").

• Exit when: invariants pass and the skim test succeeds.

Phase 7 — LinkedIn (LinkedIn mode)

• Port the same keyword spine into LinkedIn, adapting for its algorithm and

human, in-feed reading: headline (220 chars, front-loaded, keyword-rich), About (hook in the first ~300 chars, first-person story, CTA), experience (conversational + media), pinned top-3 skills, All-Star completeness. Per-field limits, formulas, and checklist: references/04-linkedin.md.

• Exit when: every field has a concrete recommendation and the profile hits

All-Star.

Reference & asset map

Load references on demand as you reach the phase that needs them.

• references/01-ats-and-formatting.md — how each ATS parses, what breaks it,

format rules, headings, dates, PDF vs DOCX, file naming, length.

• references/02-content-and-bullets.md — XYZ/CAR formulas, quantification,

summary vs objective, recruiter skim behavior, red-flag handling, tense/voice.

• references/03-keywords-and-tailoring.md — JD analysis, keyword tiering,

coverage scoring, apply/skip gate.

• references/04-linkedin.md — algorithm, per-field limits + formulas, skills,

featured/recommendations/URL/banner/photo, resume↔LinkedIn diffs.

• references/05-master-profile.md — the source-of-truth doc + visibility system.
• references/06-scoring-and-evaluation.md — rubric, truthfulness invariants,

skim test.

• references/07-myths-and-truth.md — myths to stop repeating; what's actually true.
• references/08-cover-letters.md — when to write one, structure, rules, template.
• assets/master-profile-template.md, assets/resume.schema.json,

assets/example-resume.json, assets/action-verbs.md, assets/metric-proxies.md, assets/ai-slop-blacklist.md.

• scripts/resume_tools.py — render (JSON→ATS-safe .docx), validate

(truthfulness invariants), coverage (JD keyword-coverage estimate), deslop (flag AI-tells/filler). python scripts/resume_tools.py --help.

Hard rules (never violate)

1. Zero fabrication. See prime directive.
2. Single column, no tables/graphics/headers-footers. Parsing gate.
3. Standard section headings and reverse-chronological order.
4. Exact-match JD keywords, placed naturally — never stuffed or hidden.
5. Quantify honestly. Estimates only when user-confirmed and hedged.
6. No fake "ATS score." Report a labeled keyword-coverage estimate only.
7. Plain strong verbs over buzzwords. Run the de-slop pass on every draft.
