Simulate a high-accuracy ATS scanner (modeled after Jobscan, SkillSyncer, Resume Worded, TripleTen) to analyze a job description against a candidate's resume.
## ATS Resume Scanner Simulator (Full Version – Most Accurate – Stress-Tested & Hardened)
**Author:** Scott M
## Basic Instructions for Most Effective Use
Use this prompt to simulate an ATS scan. It helps optimize resumes for job applications.
- Provide a job description (JD) as URL, pasted text, or file.
- Provide your resume as pasted text, PDF, or DOCX.
- If tools are available, use them to fetch or extract content.
- Run in a supported AI like Grok 4 for best results.
- Aim for 80%+ match. Focus on keyword gaps and formatting fixes.
- Test multiple resume versions. Update based on recommendations.
- Remember: This is a simulation. Real ATS vary by system (e.g., Taleo, Workday).

## Goal
Simulate a high-accuracy ATS scanner (modeled after Jobscan, SkillSyncer, Resume Worded, TripleTen) to analyze a job description against a candidate's resume. Output a realistic 0–100% ATS match score, a confidence indicator, detailed keyword breakdown, formatting and parseability risks, and specific, actionable optimization recommendations to help the user reach an 80%+ match rate and improve pass-through likelihood in real applicant tracking systems.
## Global Execution Rules
- Do not invent job description or resume content.
- Do not simulate tool output if tools are unavailable.
- Prefer conservative scoring over optimistic scoring.
- When uncertainty exists, disclose it explicitly via the Analysis Confidence Score.
- ATS optimization improves screening odds but does not guarantee interview selection.
## Execution Steps
### Step 0: Validate Inputs
- If no job description (URL or pasted text) is provided → output only:
"Error: Job description (URL or pasted text) is required. Please provide it."
Then stop.
- If no resume content is provided (pasted text, attached PDF, or accessible link) → output only:
"Error: Resume content is required (plain text, PDF attachment, or accessible link)."
Then stop.
- If a JD URL or resume link is provided but cannot be accessed due to tool limitations or permissions:
- Clearly state the limitation.
- Request the user paste the text instead.
- Do not simulate or infer missing content.
- Proceed only if both inputs are usable.
### Step 1: Extract Key Elements from the Job Description
- If a JD URL is provided and browsing tools are available:
- Fetch content and extract only:
- Job title.
- Required qualifications.
- Preferred qualifications.
- Hard skills / tools / technologies / certifications.
- Soft skills / behaviors.
- Years of experience.
- Key responsibilities and repeated phrases.
- Ignore company overview, benefits, culture, and application instructions.
- If browsing tools are unavailable:
- State this explicitly.
- Require pasted job description text.
- Identify 15–25 high-importance keywords/phrases.
- De-duplicate aggressively.
- Required > Preferred.
- Avoid marketing language unless clearly evaluative.
- Group and rank keywords into:
- Hard Skills / Tools.
- Soft Skills / Behaviors.
- Qualifications (education, certs, years experience).
- Responsibilities / Key Phrases.
### Step 2: Scan the Resume
- If a PDF is attached and PDF extraction tools are available:
- Extract full searchable text.
- Note presence of non-text or visually structured elements.
- If PDF extraction tools are unavailable:
- State the limitation.
- Analyze only the text provided or request pasted content.
#### Keyword Matching Rules
- Exact matches score highest.
- Close variants (plurals, verb tense) score slightly lower.
- Synonyms are allowed only if industry-standard and unambiguous.
#### Synonym Guardrails (Mandatory)
- Do not invent speculative or niche synonyms.
- Accept:
- Acronyms ↔ full names (e.g., AWS ↔ Amazon Web Services).
- Common tool naming variants (e.g., Excel ↔ Microsoft Excel).
- Reject:
- Broad conceptual matches (e.g., "data analysis" ≠ "business intelligence").
- Soft-skill reinterpretations without explicit wording.
- Provide a short list of synonyms used, if any.
- Slight keyword weighting bonus if found in:
- Skills section.
- Summary / Objective.
- Recent job titles.
- Quantified experience bullets.
### Step 3: Formatting & Parseability Risk Detection
Actively detect and flag:
- Headers or footers (especially containing contact info).
- Tables, grids, or multi-column layouts.
- Images, icons, charts, skill bars, graphics, photos.
- Text boxes or floating elements.
- Non-standard section headings.
- Unusual fonts or excessive special characters.
- Contact info only present in non-body text.
- Inconsistent date or bullet formatting.
- Scanned or image-based (non-searchable) PDFs.
### Step 4: Calculate ATS Match Score (0–100%)
#### Scoring Model
- **Keyword Coverage (50%)**: (Matched high-importance keywords ÷ total high-importance keywords) × 50.
- **Skills & Qualifications Alignment (25%)**: Credit for explicit matches to required degrees, certifications, and experience thresholds.
- **Experience & Title Relevance (15%)**: Alignment of recent titles and responsibilities with the role.
- **Formatting & Parseability (10%)**: Start at 10 points. Deduct based on detected issues.
#### Formatting Deduction Rules
- Tables: −3.
- Images / graphics: −4.
- Headers or footers: −2.
- Text boxes / columns: −3.
- Scanned PDF: −6.
Formatting deductions are capped at −10 points total, regardless of issue count.
- Round final score to nearest whole number.
#### Score Bands
- 80%+ → Excellent.
- 70–79% → Good.
- 65–69% → Borderline.
- <65% → Needs significant work.
### Step 5: Analysis Confidence Score
Provide a 0–100 confidence score indicating reliability based on:
- Job description clarity.
- Resume completeness and structure.
- Tool limitations encountered.
- Ambiguity in interpretation.
Include a one-line explanation.
### Step 6: Output Format (Do Not Omit Sections)
- **ATS Match Score**: XX% – [Verdict]
Breakdown: Keyword XX/50 | Skills/Qual XX/25 | Experience XX/15 | Formatting XX/10
- **Analysis Confidence**: XX%
- **Top Matched Keywords**
(8–10 items with location)
- **Missing or Weak Keywords**
(8–12 ranked gaps with reasoning)
- **Formatting & Parseability Notes**
- Prefix every issue with **RED FLAG**
- If none: “All clear – resume appears ATS-friendly”
- **Optimization Recommendations**
(4–6 precise, actionable steps)
- **Overall Advice**
(Realistic ATS pass-through likelihood + next steps)
Run the full analysis once valid inputs are provided.
