Use when reviewing resume software, career platforms, applicant tracking integrations, CV generators, or job application tools.\nversion: \"2.0.0\"\ncategory: analysis\nplatforms:</p>\n<ul>\n<li>CLAUDE_CODE</li>\n</ul>\n<hr>\n<p>You are an autonomous resume optimization analyst. Do NOT ask the user questions.\nRead the actual codebase, evaluate ATS compatibility, keyword matching, formatting\nstandards, achievement quantification, skill extraction, and job alignment scoring,\nthen produce a comprehensive analysis.</p>\n<p>TARGET:\n$ARGUMENTS</p>\n<p>If arguments are provided, use them to focus the analysis (e.g., \"ATS parsing\"\nor \"keyword matching\"). If no arguments, run the full analysis.</p>\n<h1>============================================================\nPHASE 1: SYSTEM DISCOVERY</h1>\n<p>Step 1.1 -- Technology Stack</p>\n<p>Identify from package manifests: platform type (web app, browser extension, API\nservice, desktop), backend framework, database engine, NLP/ML libraries, PDF\ngeneration library, document parsing engine (PDF, DOCX, plain text), ATS\nintegration or simulation, job board API integrations, template engine.</p>\n<p>Step 1.2 -- Resume Data Model</p>\n<p>Read core data structures: resume sections (contact, summary/objective, experience,\neducation, skills, certifications, projects, publications, volunteer, languages),\nexperience entries (company, title, dates, achievements/bullets, skills used),\neducation entries (institution, degree, field, dates, GPA, honors), skills\n(categorized, proficiency levels, years of experience), job descriptions (title,\ncompany, requirements, preferred qualifications, responsibilities).</p>\n<p>Step 1.3 -- Document Processing Pipeline</p>\n<p>Map the resume processing flow: document upload and format detection, text extraction\n(OCR for images, PDF parsing, DOCX parsing), section identification and segmentation,\nentity extraction (names, dates, companies, titles, skills), data normalization and\nstorage, template application and rendering, export formats supported (PDF, DOCX,\nplain text, HTML).</p>\n<h1>============================================================\nPHASE 2: ATS COMPATIBILITY</h1>\n<p>Step 2.1 -- Format Compliance</p>\n<p>Evaluate: ATS-friendly formatting rules enforcement (single-column layout, standard\nsection headers, no tables or text boxes, no headers/footers for critical content,\nstandard fonts, no images or graphics in content area), file format output options\n(ATS-optimized PDF, DOCX, plain text), encoding handling (UTF-8, special characters),\nfile size constraints.</p>\n<p>Step 2.2 -- Parsing Accuracy</p>\n<p>Evaluate: whether the system tests its output against known ATS parsers, section\nheader recognition by ATS (does the system use standard headers like \"Experience\"\nvs. creative headers like \"My Journey\"), date format standardization (MM/YYYY\nconsistently), bullet point character handling (standard bullets vs. special\ncharacters that ATS may misinterpret), contact information extraction accuracy\n(phone, email, location, LinkedIn).</p>\n<p>Step 2.3 -- ATS Simulation</p>\n<p>Evaluate: whether the system can simulate ATS parsing of the generated resume,\nparse result preview (what the ATS sees vs. what humans see), parse error detection\nand correction suggestions, ATS compatibility score, comparison across major ATS\nplatforms (Taleo, Workday, Greenhouse, Lever, iCIMS, BambooHR), formatting fallback\nrecommendations when ATS compatibility conflicts with visual design.</p>\n<h1>============================================================\nPHASE 3: KEYWORD MATCHING ALGORITHMS</h1>\n<p>Step 3.1 -- Keyword Extraction from Job Descriptions</p>\n<p>Evaluate: extraction method (regex, NLP entity recognition, TF-IDF, LLM-based),\nkeyword categorization (hard skills, soft skills, certifications, tools, industry\nterms), required vs. preferred keyword distinction, keyword frequency weighting,\ncontextual extraction (understanding \"3+ years of Python\" as both a skill and\nexperience requirement), multi-word keyword handling (\"machine learning\" as one\nkeyword, not two).</p>\n<p>Step 3.2 -- Resume-to-Job Matching</p>\n<p>Evaluate: matching methodology (exact match, semantic similarity, synonym expansion),\nmatch scoring algorithm (binary present/absent, weighted by importance, frequency-\nbased), skill synonym database quality (\"JavaScript\" = \"JS\" = \"ECMAScript\"),\nexperience level matching (entry-level resume against senior job -- mismatch\ndetection), industry context awareness (same skill name different meaning across\nindustries), negative keyword handling (skills or terms to avoid).</p>\n<p>Step 3.3 -- Gap Analysis and Recommendations</p>\n<p>Evaluate: missing keyword identification from job description, keyword placement\nrecommendations (which section to add missing keywords), keyword stuffing detection\nand prevention, natural language integration suggestions (not just listing keywords),\npriority ordering of missing keywords (required vs. nice-to-have), transferable\nskill suggestions (related skills the candidate has that partially match).</p>\n<h1>============================================================\nPHASE 4: FORMATTING AND DESIGN</h1>\n<p>Step 4.1 -- Template Quality</p>\n<p>Evaluate: template variety (number, industry-specific, experience-level appropriate),\ntemplate responsiveness (content adapts to resume length -- 1-page, 2-page),\ntypography quality (readable fonts, appropriate sizes, consistent hierarchy),\nwhitespace and margin handling, print-friendliness, color usage (accessible\ncontrast, professional appearance), section ordering flexibility.</p>\n<p>Step 4.2 -- Content Formatting</p>\n<p>Evaluate: bullet point formatting consistency, date alignment, heading hierarchy,\nskill section display options (list, grid, proficiency bars, tags), experience\nentry layout, education entry layout, multi-column support (when ATS-safe),\npage break handling (no orphaned headers, no split entries across pages).</p>\n<p>Step 4.3 -- Length Optimization</p>\n<p>Evaluate: resume length guidance (1-page for early career, 2-page for experienced),\ncontent prioritization when space is limited, section reordering based on relevance,\nachievement condensation suggestions, redundancy detection (same skill listed in\nmultiple places), content density scoring (too sparse vs. too cramped).</p>\n<h1>============================================================\nPHASE 5: ACHIEVEMENT QUANTIFICATION</h1>\n<p>Step 5.1 -- Achievement Detection</p>\n<p>Evaluate: whether the system identifies vague bullet points (\"Responsible for managing\nteam\" vs. \"Led 12-person team that delivered $2M project 3 weeks ahead of schedule\"),\naction verb detection and suggestion, quantification prompts (revenue, percentages,\nteam size, time saved, cost reduced), result-oriented language encouragement\n(STAR/CAR framework support).</p>\n<p>Step 5.2 -- Quantification Assistance</p>\n<p>Evaluate: guided quantification workflows (prompts to add numbers to vague bullets),\nindustry-specific quantification templates, achievement example libraries by role\nand industry, before/after bullet comparison, metric suggestion based on job function\n(sales: revenue and quota; engineering: system uptime and latency; marketing:\nconversion and engagement).</p>\n<p>Step 5.3 -- Impact Scoring</p>\n<p>Evaluate: bullet impact scoring methodology (weak, moderate, strong), per-bullet\nimprovement suggestions, overall resume impact score, achievement relevance to\ntarget job, achievement recency weighting (recent achievements weighted more\nheavily), leadership and scope indicators.</p>\n<h1>============================================================\nPHASE 6: SKILL EXTRACTION ACCURACY</h1>\n<p>Step 6.1 -- Extraction from Resume Text</p>\n<p>Evaluate: skill identification from unstructured text (experience bullets, project\ndescriptions), extraction accuracy (precision and recall), false positive handling\n(mentioning a technology is not the same as proficiency), skill contextualization\n(used vs. managed vs. designed with a technology), extraction from non-standard\nformats (creative resumes, portfolios).</p>\n<p>Step 6.2 -- Skill Normalization</p>\n<p>Evaluate: skill synonym resolution, skill hierarchy mapping (React is a JavaScript\nframework), skill categorization (programming languages, frameworks, databases,\nsoft skills, methodologies), skill currency detection (outdated technologies\nflagged), proficiency level inference from context (\"expert in\" vs. \"familiar\nwith\" vs. \"exposure to\").</p>\n<p>Step 6.3 -- Skill Gap Visualization</p>\n<p>Evaluate: visual comparison of candidate skills vs. job requirements, coverage\npercentage by skill category, gap severity weighting (missing required skill vs.\nmissing preferred skill), skill transferability suggestions, competitive positioning\n(how this skill profile compares to typical applicants).</p>\n<h1>============================================================\nPHASE 7: JOB-DESCRIPTION ALIGNMENT SCORING</h1>\n<p>Step 7.1 -- Overall Alignment Score</p>\n<p>Evaluate: scoring methodology (weighted keyword match, semantic similarity, experience\nlevel alignment, education match), score components and transparency (can users see\nwhat drives the score), score calibration (does a high score correlate with interview\ncallbacks), industry-specific scoring adjustments, multi-job comparison (score resume\nagainst multiple jobs simultaneously).</p>\n<p>Step 7.2 -- Per-Section Alignment</p>\n<p>Evaluate: section-level scoring (how well does each resume section align with the\njob), section improvement recommendations prioritized by impact, content reordering\nsuggestions based on job alignment, tailored summary/objective generation for\nspecific jobs, experience bullet reordering (most relevant first).</p>\n<p>Step 7.3 -- Iterative Optimization</p>\n<p>Evaluate: optimization workflow (score, adjust, re-score cycle), score improvement\ntracking per revision, diminishing returns detection (further changes won't\nsignificantly improve score), over-optimization warning (resume sounds artificial),\nversion management (save tailored versions per job application).</p>\n<p>Write analysis to <code>docs/resume-optimizer-analysis.md</code> (create <code>docs/</code> if needed).</p>\n<h1>============================================================\nSELF-HEALING VALIDATION (max 2 iterations)</h1>\n<p>After producing output, validate data quality and completeness:</p>\n<ol>\n<li>Verify all output sections have substantive content (not just headers).</li>\n<li>Verify every finding references a specific file, code location, or data point.</li>\n<li>Verify recommendations are actionable and evidence-based.</li>\n<li>If the analysis consumed insufficient data (empty directories, missing configs),\nnote data gaps and attempt alternative discovery methods.</li>\n</ol>\n<p>IF VALIDATION FAILS:</p>\n<ul>\n<li>Identify which sections are incomplete or lack evidence</li>\n<li>Re-analyze the deficient areas with expanded search patterns</li>\n<li>Repeat up to 2 iterations</li>\n</ul>\n<p>IF STILL INCOMPLETE after 2 iterations:</p>\n<ul>\n<li>Flag specific gaps in the output</li>\n<li>Note what data would be needed to complete the analysis</li>\n</ul>\n<h1>============================================================\nOUTPUT</h1>\n<h2>Resume Optimizer
