When to Use This Skill

• Enhancing weak resume bullets into quantified achievements
• Analyzing ATS compatibility of a resume
• Generating multiple resume versions for different roles

Core Workflow

Step 1: Gather Information

Collect the candidate's data in this order. If the user provides a JSON blob or existing CV, parse it first and ask only about gaps.

1. Personal info — name, email, phone, location, LinkedIn/GitHub (optional)
2. Target role — job title, industry, experience level, and optionally a job description to tailor against
3. Experience — for each position: title, company, dates, responsibilities, and achievements
4. Education — degree, institution, year, GPA (if strong)
5. Skills — technical, tools, soft skills
6. Projects, certifications, languages — if relevant

For the input data structure, see references/input_schema.md.

Step 2: Enhance Content

Transform raw information into compelling, ATS-optimized content.

Professional Summary Formula:

[Job Title] with [X] years of experience in [industry/domain].
Proven expertise in [3-4 key skills].
Track record of [1-2 major achievements with numbers].
Seeking to leverage [specific skills] to [value proposition for target role].

Experience Bullet Formula:

[Action Verb] + [What you did] + [How you did it] + [Result with numbers/impact]

Examples of the transformation:

Before: "Responsible for managing social media accounts" After: "Increased social media engagement by 145% over 6 months by implementing data-driven content strategy across 4 platforms, resulting in 12,000 new followers"

Before: "Worked on improving team productivity" After: "Led agile transformation for 15-person engineering team, reducing sprint cycle time by 30% and increasing on-time delivery from 65% to 92%"

Before: "Developed software applications" After: "Architected and deployed microservices-based e-commerce platform serving 50K+ daily users, reducing page load time by 40% and increasing conversion rate by 18%"

Key principles for enhancement:

• Quantify everything — replace vague statements with measurable achievements
• Action verbs — start bullets with strong verbs (Led, Developed, Increased, Reduced, Implemented)
• ATS keywords — naturally incorporate relevant keywords from the job description
• Impact focus — show results, not just responsibilities
• Concise — 1 page for <5 years experience, 2 pages for senior roles
• No pronouns — never use "I", "me", "my"
• Consistent tense — past tense for previous roles, present for current

For the complete list of power verbs by category, see references/power_verbs.md.

Step 3: ATS Optimization

Ensure the document passes automated screening systems:

1. Use standard section headings: "Professional Summary", "Work Experience", "Education", "Skills"
2. Include exact keywords from job description (don't paraphrase)
3. Spell out acronyms first: "Application Programming Interface (API)"
4. Use standard date formats: "Jan 2020 – Present"
5. Avoid tables, text boxes, headers/footers, images
6. Use simple bullet points (•) not fancy symbols
7. Stick to common fonts: Arial, Calibri, Times New Roman

Resume Sections Order:

1. Contact Information (name prominent at top)
2. Professional Summary (3–4 lines)
3. Skills (categorized: Technical, Tools, Languages)
4. Work Experience (reverse chronological)
5. Education
6. Certifications (if relevant)
7. Projects (for tech roles or freshers)

Step 4: Generate Cover Letter (If Requested)

Structure:

• Opening — hook with enthusiasm, mention specific role, one-line value prop
• Body 1 — 2–3 most relevant experiences connected to job requirements with specific results
• Body 2 — demonstrate understanding of company mission, show cultural fit
• Closing — reiterate enthusiasm, request interview, thank them

Tone: professional but warm, confident without arrogance, specific not generic. Match company culture (formal for finance, casual for startup). Show genuine research about the company.

Step 5: Quality Check

Before delivering, verify with this checklist:

Resume:

• [ ] No grammatical errors or typos
• [ ] All bullets start with action verbs
• [ ] At least 60% of bullets include quantifiable results
• [ ] Length appropriate for experience level
• [ ] No personal pronouns
• [ ] Consistent date formatting
• [ ] Contact info complete and professional
• [ ] ATS-friendly format (no tables/images/complex layouts)
• [ ] Critical keywords from JD incorporated naturally

Cover Letter:

• [ ] Personalized — mentions company and role specifically
• [ ] No generic phrases like "I am writing to apply..."
• [ ] Shows research about company
• [ ] Tells a story, doesn't repeat resume
• [ ] Includes specific achievements with numbers
• [ ] 3–4 paragraphs, ~300–400 words

Industry-Specific Customization

Adapt emphasis, metrics, and sections based on industry:

| Industry | Emphasize | Key Metrics | |----------|-----------|-------------| | IT/Software | Technologies, frameworks, system scale | Users served, uptime %, load time improvements | | Finance/Banking | Regulatory compliance, risk management | Cost savings, ROI, portfolio growth | | Sales/Marketing | Revenue growth, pipeline generation | % growth, deals closed, leads generated | | Healthcare | Patient care, clinical outcomes | Patient satisfaction, efficiency gains | | Creative/Design | Portfolio projects, brand impact | Engagement rates, campaign reach, awards |

Output Format

Return output in this structure:

# [Document Type]: [Candidate Name]

## Target Role
[Job Title] at [Company Name (if applicable)]

## Content
[Full formatted resume/cover letter text]

## Metadata
- Word Count: [number]
- ATS Score: [X/100] (if JD provided)
- Key Keywords Included: [list]
- Recommended File Name: [FirstName_LastName_DocumentType.pdf]

## Notes
[Specific recommendations or customization suggestions]

Error Handling

• Incomplete data — identify missing critical fields, request specifics, suggest alternatives (e.g., use education projects if no work experience)
• No job description — generate a generic optimized resume for the role/industry, suggest providing a JD for better tailoring
• Weak experience — focus on transferable skills, highlight education/projects/certifications, emphasize learning agility
