cold-email is an agent skill that drafts personalized B2B cold outreach emails using AIDA, PAS, and BAB copywriting frameworks for developers who need credible openers, value props, and low-friction CTAs.
About
cold-email is a user-invocable Claude Code agent skill from humanizerai/agent-skills that generates reply-focused cold outreach from three inputs: target (role, company, industry), goal (meeting, intro, feedback, sale), and personalization context. The skill selects among three proven frameworks—AIDA, PAS, and BAB—and enforces seven hard rules including a 50-125 word body, 3-5 word lowercase subject lines, one specific CTA, and under-30-second read time. Output includes the subject, email body, framework rationale, personalization angle, and word count. Developers reach for cold-email when they need outbound copy for SaaS prospects, API integrators, or design partners without generic templates or filler phrases like "I hope this email finds you well."

Write Cold Email
Generate a cold email that gets responses using proven copywriting frameworks.
Input
Parse $ARGUMENTS for:
- Target: Who they're emailing (role, company, industry)
- Goal: What they want (meeting, intro, feedback, sale)
- Context: Personalization hooks (mutual connection, recent news, specific pain point)
If arguments are incomplete, ask for the missing pieces.
Frameworks (Choose the best fit)
AIDA (Awareness → Interest → Desire → Action)
- Hook with relevance
- Build interest with value
- Create desire with proof/benefit
- Clear CTA
PAS (Problem → Agitate → Solution)
- Identify their problem
- Make it feel urgent
- Position as the solution
BAB (Before → After → Bridge)
- Their current state (problem)
- Their ideal state (outcome)
- How you bridge the gap
Hard Rules
1. 50-125 words - Shorter emails get more replies 2. Subject line: 3-5 words, lowercase, no clickbait 3. First line: Personalized - reference something specific about them 4. No fluff: Cut "I hope this email finds you well", "My name is...", "I wanted to reach out" 5. One CTA: Single, specific ask (not "let me know if you're interested") 6. Read time: Under 30 seconds 7. Mobile-friendly: Short paragraphs, no walls of text
What Makes It Human
- Sounds like a real person, not a template
- Has a specific reason for emailing THIS person
- Shows you did research
- Doesn't oversell or use hype words
- Has a clear "what's in it for them"
Output Format

[Email body]
[First name only]Framework used: [which one and why] Personalization: [what angle you used] Word count: [number]
