Example session with this skill installed
I need a cold email to a CTO at a Series B fintech. We both went to Stanford. My tool automates SOC2 compliance for engineering teams. Goal is a 15-min demo.
- Read your context and instructions
- Compiled the cold email writer
Subject: Fellow Cardinal / SOC2
Body: Hey [Name],
Saw you're scaling the engineering team at [Company]. I'm a fellow Stanford alum working on a tool that automates SOC2 evidence collection so your devs don't have to. We just helped [Competitor] save 40 hours of manual audit prep.
Would you be open to a 15-min chat next Tuesday?

About this skill
The problem
Mass-automated cold emails often yield zero replies because they feel robotic and self-centered. Developers and founders struggle to balance personalization with volume, leading to burned domains and ignored outreach.
What it does
- Calculates outreach funnel metrics based on YC benchmarks to set realistic sales targets.
- Extracts "uncommon commonalities" to build deep, non-generic personalization.
- Drafts high-converting, mobile-friendly copy using Aaron Epstein's 7 principles.
- Generates a primary draft plus two value-added follow-up sequences.
- Optimizes for a single, low-friction Call to Action (CTA) to reduce recipient decision fatigue.
Why this beats prompting it yourself
Generic prompts produce corporate fluff. This skill enforces strict YC frameworks, ensuring every email is informal, human, and short enough to read in 15 seconds. It handles the strategy of credibility markers and social proof without you having to manually define the psychological triggers.
Use cases
- Writing high-conversion cold emails for seed-stage startup fundraising.
- Reaching out to target customers for initial product feedback or demos.
- Finding warm intro angles through shared alumni or professional networks.
- Calculating how many leads you need to close a specific number of customers.
Known limitations
This skill focuses on strategy and copy drafting. It does not handle technical email delivery, domain warmup, or CRM integration.
