Email Drafting
Pure reasoning skill for writing cold emails. No scripts, no tools — just frameworks, patterns, and examples from real campaigns that consistently generate replies.
When to Use
Use this skill when:
User says "write a cold email", "draft outreach", "help me with email copy", "write a sequence"
Any task requires cold email copy — subject lines, full sequences, or individual emails
Phase 0: Intake
Collect campaign context before writing anything. Ask all questions at once, organized by category. Skip any the user has already answered.
Campaign Context
What product/service are you selling?
What problem does it solve? Who feels this pain most acutely?
