What this solves
Agents invent bad cold email habits unless you give them real playbooks. This pack encodes deliverability and copy rules so Claude Code reviews and writes outreach the right way.
Inbox first
Missing SPF/DKIM/DMARC or HTML-heavy first touches kill campaigns before copy matters.
Human copy
Banned phrases and AI-slop patterns get rejected. Conditional Questions replace hard meeting asks.
Agent-ready
Drop into .claude/skills/ and ask in plain English — no custom scaffolding required.
What's in the pack
