What it is and why it matters

Cold Outbound Skills is a repo of skills for cold email and outbound sales from Claude Code. It gathers your company context (site, offer, ICP, case studies) and your total addressable market, then proposes campaigns and experiments, reviewing which messages got the best positive reply rate. The author frames it as a weekly test-and-learn loop, always with human approval.

Key points

Generates context files (ICP, value proposition, case studies) from your site
Locks the CTA to avoid campaigns that accidentally give the product away
Weekly loop: reviews past performance and suggests the next batch

Where we saw it

Eric Nowoslawski 2026-05-31 The author explains that, rather than copying Karpathy's Auto Research repo, he took its idea: optimize one specific number, the positive reply rate. The system gathers company context and builds the whole target market up front so the agent does not improvise; it then creates experiments and proposes contacts and copy with human approval. He mentions email verification via Million Verifier and a locked CTA as safeguards. He reports one customer case where reply rate doubled, with the caveat that it is a single case.
