- Claude Code 2.x
Wrote first-touch emails for 15 real (anonymized) prospects; personalization referenced verifiable specifics, not "I loved your recent post" filler. 3 replies from a 15-send test batch.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 5/5
- Output vs. baseline 9/10
- Docs & honesty 4/5
What it does
The highest-stakes sales skill: one templated line kills the thread. This one forces research-backed personalization and short, single-CTA structure. Our live send test got replies, which is the only metric that matters.
Before / after — same task, with and without the skill
Without the skill

With Cold Email
Hi Dana — Northwind's careers page added three RevOps roles last month; that's usually when CRM hygiene starts hurting. We cut manual entry 34% for Loop. Worth 15 minutes Thursday?
