The skill was mining/online-sleuthing heavy and thin on primary
research. Add an interviews + surveys layer so agents can help users
go ask customers directly, not just observe them in public.
New references/interviews-and-surveys.md covers the Sean Ellis /
Superhuman PMF survey (the "no longer use" question plus the 40% "very
disappointed" benchmark, Superhuman's 58%), Keep-Asking-Why 5-why
laddering with a churn-to-NRR worked example, a best-customers CRM
recruiting method, incentive guidance ($50/call, $5/survey; aim 10,
happy with 5), an outreach email template, Amy Hoy's Sales Safari,
and the confirmation-bias guardrail (prove yourself wrong; Dropbox).
Adapted from Founding Marketing ch.2.
SKILL.md gains a Mode 3 (primary research) that routes to the new
reference; description adds primary-research triggers; new eval id 13.
