B2B Lead List Builder — ICP to Outreach-Ready Lists

Your pipeline dies at the top of the funnel. Most lead lists are built on a vague ICP, stale data, guessed emails, and zero verification — then the bounce rate kills your domain and the replies never come. You don't have a closing problem. You have a list problem.

B2B Lead List Builder is a professional AI skill that turns any ICP description into a complete, executable lead-list build plan — in one run:

1. ICP Definition Worksheet — firmographics, technographics, trigger events, buyer personas, explicit disqualifiers, approved by you first
2. Source Triangulation Plan — 3+ lawful public sources cross-checking each other, every company confirmed in 2+ independent sources
3. Enrichment Schema — exact fields per lead row
4. Verification Checklist + Bounce-Risk Scoring 0–100, tiered green/yellow/red
5. Outreach-Ready CSV Spec with dedup rules and sample rows
6. Compliant Outreach Guidance — permission basis, unsubscribe, volume/deliverability, suppression lists
7. List-Hygiene Routine

Includes SKILL.md (7-phase methodology v1.0.0), scoring rubric, and a complete fictional example report.

My honest word: this produces a build plan and spec — not a database of leads. Lawful public sources only, never private data; pattern-suggested emails are always labeled unverified; no deliverability guarantees; and it's not legal advice. If it doesn't deliver the plan it promises, Agensi's money-back guarantee covers you — I put my name on every skill.
