GTM Engineering Skills for Claude Code

AI agent skills that turn Claude Code into a GTM engineering workstation — lead enrichment, signal discovery, TAM building, and outbound automation. Powered by Deepline.

Quick Start

From Claude Code / Codex

Paste this prompt:

Install the Deepline CLI and skills using https://code.deepline.com/agent-install.txt

From the command line

curl -fsSL "https://code.deepline.com/api/v2/cli/install" | bash

Then tell Claude what you need:

> "Build a TAM of VP Sales at 50-500 person SaaS companies in the US"
> "Find LinkedIn URLs for the contacts in my CSV with identity validation"
> "Find companies in a16z's portfolio and get the Head of Growth at each"

Claude automatically picks the right skill and runs it.

What This Repo Does

These skills give Claude Code the ability to run real GTM workflows — not toy demos, but the same enrichment pipelines that GTM engineers build manually with Apollo, Hunter, PDL, and dozens of other providers.

Each skill is a markdown file (SKILL.md) that encodes:

• Which providers to call and in what order (waterfall sequences)
• How to validate results (email verification, identity matching)
• Cost optimization patterns (cheapest provider first, approval gates before expensive runs)
• Output formats (enriched CSVs, CRM updates, campaign imports)

Skills use the Deepline CLI under the hood — one command that orchestrates 40+ data providers (Apollo, Crustdata, PDL, Hunter, LeadMagic, Dropleads, Apify, and more) with cost-aware routing and waterfall fallbacks.
