You do not need every option. Choose the path your AI client supports. The stable page stays the same; versioned files are immutable.
1. Native installer
This listing has no registered native installer command. Use the complete package or source fallback below, depending on what your client supports.
Do not guess an installer command or replace an existing version without reviewing the diff.
2. Complete package recommended
Download the ZIP when available. It includes SKILL.md plus the references, security notes and version metadata.
No complete ProSkills package is published for this listing yet.3. Prompt-only
Copy the prompt above when the agent can read the stable page or when you want to adopt the workflow without installing a skill.
Need only the instruction file?
Download SKILL.md only if your client requires a single file. The complete ZIP is safer for a full installation because it preserves the references and release context.
No path installs or executes anything by itself. Your agent still needs access to the project files. Before updating, compare the installed version and review the diff.

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.

Workflows
Reference Deepline cloud workflows you can deploy with deepline workflows apply. Each is a JSON apply-payload with placeholders for IDs, channels, and secrets.
| Workflow | Use case |
|---|---|
inbound-qualification-cpg | CPG / DTC brand signups: detect retail-presence via Storepoint/Stockist/Closeby/Storerocket/Storemapper/Bullseye/Brandify locator widgets, classify CPG vs non-CPG, route to qualified/manual-review/partner-referral, draft rep brief + outbound email + LinkedIn DM |
inbound-qualification-saas | SaaS / GTM-tool signups (HubSpot webhook): enrich, classify enterprise vs agency, route to two HubSpot lists that trigger different sequences |
slack-button-listener | Listens for Approve & Send / Edit / Skip button clicks on Slack briefs and acknowledges in-thread. Pair with either inbound-qualification workflow above. |
See workflows/README.md for deployment instructions.
How It Works
You: "Find emails for the contacts in accounts.csv"
│
▼
Claude Code picks the `deepline-gtm` skill and routes to the
right recipe + provider playbook for the task.
│
▼
Skill runs the appropriate `deepline` CLI commands with the
provider waterfall, validation rules, and cost gates encoded
in the skill's instructions.
│
▼
You get: enriched CSV with verified results + provider metadata
Every enrichment opens in the Deepline Playground — a spreadsheet UI where you can inspect results, re-run failed cells, and iterate before committing to a full run.
