Our Enterprise AE Jan Rasmussen runs his entire GTM stack from Claude Code. The terminal pushes actions straight into Slack, Apollo, Lemlist, Notion, HubSpot, Linear, Typefully, and 10 other tools.

He built it out of Claude Code skills and hooks.

A skill is a SKILL.md file the agent loads when the work calls for it. It tells Claude how to do one GTM job, like building a campaign or enriching a lead. Six of those ship in the repo.

A hook is a settings.json entry that fires on a specific Claude Code event, like a task finishing or a tool running. Behind each one is a Python handler that hits the right REST API.

→ Claude finishes a task → Slack pinged

→ Claude enriches a lead → CRM updated

→ Claude writes a sequence → Lemlist starts it

→ Claude drafts content → Typefully queues it

He wrote skills and wired hooks one job at a time, until each piece of his week stopped being his problem. Then he open-sourced the whole thing.

What's in the repo:

• 30 hooks across 8 categories

• 17 integrations

• 6 GTM skills (campaign-builder, lead-enrichment, personalization-writer, pipeline-reviewer, reply-classifier, signal-monitor)

• 7 subagents plus the /outbound-pipeline slash command that chains them into a 5-stage workflow

• 17 content prompts

• 5 role-based starter packs (founder, sales, marketing, ops, design)

For years, real GTM engineering meant knowing Clay and having someone who could code. Repos like this one are flattening that.
