What Hubspot Pack is
Hubspot Pack is a plugin published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. The repository describes itself as: “Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com.”
A plugin is a package that bundles skills, slash commands, subagents, hooks, and MCP connectors so they install together. Plugins are plain files with a manifest at .claude-plugin/plugin.json, and they work in both Claude Code and Claude Cowork.
Installing Hubspot Pack adds everything it ships in one step. Connectors inside a plugin still need to be connected separately, and hooks and subagents only run in Cowork and Claude Code, not in regular chat.
How to install Hubspot Pack
Claude Code
- Add the repository as a plugin marketplace: claude plugin marketplace add jeremylongshore/tons-of-skills-marketplace
- Install the plugin: claude plugin install hubspot-pack@<marketplace-name>, using the marketplace name from the repository's .claude-plugin/marketplace.json.
- Restart the session if the new skills or commands don't appear straight away.
Claude Cowork
- Open Customize → Plugins and choose Add marketplace.
- Enter jeremylongshore/tons-of-skills-marketplace (the owner/repo shorthand works for GitHub).
- Find Hubspot Pack in the list, click Install, then connect any connectors it needs from its Connectors tab.
New to extending Cowork? Our plugins guide and Customize guide explain how skills, plugins, and connectors fit together.

> Claude Code skill pack for HubSpot CRM integration -- 10 production-engineer skills built from a real-world pain catalog, covering auth, webhooks, dedup, migrations, pipeline automation, and rate-limit survival on the CRM v3 API.
What is HubSpot?
HubSpot is a CRM platform for marketing, sales, and customer service. The HubSpot API (v3) provides programmatic access to CRM objects (contacts, companies, deals, tickets), marketing tools (emails, forms, lists), and automation (webhooks, workflows). The official Node.js SDK is @hubspot/api-client.
Pack Overview
Version 2.0.0 is a deliberate rebuild: the original 30 template skills were replaced by 10 deeper, pain-catalog-grounded skills written for production engineers. Each skill targets the failure modes that actually burn HubSpot integrations — wrong-winner merges, webhook replay storms, portal quota exhaustion, cross-portal contamination — using real HubSpot API endpoints (/crm/v3/objects/*), the actual @hubspot/api-client SDK, and documented error responses.
Installation
/plugin install hubspot-pack@claude-code-plugins-plusQuick Start
npm install @hubspot/api-client
export HUBSPOT_ACCESS_TOKEN=pat-na1-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxximport * as hubspot from '@hubspot/api-client';
const client = new hubspot.Client({
accessToken: process.env.HUBSPOT_ACCESS_TOKEN!,
numberOfApiCallRetries: 3,
});
// Create a contact
const contact = await client.crm.contacts.basicApi.create({
properties: { email: '[email protected]', firstname: 'Jane', lifecyclestage: 'lead' },
associations: [],
});
// Search contacts
const results = await client.crm.contacts.searchApi.doSearch({
filterGroups: [{
filters: [{ propertyName: 'lifecyclestage', operator: 'EQ', value: 'customer' }],
}],
…Skills Included
Key HubSpot API Concepts
- Base URL: https://api.hubapi.com
- Auth: Private app access tokens (pat-na1-*) or OAuth 2.0
- Rate limits: 10 requests/second, 500,000/day (shared per portal)
- Batch limit: 100 records per batch operation
- Search limit: 10,000 results maximum (use getPage for full exports)
- SDK package: @hubspot/api-client (not @hubspot/sdk)
Usage
Skills trigger automatically when you discuss HubSpot topics:
- "Set up HubSpot auth for production" triggers hubspot-auth
- "Our webhook handler is double-processing events" triggers hubspot-webhook-handlers
- "I'm getting 429s from HubSpot" triggers hubspot-rate-limit-survival
- "We have thousands of duplicate contacts" triggers hubspot-contact-dedup

Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
