Adding and Personalising Plugins

Add official plugins from the catalogue to build your skill library, then personalise them for your business with the Socratic interview.

On this page

The fastest way to build your skill library is to start with existing plugins rather than building skills from scratch. systemprompt.io provides a catalogue of official plugins, each targeting a specific business function with pre-built skills that work out of the box.

When you add a plugin, the platform creates a personal copy in your workspace. You own this copy and can modify, add, or remove skills without affecting anyone else.

What is a plugin?

A plugin is a bundle that extends what Claude can do. Each plugin contains a combination of:

  • Skills: Instructions that teach Claude how to handle specific tasks
  • Agents: Specialised AI assistants with defined roles
  • MCP server connections: Optional links to external platforms
  • Hooks: Automations that trigger during Claude's workflow

Plugins are starter kits. They come with sensible defaults for a specific business function. You add them to create your own copy, then personalise the skills to match how your team actually works.

Browse the plugin catalogue

Log in to systemprompt.io and click Browse Plugins in the sidebar. The catalogue displays all available plugins.

Choosing your first plugin

Start with the plugin that matches your primary role. If you are in sales, start with the Sales plugin. If you are an engineer, start with the Engineering plugin.

Do not add every plugin at once. Each plugin comes with multiple skills, and having too many unfocused skills dilutes Claude's effectiveness. Start with one or two plugins, get them working well, then expand.

Add a plugin

Adding a plugin creates a personal copy of it in your workspace. The original stays untouched. Your copy is independent — you can modify, add, or remove skills without affecting anyone else.

How to add

  1. Click on the plugin you want in the Browse Plugins catalogue
  2. Click Add on the plugin detail page
  3. The platform creates copies of all the plugin's skills and agents in your workspace

After adding, the plugin appears in your My Plugins section in the sidebar. The skills appear in My Skills. They are immediately available to Claude through your connection.

What happens when you add a plugin

When you add a plugin:

  • Each skill is copied to your personal skill library with a base_skill_id linking back to the original
  • Each agent is copied with a base_agent_id for lineage tracking
  • The copied versions are fully editable — they belong to you now
  • Your tier limits are checked (free accounts have limits on the number of plugins and skills)

Personalise with the Socratic interview

Adding a plugin gives you a copy. The Socratic interview makes that copy yours. It is a structured conversation that adapts the default skills to your specific business context.

Starting the interview

There are two ways to start the Socratic interview:

In Cowork or Claude Code: Type /onboarding in a conversation. The system walks you through a guided discovery process.

Via the Skill Manager MCP: Ask Claude to run the onboarding interview for a specific plugin.

How the interview works

The interview runs through four phases for each plugin:

Business context. The system asks about how your organisation works. For the Sales plugin: "What does your sales process look like from lead to close? What CRM do you use? How do you research prospects before outreach?" Each plugin has questions tailored to its domain.

Data source connections (optional). For each platform the plugin supports, the interview asks whether you want to connect it. "Do you use HubSpot CRM? I can pull deal and contact data for call prep." If you say yes, it creates the connection and stores your API key as an encrypted secret. If you say no, skills continue to work in standalone mode.

Skill personalisation. The system updates each skill based on your interview answers. A call-prep skill for a team that uses MEDDPICC looks completely different from one for a product-led growth company.

Testing. After updating each skill, the interview generates test output using a real scenario and asks whether it matches your expectations. If not, it refines until you are satisfied.

Standalone vs supercharged

Every skill works without data source connections. You can paste context, describe the situation, and Claude applies the skill's instructions.

But skills become dramatically more capable with connections. A call-prep skill with HubSpot and Gmail access automatically pulls the account record, recent email threads, and deal stage. You ask "prep me for my 2pm call" and everything happens automatically.

Start without connections. Add them as you see the value. Each connection makes existing skills more capable without requiring any changes to the skills themselves.

Verify your plugins

After adding and personalising, verify everything is working:

  1. Go to My Plugins in the sidebar — your added plugin should appear
  2. Go to My Skills — the individual skills from the plugin should be listed
  3. Start a new conversation with Claude and ask: "What skills do I have available?"
  4. Ask Claude to use one of your skills on a real task
  5. Check your Control Center — the conversation should appear in the live feed

If skills are not appearing, make sure you have completed the connection setup and that the connection is active.
