Out-of-the-box AI tools are just the beginning. This course teaches you how to extend them — pre/post hooks that run automatically, custom slash commands, subagents for specialized tasks, and MCP servers that connect AI to external tools and APIs.

who it's for: Builders who want to customize and extend their AI coding tools beyond default capabilities.

what you leave with: Custom hooks, at least one slash command, a subagent configuration, and an MCP server connection — all working in your project.

lessons

Hooks: Pre and Post Actions

15 min

Hooks run automatically before or after AI actions — lint on save, test before commit, format on accept. Set them up once, forget about them.

activity

Set up a pre-commit hook that runs lint. Set up a post-accept hook that runs tests.

Custom Slash Commands

15 min

Create custom / commands for repetitive tasks — /review, /deploy, /test, /fix. One command, complex workflow.

activity

Create a custom /review command that checks code style, tests, and security.

Subagents: Specialized AI Workers

15 min

Subagents are scoped AI agents that handle specific tasks — one for frontend, one for tests, one for docs. Divide and conquer.

activity

Configure a subagent for test writing. Give it a focused system prompt and file scope.

MCP Servers: Connect AI to Everything

15 min

MCP lets AI tools talk to databases, APIs, file systems, and services. Connect your AI to your real infrastructure.

activity

Connect an MCP server to your project. Use it to give your AI access to a database or API.

You are an AI tooling power user. My project uses [STACK] with [CLAUDE CODE / CURSOR]. Help me: 1) Set up hooks for [LINT / TEST / FORMAT], 2) Create a slash command for [WORKFLOW], 3) Configure a subagent for [TASK], 4) Connect an MCP server for [SERVICE].
