Shown in Claude. ChatGPT and Codex work the same way.

Let AI use your tools

Browser

Interacts with any website: clicks, types, captures screens.

Use the built-in browser or the Claude in Chrome extension.

Connectors

Ready-made links to apps that support Claude.

Turn one on in Claude’s settings.

MCP

Model Context Protocol: an open protocol for AI to talk to tools.

Add it as a custom connector when there’s no ready-made one.

Prompt

A colleague said you can read and edit my Google Drive, and kept mentioning something called MCP. Teach me how, or was he full of it? I have my doubts.

What is a skill?

A folder with instructions, scripts and resources. A training manual for one task.

  • ~/.claude/skills/my-slack-style/
  • SKILL.mdinstructions
  • scripts/optional
  • resources/optional
  • …

Typing the same prompt again? Make it a skill.

my-slack-style/SKILL.md
Always in context 
---
name: my-slack-style
description: Write my Slack
messages the way I do. Use for any
Slack draft or reply.
---
When matched 
1. Start with "Hej",
   end with "Lp, Nejc".
2. Short sentences. Get to the point.
3. No "I hope this finds you well".
4. English in channels, Slovene in DMs.

How a skill is loaded

  • Every skill’s name and description is always in context.
  • Claude picks the skill whose description matches the task.
  • Only that skill’s instructions are loaded into context.
Always in context

tldrSum up a long thread in three bullets. Use for long emails or threads.

Claude Code

Works in a project: a folder on your computer.

Global: ~/.claude/ · This project: {projectPath}/.claude/

CLAUDE.md

The project’s instructions: what it is and how you work.

Always in context.

Skills

This project’s skills, in {projectPath}/.claude/skills/

Loaded when a task matches.

Files

What Claude reads and makes: sheets, images, PDFs, scripts.

Saved on your computer.

In Codex: AGENTS.md and .agents/skills/

1Do it once

Solve it in a chat. Correct it with what you know.

Translate Fortune Treasure Pot’s promo text into German.
Münzen füllen den Topf. Die Topf-Funktion zahlt bis zu 1,000x.
Keep feature names in English. Write 1.000x.
Münzen füllen den Pot. Das Pot Feature zahlt bis zu 1.000x.

5Evolve

Change one skill. Everything that uses it gets the change.

Evolving means updating, adding and removing skills.

What to keep in mind

Filter

With great power comes great responsibility.

You own what you produce. Polish it before you share it. Don’t pass on slop.

Slop wastes your coworkers’ time. They could prompt AI themselves.

Compounding works both ways: slop spreads, good work multiplies.

Be curious

Know why you’re doing it. AI can show you how, and help you find the why.

  • Ask it to explain.
  • Ask why it’s done this way.
  • Ask for a different way.
  • Ask it to review how you work.

Play with it. You only learn a tool by using it.

Not covered today: scheduled tasks, cloud agents, sharing skills with a team.

What we learned

  1. 1
    Apps and tools
    Connectors and MCP let AI use your tools.
  2. 2
    Skills
    Write down what you know once. Claude loads it when a task needs it.
  3. 3
    Going beyond chat
    Claude Code works on your files, with CLAUDE.md and project skills.
  4. 4
    Compounding productivity
    Each skill builds on the last. One change improves everything that uses it.

Questions?

Your first skill

I do this task every week: [describe it]. A colleague spent an hour saying you could turn it into a skill. Prove him right, just this once.
