How to Create a Reusable AI Skill

This guide covers what should go inside of a SKILL.md and explores multiple methods for creating a skill: from fully manual to fully AI automated.

Notion Task Manager Skill

"/notion-task-manager" parses brain dumps, bullet lists, meeting notes, or voice transcripts into structured Notion tasks with inferred title, project, owner, priority, and deadline. It then creates them in the right database and confirms what was added. To install, run this in your terminal after downloading the file: unzip ~/Downloads/notion-task-manager-skill.zip -d ~/.claude/skills/notion-task-manager/

A Skill for Creating Skills

"/skill-creator" is Anthropic's official skill that creates new skills from scratch, modifies and improves existing skills, runs evals to test skill performance, and benchmarks skills with variance analysis and description optimization. To install, run this in your terminal after downloading the file: unzip ~/Downloads/skill-creator-skill.zip -d ~/.agents/skills/skill-creator/

Meeting Prep Skill

"/meeting-prep" generates a pre-meeting brief by pulling upcoming calendar events, searching Notion for relevant project context, and scanning Slack for recent conversations. This is all synthesized into a one-page brief covering purpose, outcomes, open questions, and prep notes. To install, run this in your terminal after downloading the file: unzip ~/Downloads/meeting-prep-skill.zip -d ~/.claude/skills/meeting-prep/

Summarize Slack Skill

"/slack-digest" summarizes recent Slack activity by searching for action items, decisions, and key updates across project channels and collaborator messages. It outputs a signal-only digest organized into 'Need Your Attention', 'Key Decisions', and 'FYI'. To install, run this in your terminal after downloading the file: unzip ~/Downloads/slack-digest-skill.zip -d ~/.claude/skills/slack-digest/

Giving Context to Your Agents: Making Your First CLAUDE.md

CLAUDE.md is a plain text file that loads automatically at the start of every Claude Code or Cowork session. It tells Claude who you are, what you are working on, what tools you use, and how you want Claude to behave.

How to Automate Recurring Work in Cowork

Claude Cowork is an Anthropic tool available in the Claude Desktop app that can access your full computer and help you to automate your tasks.

Build a Quality Rubric for Your AI Workflow

A quality rubric is a set of explicit, measurable criteria that define what a good output looks like for a specific task. It answers the question: "How do I know when this is good enough to use?"

Claude Chat vs. Cowork vs Code

There are a lot of options for how to approach tasks using AI. Learn which interface to reach for why one might be more suited to specific tasks than the others.

How to Set Up MCP Connections

MCP stands for Model Context Protocol. It's the standard that lets AI models connect to external tools, your calendar, email, Slack, Notion, databases, and more.

Three Types of AI Memory

There are three types of AI memory: in-context memory, file-based memory, and retrieved memory. This reference card outlines examples of each and tips for how to prioritize how you save and transfer data to AI Agents.

Create Scheduled Tasks in Claude

Learn a quick an easy way to set up automated tasks using either Claude Cowork or Claude Code.

Tutor Skill

"/teach-me" acts as an adaptive conversational tutor that assesses baseline knowledge, builds a learning roadmap, teaches with analogies, checks understanding at each step, and closes with a summary and resources. To install, run this in your terminal after downloading the file: unzip ~/Downloads/teach-me-skill.zip -d ~/.claude/skills/teach-me/

Slash Commands for AI Applications and Terminal

Learn what slash commands are, how they work, and what commands you'll use most when working with agents like Claude.

AI Agents vs. Skills: How to Know What to Build

AI Agents and Skills handle tasks in fundamentally different ways. You don't want to create a custom agent when a simple skill will suffice, but a skill won't have the same scope an agent would. This guide outlines the differences between the two approaches and their use cases.

Startup Financial Modeling Skill

"/startup-financial-modeling" will build comprehensive 3-5 year financial models for early-stage startups, covering cohort-based revenue projections, cost structure, burn rate, runway, headcount planning, and fundraising scenario analysis. To install, run this in your terminal after downloading the file: unzip ~/Downloads/startup-financial-modeling-skill.zip -d ~/.agents/skills/startup-financial-modeling/

Three Principles for AI Coding

These three principles form the foundation of effective AI-assisted development. Master them and you'll ship better code faster.

Email Manager Skill

"/email-manager" triages the user's inbox, sorts emails by urgency, skips noise, and produces ready-to-review reply drafts in the user's voice without sending anything automatically. To install, run this in your terminal after downloading the file: unzip ~/Downloads/email-manager-skill.zip -d ~/.agents/skills/
