How a skill loads

Three layers. Only the first one is always on.

Skills use progressive disclosure. Claude reads a short line about every skill, then opens the full instructions only when a task matches. Tap a layer to see where it lives in the folder.

meeting-minutes/├── SKILL.md # name + description│ └── body # when to use, steps, rules├── reference/│ └── house-format.md├── scripts/│ └── extract_actions.py└── assets/ └── minutes-template.docx

Layer 1 lives in the frontmatter at the top of SKILL.md. Claude keeps this line for every installed skill in mind and uses it to decide what to open.

Skill builder

Write a SKILL.md that actually triggers.

Fill in the fields and the file writes itself. The checks are the same ones we run before a skill goes into the library.

Lowercase letters, numbers and hyphens.
Say what it does and when to use it. Claude only sees this line until the skill triggers.

---
name: invoice-chaser
description: Drafts polite, firm reminder emails for overdue invoices with the amount, due date and payment link. Use when the user mentions an unpaid or overdue invoice or asks to chase a payment.
---

# Invoice Chaser

## When to use
- Any request that matches the description above

## Steps
1. Find the client name, invoice number, amount and due date.
2. Pick the tone from days overdue: friendly under 14, firm after 30.
3. Write a subject line and an email under 120 words with the payment link.
4. Offer a follow up date.

## Rules
- Never threaten legal action unless the user asks.
- Always restate the exact amount and invoice number.
Install anywhere

Same folder, three places to run it.

A skill is a folder with a SKILL.md inside. Where you put that folder depends on how you use Claude. Menu names change over time, so check Anthropic's docs if a label looks different.

01

Turn on skills

Open Settings in the Claude app and find the Skills section. Code execution needs to be on, since many skills run scripts.

02

Zip the folder

Zip the skill folder so the SKILL.md sits inside a folder named after the skill, like meeting-minutes/SKILL.md.

03

Upload it

Upload the zip in the Skills section. Anthropic's official skills are already listed there to switch on.

04

Just ask

Ask for the task in normal words. Claude reads the description and loads the skill when it matches.

Questions

Before you stack.

What is a Claude Skill?

A folder of instructions, and optionally scripts and reference files, that teaches Claude how to do one kind of task your way. Claude loads it on its own when your request matches the skill's description, so you stop pasting the same long prompt every time.

Is the Skills Library free?

Yes, for a limited time every skill in the library, including the full SKILL.md files, the builder and the install script, is free to use with no sign-up.

How many skills can I install?

There is no small practical cap. An idle skill costs only its name and description, roughly 100 tokens. The real limit is clarity: when two descriptions overlap, Claude can pick the wrong one, so keep each skill focused on one job.

My skill never triggers. Why?

Almost always the description. It needs the words people actually type, like slides, deck or invoice, and a clear use when clause. Run it through the builder on this page or the skill-auditor in the library.

Are skills safe to install?

Only install skills you trust or have read. A skill can include scripts that Claude runs, so treat a skill like any other code: read the SKILL.md and every script before you add it. Every GeeklyPlug skill here shows its full SKILL.md before you install.

What is the difference between a skill and a project or custom instructions?

Custom instructions and project knowledge are always in context. A skill sits idle until a task needs it, can carry code and files, and works the same way across the Claude app, Claude Code and the API.

Where do the official skills come from?

Cards marked Anthropic point to Anthropic's public skills repository on GitHub. We show a summary here and link to the real files, since that repo is the source of truth.

Need a skill built around your exact workflow?

We write, test and tune custom skills for teams: your formats, your tone, your tools. Every skill ships with trigger tests and a plain-English readme.
