You retype the same instructions to Claude every day

"Summarize this article in 5 bullets." "Sort these leads by priority." "Triage my emails and draft the replies." You already know the perfect procedure, but you retype it in every conversation. Three minutes here, two minutes there. Add it up over a month and it's hours.

A Claude skill is that procedure saved once. You describe it in plain language, you save it, and Claude triggers it automatically the moment your message matches. It works in Claude.ai and in Claude Code.

⚙️How it works
1
Trigger. You send a message to Claude. It compares your sentence to the description field of your skills and picks the one that matches best.
2
Execution. The body of the skill (your step-by-step instructions) becomes the plan. Claude follows it in order, without you having to explain it.
3
Result. You get the expected output (recap, draft, ranking, report) in the format you defined once and for all.

You click, you describe, Claude writes your skill

No coding needed. Two possible surfaces, the result is the same.

Claude.ai — recommended
You click on Create a skill with Claude. No file to write by hand.
⌨️
Claude Code — also possible
You launch claude in the terminal and type "create a skill that…". The agent does the same.

The 5 clicks

📍 claude.ai → Customize → Skills
⚙️From your manual task to a skill that triggers itself
1
Identify a task you do more than twice a week. Triaging emails, summarizing articles, drafting client messages, sorting leads, briefing a designer. If you do it twice, you'll do it 200 times.
2
Open Customize → Skills. In the Claude.ai sidebar, click Customize, then the Skills tab. You'll see the list of your existing skills (empty at first, that's normal).
3
Click + then Create a skill with Claude. A mini-conversation opens. You don't have to write any YAML, JSON, or markdown. Claude takes over and asks you the right questions.
4
Describe your task in plain English, like to an intern. "When I say X, you do Y in this order, and you hand me back Z in the following format." Be explicit about the output format (table, bullets, draft, code). See the example below.
5
Claude writes the skill, you review, you click Save. It generates the SKILL.md, shows it to you, and asks you to confirm. You can iterate by asking for tweaks ("add a newsletters category") before saving. Once saved, the skill is available right away.

Full example: a skill that triages your Gmail inbox

The brief to paste, word for word, into Create a skill with Claude:

I want a skill that sorts my Gmail inbox.

When I say "sort my emails" (or "give me a rundown of
my inbox", "draft the urgent replies"), you:

1. Read the 20 most recent unread emails in my inbox via
the Gmail MCP (not the social or promotions categories).

2. Classify each email into 4 categories:
   - URGENT: reply expected within 24h, direct question
     from a client, explicit deadline
   - TO HANDLE: info request that can wait 2-3 days
   - INFO: newsletter, notification, no-reply
   - TO ARCHIVE: promo, spam, no value

3. For each URGENT email: read the thread for context,
draft a reply of 3 to 5 lines max keeping the sender's
tone, and create the draft in Gmail.

4. Show me a recap table (category / count / action),
then the list of created drafts (subject + recipient).

Name this skill "gmail-triage".
What happens next

You don't write a single line. Claude shows you the generated skill, asks you to confirm, then saves it. From the very next conversation, you write "sort my emails" and the agent runs the 4 steps on its own: recap table + urgent drafts ready in Gmail.

Prerequisite

The Gmail connector must be active (Customize → Connectors → Gmail). Without it, the skill triggers but can't read your inbox. Turn it on before the final test.

Now it's your turn to write one

Pick a task you did 3 times this week, copy the Gmail Triage template above, swap out the content. You'll have your first agent in 10 minutes.
