Claude Skills: Stop Explaining Yourself Twice

If you keep pasting the same format, rules, and examples into Claude, you do not have a prompting problem. You have a workflow with nowhere to live.

Claude Skills give that workflow a home. You set up the instructions once, then Claude can apply them when you ask for the kind of work they cover. No more hunting for a massive prompt in an old note every time you start a new chat.

A Skill Is a Small, Reusable Playbook

The name makes it sound more mysterious than it is. A Skill is a folder with one required file, SKILL.md.

At the top is a short header with the Skill's name and description. Below that are plain-English instructions for a recurring task. It is the same briefing you would give a sharp new hire before handing them a job you do every week.

A weekly client update Skill, for example, can tell Claude how to group raw notes, what internal chatter to remove, the output format to use, and the question to end on. That knowledge stops living in your head or in a pasted prompt.

The useful part of AI is not a clever answer once. It is a reliable process you can use again.

The Description Line Decides Whether It Gets Used

The body of a Skill tells Claude what to do after it has chosen the Skill. The description is what helps Claude decide the Skill is relevant in the first place.

This is vague:

description: Helps with client updates.

This gives Claude something useful to match:

description: Writes a weekly client status update from raw notes. Use when the user asks for a client update, status email, Friday update, weekly recap, or wants messy notes turned into a client-ready summary.

Say what the Skill produces. Say when it should be used. Use the phrases a real person would use when asking for that work.

Start With the Task You Keep Re-Explaining

Do not try to turn your whole job into a Skill on day one. Pick the one repeated task that is already annoying: a client update, a meeting recap, a proposal draft, a support-response format, or a way of turning messy notes into useful fields.

Write four short sections:

• Purpose: What this produces.
• Process: The steps to follow.
• Rules: The constraints you otherwise correct by hand.
• Example: A real input and the shape of a good output.

The example matters more than most people expect. "Be concise" can mean ten different things. A before-and-after example tells Claude exactly what good looks like.

There are a few practical details worth getting right. Save the file as SKILL.md inside the matching folder. When you upload it, zip the folder, not the file. And only use Skills from people you trust, because a Skill is still a set of instructions Claude may follow.

Start with one thing you keep explaining. Make that work reusable. Then use the time you get back on something that actually needs your judgment.
