Teams can now teach Claude a repeat task once and skip the long prompt

Teams that use Claude can now save a repeat task once and have Claude apply it automatically. The feature is called a Claude skill. It replaces the long prompt people paste into each new chat. According to a HubSpot guide, skills are available on all plans, and most business workflows need no coding.

What a skill is

A skill is a folder with one required file, named SKILL.md, written in plain English. The folder can also hold reference documents, templates and scripts. Claude loads a skill only when a task matches it. Examples from the guide include an editing skill built from a company's brand guidelines and a skill that helps write step-by-step procedures.

How to build one

Claude has a built-in skill creator. A person describes the workflow in a chat, and Claude helps produce the file. The guide offers a few rules for doing it well.

• Pick one focused job, such as release notes or a weekly report. Small skills work better than one big one.
• Write down the trigger, the inputs and the output. If that takes more than a sentence each, the scope is too broad.
• Say what Claude should expect to receive, such as pasted notes or an uploaded file.
• Describe the output: format, structure, tone and length. A template file can help.

The description matters most. It is the only text Claude reads when deciding whether to use a skill. A vague or overlapping description can make Claude pick the wrong skill or none at all. Claude's documentation gives this sample: "Apply Acme Corp brand guidelines to presentations and documents, including official colors, fonts, and logo usage."

When a developer is needed

Writing instructions is different from writing code. Plain instructions suit language work, such as rewriting in a brand voice or sorting notes. Tasks like parsing a spreadsheet and summing a column are exact operations that call for scripts. Claude can generate a script, but the guide warns that checking it for mistakes can be hard without technical skill.

A developer is also needed if a skill bundles Python, Bash or Node.js scripts, which require debugging. The same goes for a skill that must reach a system Claude cannot access, or a company's own API. Someone has to set up the connection, with sign-in and permissions.

What to watch out for

Do not put secret or personal data in SKILL.md or in the reference files. Skip real customer data, internal data structures and confidential documents. Use made-up or anonymized samples instead. The file should also state what data the skill expects, what it produces and where it sends anything, so a security reviewer can check it quickly.
