Claude, Draft Content.

When Claude drafts marketing copy well, it is tempting to think it picked up a new writing talent. The video says otherwise: a skill is just a file Claude reads. Using the draft-content skill as the example, it opens the file and shows what the skill actually does, which is one specific job with a defined scope.

A skill is a file Claude reads

The video defines a Claude skill as a folder Claude reads before it works. For this one, the SKILL.md file holds the entire instruction set in plain language, with nothing hidden. Claude reads the file and then acts. The video puts it this way: the file is the program.

How Claude runs it

The instructions live in a steps section. Claude reads each step in order and runs it from start to finish. There is no branching unless a step says otherwise. This makes the skill predictable, because the sequence of actions is written down in advance.

The one job: marketing content for specific channels

Draft-content has one job. It drafts marketing content with channel-specific formatting and SEO recommendations attached. The video lists the kinds of content it covers:

• blog posts
• social media
• email newsletters
• landing pages
• press releases
• case studies

Three moments the skill is written for

The file is written for three situations: writing any marketing content, generating headline or subject-line options, and adapting a message for a specific platform, audience and brand voice. Outside those three moments, the video says the file has nothing to say. That scope is the point of the lesson. A skill is not a new writing talent; it is one file doing one job.

What the video does not claim

The video limits itself to this one skill's design. It does not claim that every Claude skill is structured this way, and it makes no claim about how effective the SEO recommendations or channel formatting are beyond what the skill's own scope statement says. Its consistent claim is that the same input gives the same output each time you run the skill, and only for the content it is scoped to write.

The prompt shown at the end

The closing prompt asks Claude to draft a blog post announcing a product update, formatted for both a company blog and a LinkedIn post. It then asks Claude to read through how it would write that and to walk through what it is about to do before doing it. The video notes that watching the plan come first is how you actually see a skill's scope, not just its description.

Key takeaways

• A Claude skill is a folder Claude reads before it works, not a new talent.
• The draft-content skill is a SKILL.md file holding its whole instruction set in plain language.
• Claude reads each step in order and runs it start to finish, with no branching unless a step says so.
• The one job is drafting marketing content with channel-specific formatting and SEO recommendations.
• Covered content includes blog posts, social media, email newsletters, landing pages, press releases and case studies.
• It is written for writing marketing content, generating headline or subject-line options, and adapting a message to a platform, audience and brand voice.
• Outside those three moments the file has nothing to say.

Try it yourself

Use the video's prompt on a real task of your own, such as drafting an announcement for a company blog and a LinkedIn post, and ask Claude to describe its plan before it writes. The plan will show how the skill's scope shapes what Claude does and where it stops.
