Skills: package your taste
Turn your brand's hooks, captions, and voice rules into a file Claude reads every time, so output stays on-brand without you repeating yourself.
The first ad Claude writes for you might be great. The tenth one, without help, probably drifts: different tone, different structure, a joke that doesn't fit your brand. That's not a model problem. Claude has no memory of what 'good' looked like the first nine times unless you give it one. A skill is how you give it one.
A skill is a written file, instructions, examples, rules, that Claude reads before it does a specific kind of task. Instead of re-explaining your caption format or your hook style in every conversation, you write it once. From then on, Claude checks that file whenever the task matches, and the output comes back sounding like you instead of sounding like a generic AI assistant.
None of this requires a settings menu. A skill is just a plain-text file that lives wherever your Claude setup keeps them, and it gets pulled in automatically whenever a task matches what it covers. You don't call it by name mid-conversation, you just ask for the caption or the hook, and the taste comes with it.
What actually goes in one
- The pattern, not just an example. What makes your best hook a hook, spelled out as a rule, not just one sample to copy.
- A short list of what not to do. The AI-tells and off-brand moves you're tired of editing out by hand.
- Two or three real examples of output you've already approved, so Claude has ground truth, not just a description.
- The specific vocabulary and structure your brand actually uses. Where the CTA goes, how long the caption is, what gets said in the first line versus buried at the bottom.
- A narrow scope. One skill per repeatable task (hooks, captions, replies) rather than one giant on-brand file that tries to cover everything and ends up vague.
Where ecommerce operators actually use this
- Hook engineering. The first two seconds of a UGC video is the whole game, and a skill can encode exactly which reaction, which prop, which first line has worked for your product before, so every new video starts from what's already proven instead of a blank page.
- Caption and hashtag style. The voice, length, and CTA structure for your posts locked down so it doesn't drift between whoever's prompting that day.
- Brand voice for replies and DMs. Comment-backs, quote posts, and customer messages that need to sound like the same company every time, not like whatever tone the model defaulted to.
- Ad iteration formulas. When a creative starts fatiguing, a skill can define exactly what a new angle means for your brand instead of Claude guessing at a random new hook.
A skill is usually a short file with a name, a one-line description of when to use it, and the rules underneath. Roughly:
Name: brand-caption-style
Use when: writing a post caption for [brand]'s ads
Rules:
- Hook in the first line, under 8 words
- CTA is always a comment-keyword, never a link in the caption
- No more than 3 hashtags, never generic ones
- Match the tone of these approved examples: [paste them]
The exact file format varies slightly by surface. claude.ai, Claude Code, and Claude Desktop each package skills a little differently, so check the skill docs for the one you use.Signs you need one
- You're typing the same reminder into every prompt: 'remember, keep it under 8 words,' 'no hashtags past 3.'
- Two people on the team get noticeably different output for what should be the same kind of post.
- You keep fixing the same kind of mistake in every draft Claude sends back, the same joke, the same wrong CTA placement, the same off tone.
How to build your first one
- Pull three to five pieces of output you've already approved. Real captions, real hooks, real replies you'd actually publish.
- Look at what they have in common that a generic prompt wouldn't produce on its own. That's the rule you're actually trying to capture.
- Write it down as instructions, plus the examples themselves as reference.
- Test it in a brand-new conversation, not the one you built it in. That's the only way to know if the file alone carries the taste.
- When Claude gets it wrong, don't just fix that one output. Fix the skill, so the same mistake doesn't happen again next time.
The payoff
A skill is leverage on your own judgment. You make the good call once, write down why it was good, and every future output starts from that instead of from zero. The operators getting the most out of Claude aren't the ones with the cleverest single prompt. They're the ones who stopped repeating themselves.
