Claude Skills I Actually Use as a Consultant

Claude’s Skills feature offers packaged capabilities, defined by SKILL.md files, that carry out repeated tasks at the same quality every single time. I don’t treat this as an abstract concept in my consulting work — I use it as four concrete tools I run every single week: a standardized Google Ads report, a fixed-template GA4 summary, a check that keeps brand voice consistent in SEO content, and the discipline of taking a backup before making any change to a live system. In this post I walk through each one with how I actually use it and real examples.

Locking a Single Format for the Weekly Google Ads Report

Managing 43 Google Ads accounts on my own, I run into the same question every week: how did spend, conversions, and cost change in this account compared to last week? Instead of writing the answer from scratch every time, I use a skill that fixes the structure of the report — which headings it will have, which metric falling below which threshold gets flagged with an “attention” tag, and in what order campaigns get listed are all defined up front. When I run the skill, the output comes back with the same skeleton for every account; only the numbers change. It might look like it’s doing the same job as a thirty-second “prepare a report for this account” request, but the real difference is in the discipline: if I wrote the same instructions by hand every time, by the third week I’d forget a heading or interpret a threshold differently. The skill locks that down.

Summarizing GA4 Data With the Same Template

There’s a similar trap on the GA4 side: summarizing the same property’s data one week by channel breakdown, the next by device breakdown, and another week with some random chart. The GA4 skill I use locks down the shape of the output — first the key events (things already defined in GA4 like clicked_phone, clicked_whatsapp), then channel-level traffic change, then the top-traffic pages, and finally the percentage change against the previous period. The skill also prevents a small but annoying mistake: reporting a one-day traffic spike (usually a bot or a campaign test) as organic growth. That rule is written into the skill itself; I don’t have to remember it every time.

Not Losing Brand Voice in SEO Content

The real risk when writing content isn’t wrong information — it’s tone. First person, concrete numbers, no exaggeration — all three need to hold up as well in a piece’s thirty-fourth paragraph as in its first. The SEO content skill I use automatically filters out certain patterns while writing: number-free praise like “industry leader” or “best solution”; exaggerated words like “unique” or “revolutionary”; and any attempt to name-drop a client (this is where the “only numbers can be published” rule comes from). The skill doesn’t make a piece perfect in one pass — but it strips out most of the patterns I’d otherwise have to hunt down one by one in the first draft.

Backup Discipline Before Any Change to a Live System

This isn’t the skill that saves the most time — but it’s the one that costs the most if it gets skipped even once. Before making any write operation on a live WordPress site: take a git snapshot, export a database backup, verify the target server and database, and state the change and the rollback path in writing. Under time pressure, any one of these steps can easily get skipped — you might think “it’s a small change, no need for a backup.” The skill turns this from a choice into a gate: no write operation happens until these steps are complete. Manually remembering this discipline every single time across twelve different sites isn’t realistic.

An Observation From the Field: When to Use a Skill, When a Simple Prompt Will Do

There’s a simple test for whether a task is worth turning into a skill: if I’m writing the same instruction for the third time, that’s a signal. The weekly report, the GA4 summary, and backup discipline cleared this bar easily — they repeat more than once a week, sometimes more than once a day. But honestly, not every repeated task deserves to become a skill. Building a skill for something I only do once a month, where the context changes every time, doesn’t pay for the setup and maintenance cost — a plain prompt is enough there, and even faster. A skill’s cost isn’t zero: you have to write the SKILL.md file, test edge cases, and keep it up to date over time (I covered this process in detail on How to Write a SKILL.md). Only genuinely repeated work pays back that investment. For a broader framework, see the Agentic AI Guide hub page.

You Can Ask Me for This Work

If your own work has a weekly report, a regular data summary, or a task that repeats in a fixed format, I can turn it into a Claude Skill and set it up for you. Typically 2 hours to 2 weeks of work, remote, billed hourly. For broader AI consulting scope, check out the Your Own AI Assistant page.

Frequently Asked Questions

What exactly is Claude Skills?

Claude Skills is a capability package defined by a SKILL.md file that predetermines the steps, format, and rules for how a specific task will be done. The difference from a normal prompt is that the instruction is permanent and reusable, not one-off. For more detail, see What Is Claude Skills.

How long does it take to write a skill?

A simple skill (single format, a few rules) can be written and tested in an hour or two. A skill involving multiple steps and approval points, like backup discipline, can take a few days, because edge cases (wrong server, missing backup) need to be tested.

What kind of work do skills make the biggest difference on?

They make the biggest difference on weekly or daily repeated work that requires format and rules: report generation, data summaries, content review, checklists before making a live-system change. On one-off tasks or ones where the context keeps changing, the payoff is limited.

Does using a skill remove human oversight?

No. A skill standardizes the output, but the approval step — especially for live-system changes — is written into the skill itself. In other words, the skill isn’t there to skip a human’s approval, it’s there to make sure the approval is never forgotten at the right moment.
