Most of us have one task we do every single week that drains an hour of our life. The weekly report. The client update. The meeting recap. Same structure, same format, same energy spent every time. I kept thinking there had to be a way to bottle that workflow once and reuse it forever.
Then I came across this incredible 60-minute walkthrough from a LinkedIn creator who breaks down exactly how to build your own Claude Skill from scratch. The post lays out a full hour, step by step, and by the end you have a working Skill that fires on demand. I was genuinely impressed by how clean the process is once someone shows you the path.
Here’s the full breakdown from this savvy professional, organized into the same time-blocked structure they used. Save it. Send it to your team. Bookmark it for the next rainy Sunday afternoon.
The Setup (Before The Clock Starts)
Before you touch the timer, get the basics in place. The author keeps this part dead simple:
- Open the Claude desktop app on your machine.
- Click the Cowork tab at the top of the interface.
- Make sure you’re on the Pro plan. It’s $20 a month, and the original poster vouches that it pays for itself fast.
That’s it. You’re ready to start the clock.
0 to 10 Minutes: Find The Skill-Creator
Open Cowork and locate the skill-creator. The expert recommends pairing it with Opus 4.7 plus Extended thinking for the best output quality. Select the folder where you want your new Skill to live.
Then drop in this prompt:
“Use the skill-creator to help me build a skill for [your most repeated task].”
Pick the task that eats your week. Reports, summaries, code reviews, whatever you do over and over. That’s your candidate.
10 to 25 Minutes: Answer The Interview Honestly
The skill-creator asks you a series of questions about how you want the Skill to behave. The mind behind this guide stresses one thing above all: be specific.
Look at the difference:
- Useless input: “I write reports.”
- Skill that actually works: “Weekly reports, headline metric first, 3 sections max, next steps at the end.”
Vague answers produce vague Skills. The output of this stage is a folder containing a SKILL.md file with your trigger and instructions baked in. If your description is fuzzy, the Skill won’t fire when you need it.
25 to 35 Minutes: Run The Evaluation
Here’s the part I love. Claude automatically generates an eval to validate that your Skill works the way you described it. Click “View the eval results” to test it before you commit anything to your system.
Write the test once. It runs every time. That’s the whole power move.
35 to 45 Minutes: Install And Test In The Real World
Time to make it live. The contributor walks through this part in three quick moves:
- Save the Skill folder to your machine.
- Go to Settings → Capabilities → Skills → Upload.
- Type a request that should trigger the Skill and watch it fire.
If it fires cleanly on the first try, you nailed the description. If not, back to step two.
45 to 55 Minutes: Iterate And Debug
This is where most people quit too early. The original poster gives a brilliant little debug protocol:
- Try 5 different phrasings of the same request. Does the Skill fire every time?
- Try 3 totally unrelated requests. Does it stay quiet and not interfere?
- Ask Claude directly: “When would you use this skill?” It will quote the description back at you, and you’ll instantly see what’s broken or ambiguous.
That last trick is gold. It surfaces every weak word in your description without you having to guess.
55 to 60 Minutes: Browse Plugins And Stack More Skills
You finished one Skill. Now you can borrow from the community. Inside the Claude desktop app, head to Customize → Personal plugins → Browse plugins. A plugin is just a bundle of Skills somebody else already built and tested. Download, install, test, repeat.
The Pro Tip That Changes Everything
The single best line from this LinkedIn user is buried near the end of the post, and it deserves its own spotlight:
Always add “Do NOT use for…” lines to your description. Negative triggers matter more than positive ones.
Most people only describe when a Skill should fire. The pros describe when it should stay silent. That’s the difference between a Skill that helps and a Skill that hijacks every conversation.
One more bonus from the creator: Skills are portable. The same SKILL.md file works on Claude, Gemini, and ChatGPT. Build it once, run it across every tool you use.
Why This Matters
I think this is a real shift in how we work with AI. Instead of rewriting the same prompt every week, you encode your taste, your structure, and your standards into a file that fires automatically. An hour of setup buys you back hours every single month.
