Build Your First Skill
A skill is just instructions you write (conversationally) that Claude follows to do something repeatedly. Here's how to build one in under an hour.
Pick Your Task
The golden rule: Pick something boring that you do at least once a week.
Good examples:
- Write a weekly status update email
- Summarize the past week's Slack messages
- Draft a daily digest of important emails
- Update a tracking spreadsheet
- Create a competitive intelligence report
- Auto-draft replies to common email patterns
Bad examples: Things that happen once. Things that change every week. Things that need human judgment.
The 5-Step Process
Do the task yourself once. Write down every single step. Be obsessively specific. Don't skip anything because "it's obvious."
Example: Instead of "write a weekly summary," write:
This is your script. Claude will follow it.
Don't use an existing chat. Start fresh. This keeps things clean and skips the noise.
In Claude Cowork, click "New Task" and select the project you want this in (or create a new one).
Use this prompt (it's in the FAQ). It tells Claude exactly what format you need. Start a conversation with Claude using this template:
Claude will ask clarifying questions. Answer them. This is normal. Examples:
- "Should this run every Monday at 9am or 7am?"
- "Who should get the email — just you or the whole team?"
- "Should it look like it came from you or from a bot?"
Answer everything. This is how Claude learns to automate it correctly.
Claude will write out a markdown file (.md). This is your skill. Don't worry about understanding it — you don't need to. Just say "save the skill" and Claude handles everything.
Done. It runs automatically now.
Real Example: Weekly Email Digest
The task: Every Monday at 7am, send yourself a digest of important emails from the past week.
Step 1: Write It Out
Step 2-3: Open Chat & Paste Prompt
"I want to create a skill for weekly email digest. Here's what I want: [paste above]"
Step 4: Claude Asks
"Who counts as 'important people'? Give me a list or a rule."
You answer: "Founders, board members, and clients."
Step 5: Skill Created
Claude writes the skill. You click save. Every Monday morning, you get your digest automatically.
Common Mistakes (Avoid These)
- Starting too ambitious: Pick something small. A 10-minute task. Get one win first.
- Being vague: "Write a summary" is not specific. "Summarize the past 7 days of Slack #engineering into 3 bullets" is.
- Not being honest about time: If it only takes 5 minutes, don't automate it yet. Wait until you have a task that takes 20+.
- Treating the skill like code: You don't need to "understand" the markdown. Claude handles it. Trust it.
- Not testing it: Before scheduling it for production, run it once manually and review the output.
The Real Power
One skill saves you 1 hour a week = 50 hours a year.
Five skills = 250 hours a year.
That's 6 weeks of work you just got back.
And you only had to think about it once.
This is why people with Cowork are so much faster. They're not smarter or working harder. They're just not doing stuff that a computer can do.
