📖 What Skills Are
Skills are pre-built capabilities you invoke with a /skill-name command inside Claude. They're not just prompts — they run specialized logic to produce structured outputs like real PowerPoint files, formatted PDFs, or data spreadsheets.
The invocation pattern is always the same: /skill-name [instructions]. Claude reads your context, applies the skill, and delivers the output file.

🚀 5 Real Examples
Example 01
Turn a brief.md into a pitch deck in 30 seconds
Write your project brief in markdown, then invoke /pptx. Claude structures it into slides with titles, bullets, and a professional theme.
prompt/pptx Create a 10-slide investor pitch deck from brief.md. Use a dark professional theme. Include: problem, solution, market size, product demo, traction, team, ask.
Example 02
Export a weekly report as a formatted PDF
After Claude writes your weekly summary in markdown, convert it to a polished PDF with a cover page and table of contents.
prompt/pdf Convert report.md to a professional PDF. Add a cover page with "Weekly Engineering Report — April 2026", a table of contents, and section headers. Company name: Pulse.
Example 03
Build a data spreadsheet from raw notes
Give Claude messy bullet-point data and let /xlsx structure it into a proper spreadsheet with headers, rows, and formatting.
prompt/xlsx Take these 25 customer feedback items and create a spreadsheet with columns: Customer, Date, Sentiment (Positive/Neutral/Negative), Category, Summary. Sort by sentiment.
Example 04
Chain skills — markdown → PDF → email attachment
Skills chain naturally. Write the content, export to PDF, then hand the file path to another tool or agent to send.
Write report.md
→
/pdf export
→
report-2026.pdf
→
Send via Notion/email
prompt/pdf Convert report.md then save to output/weekly-$(date +%F).pdf
Example 05
Create a reusable custom skill with /skill-creator
If a skill you need doesn't exist, build it. /skill-creator lets you define the invocation name, input format, and output behavior.
prompt/skill-creator Build a /standup skill that reads TASKS.md and generates a daily standup update in this format: Done yesterday, Doing today, Blockers. Keep it under 5 bullet points total.

Chain tip: Skills produce files. Agents can pick up those files and act on them — post to Notion, email to a team, push to GitHub. Connect skills to plugins for end-to-end automation.
