Interesting their X post mentions "pre-built Agent Skills" but it's not on the webpage. I wonder if they will give you the ability to edit/add/delete Skills, that would be phenomenal.
Edit: found it on their other blog post https://www.anthropic.com/news/advancing-claude-for-financia...
You can add and customize skills in claude.ai and other surfaces
Sorry, I'm well aware of skills, but wanted to know how specifically they would be used in this Excel extension
