Here's one of my early skills, a simple email brief.
Like a lot of people I spend time catching up on emails because they pile up so fast. So I made a brief skill that sends me a summary of basically High priority, Medium, and low/skippable emails.
One adjustment I made was setting up message forwarding because I actually have two work emails and then adding that context to the skill so it knows everywhere to check.
Then I was able to pull the personal parts of my context out of the skill to make a team-wide skill where they can fill in their individual role goals and things that are priorities for their skill, based off of the same scaffolding that's at the core of this brief so they get like an 80% head start on an email brief skill!
