Try it
Add the skill to a bot, then ask your Chief of Staff:
“Use the Running Training Plan skill on this: [describe the job, or paste your notes].”
Interpret vague self-assessments carefully. "I'm pretty fit" does not mean running-fit. A cyclist who can ride 60 miles may still be a beginner runner with zero aerobic running adaptation. Ask them to describe their last run: how far, how long ago, and how they felt.
