What one looks like
Where a skill lives
A skill sits in theskills/ folder of one memory level, and that decides who has it: one client, one worker, or the whole company. A skill of the same name in a narrower level shadows the broader one, so Acme can have its own way of doing status notes without anyone editing the shared skill. Your skills always beat Ergoly’s.
Writing one yourself
- Write the SKILL.md in Claude Code, Cursor, or any editor.
- Put it in the right level: the worker’s Knowledge tab, New file or Upload a file under
skills/<name>/, or push it through the API. - The worker has it on its next conversation. There is nothing to deploy.
Workers writing their own
Worth knowing. Around thirty skills, a worker is getting broad. Around fifty, split it into two workers with two roles. See Role.
