Teach your agents how the work is done.
Skills are reusable instructions an agent follows for a job: how to triage a bug, roll back a deploy or chase a payment. Add one to any agent.
Cut a release and write the notes
Tag a release from something already proven green, with notes written for the people who use it rather than the people who wrote it.
Find out why CI is failing
Read a red build down to the actual assertion or gate that failed, and say whether it is this change, the branch it sits on, or the pipeline.
Review a pull request
Read a change for the failures that matter in this codebase and leave a review somebody can act on without a second round.
Have a way of working worth keeping?
Write it down once as a skill and every agent you build can follow it.
