Hey @Joe,

`pre-command` and `post-command` are one of the hooks an agent runs in the context of running a job. The docs describe the purpose of each.

You have a few options on how to get them to execute for a job. The simplest option would be to write a [hook in your repository](https://buildkite.com/docs/agent/v3/hooks#hook-locations-repository-hooks). If you create an executable script in `.buildkite/hooks/pre-command`, the agent will find that and execute it at the pre-command stage of the job lifecycle. The same goes for `post-command` or any other hooks that can be read from the repository (the docs show which ones)
