## Where to run commands
To increase visibility, we recommend that GitLab team members run feature flag
related Chatops commands within certain slack channels based on the environment
and related feature. For the [staging](https://staging.gitlab.com)
and [development](https://dev.gitlab.org) environments of GitLab.com,
the commands should run in a channel for the stage the feature is relevant too.
For example, use the `#s_monitor` channel for features developed by the
Monitor stage, Health group.
For all production environment Chatops commands, use the `#production` channel.

This can be removed through ChatOps:
When a feature gate has been removed from the code base, the feature
record still exists in the database that the flag was deployed too.
The record can be deleted once the MR is deployed to each environment:
```sh
/chatops run feature delete some_feature --dev
/chatops run feature delete some_feature --staging
```
Then, you can delete it from production after the MR is deployed to prod:
```sh
/chatops run feature delete some_feature
```
