Alias Bot – Replace repeated @mentions in Slack with channel aliases

Summary: Alias Bot enables Slack users to create channel-specific mention aliases that expand to predefined user groups, reducing long @mention chains and minimizing tagging errors. It works without org-wide user groups or admin setup, making it suitable for rotating or temporary teams.

What it does

Alias Bot lets users define aliases like !reviewers that expand to multiple @mentions scoped to a specific Slack channel, simplifying tagging and ensuring the correct people are notified.

Who it's for

It is designed for teams with rotating or short-lived groups such as on-call, release, or incident teams who need flexible, channel-scoped mentions.

Why it matters

It addresses the problem of cluttered mention chains and missed or incorrect tags in Slack channels without requiring org-wide group management.
